Does there exist a list of all the evidence of water on Mars, listed by spacecraft?
Ideally, it would be a list with a short description and a link to a story or news release. For example: Mars Global Surveyor: NASA Images Suggest Water Still Flows in Brief Spurts on Mars http://www.nasa.gov/mission_pages/mars/new...s-20061206.html Phoenix: NASA Spacecraft Confirms Martian Water, Mission Extended http://www.nasa.gov/mission_pages/phoenix/...x-20080731.html Opportunity: NASA Mars Rover Finds Mineral Vein Deposited by Water http://www.nasa.gov/mission_pages/mer/news/mer20111207.html I know I could spend some time and extend the list that I've started above, but if someone or some organization has already done it I'd hate to reinvent the wheel! Thank you. |

This is in accord with modeled changes in the obliquity of Mars as below, resulting in cyclical sublimation and deposition of the ice caps. At higher obliquities the poles receive greater insolation and the CO2/water vapor content of the atmosphere increases. The increased greenhouse effect would cause a degree of warming with higher pressure and humidity resulting in deposition of water ice in the cooler, lower latitudes. I assume the 1.4 to 0.4 million year timescale for the features imaged by Zhurong is based on the last modeled obliquity sequence which indicates 7 or 8 cycles.
