NASA is scheduled to land its Perseverance rover and Ingenuity helicopter on Mars in the present day (Feb. 18) and the company selected the right spot for a landing: Jezero Crater.
Jezero Crater is situated within the so-called Isidis Planitia area, simply north of the equator within the jap hemisphere of Mars. This flat plain is situated inside an enormous 750-mile-wide (1,200 kilometers) basin that was carved out three billion to four billion years in the past when a comet or huge asteroid slammed into the Purple Planet. A smaller meteorite, a while later, created Jezero inside this bigger influence basin. Proof suggests a river as soon as flowed into Jezero, the place it shaped a delta that has lengthy since dried up, in accordance with NASA. Right here’s a take a look at Perseverance’s touchdown spot.
You can watch the Mars landing live here and on Area.com’s homepage, courtesy of NASA, starting at 2:15 p.m. EST (1915 GMT). The touchdown is anticipated at three:55 p.m. EST (2055 GMT).

Reside updates: NASA’s Perseverance Mars rover mission
Perseverance follows a line of profitable Martian landings. As an example, the robotic spacecraft referred to as Phoenix landed in a area of Mars’ Vastitas Borealis on Could 25, 2008, and operated till Nov. 2, 2008. That location was the equal of Alaska when it comes to 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 historical delta in Jezero Crater, the place Perseverance will scour for indicators of fossilized microbes. The picture was captured by the Excessive Decision Stereo Digicam onboard the European Area Company’s Mars Categorical orbiter.
Perseverance rover’s Mars touchdown: Everything you need to know
Perseverance has a touchdown goal (white circle) that measures four.eight by four.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 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 seemingly as soon as carved the channels that then carried sediments to kind deltas there. Water, being one of many needed substances for all times, is a promising signal that the rover could uncover fossilized microbes. This picture was taken by devices on NASA’s Mars Reconnaissance Orbiter (MRO).
Photos taken by the Mars Reconnaissance Orbiter Context Digicam have 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 could have seemed like billions of years when it was stuffed with a lake. There was seemingly an inlet and outlet on both facet 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. Actually, 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’re looking for indicators of historical microbial life. To search out these clues, Perseverance will acquire 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 flooring
This indirect view of Jezero appears to be like to the west from above the crater flooring, 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 raise. Scientists hope the identical is true on Mars. The identical mosaic used to generate this view (proven right here) will probably be carried onboard the Mars 2020 spacecraft; will probably be used to assist the craft avoid hazards comparable to cliffs and dune fields on the Martian floor. To create this mosaic, researchers aligned a number of pictures from the Context Digicam on the Mars Reconnaissance Orbiter.
