Landing time

I believe the guy in the live stream said the touchdown was at 10:14:39 PDT (05:14:39 UTC). Kaldari (talk) 06:24, 6 August 2012 (UTC)

Yeah, I think I heard that too. But the landing time will soon be confirmed in many reliable sources, and we'll get the article times all correct. N2e (talk) 06:38, 6 August 2012 (UTC)

Would the landing time be the time that Curiosity's data reached Earth, or the actual time it landed, approximately 14 minutes earlier?    → Michael J Ⓣ Ⓒ Ⓜ 18:53, 6 August 2012 (UTC)

It is the time of signal reception on Earth. BatteryIncluded (talk) 18:56, 6 August 2012 (UTC)

5:14:39 UTC as a landing time is probably about 3.5 minutes wrong; see my notes in the TALK section of the MARS SCIENCE LABORATORY article. Actual landing time was probably around 5:17-5:18 UTC SCET (SpaceCraft Event Time), or 5:31-5:32 UTC ERT (Earth Received Time), and both of these times are probably accurate to no more than +/- 1 minute. The OneWay Lightspeed Time (OWLT) at the time of landing was given by JPL as "13.8 minutes" in a pre-landing press release (see my reference in TALK/MSL), which would be 13 minutes 48 +/- 6 seconds, although I'm sure it's known to a far greater accuracy than that. Remember that SCET + OWLT = ERT, and times must be specified not only as PDT or UTC, but also as SCET or ERT. As I noted in TALK/MSL, for now the landing time should probably read only as 5:17-5:18 UTC SCET, until reliable sources (i.e. NASA/JPL sources) come up with a to-the-second set of numbers. Could someone routinely working on both articles make the appropriate changes? Many thanks. Lanephil (talk) 07:09, 7 August 2012 (UTC)

Whichever landing time has a source should probably be inserted into the introduction of the article, rather than just the info box. Both articles for Spirit rover and Opportunity rover use Ground UTC, and a nod should probably be made for the time format to be consistent among the Mars rover articles, when possible. OliverTwisted ^(Talk) (Stuff) 06:44, 8 August 2012 (UTC)

Agree with OliverTwisted. The 5:14:39 UTC SCET landing time currently listed is currently sourced to two *NON*-NASA sources (Spacewatch101 and a blog at Scientific American). As I noted in my comments in TALK/MSL, there are currently two NASA/JPL (so presumably "official") landing times, 1031 pm PDT ERT and 1032 pm PDT ERT (and I list the URLs there). The current wikipedia listing of "5:14:39 UTC SCET" in both the MSL and CURIOSITY articles is clearly wrong, and embarrassingly overly precise; the 1031 or 1032pm PDT ERT times given by NASA/JPL are accurate (per NASA/JPL) only to within one minute (for reasons, again, I note in my TALK/MSL posting). More accurate times will undoubedly be released sometime in future; but the current "5:14:39 UTC SCET" does really need changing. I hesitate to make the changes myself, as others have worked hard on these wikipedia articles - could one of the primary authors do so? Many thanks. Lanephil (talk) 18:58, 8 August 2012 (UTC)

I ignore what SCET and ERT stand for. Am I correct in that the convention in Wikipedia is to report the time of signal reception on Earth in UTC? If you agree on that, you could stop agonizing on the "real" landing time debate. Just my 2 cents and stepping back. BatteryIncluded (talk) 19:12, 8 August 2012 (UTC)

OK, we now have definitive information and sourcing for the landing time. The 15:14:39 UTC (SCET) landing time currently used is definitely wrong, and the origin of the error has been identified. See the TALK page at the MARS SCIENCE LABORATORY for details. The landing time (with a definitive NASA source) should be: year 2012, day 219 (Aug. 6), time 05:17:57 Spacecraft UTC (that is, SpaceCraft Event Time, SCET). Translation into Event Received Time (ERT) on Earth involves knowing the One Way Lightspeed Time, which is approximately 14 minutes, but for which we do not yet have a well-sourced to-the-second number. We *do* have a well-sourced (NASA-sourced) approximate ERT landing time of 10:32pm PDT, and that's what should be used for now. All detailed references are in my notes in TALK/MARS SCIENCE LABORATORY. Could someone who has been working routinely on the CURIOSITY ROVER article make these fixes? Many thanks. Lanephil (talk) 05:41, 9 August 2012 (UTC)

Fixed, on both Curiosity rover and Mars Science Laboratory articles. OliverTwisted ^(Talk) (Stuff) 07:42, 9 August 2012 (UTC)

Image

Re "File:NASA Curiousity, first image without dust cover.jpg|thumb|First image from Curiosity rover" - Shouldnt the image be moved to Wikimedia Commons? I dont know how.(mercurywoodrose)99.101.139.124 (talk) 06:44, 6 August 2012 (UTC)

Brief followup - moving "File:Mars_Science_Laboratory_Lander_from_HiRISE.JPG" to Wikimedia Commons may be moot since this may have already just been done w/ "File:Curiosity_parachute.png" - updated the article image accordingly w/ this newer one - Enjoy! :) Drbogdan (talk) 19:14, 6 August 2012 (UTC)

The image in the 'Rover' section is labeled in french (not that you'ld notice from a casual look). I don't believe there exists a corresponding english labeled version yet, but it would be nice if someone made the effort to provide a corresponding english version. --71.214.218.217 (talk) 14:47, 7 August 2012 (UTC)

Robot arm

From above:

"rover article needs a section on the robot arm. -84user (talk) 12:38, 6 August 2012 (UTC) "

I agree. I am starting a new section on the Talk page with your comment to ensure it gets appropriate attention from all the eyes that will be on this article in the next few days and weeks. Cheers. N2e (talk) 15:00, 6 August 2012 (UTC)

After looking at [1] I wonder if we should have a "Sampling system" sub-section under the Specifications section? The robot arm is one of several components in that system (which I'm only reading about now for the first time), there's also the drill, spare drill bits, soil scoop, "Organic Check Material" and so on. The best examples for such a section I've seen are Roboterarm und Probengewinnung from the German wikipedia and the somewhat more structured Le bras porte-outils from the French. -84user (talk) 17:02, 7 August 2012 (UTC)

Pu pellets size

The article says that the plutonium pellets are "each about the size of a marshmallow." Perhaps also a less US-cultural-specific comparsion in metric units should be added for readers from overseas countries, where this confection is almost unheard of. The article on marshmallow at this moment does not give an answer, therefore I ask: How many centimetres is an average piece of it? --Miaow Miaow (talk) 22:31, 6 August 2012 (UTC)

 Done - A marshmallow ≈20 cm³. BatteryIncluded (talk) 00:01, 7 August 2012 (UTC)

Mars Rover Landing Game

I think we can mention this somewhere in the article NASA and Microsoft released one small step for gamers. "Mars Rover Landing" is a free downloadable game on Xbox Live that uses body motions and Kinect for the Xbox 360 to simulate the "seven minutes of terror" landing sequence. http://www.newsday.com/business/technology/warp-pipe-1.1521604/mars-rover-landing-with-kinect-for-the-xbox-360-1.3886958 -Abhishikt (talk) 23:37, 6 August 2012 (UTC)

Service life

Article says that the power supply is suppused to last ~14 yrs but I didn't see anything about how long they are expecting the rover itself to continue operating.

The rover's components are designed & tested to last at least 4 Earth years, but the primary mission goal is set at 2 years. It is likely and expected that there will be mission extensions as done with Spirit & Opportunity until the rover or its instruments cease to function. By the way, the power source has a "minimum" life of 14 years, two of which were spent in storage caused by the launch delay. Cheers. BatteryIncluded (talk) 17:28, 13 August 2012 (UTC)

References' format

What is happening with the references format? When i click on "edit" of that section, there is a long list of all references used in the article. By default, inserting {{reflist}} is the only information required in this section! BatteryIncluded (talk) 19:36, 7 August 2012 (UTC)

It happens that some genious with too much initiative decided to be original and "fixed"(sic) all leading references and pasted them in the reference section, violating not only common sense- but WP:ASL:

“ citations appear in a single section containing ONLY the <references /> tag or the {{reflist}} ”

There have been too many editions since then, that a simple "undo" will not do it. I will restore them slowly as time permits. Cheers -BatteryIncluded (talk) 22:56, 7 August 2012 (UTC)

Speed of radio communication

I've added data about the speed of communications between Curiosity, the orbiters and the Earth. Such data was deleted for no reason, while a minor part of what I've written was kept, but without the source. I would like to understand the reasons for this, since I thought this kind of info to be relevant. Eliasams (talk) 19:43, 7 August 2012 (UTC)

Sorry, that may have been me; I expanded that section in the MSL article and just copyed/pasted it here. I will take another look at the "speed" part and the source you mention. Please stand by. BatteryIncluded (talk) 19:48, 7 August 2012 (UTC)

Thank you for assuming good faith and civil discourse. I replaced the information you entered with the sources. That section also needs a bit of care, and you seem to understand telecoms, so please feel free to fine tune it. Again, thanks. BatteryIncluded (talk) 19:57, 7 August 2012 (UTC)

No problem. Thanks for being urbane and corteous, and adding my contribution back. I'll fine tune/add more info whenever I find more from reliable sources. Eliasams (talk) 19:59, 8 August 2012 (UTC)

Cost

As an American taxpayer, I'd like to know the total cost of this mission. Surely that is a relevant data point. Perhaps that information has been omitted so as not to draw attention to the huge expenditure of resources. I notice that the total cost for the mission is mentioned as $2.5 billion on the MSL page. http://en.wikipedia.org/wiki/Mars_Science_Laboratory 66.92.0.146 (talk) 21:07, 7 August 2012 (UTC)

Typically NASA mission costs include research, development, deployment, and support through the mission life. That's why it's significant, for example, that the Mars rover missions for Spirit and Opportunity were extended: Without additional funds the successful rovers would largely be ignored, new commands would not be sent, and the support staff would be fired or reassigned.

The total cost of the mission given in the Mars Science Laboratory article as $2.5 billion can be relied on, as it's a matter of public record. The reference given is in article [2] which makes for broader information, vis-a-vis your question.

There are other interesting cost factors. Russia, for example, which contributed the pulsing neutron generator (Dynamic Albedo of Neutrons) to Curiosity is, of course, not required to say how much they spent at all. And in the case of Spain, an article seemed to suggest that the Spanish contribution was part of some trade deal, in which case the "cost" could be very difficult to determine, indeed!

Moreover, being familiar with life at NASA, I can say researchers often have plenty of time to be involved in other projects. Sometimes they consult, or sometimes they simply watch presentations as a matter of interest. That overhead is never calculated or placed in the budget.

So we'll never know how much the MSL cost, but it was at least $2.5 billion dollars of US taxpayer money. But as a NASA official at the first press conference (near Hollywood) wryly pointed out, the cost per person is $7, and that it was cheap for the movie that had been produced. Leptus Froggi (talk) 22:06, 7 August 2012 (UTC)

On a related note, why is it that the ChemCam section lists the cost for the component, when no other instruments do so. The phrasing makes it seems like someone associated with ChemCam is using Wikipedia for political purposes. Sanpitch (talk) 03:51, 8 August 2012 (UTC)

On Wikipedia, the most likely reason for content discrepancy between sections is not political motivation, but relying too heavily on the wording of the original source, which can be written by marketing teams. Hundreds of editors work on this article, each with access to their own sources. Please assume good faith when pointing out potential errors. I have removed the fraction of the ChemCam cost to the total budget, which was in fact, not encyclopedic information, but was quoted directly from the source. OliverTwisted ^(Talk) (Stuff) 07:00, 8 August 2012 (UTC)

Propose switching order of Landing site and Cultural impact

I think that in terms of overall information organization and presentation, the section on the landing site should probably appear above the section on the cultural impact of the landing, as that section is likely to grow and become a trivia farm fairly quickly. This may obscure the more scientific presentation of the information in the landing site section. OliverTwisted ^(Talk) (Stuff) 05:01, 8 August 2012 (UTC)

I concur, for the reasons you state. N2e (talk) 05:28, 8 August 2012 (UTC)

The most relevant and notable cultural impact will be the planetary science results; so please, lets keep that 'trivia farm' in check. Cheers, BatteryIncluded (talk) 06:51, 8 August 2012 (UTC)

How severe is the RTG failure?

According this NASA Inspector General report the RTG showed unexpected performance loss by the new developed thermocouples. As a result:

"However, as a cautionary measure, MSL Project managers have reduced the mission’s performance capabilities to processing 28 rather than 74 soil and rock samples and to traversing 4.5 kilometers rather than 20 kilometers."

Is that reduction still to expect? What is the actual measured electric power output of the RTG now? -- Carel A. Kraft (talk) 17:30, 8 August 2012 (UTC)

That is a report from last year - before launch. We can assume that the issue was addressed before the launch as the current mission status does not make mention of such (any) problem. Anyway, thanks for the heads up. Cheers, BatteryIncluded (talk) 17:55, 8 August 2012 (UTC)

Actually, this recent report suggests that the spacecraft was launched with that power issue. The plutonium degradation was unavoidablke after the 2-year delay, but the "unexpected" thermocouples' ineficiency may be the limiting factor to the RTG. The rover landed about 10km from the base of Mount Sharp, so traversing only 4.5 km would be quite frustrating to many. Having found nothing else online, I suspect that this may be a revised "minimum performance expectation" to declare a mission success. Thank you for bringing up this issue, BatteryIncluded (talk) 18:06, 8 August 2012 (UTC)

Update: NASA is observing more power output than expected.[3], [4], [5]. Since at this stage the thermocouples' performance do not seem to be an issue of concern, and there is no official word on any reduction the mission’s performance capabilities, I would not venture to incorporate that into the article. BatteryIncluded (talk) 16:07, 10 August 2012 (UTC)

Image Compression is not via JPEG

Talking of images... Curiosity does not use JPEG but JET's own ICER wavelet-based image compressor. Someone at NASA are getting their space probes mixed up. [6]--Aspro (talk) 13:45, 10 August 2012 (UTC)

Don't forget the rover has 17 cameras: HazCams (8), Navcams (4), MastCams (2), MAHLI (1), MARDI(1), and ChemCam (1). I doubt they all use the same compression format.

For any specs or performance of the Malin-made cameras, always quote Michael Malin, their designer and operator, that often appears in the NASA news breifings. Cheers, BatteryIncluded (talk) 16:24, 10 August 2012 (UTC)

All those cameras record RAW, they so they all use the same onboard computer (or its backup) with which to compresses images from each camera under commands from Earth. --Aspro (talk) 18:38, 10 August 2012 (UTC)

OK. Care to update the article accordingly? (+ references?) I am not literate on digital image compression and the likes. Thanks, BatteryIncluded (talk) 18:50, 10 August 2012 (UTC)

Etching a microchip?

Quote: "NASA afforded the general public the opportunity from 2009 until 2011 to submit their names to be sent to Mars. More than 1.2 million people from the international community did so; their names were etched onto a microchip which is now on the deck of Curiosity on the surface of Mars."

It it was a microchip, their names would be downloaded electronically, right? I doubt they would purchase a radiation-hardened microchip only to etch it. A solid plate gets etched. What is it? BatteryIncluded (talk) 00:20, 12 August 2012 (UTC)

Found specifics. Changed paragraph to read: NASA afforded the general public the opportunity from 2009 until 2011 to submit their names to be sent to Mars. More than 1.2 million people from the international community participated, and their names were etched into silicon using an electron-beam machine used for fabricating micro devices at JPL, and this microchip is now installed on the deck of Curiosity.[85] In keeping with a 40 year tradition, a Presidential Plaque was also installed, with the signatures of United States President Barack Obama and Vice President Joe Biden. Elsewhere on the rover is the autograph of Clara Ma, the 12-year-old girl from Kansas who gave Curiosity its name in an essay contest, writing in part that "curiosity is the passion that drives us through our everyday lives."[86] OliverTwisted ^(Talk) (Stuff) 02:04, 12 August 2012 (UTC)

Thank you for your curiosity! I was not able to find anything. These are the details that make an article a good article. Cheers, BatteryIncluded (talk) 02:32, 12 August 2012 (UTC)

Distance to Mars

The distance to Mars is about 35 million miles, but the article states that the rover traveled 350 million miles. I believe both the article and its CNN source must be in error. I do not have the time at the moment to correct the error and provide alternate sources. In a few days from now, if someone else has not made the correction, I will do so myself. EDIT: It appears that I might be mistaken about this, depending on the path taken and the relative planetary positions... BenMhWlk (talk) 17:12, 12 August 2012 (UTC)

IMAGE Filenames - how to decode?

Spirit and Opportunity Rover images were 'encoded' on the NASA website, allowing a user to pick out which camera,filter etc was used to generate the image - Curiosity seems to be using a different format - is the information available for Curiosity and can the information be placed here if so ? (Couldn't find the key on the NASA mini-site?) — Preceding unsigned comment added by Monowiki (talk • contribs) 17:32, 13 August 2012 (UTC)

I presume you mean this file name encoding. [7]. NASA/JET don't appear to have released this information yet. NASA usually hold a lot of this stuff back until their own NASA approved scientists have had time to study the images. Thus, they can claim the credos for any 'discoveries' before anyone else. As I mentioned above, the images wont be in JPEG's formats but .img (RAW) and .imq (compressed). --Aspro (talk) 02:12, 16 August 2012 (UTC)

This thought has just occurred to me. From looking at the image file names, the first early images where taken when it was in 'flight' mode. So your seeing the camera ID and the space time stamp (the number of absolute or atomic seconds since 1 January 2000) etc. Down on the Martian surface, the image file gives the number of Martian days into the mission (starting with zero) for the first four digits, the letters then give the camera ID followed by the frame number etc. Now that the 'surface' software has been installed, and Martian time into the mission has been sync'd on the rover clock, the next images should start showing more familiar file labels which will give the extra information such as filter, azimuth, Martian time, etc. I don't think this should go into the article yet as NASA doesn’t appear (at least I cant find anything) to spell all this out in one citable source. As this sort of labelling applies to the NASA family of rovers and other probes, perhaps it would be better to have a separate article on NASA image/data file names and file formats. It would be useful, especially to those students that wish to post-prosses NASA images for analysis. Comments?--Aspro (talk) 14:10, 16 August 2012 (UTC)

User feedback from the MSL and Curiosity articles

As a normal practice, I view the feedback left by users on the articles on Wikipedia. I thought I would copy some of the more recent comments, for discussion. I did not copy the user's IP addresses, for privacy reasons.

• 2 days ago: A lot of info on how Curiosity communicates with Earth. No info on how Earth communicates with Curiosity. Does it do so directly to rover or through various Mars orbiters?

 Done Already present in article: Curiosity is equipped with significant telecommunication redundancy by several means – an X band transmitter and receiver that can communicate directly with Earth, and a UHFElectra-Lite software-defined radio for communicating with Mars orbiters.

• 4 days ago: I was looking for scientific data regarding the skycrane hover tests. Surely the rockets themselves were tested at some point, surely hovering was acheived with supreme accuracy here on earth. And yet, I can find no information on the hover test whatsoever. I have been using internet search engines since well before google existed and I can find no evidence that skycrane testing was carried out at all, let alone simple static rocket tests for the vehicle.

 Done Batt provided as much info as was available on the MSL article talk page. Will monitor for more available info. OliverTwisted ^(Talk) (Stuff) 10:00, 16 August 2012 (UTC)

Images

The apparent trend seems to insert new images in this article daily. Even the spacecraft infobox is overloaded with 3 images. Although the article is enriched with prudent use of images, this rate is not sustainable, especially on a 2-year mission. What do you guys think on creating an imagery section with a gallery of most relevant images, similar to what was used on the Lunar Reconnaissance Orbiter? Cheers, BatteryIncluded (talk) 03:29, 9 August 2012 (UTC)

At present, this is all there is. As more images become available, some refinement should naturally occur. ←Baseball Bugs ^{What's up, Doc?} carrots→ 03:39, 9 August 2012 (UTC)

When there are more than one videos available, a Video section can also be created, similar to the Mars Science Laboratory article, and then the video can be dropped to the bottom of the article. Surely we should limit the info box images to 1 or 2 maximum. There are images available on Wikimedia Commons for further study. OliverTwisted ^(Talk) (Stuff) 03:43, 9 August 2012 (UTC)

True, but the entry video will always be relevant here (soon the high definition version), as well as the eventual 360° color panorama of the landing site. Everything else should be screened for relevance, and added to a small gallery. So far, it's fine. — Kieff | Talk 04:44, 9 August 2012 (UTC)

Two images and a video in the infobox? The user now has to scroll down half a page to even see any text in the infobox. OliverTwisted ^(Talk) (Stuff) 04:53, 9 August 2012 (UTC)

Adjusted the image captions in the infobox - maybe better? - please feel free to further adj, modify and related of course - Enjoy! :) Drbogdan (talk) 11:05, 9 August 2012 (UTC)

The captions are all better, regardless of where the pics may end up, so thanks! The picture currently appearing opposite the See Also section interferes with the Wikipedia Book template, which is normally placed in this section. I have temporarily moved the template to the External Links section, although this is not technically correct. The last image before the Reference section also offsets the spacing of the References section. I think we still have image overload, both in the infobox and throughout the article. OliverTwisted ^(Talk) (Stuff) 11:26, 9 August 2012 (UTC)

It seems we agree. The image overload will have to be addressed very soon with a gallery, probably before this weekend. I reckon that in the long-term we will have to display only the most relevant images, so we will may have have to set a maximum range. BatteryIncluded (talk) 12:56, 9 August 2012 (UTC)

Someone was WP:BOLD and exercised some restraint with the images. Huzzah! OliverTwisted ^(Talk) (Stuff) 23:58, 9 August 2012 (UTC)

As we noticed earlier, a new Wikipedia editor has taken the challenge to create the Timeline of MSL Curiosity mission. Although it needs lots of work on formatting, scope and quality, that page may eventually be our image repository of useful but non-key images inserted into Curiosity and MSL articles. Cheers, BatteryIncluded (talk) 16:14, 10 August 2012 (UTC)

If we were to move the "parachute image", currently in the instrument section to a left column orientation, the MARDI picture will be close to the MARDI section, and we can avoid a top to bottom image column. It is just a suggestion. I was viewing pages such as Mars Science Laboratory, Opportunity rover and Spirit rover, and they seem to be a bit more visually balanced than this article at this time. Also, there appear to be a few hidden images in the landing section as well as a few other sections. Should we keep these or delete them? OliverTwisted ^(Talk) (Stuff) 04:51, 14 August 2012 (UTC)

I would also reduce the size of the largest images and set them all to the same size for cleaner format. Cheers, BatteryIncluded (talk) 06:17, 14 August 2012 (UTC)

I'm wondering why there is a special section on "Wide images". Two image section seems excessive. Could they just be placed at the bottom of the "Images" section? Thanks, BatteryIncluded (talk) 15:46, 15 August 2012 (UTC)

I also noticed all the images are again aligned to the right. Is there a reason why we wish to deviate from higher-rated articles on the same topic which present the images in a more a balanced fashion? I love the images, but the page feels very "heavy to the right" with imagery, and the text does not "blend into" the images as smoothly as it does on other similar pages, avoiding a smooth transition from section to section. It appears as if the page is divided into two columns, one for text, one for images. Have we arrived here on purpose, or just through conflicting edits? OliverTwisted ^(Talk) (Stuff) 01:48, 17 August 2012 (UTC)

I've centralized the gallery because think it looks better on my browsers when the top of the page has scrolled out of sight -but you can left justify it again if you like. I will move the Orbiter image of the parachute descent to the Aerial gallery as well, since this stage of flight is not describe in the adjoining text where it is a present. I think that only appropriate images and data files that contribute to the text should accompany the text in a right, then left, then right, then left fashion. I'll make a start.--Aspro (talk) 15:27, 17 August 2012 (UTC)

The image gallery and video galleries look 500% better than they did at first, although mostly because there is 500% more content. Centering the galleries looks very good in my opinion, although I am not referring to any Wiki format guidelines when saying so. Alternating images is definitely a way to help readers "absorb" both images and text, without having to "stop reading" and "start looking" from one column to another. I will have to say, strictly as a personal preference, and not backed by any Wiki guideline, I much preferred the larger image of the rover drawing, with identifying captions pointing to each part. That was very informative, and I felt it looked better when it was a bit larger (when referring to the various sizes which were tried). However, I do believe we are on the right track, and thanks to all who are participating. OliverTwisted ^(Talk)(Stuff) 01:22, 18 August 2012 (UTC)

FWIW - I also prefer "the rover drawing, with identifying captions pointing to each part" - Seems better than the present rover image imo - in any case - Enjoy! :) Drbogdan (talk) 02:00, 18 August 2012 (UTC)

Yes, I'd like to see that color diagram back into the instrument section. Cheers, BatteryIncluded (talk) 12:31, 19 August 2012 (UTC)

It looks as if most, if not all, of the current image issues have been addressed. The article is more balanced and more appealing. The choice to include the enlarged rover diagram, with labeled instrumentation, makes all the difference in the mid-section of the article. Great job!

On Mars for

What gives with the big yellow box at the top? My objections:

• it looks pretty ugly (IMO)
• gives no extra information- the third sentence of the article says it landed on August 6 and I can do the math
• (Sols here) is meaningless without context- is it supposed to mean that I can see how many sols it's been by clicking the link? There's a little clock on that page, but the link target isn't at all focused on delivering that information. Plus the link text "here" is bad form.

Raw data link?

Recently Curiosity was shooting a laser at a rock and examining the spectrum of the light emitted in over 2000 wavelengths. [8] I know NASA features their raw feed for camera photos, but is there a raw feed for returned data from the instruments? (Chemistry seems the most important, but also things like the telemetry of how fast the crane descended, etc. would be interesting) Wnt (talk) 04:32, 20 August 2012 (UTC)

Although NASA is atempting to provide poplar RAW data like this: [9], I don't think telemetry data will be made available any time soon to anyone other than bona fide researchers and students. E.g:[10] The practical problem as I see it, is that the telemetry data from all the sensors most likely arrives (since NASA invented this system) multiplexed together in a series of 'frames' consisting of the 'measurand' identifiers (address codes if you like) and a value between 0-255. From these frames one can also tell in which time period the measurements where taken. I can't see why NASA would not want to keep it simple and just store this as a meaningless binary file. Therefore, a researcher would have to get the software tools as well, to turn this RAW data into a form that is meaningful to humans. On top of that, they might need a bit of previous experience to understand and adjust the values to the calibration points. Whilst for images, its just a Tiff like file, which you can even post-process on GIMP (but at only 8 bits). As you may well understand, NASA is on a tight budget and I can't see them spending the money it would cost so that just, you, I and my cat can satisfy our curiosity. The same reason probable applies to the other Rover instruments. NASA may release some spectrograph data files and other things that are easy for students around the world to analyze but we will have to wait and see. So the answer to your question is : I don't know of any other RAW data available at the moment other than images - and don't expect to.--Aspro (talk) 13:26, 20 August 2012 (UTC)

I'd think that if people could access the 'meaningless' binary files, very soon a few web entrepreneurs would win fame and fortune putting out apps and websites where this was converted to user-friendly form for curious browsers. Wnt (talk) 13:41, 20 August 2012 (UTC)

I won't comment any more on this subject as talk page is not a forum -other than to say: I tend to agree with you, that for the determined, the data would eventually yield its secrets -(especially if NASA provided all the documentation and software tool-kits required). However, that brings another problem: NASA would not be in control of the news release of any discovers made by independent individuals or organisations. I haven't seen it actually written down any where but it appears to be a golden-rule that although the data belongs to the US tax payer it remains firmly under the control of NASA unless they agree to release parts of it. Maybe someone here, has actually bothered to read the small-print on the agreements for outside organisations to sign before receiving raw data from NASA and so may know exactly what it says about the eventual publication of their analysis. Having read some of the terms and conditions from publicly funded bodies I can't imagine NASA would not have similar T&C's. It would be seen in NASA as politically (with a small p) embarrassing if the hoi poloi made discoveries that NASA and its partners missed. Crowdsourcing the data might be more efficient (as it was with Galaxy Zoo) but that was a very rare exception. Releasing MSL images within 24 hours gives NASA (has NASA themselves have stated) time to view the images and possibly hold them back. So the uploading of images received from MSL to the NASA website -even here- insures NASA keeps control of exactly what is released and when. If the US Gov wants NASA to achieve more at a lower cost, then maybe we (the hoi poloi) should petition them for more openness.--Aspro (talk) 13:20, 21 August 2012 (UTC)

I understand the motives for a delay in publication; but in some other situations (gene sequences) the raw data does eventually become publicly reviewable. Hopefully word of such a feed will eventually be heard, and if anyone hears it, please add it here when you do! Wnt (talk) 13:05, 22 August 2012 (UTC)

Scientific raw data is not like an image raw data. The chemical composition information has to be plotted, controls and standards analysed, background noise determined & removed, and finally interpreted. I am sure they will eventually have the chemical data available though peer-review publications. Then of course, if they find a Corona bottle or a photon torpedo we'll hear about if somewhat faster ;P Cheers, BatteryIncluded (talk) 15:02, 20 August 2012 (UTC)

Mars Descent Imager (MARDI) role on the Martian surface?

As the Mars Descent Imager (MARDI) is currently described in the article text, it is an instrument that has a role only on the spaceflight portion of the journey. I see no role described for this camera as part of the rover mission on the surface of Mars.

If that is true, then perhaps the entire section ought to be moved from the rover article to the Mars Science Laboratory article that describes the spaceflight and the spacecraft.

If that is not correct, and the camera has an ongoing role on the Martian surface, then we will need to find a source to describe that role and cite it. Cheers. N2e (talk) 19:20, 22 August 2012 (UTC)

Found a primary source with some information: "Throughout Curiosity’s mission on Mars, MARDI will offer the capability to obtain images of ground beneath the rover at resolutions down to 0.06 inch (1.5 millimeters) per pixel, for precise tracking of its movements or for geologic mapping. The science team will decide whether or not to use that capability." The source is [11]. Sounds like the manufacturer of the camera, which needed to be mounted on the bottom of Curiosity in order to record the final portion of the Mars descent, has emphasized that the camera could be used for something on the Martian surface, where it is pointed straight down at the ground. The source does not indicate that it will be used for that purpose. N2e (talk) 19:36, 22 August 2012 (UTC)

Interesting. I think that the important point is that the camera is still mounted on the rover and is available. BatteryIncluded (talk) 22:43, 22 August 2012 (UTC)

Dynamic Albedo of Neutrons

Can anyone point to a non-paywalled copy of the Litvak paper on the DAN experiment? I'd like to know more about how the neutrons are generated and how the data in this chart is collected. [12] Thanks much. --ChrisRuvolo (t) 13:08, 23 August 2012 (UTC)

This one ? [13] See alsoNeutron generator. Explanation of graph: A pulse of neurons penetrate the ground and some get reflected. The number that get reflected and measured is the Y axis. The deeper they go before getting reflected, the long they take to get to the sensor (or counter). That's the X axis. If some get absorbed by hydrogen on the way it will show up as a drop in counts at a time difference proportional to the depth divided by two. The neutron counter is on the opposite side of the Rover to the sender and is on the rear right hand side See:[14]. The high peaks on the blue line towards the left hand side near to the zero point suggests to me that it was being tested with the Rover on a concrete floor with hardcore below. Concrete is dense and so will reflect more neutrons than the Martian surface.--Aspro (talk) 15:53, 23 August 2012 (UTC)

Thanks, that looks like an earlier version of the paper. I was specifically referring to one of the references in the article: [15] which is from Astrobiology in 2008. I understood the basic idea of the neutron reflection, but was looking for more detail about this particular setup. Thanks much for the paper. I will print it off and read it on my way home tonight. Cheers. --ChrisRuvolo (t) 21:17, 23 August 2012 (UTC)

There was an entry in the media coverage/cultural impact section mentioning the Angry Birds game with Mars as the setting.

More information has been released which would indicate I may have been premature in my assessment.

Also, I found this as I was doing research. It's something that might make a quirky addition to, or as a caption in, the Timeline of MSL Curiosity mission article; but would just end up being trivia on the main article. August 9: "Curiosity awoke from her 'beauty sleep' today to the toe-tapping tune 'Good Morning' from the musical 'Singing in the Rain,' feeling healthy and refreshed and ready for a busy day of continued health checks and imagery," according to an Aug. 9 report on NASA's Mars Science Laboratory Website.

Hatnotes

Hatnotes are an eyesore and a distraction; a sometimes useful one, but not in this case. There is virtually zero chance that readers googling for either Mars Science Laboratory or Curiosity rover could end up on the wrong article, as the two titles are completely different. Yes, the two topics are closely related, which is why they should link to each other from within the first sentence (non just from the lead). Now that they do, I don't see a good reason to contravene WP:RELATED. --Giuliopp (talk) 23:42, 22 August 2012 (UTC)

I respectfully disagree, Giuliopp. I don't believe that your view on the matter is necessarily determinative for this article, and WP:RELATED is merely a Wikipedia guideline, not a formal policy. However, I'm worn out from unproductive WikiDisagreements today, and may go on a long Wikibreak. Will leave it to other editors of this page to decide if the consensus we've had here for the past two weeks that this article has been in existence—one where simple and straightforward hatnotes clarified the Talk-page-agreed-to-consensus scope of the MSL and CR articles—is better than your particular view, for this article. Cheers. N2e (talk) 03:52, 23 August 2012 (UTC)

"Keep - The statement, "There is virtually zero chance that readers googling for either Mars Science Laboratory or Curiosity rover could end up on the wrong article, as the two titles are completely different" has many problems as an argument for excluding the hatnote. 1) Hatnotes are not provided for aiding in a Google search, they are used to distinguish between similar articles in a Wikipedia search, which is not based on the same algorithm. 2) The Mars Science Laboratory article contained the Curiosity rover article until recently. Many readers who have already used the MSL article for reference may wonder why more recent information is not included. Conversely, users looking for information for the MSL spacecraft may wonder why it isn't mentioned in more detail in the Curiosity rover article. If you take a moment to view the user feedback on both pages (the link is located at the top of each talk page), people often confuse the two topics, and with good reason. 3) The mission is called the "Mars Science Laboratory mission". The Mars Science Laboratory spacecraft itself has since crashed on Mars, and won't be reporting any further data. The article Curiosity rover has been designated by community consensus as the proper article for taking over main coverage of the ground mission. This was an arbitrary decision, of which the common Wikipedia user would have no knowledge. Saving the potential reader of the article having to read the entire article, only to find out it wasn't the information they were looking for, is not the most user-friendly approach. I believe the hatnote is not only appropriate, but completely necessary in this case. OliverTwisted ^(Talk)(Stuff) 03:40, 24 August 2012 (UTC)

• Keep -Although the MSL (mission) and Curiosity (rover) are related, they are not synonyms. BatteryIncluded (talk) 04:30, 24 August 2012 (UTC)
• Keep - *Entirely* Agree With The Well-Described Reasons Noted Above - Yes, The Mars Science Laboratory And Curiosity Rover Articles Are Different But Closely Related - Hatnotes Seem To Smooth The Way (so-to-speak) imo - In Any Case - Enjoy! :) Drbogdan (talk) 12:20, 24 August 2012 (UTC)

Guys, please have a look at WP:HAT; the main question to consider is "Could a reader wrongly end up on this article, while looking for a different one (e.g. due to an ambiguous title)?" If the answer is "Chances are, yes", then a hatnote is entirely appropriate. This is not the case here: whoever searches for "Curiosity rover" or "Mars Scien..." (either through Google or WP's search engine; the result is the same) is taken straight to the intended article, no disambiguation needed. The scope of both articles (and the relation between Curiosity and MSL) is clear from reading the opening line – no need to read the entire article – again making a hatnote wholly redundant. Going by the same "Keep" logic , then for example Mercury-Redstone Launch Vehicle should have a hatnote pointing to Project Mercury and so on for countless other articles. There is already enough clutter around WP: let's try to keep it at a minimum. --Giuliopp (talk) 15:24, 24 August 2012 (UTC)

"Keep - There is specific confusion in the media and with the general public, where Mars Science Laboratory is used to talk about multiple things: the mission as a whole, the spaceflight, the spacecraft, or the actual rover operating on Mars. It may one day be the case that the Wikipedia articles may one day be renamed, but for now, per Talk-page consensus, Wikipedia is using the two terms to describe two different but related things: MSL for the spaceflight and spacecraft, and Curiosity Rover for the rover and the surface science mission. It is precisely because of this confusion by readers that the MSL and CR article page consensus had been to include the hatnotes, and it appears that is still the consensus. WP:RELATED and WP:HATNOTE are merely a Wikipedia guidelines, essays that have been written by a few editors interested in the topic; they are not a formal policy. And they need not be determinitive in a case like this, where the article-level consensus is to include clarifying hatnotes. Cheers. N2e (talk) 01:29, 26 August 2012 (UTC)

• Keep - Agree with all of the above. I've followed the mission closely, and still wasn't totally clear on the MSL/Curiosity distinction. In part, this is because general media coverage has tended to use the two interchangeably, I suspect, and this acts against the reader actually absorbing the information provided on the first line. A hatnote would draw attention more clearly, and emphasise the potential for confusion. I note the hatnote is currently absent as well? I'd strongly advocate that either the hatnote or a sentence in the article lead needs to spell out words to the effect of "This article focuses on the rover itself and the science it carries out. For details on the overall mission and its planning, see MSL." And the reverse for the MSL article. DanHobley (talk) 13:24, 27 August 2012 (UTC)

DanHobley, look back in the article history before Giuliopp's edit on approximately 22 Aug and you will see the words that were previously in the article hatnote, then do the same at the MSL article, and I think you will find a pretty good set of words to use once again. Just waiting for some editor to come along and tie up the consensus, if any, on this discussion before reinserting the words in the two articles. Or, I suppose, some editor might add the two hatnotes back in under the Wikipedia Bold-Revert-Discuss process and let the hatnotes remain in the articles while the discussion is going on. Cheers.

AfD fate for Timeline article not looking good

It would appear the fate of the Timeline article is nearing a decision, and the outlook isn't positive. We should probably have a plan for dealing with the information in the Timeline subsection of this article, once it has been deleted. Deleting the MSL timeline article link is easy. Could the graph table information be condensed? There appears to be a bit too much empty space in the "Launch, cruise and landing" section. Perhaps the information in that section could be revised slightly to present a tighter table? I don't believe anything will be added to this particular section in the future, which might deal with the empty space issue by adding data. The content deals with minor course corrections. Perhaps they could be consolidated to one line with each single correction listed: "Trajectory correction 1: Jan. 11, Trajectory correction 2: Mar. 26th, etc. There are only 4 total corrections with dates, only one of which has a note.

Expanding the "Event" column size slightly will also fix some chunks of empty space, by eliminating 3 lines of text in some of the event fields. This is assuming we keep the graph in this format. OliverTwisted ^(Talk)(Stuff) 06:06, 21 August 2012 (UTC)

I think that from an encyclopedic point of view, all that's need 'now' in the way of a time-line is a table of the major stages in the appropriate article. Eg.,

• Mission proposal
• Design, development, and testing of probe etc., including the initial planing of field-work for the Rover.
• Departure.
• Arrival.
• Software upgrade, system, hardware testing and calibration.
• Major notable discoveries and events. (After all, this is its raison d'être)
  

A linkable citation back to the comprehensive NASA time-line will provided all the minutia of detail that the really inquisitive reader will want. Too much detail here on WP, makes it a 'Dear Diary' rather than a time-line IMHO. --Aspro (talk) 12:26, 21 August 2012 (UTC)

I would support almost any other version of the information than is presently appearing on the page. It almost doubles the size of the article, and will keep growing to eclipse all else. OliverTwisted ^(Talk)(Stuff) 05:08, 22 August 2012 (UTC)

Agreed. For now, I have placed the hidden comment above the start of the table <!-- Please only add significant events to this time-line -->.Regarding the column width. I'm going to add scope="col" width= to the wiki-table to adjust the 1st column to make it just wide enough for the Wikipedia:Manual_of_Style/Dates_and_numbers#Dates formate; I.e., Sept 28, 2012. Then expand the 2nd column a little. Wrap around onto a second or third line can also be avoided by making some of the events less verbose. As the list gets longer some hard pruning will have to be performed. --Aspro (talk) 17:17, 22 August 2012 (UTC)

My intention is to wait until the main timeline article goes WP:TNT so we can do something workable there. Then, the timeline abstract in this page will be reduced to basic 4-6 entries (if any at all). Alternatively, I like the narrative style used in the Opportunity rover article, which by the way, takes about 4/5 of the total article content. My thoughts, anyway. I will go with the consensus. Cheers, BatteryIncluded (talk) 13:40, 22 August 2012 (UTC)

Yes, the narrative style makes for a better encyclopedic article. My view is that a separate and simple vertical wiki-table list for all the 'minutia' events (without images) will draw away from this article the non-notable details. So, I'd like to have new article started called (as W. D. Graham suggested Timeline of the Mars Science Laboratory mission) and just keep it boringly simple. Then there will be no excuse to have a tabular time-line here; as it's hard to justify it even now. So, I'll wait too.--Aspro (talk) 19:01, 22 August 2012 (UTC)

Per WP:BOLD, and the no consensus outcome for deletion rached at [19] I decided to WP:Blow it up and start over; I began the process of moving and re-writing the timeline in a narrative format. Please feel free to edit and expand the Timeline of the Mars Science Laboratory mission with significative events and plenty of relevant images. Cheers, BatteryIncluded (talk) 19:38, 28 August 2012 (UTC)

Design flaws

For some unknown reason, NASA permitted the MSL to have exposed wires as part of its deployed design. Mars has lightning (just like the earth does) and lightning events can damage exposed wires. Separate from this issue, it is possible for wires to be damaged by the landing process. At least one wind sensor, may have had it wires cut or damaged by the landing process.[20]

Many people involved in space segment imaging systems feel that the MSL imaging sensor was permitted to have too low a resolution for no good reason. The MSL Mastcam imaging specification was frozen in 2004, and never updated. Although the MSL has better cameras (~2 megapixel) than the previous generation of Mars rovers (~1 megepixel) this is only a 2x improvement.[21]

(This really needs to be part of the pages for this device, as these are known problems. Wikipedia should not as a rule be covering up technical and technological mistakes, as no possible good can come from doing so. Ignoring design flaws very often leads to needless loss of life (by repeating the same mistakes) later on. Eyreland (talk) 09:25, 25 August 2012 (UTC) )

You may want to adress your concerns to NASA. BatteryIncluded (talk) 13:29, 25 August 2012 (UTC)

Having exposed wires was just taking a calculated risk v. cost. No more a design flaw than failing to provide each passenger aircraft with ejector seats. Likewise, with the cameras. NASA has to make the most of the budget made available and do it's best to meet the deadlines set. See: Mars rover camera project manager explains 2MP camera choice. So it would be erroneous to allow uniformed opinion to creep into Wikipedia.--Aspro (talk) 14:51, 25 August 2012 (UTC)

Isn't this mission mostly about conducting laboratory experiments? If so, that's probably where the money went. It's not like we've never seen the surface of Mars before. ←Baseball Bugs ^{What's up, Doc?} carrots→ 16:21, 25 August 2012 (UTC)

These two separate pieces of information would seem to be something that might fall under a "criticisms" or "controversies" section. However, there would need to be a reliable source quoted in a reliable publication accusing the rover of having a design flaw, rather than speculation in the BBC article. The BBC article never mentions the phrase "design flaw", nor anything similar, and the strongest language they are willing to use is No-one can say for sure how this happened, but engineers are working on the theory that grit thrown on to the rover by the descent crane's exhaust plume cut the small wires. Unfortunately, the documented damage to the wind sensor would not seem to be mentioned at all in the Curiosity rover article, and should probably be addressed in the REMS section with what is reliably being reported.

The second topic has a similar problem. Many people involved in space segment imaging systems feel that the MSL imaging sensor was permitted to have too low a resolution for no good reason. Who are those many people? They aren't defined in the source provided (Gizmodo). Further, the author goes on to say the biggest problems with the early images were the dust caps, which have now been discarded. Next, what exactly is meant by "no good reason"? Cost cutting would be a fairly good reason, as would any number of other reasons, such as contractual agreements, weight, power drain, lens performance on Mars, etc. Further speculation is not supported by the current sources provided at this time, and inclusion would result in WP:SYNTH or WP:OR without specific coverage by more reliable sources.

Chemistry and Mineralogy (CheMin)

The above post by User:Ynhockey, refers to the fridge which is used to lower the thermal noise in the CCD on the CheMin. This cooling is required due to the very long exposures (the noise would otherwise swamp the signal). The link suggested is not IMHO very suitable and smacks of advertising. However, this complex part of the rover deserves its own article (with proper links), would Chemistry and Mineralogy (CheMin) be suitable do you think? Meaning: the title could be confused with the 'subject' of Chemistry and Mineralogy rather than a analytical instrument. Or perhaps MSL- Chemistry and Mineralogy (CheMin) --Aspro (talk) 11:42, 19 August 2012 (UTC)

IMO that note is of little use, as it describes their emotional response instead of the hardware. In addition, it does not specify in which system it is installed. There are thousands of vendors that provided hardware to the mission, this is one of them. BatteryIncluded (talk) 12:28, 19 August 2012 (UTC)

Just a note, the materials section is something I started in dozens of articles, it's basically a "sticky thread" that others are welcome to contribute to listing potentially useful sources for the article that aren't used (yet). I think it works well in general and should stay at the top—although it's true that with just one such source the usefulness may be put into question.

Regarding the matter itself: If indeed it is the case that thousands of companies supply the hardware, I don't think we should introduce undue weight by listing just one of them—although other details about the fridge would certainly make it notable, which is one of the reasons I posted here—clearly some of the editors are knowledgeable on the subject and will be able to get more information. Aspro: if you have enough accessible sources to create an article on the cooling system, I will gladly assist in writing such an article. I am not knowledgeable on the subject though.

In the long run, IMO there's no reason why we can't mention all the details of the rover, including who provided what (for non-trivial parts), even if there are thousands. —Ynhockey ^(Talk) 13:01, 20 August 2012 (UTC)

It wasn't the cooling system that I thought was notable enough to have is own article but the instrument that it is a part of, namely the Chemistry and Mineralogy (CheMin). Sorry for any confusion. I was just asking for an opinion on how such article should best be named so as not to confuse WP readers when searching, by making title appear to be about the scientific subjects of Chemistry & Mineralogy. --Aspro (talk) 13:40, 20 August 2012 (UTC)

I think a hatnote will be enough to avoid any confusion, but we can always (also) disambiguate the title like you said (Chemistry and Mineralogy (CheMin)). —Ynhockey ^(Talk) 14:17, 21 August 2012 (UTC)

Roving

As of August 29th, 2012 (today) the rover has started traveling. (http://www.jpl.nasa.gov/news/news.php?release=2012-269). 52 feet so far. Perhaps there should be a new section after "Landing" called perhaps "Roving" to track the robot's travel as it proceeds? Gatfish (talk) 23:41, 29 August 2012 (UTC)

I think that the best place to record the rover's most relevant activities will be in the Timeline of Mars Science Laboratory‎. Cheers, BatteryIncluded (talk) 02:12, 30 August 2012 (UTC)

Full sterility procedures can't get rid af all spores and extremophile bacteria. NASA knows this and that is what has to be mentioned. BatteryIncluded (talk) 12:53, 11 September 2012 (UTC)

Right but DHMR and other methods reduce the risk. The level for special regions is 0.3 spores per square meter and than you have nearly no chance to find one on the drill bit.

Reading the discussions I see that people have not the slightest clue of Planetary protection. I read that Viking already deposited microbes. Viking was backed as whole and it was cleaner than curiosity in that respect. Mrs Conley gets the blame although she is only the messenger of the news. In reality this is a small problem compared with what we will face when we have a human on Mars. They are not sterile.--Stone (talk) 12:59, 11 September 2012 (UTC)

Article split—August 2012

As of 6 August 2012, with the successful landing of the Curiosity rover on Mars, this article has been split from the Mars Science Laboratory article. This topic was discussed on the Talk:Mars Science Laboratory Talk page in the weeks leading up to the landing. The rationale was topic breadth. With the successful landing, it seemed that a new article to focus on the:

• planetary science aspects of the robotic rover surface science mission— named Curiosity rover—would be in order.

... while retaining the descriptive aspects of the

• spaceflight mission— entitled Mars Science Laboratory (the actual name of the spaceflight mission, as assigned by NASA), describing the launch, transit to Mars, the novel Entry and Descent through the Martian atmosphere and the Landing on the Martian surface (collectively, the spaceflight: launch, transit, and EDL).

Consensus was achieved to split the articles into two, immediately after the SUCCESSFUL landing of the rover. The payload of the spaceflight mission, the Curiosity rover, has now landed successfully on Mars. Time to split the article. Cheers. N2e (talk)

See notes on some summarising and moving of text from MSL article to rover article at Talk:Mars Science Laboratory#Article split—6 August 2012. Note the rover article needs a section on the robot arm. -84user (talk)

FWIW - Congratulations On The Excellent Article Split - Article Looks Great - Thanks To All For The Excellent Effort - Enjoy! :) Drbogdan (talk)

Thanks, Dr. B, I think the planning and pre-landing consensus made the article much better sooner than had we not done all that work. N2e (talk)

Mars vs. Mars' vs. Mars's: the use of possessives

There is a tendency for multiple forms of the word Mars in the possessive form being used within the article. Here is a quick refresher from the Wikipedia Manual of Style: MOS:POSS.

• Mars' equator = commonly viewed as correct

• Mars's equator = technically correct for verbal pronunciation, but less desirable in written form

• The equator of Mars (the avoidance of inanimate possessive nouns) = most desirable in both verbal and written form

While this isn't quite as important as other aspects of the article, it can be distracting to see multiple variations used. The easiest way to avoid this is to change the phrasing to the "moons of mars" rather than having differing possessive forms within the same article, and causing editors to consume time trying to decide whether it should be Mars' moons or Mars's moons.

Thanks for posting - discussion on Mars methane is presently ongoing - and seems worthy imo - Thanks again - and Enjoy! :) Drbogdan (talk) 17:43, 2 November 2012 (UTC)

Like expected from a good number of experts there is no big methane peak. --Stone (talk) 17:53, 2 November 2012 (UTC)

I wonder what is the location of the alleged methane "plumes" relative to Gale crater. BatteryIncluded (talk) 01:06, 3 November 2012 (UTC)

Interesting question - seems the Curiosity Rover is at 4.5895°S 137.4417°E / -4.5895; 137.4417 - one Methane Plume seems to be at 0°N 310°W - this *might* be about 5,100 km (3,200 mi) west of the Curiosity Rover according to my estimate using the Google Mars program; another Methane Plume seems to be at 30°N 260°W - this *might* be about 2,921 km (1,815 mi) northwest of the Curiosity Rover - not sure about this - verifications welcome of course - in any case - Enjoy! :) Drbogdan (talk) 02:04, 3 November 2012 (UTC)

Plumes of 50 ppb or more would give a higher methane level in the atmosphere. The atmosphere chemists are very confident about the half life of methane of hundreds of years not weeks what you see from the plume evolution, so .....--Stone (talk) 08:04, 3 November 2012 (UTC)

There is no argument that in situ measurements take precedence over orbiters' or Terran telescopes. Besides, even if the methane was seasonal and had a (short) life of 350 years, it would be distributed and detected all over the atmosphere. Maybe we could take a closer look at the paper(s) critical of atmospheric methane. Privately disaapointed, BatteryIncluded (talk) 20:59, 3 November 2012 (UTC)

The plumes observed in 2004 make only sense if the half life is very short. If this is the case and the 2004 event did not happen again the global levels for methane would be nearly zero. This is exactly what TLS is meassuring. So the plume event has to be investigated to get things right.--Stone (talk) 21:19, 3 November 2012 (UTC)

I agree. If the 2004 plume event was real, the methane should be there after 350 years. Maybe you can update the methane section at Atmosphere of Mars? Cheers, BatteryIncluded (talk) 21:33, 3 November 2012 (UTC)

Perhaps unlikely - (and I'm not clear about this at the moment) - but since methane-consuming microbes (Methanotrophs?) seem to exist, *perhaps* they're (at least partially?) an explanation for any rapidly disappearing methane? - Enjoy! :) Drbogdan (talk) 22:03, 3 November 2012 (UTC)

Kevin Zahnle has been arguing for a while that there's a pretty robust case to be made that the remotely sensed data showing methane on Mars is flawed. You can read the paper for free here. I heard him talk on this earlier this year, and was pretty convinced. I'd say the current readings from Curiosity should probably (and sadly) be read to indicate that there just aren't any substantial methane sources on modern Mars; i.e., this should be the null hypothesis even having seen the remote sensed data. That's not to say they shouldn't keep looking, but I'm pretty doubtful they're going to find anything. Shame. DanHobley (talk) 00:47, 4 November 2012 (UTC)

Timeline overload

The Timeline of Mars Science Laboratory article is now referenced in 3 highly visible places: the hatnote, in a section which is empty except for the intralink to the article, as well as in the "See also" section. This would seem to be the consequence of the extended debate over the format of the Timeline article, when links to that article were installed during edit wars. I question whether it is necessary in the hatnote? I also question having a section where the only content is a link to another article, especially when that content is located in the hatnote at the beginning of the article, as well as the See also section.

My recommendation would be to remove the hatnote containing the timeline, as well as the nearly empty section with the intralink. A "main article" link would seem to be more appropriate, could be installed in any one of multiple relevant sections (ex: landing section), and will help avoid the cluster of videos, images and the nearly empty text section at the bottom of the article, leading into the multimedia sections. Just a suggestion. Cheers. --OliverTwisted ^(Talk)(Stuff) 01:05, 9 October 2012 (UTC)

I deleted the Timeline subsection, but I think that the hatnote and the 'See also' section links are quite useful for updates. Cheers, BatteryIncluded (talk) 21:12, 3 November 2012 (UTC)

I've been hands-off lately, leaving it to the experts. I do have one suggestion though. If you have a smartphone, you might want to check out this article on the mobile Wikipedia site. Of particular note, the images collected in the "image" section in the article on the mobile site are different from the images viewed on the standard Wikipedia article page in the way they are displayed, and some of this is beyond control. However, some of the images are not able to be viewed fully on the mobile site on a 5" or 7" screen, due to their alignment and/or formatting. I'm not enough of an expert on image placement, or the mobile site mark-up itself, that I can specifically state what might be changed, but if you view it for yourself, you'll see what I'm seeing. Also, the timeline overload no longer appears to be an issue. Great work, as usual. OliverTwisted ^(Talk)(Stuff) 07:27, 21 November 2012 (UTC)

Planning the daily missions for Curiosity on Mars

There is a lot of good (reliable source) information on how the daily "missions" for Curiosity are planned for each Martian day (sol), how many scientists and engineers are involved, etc. in this article published today [24]. It covers the planning teams switch back to Earth time, but has much more that could be gleaned, and might make for the start of a new section in the article. Cheers. N2e (talk) 14:33, 8 November 2012 (UTC)

Yes it can be useful and interesting. There are several articles on it, but I would caution against creating a long-winded and detailed section. In my opinion, we should limit it to the highlights, such as the daily overnight planning. Cheers, BatteryIncluded (talk) 16:30, 9 November 2012 (UTC)

Concur, completely. Short, brief descriptive statement or two about the overnight process, number of people working it, etc. Would be good to find out the full time equivalent employment to keep the venture running at JPL, totally separate from the number of scientists who are using the data.

Marching band

NASA (via an NPR interview) reports today (Tuesday, November 20, 2012) that the Curiosity Rover, apparently based on a SAM analysis, has made "an 'earthshaking' discovery" - according to John Grotzinger (MSL Principal Investigator), “This data is gonna be one for the history books. It’s looking really good.” - but the Curiosity scientists want to verify their results before making an official announcement - maybe in a few weeks? - Enjoy! :) Drbogdan (talk) 16:52, 20 November 2012 (UTC)

BatteryIncluded you seem right, the SAm instrument is mentioned and this instrument is good for organics and methane. Methane is already out of the race. --Stone (talk) 22:24, 20 November 2012 (UTC)

• You and user DanHobley are correct, as measurable δ13C is an intended jack-pot to the SAM instrument. Without speculating any further, before the Curiosity landed, there has been a strong indication that methane is a seasonal occurrence, so I consider methane is still on the race. The SAM instrument is just waking up, and it still has a long journey of possibilities of calibration and sampling for narrow detection ranges. Besides, carbon isotope ratios in CO₂ can also distinguish between their geochemical or biological origin. BatteryIncluded (talk) 04:07, 21 November 2012 (UTC)

The scientist have real strict rules of the road not to comunicate anything to the public befor it was ofically allowed. Has Grotzinger violated this? --Stone (talk) 22:29, 20 November 2012 (UTC)

I don't think he violated their NASA rule. NASA is so desperate for planetary science funding that only public enthusiasm can help them. Anticipation of imminent good news may be good PR strategy. Although the last time they used a "marching band" as news release, they got shot down by their own hyped research and twist on the GFAJ-1 microbe. PS: I heard through a very reliable NASA source that they have confirmed that Earth is 6,000 years old. ;P BatteryIncluded (talk) 23:54, 20 November 2012 (UTC)

It doesn't matter too much whether Grotzinger broke a rule, as far as Wikipedia is concerned, because once he'd announced it, everyone would know anyhow, and it would be silly to pretend we didn't. The information in this situation is withheld as a matter of scientific courtesy, not military secrecy or national security.

Listening to the last JPL videoconference from a few days ago, I was thinking over with some amusement questions from newshounds who wanted to know when Curiosity was going to get on with driving to the center mountain, and whether anything really important had been discovered. I started counting ... it's only been a few weeks into its mission, much of that checking equipment, and they've already discovered some quite interesting things. Leptus Froggi (talk) 04:30, 21 November 2012 (UTC)

For us it is of no concern where we got the info from. As a journalist I would try to get the fullstory before the others. Have fun Mr Grotzinger you have a bunch of journalists and a bunch of idiots following you around!

That video you mentioned is very useful as he hinted that the "discovery" is NOT related to methane, but to the soil. If organic molecules are present in the soil, a significant fallout will ensure, because the Viking landers found none (not sensitive enough) and so NASA nulified its LR positive results indicating active (current) metabolism (current life).

The three SAM instruments are the TLS, QMS and GC. Of the 3, only the GC relies on heating the sample, so perchlorate may nulify its relult. Still, 2 positives out of three methods would be great to help understand the surface chemistry. Any way, we could expect a short lived flurry of editions quoting hyped media reports, so we may have to keep those in perspective and maybe even tone it down. We'll see.
