HiRISE: High Resolution Imaging Science Experiment
The objective of this observation is to examine a small channel on an old crater wall. The channel has cut through the rim in two places, and this scene, located north of the Hellas region, is also visible in Context Camera data. (NASA/JPL-Caltech/UArizona)
This observation features a possibly multi-layered lobe that might be ejecta from craters on southwest rim of the crater in which they occur. They could also be landslide deposits that pre-date those impacts, meaning that the ejecta had to have eroded away before re-exposing landslide lobes. Either way, the erosional expression is suggestive that the...
The objective of this observation is to examine gullies in an impact crater. Pictures like this one will help increase our inventory of Martian gullies, and perhaps lead to improved models. This scene is visible in CTX image P15_007045_1429. These gullies are quite small. (NASA/JPL-Caltech/UArizona)
This image was requested to capture as much of the dune field at the center of an impact crater as possible in order to investigate seasonal dune and frost monitoring. (NASA/JPL-Caltech/UArizona)
Also visible in Context Camera data, in this observation are we seeing stream channels from the northwest wall of an impact crater that are now lithified and standing in relief because of differential erosion? Or something else? (NASA/JPL-Caltech/UArizona)
While perhaps not awe-inspiringly beautiful, sand sheets can tell us about Mars’ current and past environmental conditions as a piece of the puzzle for understanding habitability. (NASA/JPL-Caltech/UArizona)
