NASA’s Perseverance rover is getting set to lighten its load a bit on the Purple Planet.
Perseverance landed inside Mars’ Jezero Crater in February 2021 to hunt for indicators of historic Purple Planet life and gather samples for future return to Earth. The car-sized rover has drilled out 14 Mars rock cores thus far — two apiece from seven goal stones — and it’ll seemingly drop half of them in November or December, mentioned mission crew member Jim Bell of Arizona State College.
That is the alternative of carelessness; it is a safeguard designed to guard the general Mars sample-return venture, which is a joint effort of NASA and the European House Company (ESA). The baseline plan requires Perseverance to ship its samples to a NASA lander that sports activities a built-in rocket, which can launch the Mars materials to orbit. An ESA-provided orbiter will then snag the samples and haul them again to Earth. They might land right here as quickly as 2033.

The lander, Mars rocket and ESA orbiter are at present scheduled to launch within the 2027-2028 timeframe. Perseverance is in good well being, however there’s an opportunity the rover will not be doing so nicely when that different {hardware} arrives on the Purple Planet. Therefore the approaching depot drop, which can contain one pattern from every drilled rock. (Perseverance will hold the opposite pattern set onboard.)
“That is our backup pattern cache, simply in case the rover itself cannot ship samples,” Bell, the principal investigator for Persevance’s Mastcam-Z digicam system, mentioned throughout a livestreamed presentation Thursday (Oct. 20) on the 2022 Mars Society Conference.
The NASA sample-return lander will carry two small helicopters, every of them modeled on Ingenuity, the little rotorcraft that landed on Jezero’s flooring with Perseverance final 12 months and has aced greater than 30 Purple Planet flights since. If want be, the 2 choppers will carry pattern tubes, one after the other, from the depot — or depots, as there might find yourself being a couple of — to the lander. (“Depot” is a barely overgrand time period for a spot the place tubes shall be mendacity within the grime.)
The depot Perseverance will set up within the subsequent month or two is at a website dubbed Three Forks, which Bell mentioned is a “fairly flat space.” The topography is due to this fact favorable for protected helicopter landings and liftoffs.
Perseverance has some work to do earlier than it will probably head over to Three Forks, nevertheless. It is at present amassing regolith — samples of Martian sand and mud — and can seemingly proceed doing so by way of subsequent week, Bell mentioned.
Perseverance carries a complete of 43 titanium tubes, 38 of that are designed to carry samples. The opposite 5 are “witness tubes” that may assist mission crew members decide which supplies, if any, in collected Martian samples could also be contaminants from Earth.
The rover has crammed 15 of its sampling tubes thus far, 14 of them with drilled rock cores (although the crew is having bother sealing up the tube with essentially the most not too long ago collected core). The opposite crammed tube comprises an “atmospheric pattern” — Martian air however nothing else, the results of a drilling effort that went awry because of a surprisingly crumbly rock.
