full-scale engineering model of NASA's Perseverance rover

September 04, 2020

The full-scale engineering model of NASA's Perseverance rover raises its "head," or remote sensing mast, at NASA's Jet Propulsion Laboratory in Southern California. This model is known as the vehicle system test bed (VSTB) rover, or OPTIMISM (Operational Perseverance Twin for Integration of Mechanisms and Instruments Sent to Mars). OPTIMISM raised its mast shortly after moving into its new home at JPL's Mars Yard on Sept. 4, 2020.

The mast hosts many of the rover’s cameras and scientific instruments. At the top of the mast, the large circular opening is where the SuperCam instrument will be installed on this test rover. Also visible in these images below the SuperCam “eye” are the navigation cameras (two cameras closest to the outside of the head) and the Mastcam-Z cameras inside of the navigation cameras.

A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will also characterize the planet's climate and geology, pave the way for human exploration of the Red Planet, and be the first planetary spacecraft to collect and cache Martian rock and regolith (broken rock and dust). Subsequent missions, currently under consideration by NASA in cooperation with the European Space Agency, would send spacecraft to Mars to collect these cached samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 mission is part of a larger program that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. Charged with returning astronauts to the Moon by 2024, NASA will establish a sustained human presence on and around the Moon by 2028 through NASA's Artemis lunar exploration plans.

JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
