NASA is scheduled to land its Perseverance rover and Ingenuity helicopter on Mars right now (Feb. 18) and the company selected the proper spot for a landing: Jezero Crater.
Jezero Crater is positioned within the so-called Isidis Planitia area, simply north of the equator within the japanese hemisphere of Mars. This flat plain is positioned inside an enormous 750-mile-wide (1,200 kilometers) basin that was carved out 3 billion to 4 billion years in the past when a comet or massive 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, where it shaped a delta that has lengthy since dried up, in line with NASA. Here’s a take a look at Perseverance’s touchdown spot.
You can watch the Mars touchdown reside right here and on Space.com’s homepage, courtesy of NASA, starting at 2:15 p.m. EST (1915 GMT). The touchdown is anticipated at 3:55 p.m. EST (2055 GMT).

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 in phrases of latitude. Then, on July 20, 1976, Viking 1 it turned 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 historic delta in Jezero Crater, where 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.
Perseverance rover’s Mars touchdown: Everything you must know
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 may 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 accommodates sediments with clays and carbonates — proof that water probably as soon as carved the channels that then carried sediments to type deltas there. Water, being one of the mandatory elements 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 have 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 wonder and intricacies of the basin on Mars.
Long-ago lake
In this illustration, you possibly can see what Jezero Crater might have seemed like billions of years when it was full of a lake. There was probably an inlet and outlet on both aspect 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 reality, this will be the primary 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 historic microbial life. To discover these clues, Perseverance will accumulate samples of rock and regolith, or damaged rock and mud. NASA
Where on Mars?
Jezero Crater is positioned simply above the Martian equator within the planet’s easter hemisphere.
From the crater flooring
This indirect view of Jezero seems to the west from above the crater flooring, over the fan-shaped delta and into the valley that cuts via the crater rim. On Earth, such deltas typically focus and protect proof of raise. Scientists hope the identical is true on Mars. The similar mosaic used to generate this view (proven right here) will be carried onboard the Mars 2020 spacecraft; it will be used to assist the craft steer clear of hazards akin 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.
