How Perseverance's PIXL Gets Close to a Rock Target
Free
About
This time-lapse video, which has been sped up by 24 times, uses an engineering model of one of the instruments aboard NASA's Perseverance Mars rover to show how the instrument evaluates safe placement against a rock. If it's determined to be safe, the rover places the instrument, called the Planetary Instrument for X-ray Lithochemistry (PIXL), close to the targeted rock for science observations. This test occurred at NASA's Jet Propulsion Laboratory in Southern California on June 8, 2023. Located on the end of Perseverance's robotic arm, PIXL scans postage stamp-size areas on rocks with an X-ray beam the width of a human hair, determining which elements are present.
