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.
  • Main Job is to Seek signs of ancient life and collect samples of rock and regolith (broken rock and soil) for possible return to Earth.
  • The rover will collect samples of rock and soil, encase them in tubes, and leave them on the planet’s surface to be returned to Earth at a future date.
  • It was launched on July 30, 2020 from Cape Canaveral, Florida.
  • Successfully landed on the surface of Mar’s Jezero Crater on Feb. 18, 2021.
  • It is about 3 metres long, 2.7 metres wide, and 2.2 metres tall.
  • It is about the size of a car, but weighs only about 1,025 kilograms with all instruments on board.
  • Power source is Multi-Mission Radioisotope Thermoelectric Generator (MMRTG).
  • Converts heat from the radioactive decay of plutonium into electricity.
