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.

Dead link [edit]

The ref with this url has a dead lnk: http://mpfwww.jpl.nasa.gov/mgs/newsroom/20050920a.html -- FutureTrillionaire (talk) 05:35, 8 January 2013 (UTC)

I can't find it. What ref is it currently (or what text does it follow)? Rivertorch (talk) 08:10, 8 January 2013 (UTC)
I found it, "Orbiter's Long Life Helps Scientists Track Changes on Mars", currently ref 22. This should be the updated link, but I find it rather vague to state that the southern ice cap "have been receding" based on a source which claims that CO2 deposites near the south pole was receding for a period of three years (which is now appr ten years ago). Njaelkies Lea (d) 11:11, 8 January 2013 (UTC)
Don't have refs to hand, but the gist of this is that a lot of the southern polar terrains have features (e.g., scarps, scallops, swiss cheese terrains) which are consistent with sustained loss of ices (can't recall whether CO2 or water - think water) from the southern polar region. They've documented changes using satellite repeat imagery too. It's thought this reflects gradual movement of ice from the south to the north poles, as I recall. On a year to year timescale, and looking at the actual CO2 cover, this is a bit more dubious though... as trying to argue for secular change on Earth from three photos of year-on-year snowlines would be. Refs to support the arguments from geomorphology can be found in the last few years of the NASA LPSC conference. I'll also see if I can find something more robust in Carr's Surface of Mars, I'm sure it's there. DanHobley (talk) 14:26, 8 January 2013 (UTC)
OK, on review, this sentence was actively misleading where it was. I hadn't realized it was up in the intro! I've just removed the whole sentence, along with the reference. I'll add a sentence or two somewhere lower down clarifying long term secular variations in ice cap cover, with decent reference. DanHobley (talk) 15:20, 8 January 2013 (UTC)
Sounds good! Njaelkies Lea (d) 15:36, 8 January 2013 (UTC)

What? No mention of evolution's co-discoverer Alfred Wallace's 1907 book-length debunking of Lowell's "canals"? [edit]

The title: Is Mars Habitable? Good details in our article on Wallace. --96.233.82.149 (talk) 08:04, 12 March 2013 (UTC)

Olympus Mons [edit]

The main article, under the volcanoes section, says that Olympus Mons is the second highest volcano in the solar system, but the accompanying photograph has a caption saying it is the highest. Can we get a definitive clarification? Dezaxa (talk) 22:57, 15 April 2013 (UTC)
