NASA’s Perseverance Mars rover has completed constructing its backup pattern depot on the Crimson Planet.
The car-sized Perseverance rover simply stashed the final of the ten pattern tubes that comprise the depot. Phrase of the profitable drop got here in on Sunday evening (Jan. 29), about six weeks after the rover deployed the primary of the samples.
“It is official: @NASAPersevere has dropped the ultimate tube for the #MarsSampleReturn depot!” officers with NASA’s Jet Propulsion Laboratory (JPL) in Southern California, which manages Perseverance’s mission, said via Twitter on Monday (opens in new tab) (Jan. 30). “Ten samples have been deposited on the Martian floor and could possibly be returned to Earth for in-depth evaluation sooner or later.”

Perseverance landed in February 2021 on the ground of the 28-mile-wide (45 kilometers) Jezero Crater, which harbored an enormous lake and a river delta billions of years in the past.
The six-wheeled robotic is trying to find indicators of historic Mars life and amassing dozens of samples, which can be returned to Earth by a joint NASA-European Area Company (ESA) marketing campaign as early as 2033, if all goes based on plan.
The baseline sample-return structure requires Perseverance to ship a number of dozen samples to a rocket-equipped NASA lander on the Crimson Planet. That rocket will then ship the samples to Mars orbit, the place they’re going to be snagged and hauled to Earth by an ESA probe. Perseverance is the one one in every of these spacecraft that is at present operational; the ESA orbiter and NASA lander are scheduled to launch in 2027 and 2028, respectively.
Perseverance is in good situation now, however rather a lot can occur in 5 or 6 years. So the mission staff got here up with the depot as a backup plan, in case the rover is not in a position to ship the samples itself. Within the backup situation, two small helicopters will accumulate the tubes from the depot, which is in a patch of Jezero the staff calls Three Forks, and convey them again to the lander one after the other.
These helicopters will launch aboard the lander in 2028. They’re going to be primarily based closely on Ingenuity, the 4-pound (1.8 kilograms) chopper that launched with Perseverance as a expertise demonstration and continues to be going robust after 40 flights on the Red Planet.
The Three Forks samples, by the best way, are doubles; every one has a twin that Perseverance is carrying on its physique.
Perseverance deposited the ten tubes on the Three Forks depot in a zigzag sample, putting every one 15 to 50 toes (5 to fifteen meters) from its nearest neighbor to permit for simpler helicopter restoration.
“Including time to the depot-creation course of, the staff wanted to exactly map the placement of every 7-inch-long (18.6-centimeter-long) tube and glove (adapter) mixture in order that the samples could possibly be discovered even when coated with dust,” JPL officers wrote in an update on Monday (opens in new tab). “The depot is on flat floor close to the bottom of the raised, fan-shaped historic river delta that shaped way back when a river flowed right into a lake there.”
Now that its depot work is finished, Perseverance will head up the traditional delta, analyzing the intriguing rocks because it goes. After the rover passes an outcrop the staff calls Rocky High, will probably be in place to start a brand new phase of its science mission referred to as the Delta High Marketing campaign.
“We discovered that from the bottom of the delta as much as the extent the place Rocky High is situated, the rocks seem to have been deposited in a lake setting,” Perseverance Venture Scientist Ken Farley, of the California Institute of Expertise in Pasadena, stated in Monday’s replace.
“And people simply above Rocky High seem to have been created in or on the finish of a Martian river flowing into the lake,” Farley stated. “As we ascend the delta right into a river setting, we count on to maneuver into rocks which are composed of bigger grains — from sand to giant boulders. These supplies seemingly originated in rocks outdoors of Jezero, eroded after which washed into the crater.”
The Delta High Marketing campaign is predicted to last about eight months, mission staff members have stated.
