"description": "NASA's Curiosity Mars rover used the camera at the end of its arm in April and May 2014 to take dozens of component images combined into this self-portrait where the rover drilled into a sandstone target called \"Windjana.\" The camera is the Mars Hand Lens Imager (MAHLI), which previously recorded portraits of Curiosity at two other important sites during the mission: \"Rock Nest\" and \"John Klein\".
Windjana is within a science waypoint site called \"The Kimberley,\" where sandstone layers with different degrees of resistance to wind erosion are exposed close together.
The view does not include the rover's arm. It does include the hole in Windjana produced by the hammering drill on Curiosity's arm collecting a sample of rock powder from the interior of the rock. The hole is surrounded by grayish cuttings on top of the rock ledge to the left of the rover. The Mast Camera (Mastcam) atop the rover's remote sensing mast is pointed at the drill hole. The hole is 0.63 inch (1.6 centimeters) in diameter. The rover's wheels are 20 inches (0.5 meter) in diameter.
Most of the component frames of this mosaic view were taken during the 613th Martian day, or sol, of Curiosity's work on Mars (April 27, 2014). Frames showing Windjana after completion of the drilling were taken on Sol 627 (May 12, 2014). The hole was drilled on Sol 621 (May 5, 2014).",

"description": "The Mars Science Laboratory’s Curiosity has the unique ability to capture self-portraits, or selfies. Curiosity uses the Mars Hand Lens Imager (MAHLI) located at the end of its robotic arm to capture sets of thumbnail images that are then stitched together to create full-color mosaics. The rover’s robotic arm is positioned out of the shot in the images, or portions of images, used to create the mosaics and therefore, is not visible.These images show Curiosity on October 31, 2012, October 5, 2015, and August 5, 2015. The October 2012 selfie was taken when the rover was located at \"Rocknest,” the spot in Gale Crater where the mission's first scoop sampling took place. The October 2015 selfie was taken nearly 3 years later, when the rover was located at the \"Big Sky” site, where its drill collected the mission's fifth taste of Mount Sharp. Lastly, the August 2015 selfie was taken when the rover was located at \"Buckskin” on lower Mount Sharp. Selfies like this one document the state of the rover and allow mission engineers to track changes over time such as dust accumulation and wheel wear shown here. For scale, the rover's wheels are 20 inches (50 centimeters) in diameter and about 16 inches (40 centimeters) wide. Only MAHLI (among the rover's 17 cameras) is able to image some parts of the craft, including the portside wheels. || ",
