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

Please update to reflect the success of India lower down the article in the Exploration section as the one of the countries to have sent a mission and also the first Asian country and the first to achieve orbit on first mission - you have identified the satellite in the initial paragraphs but not in the exploration body where the additional detail might best be inserted.

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 :

Change min-max surface temperature. Min is -153 °C and the max is 20 °C according to NASA. Source: (talk) 01:41, 12 January 2009 (UTC)

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)

"Aluminum" really? Step it up America.

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. [1]

Mars gravity vs. Mercury gravity[edit]

The gravity of mars is defined as the same as mercury. How is it defined for Saturn, on Sunday the same as mars? That's not a definition — Preceding unsigned comment added by 2602:302:D8C:D9:8CC3:4044:7010:FA37 (talk) 18:49, 6 July 2015 (UTC)

It seems that Mars is more massive than Mercury, but Mercury is smaller and denser. By chance, they end up having almost equal surface gravity, which is kind of cool. The surface gravity statistic in both articles is supported by a source. A2soup (talk) 19:04, 6 July 2015 (UTC)
The equality of gravity for Mercury and Mars came from the third and fourth sentences in the "Physical characteristics" section. In the Infobox, that area outlined with a rectangle in the upper right hand corner of the article, there is the gravity of Mars listed as 3.711 m/s. I hope this helps. - Fartherred (talk) 19:35, 6 July 2015 (UTC)

NASA-TV/ustream (9/28/2015@11:30am/et/usa) - Mars Mystery Solved.[edit]

NASA-TV/ustream (Monday, September 28, 2015@11:30am/et/usa) - NASA will detail a "Major Science Finding" about the planet Mars[1] - Enjoy! :) Drbogdan (talk) 00:52, 25 September 2015 (UTC)

BRIEF Followup - evidence presented that liquid water may be currently flowing on the planet Mars[2][3][4] (conference videos[5][6] and somewhat related Nature (journal) (1979) reference re lifeforms in the hypersaline (and/or brine) water of Don Juan Pond, Antarctica[7]) - in any case - Enjoy! :) Drbogdan (talk) 18:16, 28 September 2015 (UTC)
Pouring cement, honey, molasses, brine, etc. have some water, yet are not water. The flow of brine is not flow of water. It has a water feature, yes, but for habitability/colonization purposes, solid water ice is superbly preferred to brine. Cheers, BatteryIncluded (talk) 18:24, 28 September 2015 (UTC)

Mars water discovery[edit]

Hello, It is commonly known that evidence of seasonal waterflow or active waterflow was found on Mars near the Curiosity[1], but the curiosity is not allowed to look[2]. Please try to edit this in to the article.

Thank you.
