NASA is scheduled to land its Perseverance rover and Ingenuity helicopter on Mars right this moment (Feb. 18) and the company selected the proper spot for a landing: Jezero Crater.Â
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 3 billion to 4 billion years in the past when a comet or large asteroid slammed into the Red Planet. A smaller meteorite, a while later, created Jezero inside this bigger influence basin. Evidence suggests a river as soon as flowed into Jezero, the place it shaped a delta that has lengthy since dried up, based on NASA. Here’s a take a look at Perseverance’s touchdown spot.
You can watch the Mars landing live here and on Space.com’s homepage, courtesy of NASA, starting at 2:15 p.m. EST (1915 GMT). The touchdown is predicted at 3:55 p.m. EST (2055 GMT).Â

Not alone
Perseverance follows a line of profitable Martian landings. For occasion, the robotic spacecraft referred to as Phoenix landed in a area of Mars’ Vastitas Borealis on May 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.
Ancient delta
Here, the stays of an historical delta in Jezero Crater, the place Perseverance will scour for indicators of fossilized microbes. The picture was captured by the High Resolution Stereo Camera onboard the European Space Agency’s Mars Express orbiter.Â
Perseverance rover’s Mars touchdown: Everything you need to knowÂ
Ancient lake
Perseverance has a touchdown goal (white circle) that measures 4.8 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. Once upon a time, Jezero was a lake that was a number of hundred ft deep.
Clays and carbonates
Scientists selecting the spot for the Perseverance touchdown knew that Jezero incorporates sediments with clays and carbonates — proof that water seemingly as soon as carved the channels that then carried sediments to kind 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).
Mars mosaic
Images taken by the Mars Reconnaissance Orbiter Context Camera had been put collectively to create this high-resolution mosaic of Mars’ Jezero Crater.
Extreme close-up
This close-up slice of Jezero crater reveals the sweetness and intricacies of the basin on Mars.
Long-ago lake
In this illustration, you may see what Jezero Crater might have appeared like billions of years when it was full of a lake. There was seemingly an inlet and outlet on both facet of the lake. Once the rover has landed, Perseverance will take samples to assist scientists perceive the planet’s geology and previous local weather. In truth, this would be the first mission to gather and save rocks and regolith from Mars.
Circle marks the spot
The NASA crew is focusing on a sure space in Jezero Crater (blue ellipse) for touchdown. They selected the situation with the mission of Perseverance in thoughts: They are looking for indicators of historical microbial life. To discover these clues, Perseverance will acquire samples of rock and regolith, or damaged rock and mud. NASA
Where 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 seems to be to the west from above the crater ground, over the fan-shaped delta and into the valley that cuts by way of the crater rim. On Earth, such deltas usually focus and protect proof of elevate. Scientists hope the identical is true on Mars. The identical mosaic used to generate this view (proven right here) will likely be carried onboard the Mars 2020 spacecraft; it is going to be used to assist the craft avoid hazards equivalent to cliffs and dune fields on the Martian floor. To create this mosaic, researchers aligned a number of photographs from the Context Camera on the Mars Reconnaissance Orbiter.
