HiRISE: Crater on a crater wall
It’s not that common to see craters on steep hills, partly because rocks falling downhill can quickly erase such craters. Here, however, a small impact occurred on the sloping wall of a larger crater and is well-preserved. Dark, blocky ejecta … Continue reading

THEMIS: Triple strike on Solis Planum
THEMIS image of the Day, June 6, 2017. Today’s VIS image is of a group of craters in Solis Planum. Because three of the craters are overlapping it is possible to determine the order in which those three were created. … Continue reading

THEMIS: Aonia Terra crater ejecta in false color
THEMIS Image of the Day, April 26, 2017. Today’s false color image shows several small craters in Aonia Terra. The false colors help show differences in the patterns of debris ejected in the impacts. The THEMIS VIS camera contains 5 … Continue reading

HiRISE: Is that an impact crater?
This image was acquired to take a closer look at a circular feature that might be an impact structure on the South Polar layered deposits. Measuring the sizes and frequency of impact craters provides a constraint on the age of … Continue reading

HiRISE: Plains south of Valles Marineris
This enhanced-color sample reveals the incredible diversity of landforms on some Martian plains that appear bland and uniform at larger scales. Here we see layers, small channels suggesting water flow, craters, and indurated sand dunes. [More at link]

THEMIS: Arabia Terra crater in false color
THEMIS Image of the Day, March 21, 2017. Today’s false color image shows the floor of an unnamed crater in Arabia Terra. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways … Continue reading

HiRISE: Crater with exposed layers
On Earth, geologists can dig holes and pull up core samples to find out what lies beneath the surface. On Mars, geologists cannot dig holes very easily themselves, but a process has been occurring for billions of years that has … Continue reading

HiRISE: Raised bedrock in Terra Cimmeria
Large impact craters have central hills or mountains, because the tremendous shock waves from the impact first compresses the ground, then causes a rebound when it becomes uncompressed. This effectively raises bedrock that was once deeply buried to the surface. … Continue reading
