Engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, have installed the SuperCam Mast Unit onto the Mars 2020 rover to probe the Jezero Crater landing site with its landforms reaching as far back as 3.6 billion years. “It will revolutionize how we think about Mars and its ability to harbor life,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate.
