The rover has racked up a collection of accomplishments, together with new distance data, because it reaches the tip of the primary of a number of deliberate science campaigns on the Purple Planet.
NASA’s Perseverance rover has notched up a slew of firsts since touching down on Mars one 12 months in the past, on February 18, 2021, and the six-wheeled scientist has different vital accomplishments in retailer because it speeds towards its new vacation spot and a brand new science marketing campaign.
Weighing roughly 1 ton (1,025 kilograms), Perseverance is the heaviest rover ever to the touch down on Mars, returning dramatic video of its touchdown. The rover collected the primary rock core samples from one other planet (it’s carrying six thus far), served as an indispensable base station for Ingenuity, the primary helicopter on Mars, and examined MOXIE (Mars Oxygen In-Situ Useful resource Utilization Experiment), the primary prototype oxygen generator on the Purple Planet.

Perseverance additionally just lately broke a file for probably the most distance pushed by a Mars rover in a single day, touring nearly 1,050 ft (320 meters) on February 14, 2022, the 351st Martian day, or sol, of the mission. And it carried out the whole drive utilizing AutoNav, the self-driving software program that permits Perseverance to seek out its personal path round rocks and different obstacles.
The rover has almost wrapped up its first science marketing campaign in Jezero Crater, a location that contained a lake billions of years in the past and options a number of the oldest rocks Mars scientists have been capable of research up shut. Rocks which have recorded and preserved environments that after hosted water are prime places to seek for indicators of historical microscopic life.

Utilizing a drill on the tip of its robotic arm and a complicated pattern assortment system in its stomach, Perseverance is snagging rock cores from the crater flooring – step one within the Mars Pattern Return marketing campaign.
“The samples Perseverance has been accumulating will present a key chronology for the formation of Jezero Crater,” mentioned Thomas Zurbuchen, affiliate administrator of NASA’s Science Mission Directorate in Washington. “Every one is fastidiously thought of for its scientific worth.”

Counting the Eons
Two extra samples shall be collected in coming weeks from the “Ch’al” rock sort (named with the Navajo time period for “frog”), a set of darkish, rubbly rocks consultant of what’s seen throughout a lot of the crater flooring. If samples of those rocks are returned to Earth, scientists assume they might present an age vary for Jezero’s formation and the lake that after resided there.
Scientists can approximate the age of a planet or moon’s floor by counting its affect craters. Older surfaces have had extra time to build up affect craters of assorted sizes. Within the case of the Moon, scientists had been capable of refine their estimates by analyzing Apollo lunar samples. They’ve taken these classes to slender down the age estimates of surfaces on Mars. However having rock samples from the Purple Planet would enhance crater-based estimates of how previous the floor is – and assist them discover extra items of the puzzle that's Mars’ geological historical past.
“Proper now, we take what we all know in regards to the age of affect craters on the Moon and extrapolate that to Mars,” mentioned Katie Stack Morgan, Perseverance’s deputy undertaking scientist at NASA’s Jet Propulsion Laboratory in Southern California, which manages the rover mission. “Bringing again a pattern from this closely cratered floor in Jezero may present a tie-point to calibrate the Mars crater relationship system independently, as a substitute of relying solely on the lunar one.”
The mission hasn’t been with out challenges. The rover’s first try at drilling a rock core got here up empty, prompting an intensive testing marketing campaign to raised perceive fragile rocks. The staff additionally wanted to filter out pebbles that had dropped into the a part of the sampling system that holds the drill bits.
Perseverance’s airborne companion, NASA’s Ingenuity Mars Helicopter, has confirmed equally plucky: It was grounded for nearly a month following a mud storm earlier than just lately resuming its flights. Initially slated to fly 5 occasions, the rotorcraft has efficiently accomplished 19 flights now, offering a brand new perspective of Martian terrain and serving to Perseverance’s staff to plan the trail forward.
To the west of “Octavia E. Butler Touchdown,” the place Perseverance began its journey, are the stays of a fan-shaped delta fashioned by an historical river because it fed the lake in Jezero Crater. Deltas accumulate sediment over time, probably trapping natural matter and potential biosignatures – indicators of life – that could be within the surroundings. That makes this vacation spot, which the mission expects to succeed in this summer season, a spotlight of the 12 months to come back.
Extra About Perseverance
A key goal for Perseverance’s mission on Mars is astrobiology, together with the seek for indicators of historical microbial life. The rover will characterize the planet’s geology and previous local weather, pave the best way for human exploration of the Purple Planet, and be the primary mission to gather and cache Martian rock and regolith (damaged rock and mud).
Subsequent NASA missions, in cooperation with ESA (European Area Company), would ship spacecraft to Mars to gather these sealed samples from the floor and return them to Earth for in-depth evaluation.
The Mars 2020 Perseverance mission is a part of NASA’s Moon to Mars exploration method, which incorporates Artemis missions to the Moon that may assist put together for human exploration of the Purple Planet.
JPL, which is managed for NASA by Caltech in Pasadena, California, constructed and manages operations of the Perseverance rover.
