NASA sees 'otherworldly' wreckage on Mars with Ingenuity helicopter


in article 1

The item appears to be like like a flying saucer that crashed on Mars.

And it’s certainly the case.

However it doesn’t belong to the extraterrestrials.

As an alternative, the wreckage is the work of NASA, a part known as a backshell that broke off throughout the landing of the Perseverance rover on the floor of the pink planet in February 2021.

“There’s undoubtedly a science fiction component to it,” Ian Clark, an engineer who labored on Perseverance’s parachute system, mentioned of the images launched Wednesday. “It breathes the opposite world, doesn’t it?”

On its twenty sixth flight final week, Ingenuity took 10 photographs throughout its 159 seconds within the air masking 1,181 toes. These present that the again shell, or high half of the touchdown pod which protected Perseverance and Ingenuity as they plunged via the Martian environment. The 70-foot-wide parachute that slowed the automobiles’ descent continues to be hooked up.

The parachute and rear shell separated from the rover at an altitude of 1.3 miles. A rocket-propelled system known as Skycrane carried Perseverance to the floor, whereas the rear hull and parachute landed over a mile to the northwest.

The rear hull, almost 15 toes in diameter, hit the bottom at about 78 miles per hour, partially breaking up. In any other case, all the things seems to be in good situation – no apparent indicators of charring. The parachute seems to be intact, as are the strains connecting the parachute to the again shell. However engineers have solely simply begun to scrutinize the brand new photographs intimately.

“They are saying an image is price 1,000 phrases, however it’s additionally price an countless quantity of technical data,” Clark mentioned.

Learning the stays of the again shell may show helpful for NASA’s subsequent huge Mars journey – bringing rocks and soil from Mars again to Earth for extra detailed research. This mission, known as Mars Sample Returnshould put two landers on the floor – a rover to gather rock samples drilled by Perseveranceand a small rocket to launch the samples into orbit for one more spacecraft to select up and return to Earth.

“We use all of our greatest fashions, all of our greatest analytical instruments,” Clark mentioned. The photographs assist confirm that the fashions and evaluation are working correctly, which provides confidence to the fashions sooner or later.

Kenneth Farley, the mission’s challenge scientist, was fascinated not solely by the “actually spectacular” photographs of the fabric, but in addition by what the fabric landed on.

“Remarkably, this wreckage ended up simply touching the 2 rock formations on the backside of the crater,” Dr Farley mentioned in an electronic mail. The 2 formations, named Seitah and Maaz, are each made up of volcanic rocks. However their composition could be very completely different. Seitah is wealthy in olivine which was deposited from thick magma, presumably a lava lake. Maaz, which is on the high and due to this fact in all probability youthful, has a composition just like most basalt lava flows – filled with minerals often known as pyroxene and plagioclase however with little or no olivine.

The 2 formations meet on a line of rocks that runs from the rear hull to an space proper subsequent to the parachute. “We need to understand how these rocks would possibly relate to one another,” Dr Farley mentioned.

Mission scientists had been so intrigued by the geology that Ingenuity made one other move over the boundary line between Seitah and Maaz on Sunday. These photographs can be despatched again to Earth on Thursday.

Perseverance additionally took care of his journeys. On April 2, he took a collection of photographs of the small martian moon Phobos passing in entrance of the solar, a partial eclipse by the potato-like object. Detailed measurements of Phobos’ orbit give perception into the inside construction of Mars.
