HiRISE: Irregular crater intersecting graben in Tractus Albus
This crater, of which only a small portion is visible in the full HiRISE image, is very irregularly shaped and might suggest that some underlying liquid was present that made it so elongated after the initial impact. Another reason for … Continue reading

THEMIS: Acheron Catena
THEMIS Image of the Day, March 26, 2014. This VIS image shows several of the graben (fault bounded depression) that are part of Acheron Catena. Most of the lava flows in the image originated at Alba Mons and predate the … Continue reading

HRSC: Daedalia Planum closeup
Close-up view of the two dominant lava flows that reach the foot of the highland terrain (seen at the top of the image in this orientation). The older of the two eruptions produced the smooth lava surface to the south … Continue reading

Watch for falling rocks
A new investigation of Cerberus Fossae using HiRISE images shows that Mars is probably seismically active now or in the recent past. The clues are tracks left by boulders as they rolled downhill. Gerald Roberts (University of London) and colleagues … Continue reading
