Light-Toned Layered Deposits The SHARAD instrument on MRO has identified a thick unit of material here most likely associated with the light toned layered deposits at the rim of Valles Marineris, especially near Ius Chasmata. This location may be an ideal one for determining the thickness of the deposits and characterizing the properties of this material.
Layers in a Crater The objective of this observation is to examine layers that are exposed on the floor of an eroded crater in southwestern Arabia Terra. The layers are visible in mesas and buttes and form regular patterns in light-toned material. This image will help give us a better understanding of the geological history of the region.
Monitoring an Impact Site What appeared as a dark spot in a Context Camera image was later confirmed by a HiRISE picture in 2014 to be a new impact crater. It likely formed between March and November 2008. This image, at full resolution, is a repeat to detect any changes that, while small, could be more apparent in enhanced color.
