This observation shows the bedrock on the floor of a crater near Noachis Terra. This crater is unique because it has been very well characterized as being olivine rich.
Why does HiRISE take so many repeat images of the same area? Repeat coverage actually serves a special…
Nighttime and daytime infrared images from THEMIS suggest a consolidated deposit in the floor of this ancient crater in Terra Sabaea, potentially with some bedrock exposure.
The objective of this observation was to examine the edge of impact ejecta from a crater to the north-west of this area (north is up, west is to the left).
Dusty regions on Mars are often considered to look boring in HiRISE images because the dust obscures surface features.
The sedimentary history of Mars is important to understanding climate change and the evolution of Mars.
This image covers a portion of a typical impact crater in Terra Sirenum at about 40 degrees south latitude on Mars.
The objective of this observation is to examine at least two layers that are exposed in the wall of an impact crater that’s less than 5 km across.
Cross Crater, about 65 kilometers in diameter, is located in the highlands of the Terra Sirenum region of Mars.
Data from other instruments, such as THEMIS and CRISM, imply that chlorides are present here; the CRISM data reveal that iron/magnesium clays are also present.
