On the Rim of Oudemans Crater

On the Rim of Oudemans Crater
The purpose of this observation is to capture the degraded rim of Oudemans Crater to the northeast. Specifically, we wish to observe the possible impact melt rock on the floor of Oudemans that may have flowed into the canyons to the northeast of the crater. Unlike some craters, Oudemans Crater does not have alluvial fans on its floor. In places, its rim has a terrace. It was named for Dutch astronomer Jean Abraham Chrétien Oudemans.  
Little Crater, Full of Ice

Little Crater, Full of Ice
Ice fill within this impact crater in the North Polar layered deposits may be a site where accumulation could be observed, helping to settle a long-term problem in Mars polar science: are these deposits currently gaining or losing mass? This crater is approximately 136 meters (446 feet) across. But this is likely dry ice, so no drinking!   
Wonders of Mawrth

Wonders of Mawrth
Often appearing as a candidate landing site, Mawrth Vallis is a topographical wonderland of inverted channels, light-toned rocks and clays. Clay minerals have implications for past wet environments along with the potential to preserve biosignatures. This public request was made to investigate the regional stratigraphy and reasons for the topographic inversion.  
The Pitted Crater

The Pitted Crater
This pit at the center of a northern plains impact crater somewhat resembles ice exposures, but doesn’t look clean. Could it be ice under a thin lag? The CRISM instrument can provide information if ice is being exposed here. We also want to look for active slope retreat of the crater walls.
