Geological evidence of a planet‐wide groundwater system on Mars
[Ed. note: Earlier reports about this research here and here.] Planetary Geomorphology Image of the Month, July 1, 2019: Francesco Salese (Utrecht University). Groundwater had a greater role in shaping the Martian surface and may have sheltered primitive life forms … Continue reading
Do ice-squeezed aquifers cause marsquakes?
As the Mars InSight lander begins listening to the interior of Mars, some scientists are already proposing that some marsquakes could be signals of groundwater beneath the frozen surface of the Red Planet. The idea, proposed by Michael Manga, a … Continue reading

THEMIS: Faulting in Labeatis Fossae
THEMIS Image of the Day, June 7, 2019. The linear depressions in this VIS image were created by tectonic forces. The sides of the depression are faults. Paired faults will allow the block of material between them to “slide down” … Continue reading

Groundwater origin for recurring slope lineae?
In mid-2018, researchers supported by the Italian Space Agency detected the presence of a deep-water lake on Mars under its south polar ice caps. [Ed. note: previously reported here.] Now researchers at the USC Arid Climate and Water Research Center … Continue reading

Mapping potential sources of Mars water
Missions carrying humans to Mars will require on-site resources, and a project led by Planetary Science Institute (PSI) scientists Nathaniel Putzig and Gareth Morgan is mapping the availability of potential shallow water-ice sources across the surface of the Red Planet. … Continue reading

Mars Express: Geological evidence of a global groundwater system
[Ed. note: This research was reported earlier here.] Mars Express has revealed the first geological evidence of a system of ancient interconnected lakes that once lay deep beneath the Red Planet’s surface, five of which may contain minerals crucial to … Continue reading
