HiRISE images for May 5, 2010
Thu May 6, 2010 at 05:18 UTC
The following new captioned images taken by the High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter spacecraft are now available:
- Geezer Gullies at Tempe Terra
This image shows gullies in the walls of a large impact crater in Tempe Terra. - Viscous Flow in Protonilus Mensae
This subimage highlights a feature that resembles a terrestrial glacier, indicating that material has viscously flowed at this location. - Star Dunes in Crater in Tyrrhena Terra
An amazing aspect of Mars that is captured in many HiRISE images is geologic diversity within a small area. - Icy Northern Dunes
Like Earth, Mars has seasonal polar caps that grow in the winter and retreat in the spring, but on Mars the seasonal caps are composed primarily of carbon dioxide (dry ice). - Pits along Fractures in Crater Floor Material
This image shows the degraded rim of a large impact crater which is partly filled with material that is fractured in several places, especially near the crater rim. - Collapse!
This observation shows part of an unnamed crater whose fill material has collapsed. - Intra-Crater Structure in NW Hellas Basin
This area of Hellas Basin has a number of unusual features which are thought to be quite old because of the high crater density. - Big Impact-Triggered Dust Avalanche
MRO's Context camera (CTX) acquired the image at lower left on18 Nov 2007 and the adjacent image on 14 Feb 2010, showing a large new slope streak in the aureole (giant landslide deposits) of Olympus Mons. - Megabreccia in the Central Uplift of Stokes Crater
Stokes is a large, approximately 60 kilometer diameter (38 miles) impact crater located in the Northern lowland plains of Mars. - Deformed Craters and Polygons in Utopia Planitia
This image of Utopia Planitia shows some deformed craters. The crater rims are not round but elliptical and even angular. - Knobs near Reull Vallis
This observation shows a knob and large crater near Reull Vallis, east of the Hellas Basin. - Light-Toned Rocks inside a Crater
This approximately 20 kilometer diameter impact crater is located just to the south of Coprates Chasma in Valles Marineris.
