NASA’s Perseverance Mars rover is wrapping up its prime mission on the Purple Planet.
The car-sized Perseverance rover landed on the ground of Mars’ Jezero Crater on Feb. 18, 2021, kicking off an bold floor mission designed to final one Purple Planet 12 months, which is about 687 Earth days.
That point is now up; the Mars calendar turned for Perseverance on Friday (Jan. 6). However do not fret: The six-wheeled robotic will transition seamlessly into an prolonged mission on Saturday (Jan. 7).

Perseverance has two essential duties on the Purple Planet. The rover is looking for doable indicators of Mars life on the ground of the 28-mile-wide (45 kilometers) Jezero, which hosted an enormous lake and a river delta billions of years in the past. Perseverance can also be amassing and caching dozens of samples, which a joint NASA-European House Company (ESA) marketing campaign will bring to Earth for detailed research within the early 2030s, if all goes based on plan.
That marketing campaign will launch a rocket-toting NASA lander in addition to an ESA Earth-return orbiter to the Purple Planet within the mid to late 2020s. The plan requires Perseverance to drive its samples over to the lander; the rocket will then launch the valuable cargo to Mars orbit, the place the ESA probe will snag it and haul the fabric again to Earth.
Perseverance has made loads of progress on the sampling entrance so far. The rover has already stuffed up and sealed 18 of its 38 titanium sampling tubes (opens in new tab) in addition to three of its 5 “witness tubes,” which can assist mission staff members assess the cleanliness of Perseverance’s sampling system.
And the rover has begun caching samples, too, so far dropping four of a planned 10 tubes on a patch of Jezero’s ground that the mission staff calls Three Forks. This depot is a backup, to cowl for the chance that Perseverance will not have the ability to ferry its samples to the lander when the time comes. (The rover is in good condition now, however there is not any assure its well being will maintain via the tip of the last decade.)
In that case, two small helicopters that may launch aboard the lander will fetch the pattern tubes from the depot one after the other.
With this hedge in thoughts, the mission staff has been amassing two samples from every of its goal rocks. Perseverance is preserving one set on board and caching the opposite set.
The fetch helicopters might be primarily based closely on Ingenuity, the 4-pound (1.8 kilograms) chopper that traveled to Mars with Perseverance.
Ingenuity’s essential job was to indicate that aerial exploration is feasible on Mars regardless of the planet’s thin atmosphere, which is simply 1% as dense as that of Earth at sea stage. The little rotorcraft shortly achieved that objective throughout a five-flight demonstration marketing campaign and is now serving as a scout for Perseverance on an bold prolonged mission.
Ingenuity now has 37 flights underneath its belt, which collectively have coated a total of 4.7 miles (7.6 kilometers). Perseverance, for its half, has racked up practically 8.7 miles (14.0 km) of off-Earth driving, and that total will climb significantly throughout its prolonged mission.
After it finishes dropping samples on the Three Forks depot, Perseverance will head for the highest of Jezero’s historical river delta, seemingly ending the climb in February. The rover will then discover the area for the following eight months or so, searching for, amongst different issues, rocks that have been washed into the crater by Jezero’s historical river.
“The Delta High Marketing campaign is our alternative to get a glimpse on the geological course of past the partitions of Jezero Crater,” Perseverance deputy undertaking scientist Katie Stack Morgan, of NASA’s Jet Propulsion Laboratory in Southern California, stated in a statement last month (opens in new tab).
“Billions of years in the past, a raging river carried particles and boulders from miles past the partitions of Jezero,” she stated. “We’re going to discover these historical river deposits and acquire samples from their long-traveled boulders and rocks.”
