Perseverance will likely drop half of its rock samples in a depot in November or December.
rock cores to date — two apiece from seven target stones — and it will likely drop half of them in November or December, said mission team member Jim Bell of Arizona State University.Mars sample-return project
, which is a joint effort of NASA and the European Space Agency . The baseline plan calls for Perseverance to deliver its samples to a NASA lander that sports a built-in rocket, which will launch the Mars material to orbit. An ESA-provided orbiter will then snag the samples and haul them back to Earth. They could land here as soon as 2033.The lander, Mars rocket and ESA orbiter are currently scheduled to launch in the 2027-2028 timeframe.
"This is our backup sample cache, just in case the rover itself can't deliver samples," Bell, the principal investigator for Persevance's Mastcam-Z camera system, said during a livestreamed presentation Thursday at the 2022 Mars Society Convention., the little rotorcraft that landed on Jezero's floor with Perseverance last year and has aced more than 30 Red Planet flights since.
The depot Perseverance will establish in the next month or two is at a site dubbed Three Forks, which Bell said is a"pretty flat area." The topography is therefore favorable for safe helicopter landings and liftoffs.
