HiRISE: Unlocking an impact crater’s clues
Mars is a dynamic planet. HiRISE has witnessed many surface changes over the past ten years, including hundreds of new craters formed by ongoing impacts. Most of these impacts are likely caused by asteroids that have strayed into collision courses … Continue reading

Anomalous Phobos grooves caused by impacts
Some of the mysterious grooves on the surface of Mars’ moon Phobos are the result of debris ejected by impacts eventually falling back onto the surface to form linear chains of craters, according to a new study. One set of … Continue reading
THEMIS: Crater gullies in Tempe Fossae
THEMIS Image of the Day, August 10, 2016. Today’s VIS image shows parts of two craters located at the southern end of Tempe Fossae. There are numerous gullies dissecting the inner rim of the crater at the top of the … Continue reading
