HiRISE: Geyser season
Springtime in the South Polar region of Mars is a season of exciting activity. The thick coating of carbon dioxide ice that accumulated over the winter begins to sublimate (turn to vapor) as the sun rises higher in the sky … Continue reading

HiRISE: Thousands of spiders on Mars
As part of the Planet Four citizen science effort, volunteers searched Context Camera images for possible new locations on Mars with “spiders,” or features with radial troughs from which fans emanate in the springtime. We planned this HiRISE image over … Continue reading

HiRISE: Rectangles with wiggly sides
Ground that has a lot of water ice mixed with dirt tends to crack in polygonal patterns bounded by short straight channels. In the South Polar region of Mars this type of terrain may be covered by a seasonal polar … Continue reading
