NASA’s Perseverance Rover : First Sample Depot
NASA’s Perseverance rover recently completed the first “sample depot on another world” by dropping the tenth and final sample tube.
- The tube will be part of a depot that will be considered for the return to Earth as part of the Mars Sample Return Campaign.
- Perseverance rover is robotic explorer to land on Mars as part of NASA’s ongoing Mars 2020 Mission.
