The following image from NASA’s Curiosity rover was taken by the left mast camera (Mastcam). It shows an image of the camera on the rover’s robotic arm, the Mars Hand Lens Imager (MAHLI), during the 30th Martian day, or sol, of the rover’s mission on Mars. MAHLI is one of the various tools that sit on the end of Curiosities robotic arm and is used to explore the near surrounding on Mars. After several days traveling and driving on Mars NASA’s rover Curiosity starts to test these tools on it’s robotic arm. NASA is spending several days preparing for full use of the tools on its arm.
“We will be putting the arm through a range of motions and placing it at important ‘teach points’ that were established during Earth testing, such as the positions for putting sample material into the inlet ports for analytical instruments,” said Daniel Limonadi of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., lead systems engineer for Curiosity’s surface sampling and science system. “These activities are important to get a better understanding for how the arm functions after the long cruise to Mars and in the different temperature and gravity of Mars, compared to earlier testing on Earth.”
The image below shows the exact location of the arm on NASA’s Curiosity rover, in addition to the arm’s turret, which holds two instruments and three tools. Image credit: NASA/JPL-Caltech:
