Tantalizing opportunities for the six-wheeler’s science team while exploring a sediment-rich location in a Mars delta.
NASA’s Perseverance Mars rover has begun exploring a region near the base of Jezero Crater’s ancient river delta that the science team calls “Yori Pass.” They’ve been eager to explore the area for several months after spotting a rock similar to one Perseverance collected samples from in July.
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 NASA–ESA (European Space Agency) Mars Sample Return campaign, which began in September 2021 when the rover cached its first cored rock.

“We often prioritize study of fine-grained sedimentary rocks like this one in our search for organics and potential biosignatures,” said Katie Stack Morgan, Perseverance deputy project scientist at NASA’s Jet Propulsion Laboratory (JPL) in Southern California. “What’s especially interesting about the Yori Pass outcrop is that it is laterally equivalent with ‘Hogwallow Flats,’ where we found very fine-grained sedimentary rocks. That means that the rock bed is located at the same elevation as Hogwallow, and has a large, traceable footprint visible on the surface.”
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.
I give y’all this. No how many problems w finding life y’all hit or how many close ones always n so far tho… Come. You just won’t ever give up that the next ones gonna b the ONE .
. WHILE I DO BELIEVE THERE HAS TO BE LIFE OUT THERE. I THINK IT IS EXTREMELY LOW PROBABILITY THE LIFE IS INTELLIGENT ENOUGH NOT ONLY GET OFF THEIR OWN PLANET BUT TO HAVE FOUND A WAY TO TRAVEL ACROSS GALAXY AND ACROSS TRILLIONS OF LIGHT YEARS OF DISTANCE TO REACH OR EVEN NOTICE HER HALF-HEARTED ATTEMPT AT SPACE EXPLORATION
Not for nothing but finding ancient sign of life is history. Not Historic. Find real life. But don’t risk bringing it here.! We have enough. Go there and let us know.
I believe there is intelligence out there but like way out there or in parrell
