The adaptive caching cycle proposed for the Mars 2020 rover After landing, the rover would drill and store soil samples in sealed tubes. At the team’s discretion, groups of these sample tubes would be placed at strategic ‘cache depots’ for a future retrieval mission. This can repeat as needed until the Mars 2020 is out of sampling tubes. Casey Dreier / JPL-Caltech
