Curiosity: Beams back new colour images and Health check continues.


Curiosity is healthy as it continues to familiarize itself with its new home in Gale Crater and check out its systems. The team's plans for Curiosity checkout today included raising the rover's mast and continued testing of its high-gain antenna, whose pointing toward Earth will be adjusted on Sol 2. Science data were collected from Curiosity's Radiation Assessment Detector, and activities were performed with the Rover Environmental Monitoring Station instrument. Curiosity transmitted its first color image from the surface of Mars, from the Mars Hand Lens Imager, or MAHLI, showing part of the north rim of Gale Crater. Additional calibration images were received from Curiosity's Navcam and Mastcam. All systems are go for deployment of the rover's remote sensing mast on Sol 2, followed by a 360-degree pan by the rover's Navcam.

The four main pieces of hardware that arrived on Mars with NASA's Curiosity rover were spotted by NASA's Mars Reconnaissance Orbiter (MRO). The High-Resolution Imaging Science Experiment (HiRISE) camera captured this image about 24 hours after landing. 




The Curiosity rover is in the center of the image. To the right, approximately 4,900 feet (1,500 meters) away, lies the heat shield, which protected the rover from 3,800-degree-Fahrenheit (about 2,100 degrees Celsius) temperatures encountered during its fiery descent. On the lower left, about 2,020 feet (615 meters) away, are the parachute and back shell. The parachute has a constructed diameter of 71 feet (almost 21.5 meters) and an inflated diameter of 51 feet (nearly 16 meters). The back shell remains connected to the chute via 80 suspension lines that are 165 feet (50 meters) long. To the upper-left, approximately 2,100 feet (650 meters) away from the rover, is a discoloration of the Mars surface consistent with what would have resulted when the rocket-powered Sky Crane impacted the surface.



 This image comparison shows a view through a Hazard-Avoidance camera on NASA's Curiosity rover before and after the clear dust cover was removed. Both images were taken by a camera at the front of the rover. Mount Sharp, the mission's ultimate destination, looms ahead.  









 This picture of the Martian landing site of NASA's Curiosity rover puts a color view obtained by the rover in the context of a computer simulation derived from images acquired from orbiting spacecraft. The view looks north, showing a distant ridge that is the north wall and rim of Gale Crater.

The color image was obtained by Curiosity's Mars Hand Lens Imager (MAHLI) on Aug. 6 PDT (Aug. 7 UTC), the first Martian day after Curiosity's landing on Aug. 5 PDT (Aug. 6 UTC). It has been rendered about 10 percent transparent so that scientists can see how it matches the simulated terrain in the background. The MAHLI image was taken while the camera's transparent dust cover was still on. Curiosity's descent coated the cover with a thin film of dust.

The peak seen on the left-side of the MAHLI image is about 15 miles (24 kilometers) distant with a height of about 3,775 feet (1,150 meters) high. The box with arrows at the upper left indicates direction. The arrow pointing up is "up" with respect to the gravity of Mars. The arrow pointing to the right is east. North would be an arrow pointing into the image (that is, the MAHLI view is toward the north).

The MAHLI is located on the turret at the end of Curiosity's robotic arm. At the time the MAHLI image was acquired, the robotic arm was in its stowed position. It has been stowed since the rover was packaged for its Nov. 26, 2011, launch. 




This image is a 3-D view behind NASA's Curiosity rover, which landed on Mars on Aug. 5 PDT (Aug. 6 EDT). The anaglyph was made from a stereo pair of Hazard-Avoidance Cameras on the rear of the rover. It has been cropped. Part of the rim of Gale Crater, which is a feature the size of Connecticut and Rhode Island combined, stretches from the top middle to the top right of the image. One of the rover's wheels can be seen at bottom right. The bright spot is saturation from the sun.




This image is a 3-D view in front of NASA's Curiosity rover, which landed on Mars on Aug. 5 PDT (Aug. 6 EDT). The anaglyph was made from a stereo pair of Hazard-Avoidance Cameras on the front of the rover. The image is cropped but part of Mount Sharp, a peak that is about 3.4 miles (5.5 kilometers) high, is still visible rising above the terrain. This image was captured by the rover's front left Hazard-Avoidance camera at full resolution shortly after it landed.
