edit·history·watch·refresh Stock post message.svg To-do list for Mars:

Please update highest temperature on Mars. While the conservative figures quoted are from Nasa, there are other Nasa sites especialy rover site which quotes much higher numbers. Would somebody please further research and update. A quote from nasa rover source at : http://marsrover.nasa.gov/spotlight/20070612.html

Change min-max surface temperature. Min is -153 °C and the max is 20 °C according to NASA. Source: http://quest.nasa.gov/aero/planetary/mars.html

Any chance that Fahrenheit temps could also be included on right hand chart??

Incorrect conversion of summer max temps in S. Hemisphere : 30C <--> 54F which is correct?

Both are correct. This is a temperature DIFFERENCE, not an absolute temperature. Boardhead (talk) 16:25, 30 September 2011 (UTC)


There's not much point in including "mean anomaly" in the chart on the right. This quantity describes the position of Mars around its orbit and changes continuously. It would be rather neat if that entry linked to an ephemeris and kept us updated on the current position of Mars.


"Aluminum" really? Step it up America.


Shouldn't the diameters of Phobos and Deimos be displayed in km (metric units)? They are now displayed as miles (imperial units). VictordeHollander (talk) 13:47, 26 February 2014 (UTC) I also noticed that the diameters of Phobos and Deimos are not in metric units. This is inconsistent with most if not all planetary data found on Wikipedia. I agree that these units should be in Km, as the metric system is internationally preferred, especially in this context.

In the news (a seven-yr event)[edit]

Mars will be the closest to Earth tonight. Expect more coverage.

Headine-1: Look up! Mars expected to light up night sky

QUOTE: “'The planet is expected to line up with Earth and the Sun. It happens every two years. You should be able to get a good look tonight.'” [The WP article herein has a great graphic on planet revolutions.] — Charles Edwin Shipp (talk) 23:46, 8 April 2014 (UTC)

Headine-2: Watch Mars Invade Our Sky: Biggest and Brightest Since 2007

QUOTE: “While this occurs every 26 months, this year’s event creates the perfect cosmic alignment to have Mars shine its biggest and brightest in the evening sky in nearly seven years.” [Take your home telescope outside tonight and watch the east.] — Charles Edwin Shipp (talk) 23:49, 8 April 2014 (UTC)

Headine-3: The Night of the Red Planet

QUOTE: “Mars, the red planet, will be at opposition on 8 April 2014. That very same night, we will explore that inspiring and amazing world thanks to the Virtual Telescope, sharing its images online, in real-time.

Live commentary by Dr. Gianluca Masi, astrophysicist.” [These people broadcast for those without telescopes.] — Charles Edwin Shipp (talk) 23:52, 8 April 2014 (UTC)

Are you suggesting something go in the article? An opposition isn't particularly special to go in the article. Otherwise, this isn't a forum to remind people of it. Scarlettail (talk) 23:59, 8 April 2014 (UTC)

Yes, something can go in the Mars article here for a seven-year event. I'm a new visitor here, so I'm putting all the news here for more regular editors here to evaluate, now or later. Also, in case you are really interested, watch the eastern horizon this evening, (about now on the West Coast.) — Charles Edwin Shipp (talk) 01:32, 9 April 2014 (UTC)

Headine-4: Awesome alignment: Mars, Earth, sun to line up (video)

QUOTE: “This means Mars rises near sunset and remains visible all night long as it moves nearly overhead across the night sky. It will be a bright burnt orange color, NASA's Mars Exploration Program reports, and almost 10 times brighter than the brightest stars in the sky.” [Hope you can watch it.] — Charles Edwin Shipp (talk) 01:34, 9 April 2014 (UTC)

The article can mention the seven year cycle, as I'm sure it already does, but there's no need for this particular one to receive special attention. Scarlettail (talk) 01:39, 9 April 2014 (UTC)
Scarlett, I see what you are saying—I'd like to hear from the other editors here (there are 935 watching, 837 have edited, and five WP editors have edited 'recently'). There are a number of sections to consider adding to or modifying. When you do a Google search of [Mars 4-8-2014] there are 7million hits, even from International Business Times. I'm not saying how information should be added (maybe with a video in external links) and that is why I am adding interesting current news. — Charles Edwin Shipp (talk) 11:32, 9 April 2014 (UTC)

Headine-5: Close Mars, Lunar Eclipse And Lyrid Meteors - April 2014 Skywatching Video

QUOTE: “Red Mars' close encounter with Earth, a 'red moon' total lunar eclipse (visible from North America) and the Lyrid meteor shower will highlight the month of April 2014. Also, the mornings and evenings will showcase Jupiter, Saturn and Venus. Credit: Space Telescope Science Institute, Office of Public Outreach” [The 'Mars' article here in Wikipedia has a 'video' section at the bottom. How current is it? How important are the entires?] — Charles Edwin Shipp (talk) 11:42, 9 April 2014 (UTC)

Headine-6: Astronomical Events 2014: Watch the ‘Biggest’ and the ‘Brightest’ Mars on April 8 and April 14; When and Where to View it Live

QUOTE: “On April 14, 2014, Mars and Earth will come close. Sky gazers can enjoy the night by witnessing two celestial events. On this night, Mars can be viewed its "biggest in more than six years." But the event concurs with the rare celestial event, the total lunar eclipse. Moon and Mars will be "blazing red in the night sky," as described by the Web site. ” — Charles Edwin Shipp (talk) 11:52, 9 April 2014 (UTC)

  • "Crickets" -- I'm moving over to the Moon for the eclipse Monday 4/14/2014 11pm-midnight Los Angeles time. [1] -- Charles Edwin Shipp (talk) 20:15, 12 April 2014 (UTC)

NOTE: The quotes added here in TALK are to improve the article, now or later in the year, especially with new video and discovery. — Charles Edwin Shipp (talk) 14:49, 15 April 2014 (UTC)

Discovery? What discovery? This article is not about Mars news headlines, nor is Wikiepedia a news website.  — TimL • talk 17:04, 15 April 2014 (UTC)

That's why I am putting this information here in TALK. I'm move over to Mars Rover. Charles Edwin Shipp (talk) 15:11, 10 May 2014 (UTC)

The 47-year cycle of Mars was observed by the Ancients[edit]

The 47-year cycle of Mars: after 47 years - 22 synodic periods of 780 days each - Mars returns to the same position among the stars and is in the same relationship to the Earth and Sun. The ancient Mesopotamians discovered this cycle. [2]

Semi-protected edit request on 9 May 2014[edit]

1. Please add "5.1 Mars-One mission" in content between "5.Exploration Missions and 6. Astronomy on Mars" 2. Please add "Mars One is a not-for-profit foundation that was founded by Bas Lansdorp & Arno Wielders (both from Netherlands) and that aims to establish a permanent human settlement on Mars. Mars One will select and train the human crew for permanent settlement. Departure of crew will start from year 2024" in 5.1 Mars-One mission Kg.iitb (talk) 15:12, 9 May 2014 (UTC)

Do you have a source to prove the notability and significance of this mission and why it needs its own section? Scarlettail (talk) 15:30, 9 May 2014 (UTC)

Mars One[edit]

Regarding the above edit requests, it seems the Mars One has plenty of sources establishing notability. Now the question is, what, if anything, should be addeded about Mars One to this featured article? --NeilN talk to me 04:26, 10 May 2014 (UTC)

I think it may be too early to consider adding content about that proposed mission. We should hold off until their process comes closer to becoming a reality. Dawnseeker2000 04:35, 10 May 2014 (UTC)
I think conceptualization of a mission of such futuristic vision in itself is an event when mankind has not travelled beyond moon till date. Even if the project fails its importance will lie in the fact that such thing was atleast attempted sincerely once. A short note would be a good value addition to an already excellent page(Kg.iitb (talk) 05:19, 10 May 2014 (UTC))
So far absolutely nothing has been attempted and for all anyone knows it is an elaborate hoax.  — TimL • talk 05:59, 10 May 2014 (UTC)
I agree that it's too early. The mission should prove its abilities first, as it's obviously quite ambitious. It needs to become tangible rather than just a proposal. Scarlettail (talk) 05:55, 10 May 2014 (UTC)
Most of the sources are from the Mars One website, Facebook and Twitter feed, that whole article is a farce. It should be a tenth as long if that, because all Mars One is right now is a public relations (marketing) campaign.  — TimL • talk 05:59, 10 May 2014 (UTC)

'Closest approaches' section - deletion of 2003 internet rumor[edit]

I have deleted the following as unneeded and unencyclopedic: An email sent during the close approach in 2003 has, in succeeding years, repeatedly spawned hoax emails saying that Mars will look as big as the Moon. Jusdafax 22:52, 21 June 2014 (UTC)

inaccurate distances[edit]

I'm creating a page on the orbit of Mars. The perihelion and aphelion distances are 1.3814 and 1.6660 au, agreeing on a solex table of distances, VSOP87 elements, the 250 year best fit by E. Myles Standish, and F. E. Ross from at least a century ago. But Wikipedia doesn't agree with either in the last digit. Saros136 (talk) 04:03, 25 July 2014 (UTC)
