Jezero Crater is situated within the so-called Isidis Planitia area, simply north of the equator within the japanese hemisphere of Mars. This flat plain is situated inside a large 750-mile-wide (1,200 kilometers) basin that was carved out Three billion to Four billion years in the past when a comet or large asteroid slammed into the Pink Planet. A smaller meteorite, a while later, created Jezero inside this bigger impression basin. Proof suggests a river as soon as flowed into Jezero, the place it shaped a delta that has lengthy since dried up, based on NASA. Right here’s a have a look at Perseverance’s touchdown spot.

Reside updates: NASA’s Perseverance Mars rover mission
Perseverance follows a line of profitable Martian landings. As an illustration, the robotic spacecraft known as Phoenix landed in a area of Mars’ Vastitas Borealis on Might 25, 2008, and operated till Nov. 2, 2008. That location was the equal of Alaska by way of latitude. Then, on July 20, 1976, Viking 1 it grew to become the second spacecraft to land on Mars. It was additionally the primary lander to finish its mission efficiently.
Right here, the stays of an historic delta in Jezero Crater, the place Perseverance will scour for indicators of fossilized microbes. The picture was captured by the Excessive Decision Stereo Digital camera onboard the European House Company’s Mars Categorical orbiter.
Perseverance rover’s Mars touchdown: Every little thing you want to know
Perseverance has a touchdown goal (white circle) that measures 4.eight by 4.1 miles (7.7 kilometers by 6.6 kilometers) in diameter inside Jezero Crater. The crater’s fan-shaped delta and rim could be seen on this picture. As soon as upon a time, Jezero was a lake that was a number of hundred toes deep.
Clays and carbonates
Scientists selecting the spot for the Perseverance touchdown knew that Jezero comprises sediments with clays and carbonates — proof that water doubtless as soon as carved the channels that then carried sediments to type deltas there. Water, being one of many crucial substances for all times, is a promising signal that the rover might uncover fossilized microbes. This picture was taken by devices on NASA’s Mars Reconnaissance Orbiter (MRO).
Pictures taken by the Mars Reconnaissance Orbiter Context Digital camera had been put collectively to create this high-resolution mosaic of Mars’ Jezero Crater.
This close-up slice of Jezero crater reveals the sweetness and intricacies of the basin on Mars.
On this illustration, you possibly can see what Jezero Crater might have appeared like billions of years when it was stuffed with a lake. There was doubtless an inlet and outlet on both aspect of the lake. As soon as the rover has landed, Perseverance will take samples to assist scientists perceive the planet’s geology and previous local weather. In reality, this would be the first mission to gather and save rocks and regolith from Mars.
Circle marks the spot
The NASA workforce is concentrating on a sure space in Jezero Crater (blue ellipse) for touchdown. They selected the situation with the mission of Perseverance in thoughts: They’re searching for indicators of historic microbial life. To seek out these clues, Perseverance will gather samples of rock and regolith, or damaged rock and mud. NASA
The place on Mars?
Jezero Crater is situated simply above the Martian equator within the planet’s easter hemisphere.
From the crater ground
This indirect view of Jezero appears to be like to the west from above the crater ground, over the fan-shaped delta and into the valley that cuts by the crater rim. On Earth, such deltas typically focus and protect proof of carry. Scientists hope the identical is true on Mars. The identical mosaic used to generate this view (proven right here) shall be carried onboard the Mars 2020 spacecraft; will probably be used to assist the craft keep away from hazards comparable to cliffs and dune fields on the Martian floor. To create this mosaic, researchers aligned a number of photographs from the Context Digital camera on the Mars Reconnaissance Orbiter.
