Improved OPTIMISM

Updated with new features, including additional mobility software and the bulk of the sample caching system, the Earthly twin of NASA's Perseverance Mars rover arrives at the Mars Yard garage at the agency's Jet Propulsion Laboratory on Oct. 29, 2021. The vehicle is generically referred to as a vehicle system test bed but goes by the name OPTIMISM (short for Operational Perseverance Twin for Integration of Mechanisms and Instruments Sent to Mars). As with vehicle system test beds for other Mars rovers, OPTIMISM is used to test moves and scenarios in the Mars Yard's simulated Red Planet landscape to help ensure that its twin on Mars can safely execute the commands sent by Earth-bound controllers. The tests could also potentially reveal unexpected problems Perseverance might encounter. With longer drives in Perseverance's near future, another job for OPTIMISM will involve presenting new challenges to the rover's autonomous navigation system, or AutoNav. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the
