The Perseverance Rover (nicknamed 'Percy') recently completed building a sample depot on Mars. This is the first time that a sample repository of this kind has been constructed in another world and this also marks a big milestone for the mission. NASA, along with ESA, aims to bring samples from Mars to Earth for closer study, via the Mars Sample Return campaign.
