Curiosity: Taking aim at Pahrump

748-pahrump-aheadSol 748, September 13, 2014. Beyond the sand ripples ahead, the light patch in the center of this three-frame composite lies at the foot of the Pahrump Hills, the rover’s next science operations target. The rover science team reported last week that they believe these rocks belong to the Murray Formation, the layer thought to underlie the entire stack of sediments making up Mount Sharp. Examining the water-altered sediments of the mound is the prime goal for the rest of Curiosity’s mission.

(The Murray Buttes, a topographical feature often noted as a landmark for the rover’s trek to Mount Sharp, should not be confused with the Murray Formation. The buttes lie farther to the southwest from the rover’s current position, and they are remnants of a different geological unit: the crater-floor sediments which the rover has been driving on since landing.)

CRISM: Extensional features from the horizon

CRISM_FeaturedImage_LMB2B67_CompressedThe image shows a limb (meaning a view of the horizon) of the planet where the surface can be seen at the bottom, the atmosphere in the middle, and space is above in black. In order to make these observations, the MRO spacecraft must pitch onto its side so CRISM no longer looks down at the surface, but instead out onto the horizon of the planet… [More at link]

Opportunity: Ulysses Crater strewn field

3780-strewn-fieldSol 3780, September 11, 2014. Off the rear of the rover lies a strewn field of rocks, most of them likely ejecta from the Ulysses Crater impact. The lower slopes of the crater lie at upper right in this three-frame-Navcam composite.

Curiosity update: ‘Pahrump Hill mosaic’

Sol 747, September 11, 2014, update from USGS Scientist Ken Herkenhoff: “The Sol 746 drive put the rover in a good location for imaging the terrain ahead, which looks good for a long drive on Sol 747.  The Sol 746 data did not hit the… [More at link]

HiRISE: Banded TARs in Iapygia

ESP_020782_1610The tropics of Mars are commonly littered with small bright ripples that were somehow shaped by the wind. Called “transverse aeolian ridges”, or TARs, the features stand up to 6 meters tall and are spaced a few tens of meters apart. They are typically oriented… [More at link]
