Curiosity Beaming Back Images of Landing From Mars


Nailing Down Curiosity's Landing Site

This image shows the location (green) where scientists estimate NASA's Curiosity rover landed on Mars within Gale Crater, based on images from the Mars Descent Imager (MARDI). The landing estimates derived from navigation and landing data agree to within 660 feet (200 meters) of this MARDI estimate.

The red line shows the northern edge of the targeted landing region, a probability distribution defined by an ellipse.

The gray scale image is a mosaic from the HiRISE camera on NASA's Mars Reconnaissance Orbiter. The color image is from MARDI.

Curiosity's Landscape Portrait in Context

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.

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 computer simulation is a digital elevation model that incorporates data from the High Resolution Imaging Science Experiment (HiRISE) and Context Camera on NASA's Mars Reconnaissance Orbiter and the High Resolution Stereo Camera on ESA's Mars Express. 

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. 

When the robotic arm, turret and MAHLI are stowed, the MAHLI is in a position that is rotated 30 degrees relative to the rover deck. The MAHLI image shown here has been rotated to correct for that tilt, so that the sky is "up" and the ground is "down." Here, MAHLI is looking out from the front left side of the rover. This is much like the view from the driver's side of cars sold in the U.S. 

The main purpose of Curiosity's MAHLI camera is to acquire close-up, high-resolution views of rocks and soil at the rover's Gale Crater field site. The camera is capable of focusing on any target at distances of about 0.8 inch (2.1 centimeters) to infinity. This means it can, as shown here, also obtain pictures of the Martian landscape. This was the first time the MAHLI focus mechanism was operated since before launch and it performed flawlessly. 

3-D View from the Front of Curiosity

NASA's Mars Science Laboratory Image
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. It has been linearized to remove the distorted appearance that results from its fisheye lens. A single "eye" view of Mount Sharp is available at PIA15986. 

Clear Views on Mars

This imagery is being released in association with NASA's Mars Science Laboratory mission. This is a temporary caption to be replaced as soon as more information is available.

3-D View from Behind Curiosity

NASA's Mars Science Laboratory Image
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. 

The original images were captured by the rover's front Hazard-Avoidance cameras at full resolution shortly after the rover landed. It has been linearized to remove the distorted appearance that results from its fisheye lens. A single "eye" view from the rear of the rover is available at http://photojournal.jpl.nasa.gov/catalog/PIA15987 .
