The extraordinary sample-gathering system of NASA's Perseverance Mars rover

The samples Apollo 11 brought back to Earth from the Moon were humanity's first from another celestial body. NASA's upcoming Mars 2020 Perseverance rover mission will collect the first samples from another planet (the red one) for return to Earth by subsequent missions. In place of astronauts, the Perseverance rover will rely on the most complex, capable and cleanest mechanism ever to be sent into space, the Sample Caching System.
