In its three years on Mars, NASA’s Perseverance rover has made outstanding strides in exploring the planet’s floor, uncovering proof of its water historical past and geological options that trace at the opportunity of historic life. The continued mission and anticipated pattern return effort promise to deepen our understanding of Mars and our place within the cosmos.
Within the three years since NASA’s Perseverance rover touched down on Mars, the NASA science crew has made the every day process of investigating the pink planet appear nearly mundane.
The rover and its helicopter sidekick Ingenuity have captured gorgeous photographs of Mars and picked up 23 distinctive rock core samples alongside 17 miles of an historic river delta.
One science crew member, College of Cincinnati Affiliate Professor Andy Czaja, stated he typically has to remind himself that the mission is something however abnormal.
“That is so cool. I’m exploring one other planet,” he stated.
Mission Highlights and Discoveries
Czaja teaches within the Division of Geosciences in UC’s Faculty of Arts and Sciences. He’s a paleobiologist and astrobiologist serving to NASA search for proof of historic life on Mars utilizing a rover outfitted with customized geoscience and imaging instruments with three of his UC graduate college students, Andrea Corpolongo, Brianna Orrill, and Sam Corridor.
Three years into the mission, the rover has carried out like a champ, he stated.
“Perseverance has excelled. It’s been incredible. It has such succesful instrumentation for doing the geology work. It’s capable of discover distant objects with its zoom lens cameras and may deal with tiny objects at unimaginable decision,” Czaja stated.

Alongside the best way, the mission has recorded numerous firsts: the primary powered flight, the primary recorded sounds of Mars, the longest autonomous drive (almost a half-mile), and new discoveries in regards to the planet’s geology, environment, and local weather.
Czaja was a part of the NASA crew that determined the place on Mars to land the rover. And he remained on the science crew that might pore over its every day information and discoveries to determine what the rover ought to do subsequent.
Geological Insights
Among the many new discoveries was discovering main igneous rocks in Jezero Crater. These rocks are the hardened results of liquid magma. They provide scientists promising clues about refining the identified age of the planet.
Scientists suspect Mars as soon as had long-lived rivers, lakes, and streams. Right now, water on Mars is present in ice on the poles and trapped under the Martian floor.
Czaja and his scholar Corpolongo had been co-lead authors of a paper revealed within the Journal of Geophysical Analysis, Planets that exposed that Mars additionally might have had hydrothermal programs primarily based on the hydrated magnesium sulfate the rover recognized within the volcanic rocks.
“When these rocks cool off and fracture, they change into a liveable surroundings for all times,” Czaja stated.
Corpolongo additionally led an identical analysis paper in the identical journal co-authored by Czaja detailing the outcomes of the rover’s evaluation of samples utilizing the SHERLOC deep ultraviolet Raman and fluorescence instrument. Each papers featured contributions from dozens of their fellow NASA researchers on the mission.
Samples collected by the rover might lastly reply the query about whether or not we’re alone within the universe.
The Quest for Historical Life
“Now we have not discovered any definitive proof of life in these deposits but. But when there have been fossil microorganisms trapped within the rocks, they’d be too small to see with the rover,” Czaja stated.
Czaja is hopeful funding might be authorised for the anticipated Mars Pattern Return mission to retrieve the hermetically sealed titanium tubes scientists have spent three years filling with attention-grabbing rock cores.
“These hydrated minerals lure water inside themselves and report the historical past of how and after they shaped,” the research stated. “Returning samples of those minerals to Earth would enable researchers to discover the historical past of Mars’ water and local weather and probably proof of historic life with probably the most delicate devices doable.”
The Journey Continues
However that was only the start. Perseverance started its deliberate exploration from the ground of the crater to the entrance of the delta, shaped by an historic river or drainage channel the place it encountered sedimentary rocks that always include trapped minerals and one other avenue for proof of historic life.
And final yr the rover made it to the crater’s margin in what was once an infinite lake the place it’s exploring deposits of magnesium carbonate, which might type geologically or biologically from micro organism.
Czaja stated the choice to ship Perseverance to Jezero Crater seems to be paying off.
“Completely. There have been different locations we might have gone that may have been simply pretty much as good,” he stated. “You gained’t know till you discover all of them. However Jezero was picked for good cause and it has been fully justified.”
The helicopter Ingenuity’s flying days seem like over after it sustained rotor harm in January after touchdown on its 72nd flight. However Perseverance remains to be going sturdy. It nonetheless has 15 pattern tubes at its disposal to seize extra attention-grabbing geologic specimens.
Subsequent the rover will make its approach out of Jezero Crater to discover the broader space. Czaja stated they’re prone to discover rocks relationship again 4 billion years or extra. And Mars might harbor stromatolites or rocks that include proof of historic layered mats of micro organism seen to the bare eye. On Earth, these rocks are typically present in excessive environments akin to geyser basins.
The horizon of discovery continues to broaden every day earlier than the science crew.
“I hope that Perseverance has simply whetted our urge for food for extra Martian exploration,” Czaja stated. “And bringing again samples will enable us to review Mars and seek for proof of historic life with devices that haven’t even been invented but for years and years to return.”
