Tantalizing opportunities for the six-wheeler’s science team while exploring a sediment-rich location in a NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion."

Scientists find the feature so tantalizing because it is sandstone, which is composed of fine grains that have been carried from elsewhere by water before settling and forming stone. Samples that Perseverance collects are central to the first step in the NASAESA (European Space Agency) Mars Sample Return campaign, which began in September 2021 when the rover cached its first cored rock.

The rocks at Hogwallow Flats appear to be very fine-grained, which is exciting to scientists on the mission as fine-grained rocks may have the best chance at preserving evidence of life.

One of the Perseverance rover’s four science objectives is the hunt at Jezero Crater for biosignatures (any characteristic, molecule, element, substance, or feature that can serve as evidence for ancient life). Along with its 14 rock-core samples, the rover has collected three witness tubes and one atmospheric sample, all of which are stored in the rover’s belly.

After it collects a sample from Yori Pass, Perseverance will drive 745 feet (227 meters) southeast to a mega sand ripple. Located in the middle of a small dune field, the ripple – called “Observation Mountain” by the science team – will be where the rover collects its first samples of regolith, or crushed rock and dust.

More About the Mission

One of the key objectives for Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

Subsequent NASA missions, in cooperation with ESA, would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

JPL, which is managed for NASA by Caltech, built and manages operations of the Perseverance rover.
