(Albuquerque, NM) -- The rims of large impact craters on Mars are even more unusual than we thought. In recent research published in the prestigious scientific journal “Geology,”* lead author Larry Crumpler, planetary geologist and research curator at the New Mexico Museum of Natural History and Science, and other team members on NASA’s Mars Rover Opportunity Mission describe unexpected geologic features encountered on the rim of the 22 kilometer (13 miles)-diameter impact crater Endeavour. Observations along Opportunity’s traverse showed that while pre-existing rocks at Endeavour crater were shoved upward and tilt outward like those seen in small craters like the Barringer (Meteor) Crater on Earth, in an unexpected twist, at Endeavour crater they also arch over at the rim and tilt inward.

“Opportunity had been traversing on Mars for over 45 kilometers (28 miles) over its 14.5 year lifetime and there have been many “firsts... Read More...
