A member of NASA's Mars 2020 project checks connections between the spacecraft's back shell and cruise stage. The image was taken on March 26, 2019, in the Spacecraft Assembly Facility's High Bay 1 clean room at NASA's Jet Propulsion Laboratory, in Pasadena, California. During the mission's voyage to Mars, the cruise stage houses the hardware that steers and provides power to the spacecraft. The back shell, along with the heatshield (not pictured), protects the 2020 rover and the sky crane landing system during Mars atmospheric entry. https://photojournal.jpl.nasa.gov/catalog/PIA23163
