In the Belly of the Mars 2020 Beast

In this image, taken on June 1, 2019, an engineer in the Spacecraft Assembly Facility's High Bay 1 at NASA’s Jet Propulsion Laboratory in Pasadena, California, can be seen working on the exposed belly of the Mars 2020 rover. It has been inverted to allow the 2020 engineers and technicians easier access. The front of the rover is on camera left. The engineer is inspecting wiring directly above the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) instrument. MOXIE will demonstrate a way that future explorers might produce oxygen from the Martian atmosphere for propellant and for breathing.

In the foreground, just to the left of center and distinctive because of the relative lack of wiring, is the body unit for the SuperCam instrument. The mast unit for SuperCam instrument, which will provide imaging, chemical composition analysis and mineralogy from its high perch at the top of the rover's remote sensing mast was installed June 25.

To the far left, covered by a red-colored shield, is the bay where the Adaptive Caching Assembly (ACA) will document, analyze and process for storage samples of Mars rock and soil for future return to Earth.
