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.
