Two pounds of asteroids are returning to Earth


Researchers affirm the risks that come NASA The OSIRIS-REx spacecraft on an asteroid a month ago discovered new experiences in the free-shaking structure that can cover the surfaces of numerous small planetary bodies, material that is more comparable to a ball pit in a play area than a solid bedrock. A robotic arm was then able to grab a champion of rock and dust (see these great images of the procedure) before the spacecraft quickly pulled away from the asteroid. And after a four-hour descent, at an altitude of about 410 feet (125 meters), the spacecraft carried out the “Checkpoint” fire, the first of two maneuvers to allow it to precisely address the sample collection site, known as “Nightingale”. NASA discovered the dead end of the device in the images received from the team controlling the spacecraft. According to the space agency, the blockade caused some asteroids to escape into space.

In this unpredictable image provided by NASA, a model container orbits a capsule on the Osiris-Rex probe near the asteroid Pennu. The robotic spacecraft has finally collected all the dust and pebbles from the surface.

“Time Of essence, “Thomas Surbuchen told reporters about the change of plans.” He is associate director of science at NASA.

The process required them to review the images and telemetry of each step to confirm success before moving on to the next step. Some space rock particles were evident moving away from the assortment chamber, prompting supervisors to order the shuttle to place the sample head inside its container back to Earth earlier than expected, limiting the loss of examples.

Bennu and OSIRIS-REx are now millions of kilometers away, so it will take some time for the probe to return home. For this reason, the archiving process should have taken several days.

In March 2021, Osiris-Rex will begin his long journey back to Earth. Scientists said prior to launch and landing on October 20 that the spacecraft could have collected a lot and evidence suggests it probably would have samples of planets that weigh 2.2 pounds or more than 1 kilogram, the university’s mission said.

“Thermal analysis shows that numerous materials on the Bennu surface, notably the large black hummoky rocks, which are the main constituents of the surface, appear to have material properties that do not damage themselves through the atmosphere,” Lauretta She said.

“I am very grateful that our team has worked so hard to achieve this result sample stowed as fast as they did, “said the University of Arizona, Tucson, principal investigator of OSIRIS-REx Dante Lauretta. “As you can imagine, this is difficult.”

Team members also considered making another collection effort.

“They often use black and white photos for sharper details, but in this case I’m pretty sure Bennu is indeed dark gray and this coloring is wrong,” said another user adding that OSIRIS-REx has at least one colored camera as shown. color images of the Earth during type C. asteroid overflight. The flight will last two and a half years, with the spacecraft’s expected arrival date set for September 2023.

Being so close to the Earth, NASA designated on asteroid as an object near the Earth (NEO). Japan is the only other country that has it. He was successfully captured this way sample.

Bennu has remained mostly unchanged since the formation of the universe and we will have enough many teams to run many tests that will no doubt teach us a lot about the first solar system. NASA he chose to collect a champion by Benz because it is believed to contain carbon-rich material It is protected Building modules of our solar system.
