THEMIS image: Dust devil tracks in Utopia
THEMIS Image of the Day, February 11, 2014. The dark markings in this VIS image are tracks made by the passage of “dust devils”. Dust devils are common in the extensive plains of the northern latitudes. This image is located … Continue reading

HiRISE image: spectacular new impact crater
Context Camera (CTX) images showed a likely new impact crater formed at this location between July 2010 and May 2012, and now a HiRISE image provides details about this recent impact event. Our image shows a large, rayed blast zone … Continue reading

Pressure-release melting put rocky floors into early Mars craters
Martian craters in the highlands that are wider than 10 kilometers (6 miles) often have flat, smooth, shallow floors. This fact has been noted since the first spacecraft images of Mars were taken by NASA’s Mariner 4 in 1965. Over … Continue reading

Gale Crater’s Lake District
Mars rover Curiosity landed on, or just beyond, the far end of an alluvial fan — rocks, gravel, and sand washed down by the Peace River from the north rim of Gale Crater. The rover has driven for 200 sols … Continue reading

Developing a stratigraphic column for Gale Crater’s floor
After more than 100 sols (Martian days) in Gale Crater, NASA’s Curiosity rover has driven some 500 meters (1,600 feet), traversing several rock units. A sketch of the crater floor’s geological history is emerging. On its half-kilometer drive from its … Continue reading

Grooving on Phobos
Phobos, the larger moon of Mars, has a surface covered in craters, dust, boulders – and a great many semi-parallel and intersecting grooves. One theory for the grooves’ origin, proposed in 2011, holds that they are impact scars from chains … Continue reading
How old is Meridiani Planum?
The smooth, flat plain where Mars rover Opportunity landed in January 2004 looks spookily empty. Only a few rocks and meteorites, plus foot-high sand dunes and ripples, break the endless vista under a clear tawny sky. How long has the … Continue reading
