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 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.


Silica Discovery[edit]

Much higher concentration of silica element at some sites over the past last seven months than anywhere else in the last 40 months after landing and silica makes nine tenths of composition of some of the rocks. The high silica was a surprise, the scientist said. And it supports microbal life.

Irrelevant reference[edit]

Reference 24 doesn't say anything about atmospheric pressure on Mars being "6/1000 of Earth's". Someone with edit rights, please do something about it! IlnarSelimcan (talk) 20:25, 22 July 2017 (UTC)

Where does it say 6/1000 in the article? I don't see it. RivertorchFIREWATER 04:15, 23 July 2017 (UTC)
It's in the 3rd paragraph of the lead, styled as 61000. I removed ref. 24 which is redundant. The source might be in "Heldmann, Jennifer L.; et al" (currently ref. 25) which I don't have access to.
IlnarSelimcan, if you have a specific edit in mind, please feel free to make an edit request on this Talk page. WP:Edit requests explains how to do it. Dlthewave (talk) 12:29, 23 July 2017 (UTC)

Semi-protected edit request on 26 July 2017[edit]

In the second paragraph it states: "The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons." In fact, it is not Mars' tilt that is primarily responsible for creating its seasons. Rather, it's the eccentricity of its orbit (the fact that it moves closer and further from the sun at various times throughout its year) that is primarily responsible for producing its seasons. I might change the current sentence to: "The rotational period and seasonal cycles of Mars are likewise similar to those of Earth. Though its rotational axis is tilted with respect to its orbital plane a similar amount as Earth's, unlike Earth its seasons are primarily caused by its elliptical orbit."

Not done: please provide reliable sources that support the change you want to be made. jd22292 (Jalen D. Folf) (talk) 21:09, 26 July 2017 (UTC)
