Sol 1009: Deciphers Ancient History of Martian Lake
The panorama is made up of 190 individual Mastcam-Z images stitched together. The images were taken on Sol 1009 (December 22, 2023).
Marking its 1,000th Martian day on the Red Planet, NASA’s Perseverance rover recently completed its exploration of the ancient river delta that holds evidence of a lake that filled Jezero Crater billions of years ago. The six-wheeled scientist has to date collected a total of 23 samples, revealing the geologic history of this region of Mars in the process.
One sample called “Lefroy Bay” contains a large quantity of fine-grained silica, a material known to preserve ancient fossils on Earth. Another, “Otis Peak,” holds a significant amount of phosphate, which is often associated with life as we know it. Both of these samples are also rich in carbonate, which can preserve a record of the environmental conditions from when the rock was formed.
Jezero formed from an asteroid impact almost 4 billion years ago. After Perseverance landed in February 2021, the mission team discovered the crater floor is made of igneous rock formed from magma underground or from volcanic activity at the surface. They have since found sandstone and mudstone, signaling the arrival of the first river in the crater hundreds of millions of years later. Above these rocks are salt-rich mudstones, signaling the presence of a shallow lake experiencing evaporation. The team thinks the lake eventually grew as wide as 22 miles (35 kilometers) in diameter and as deep as 100 feet (30 meters).
Later, fast-flowing water carried in boulders from outside Jezero, distributing them atop of the delta and elsewhere in the crater.
A key objective for Perseverance’s mission on Mars is astrobiology, including the search for 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 (broken rock and dust).
Subsequent NASA missions, in cooperation with ESA (European Space Agency), 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.
NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.

The planet Earth has proven to be too limiting for our awesome community of panorama photographers. We're getting an increasing number of submissions that depict locations either not on Earth (like Mars, the Moon, and Outer Space in general) or do not realistically represent a geographic location on Earth (either because they have too many special effects or are computer generated) and hence don't strictly qualify for our Panoramic World project.But many of these panoramas are extremely beautiful or popular of both.So, in order to accommodate our esteemed photographers and the huge audience that they attract to 360Cities with their panoramas, we've created a new section (we call it an "area") called "Out of this World" for panoramas like these.Don't let the fact that these panoramas are being placed at the Earth's South Pole fool you - we had to put them somewhere in order not to interfere with our Panoramic World.Welcome aboard on a journey "Out of this World".
