Curious Mars

Mars: May 2021

The ion escape of Mars' CO2 atmosphere caused by its dissociation products C and O atoms is simulated from present time to ≈4.1 billion years ago (Ga) by numerical models of the upper atmosphere and its interaction with the solar wind.

A NASA team has found that organic salts are likely present on Mars. Like shards of ancient pottery, these salts are the chemical remnants of organic compounds, such as those previously detected by NASA's Curiosity rover.

Martian subsurface habitability and astrobiology can be evaluated via a lava tube cave, without drilling. MACIE addresses two key goals of the Decadal Survey (2013-2022) and three MEPAG goals.

Evidence of recent volcanic activity on Mars shows that eruptions could have taken place within the past 50,000 years, a paper by Planetary Science Institute Research Scientist David Horvath says.
