The Landslide Will Bring It Down (On Mars)

Posted By on Mon, Jul 25, 2011 at 1:30 PM

Well, I've been afraid of changes, cause I built my life around you... This week's picture of Mars, courtesy of the UA Lunar and Planetary Lab's HiRISE camera aboard the Mars Reconnaissance Orbiter, highlights the Landslides in Valles Marineris.

Valles Marineris is the largest canyon in the Solar System: if superposed on a map of the United States, it would stretch all the way from Los Angeles to Washington, D.C., possibly even up to New England! So this image is just a very small portion of the system.

This observation shows us gully-like landslides (called "mass wasting") on the interior layered deposits of Valles Marineris. These include alcoves and channels, which are also visible in PSP_004396_1675. However, that image quality was very poor due to a dust storm, so a re-image can give us fine-scale shapes and sizes.

This caption is based on the original science rationale.

The pic makes me long for a little Stevie Nicks:
