Cache and Carry

Aug. 15, 2019
In this August 5, 2019 image, the bit carousel, the heart of sampling and caching subsystem of NASA's Mars 2020 mission, is attached to the front end of the rover.

The bit carousel, which lies at the heart of Sample Caching System of NASA's Mars 2020 mission, is attached to the front end of the rover in the Spacecraft Assembly Facility's High Bay 1 at the Jet Propulsion Laboratory in Pasadena, California. The carousel contains all of the tools the coring drill uses to sample the Martian surface and is the gateway for the samples to move into the rover for assessment and processing. The image was taken on Aug. 5, 2019.

JPL is building and will manage operations of the Mars 2020 rover for the NASA Science Mission Directorate at the agency's headquarters in Washington.
