Mars-Curiosity-Chroniken - Curiosity OnTour-Sol 25


Curiosity Daily Status Report for Aug. 31, 2012

Curiosity took a sol off from driving and spent time during the mission's Sol 25, on Aug. 31, 2012, taking images and collecting environmental monitoring data.

Imaging tasks for the sol included Navigation Camera sky observations to check for clouds, and Mast Camera imaging of the terrain eastward where the rover will be driving during the next few sols. In addition, the Mast Camera was used for taking a 360-degree panorama from the location that Curiosity reached by its Sol 24 drive.

Sol 25, in Mars local mean solar time at Gale Crater, ends at 11:59 p.m. Aug. 31, PDT.


Orbiter View of Curiosity From Nearly Straight Overhead

Details such as the shadow of the mast on NASA's Mars rover Curiosity appear in an image taken Aug. 17, 2012, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter, from more directly overhead than previous HiRISE images of Curiosity. In this product, cutouts showing the rover and other hardware or ground markings from the landing of the Mars Science Laboratory spacecraft are presented across the top of a larger, quarter-resolution overview keyed to the full-resolution cutouts. North is up. The scale bar is 200 meters (one-eighth of a mile).

Curiosity landed Aug. 5, PDT (Aug. 6, EDT). HiRISE imaged the spacecraft during its descent PIA15993, on the first day after landing PIA16001 and on the sixth day after landing PIA16057 . This image was acquired looking more directly down (9 degree roll angle) than the prior images so the pixel scale is improved to approximately 11 inches (27 centimeters) per pixel. Each cutout is individually stretched to best show the information without saturation. A special noise cleaning method was applied to the images by Paul Geissler of U.S. Geological Survey.

The shadow of Curiosity's mast extends southeast from the rover, opposite the solar illumination direction.

Dark spots on the left-side cutouts created streaks radial to the descent-stage impact site. They may be from far-flung rocks or objects associated with the impact. Seven bright spots associated with the descent stage crash site, as well, may be pieces of hardware.

There are also bright pieces scattered around the backshell, mostly downrange, and interesting detail in the parachute.

The rover is approximately 4,900 feet (1,500 meters) away from the heat shield, about 2,020 feet (615 meters) away from the parachute and back shell, and approximately 2,100 feet (650 meters) away from the discoloration consistent with the impact of the sky crane.
