HiRISE: Ridge in Hesperia Planum
A ridge in Hesperia Planum. Our objective is to look for fault offsets to see if these thrusts are surface breaking or not. Hesperia Planum is a broad lava plain in the southern highlands of Mars. The plain is notable … Continue reading

Many bedrock plains are clastic rocks, not lavas
The Martian surface is dominated by loose dust, sands, and rocks, but high spatial resolution imaging has permitted the detection of numerous flat-lying exposures of ancient, intact bedrock. These “bedrock plains” have previously been interpreted as lava sequences, perhaps similar … Continue reading

Two billion years’ volcanism recorded from a single Mars meteorite ejection site
Analysis of a Martian meteorite found in Africa in 2012 has uncovered evidence of at least 2 billion years of volcanic activity on Mars. This confirms that some of the longest-lived volcanoes in the solar system may be found on … Continue reading
