COLUMBIA, Md. and HOUSTON, May 16, 2022 (Universities Space Research Association PR) — A team of scientists, including Dr. Germán Martínez from the Universities Space Research Association, just published a study in the Proceedings of the National Academy of Sciences. This study indicates there are seasonal energy imbalances in the amount of solar energy absorbed and released by Mars which is a likely cause of dust storms and could play an important role in understanding the climate and atmosphere of the red planet.

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

Global map of Mars with overlaid topography indicating areas with significant seasonal variations in hydrogen content during northern spring (top) and fall (bottom). 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.
