One of the MarCO CubeSats inside a cleanroom at Cal Poly San Luis Obispo, before being placed into its deployment box. The deployment box will eject the briefcase-sized CubeSat into space after launch. It and its twin will accompany the InSight Mars lander when it lifts off from Vandenberg Air Force Base in May.
The MarCO and InSight projects are managed for NASA's Science Mission Directorate, Washington, by JPL, a division of the California Institute of Technology, Pasadena.
