10. NASA Jet Propulsion Laboratory’s tweet on the development of Mars 2020 spacecraft

Scientists at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena have successfully completed a separation test of the rocket-powered descent stage of the Mars 2020 spacecraft, a Mars rover mission managed by NASA’s Mars Exploration Program (MEP).

Being developed by JPL, the Mars 2020 will collect samples and store them in containers, which will be returned to Earth by a potential future Mars sample-return mission. Scheduled to be launched aboard an Atlas V rocket from Cape Canaveral Air Force Station in July 2020, the rover will land at Jezero crater on Mars  in February 2021.
