EPSC 2021: Scientists Use Seasons to Find Water for Future Mars Astronauts

Green (red) represents increase (decrease) in hydrogen content. The areas highlighted in orange are Hellas Planitia in the southern hemisphere, and Utopia Rupes in the northern hemisphere. These are the only extended regions undergoing a significant variation throughout the Martian year. (Credit: G. Martínez)

STRASBOURG, France (Europlanet Society PR) — An international team of researchers has used seasonal variations to identify likely sub-surface deposits of water ice in the temperate regions of Mars where it would be easiest for future human explorers to survive. The results are being presented this week by Dr Germán Martínez at the European Planetary Science Conference (EPSC) 2021.
