This was the first for the United States. Only Japan has received asteroid samples.
“I can’t believe we actually pulled it off,” said Dent Lartta, a lead scientist at the University of Arizona. The spacecraft did everything it had to do. ”

Osiris – The Rex spacecraft sent back confirmation of its contact with asteroids more than 200 million miles away, much to the delight of the mission team.
But before scientists know it could be a week, if anything, how much has been caught and whether any further effort is needed. If successful, Osiris-Rex will return samples in 2023.
After sending advance orders through ground controllers near Denver, it took the spacecraft 4 1/2 hours to descend from the narrow orbit around Bannu.
Banu’s gravity was too low for Osiris Rex to land – the asteroid is just 510 meters across. As a result, the spacecraft had to land with its 3.4-meter robotic arm and attempt to capture at least 60 grams of Bannu.
“The amazing thing with this mission is that it performed very well,” he said. He performed in every way. Administrator… https://t.co/snMK489puw

Heather Enos, the mission’s deputy scientist at the University of Arizona, described it as “measuring the length of a long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long, long.” For controllers, wearing royal blue polo shirts and black masks with touch and go-mission patches, the corona virus was delayed by two months due to the epidemic.
Tuesday’s operation was considered the most damaging part of the mission, which began in 2016 with a launch from Cape Canaveral.
A van-sized spacecraft with a mesmerizing name, Osiris-Rex aims to be the equivalent of some parking spaces on the ground in the middle of an asteroid’s Nightingale crater. After orbiting Bannu for about two years, the spacecraft discovered that it lacked the largest patch of particles that could be swallowed.
After determining that the beach was clear, Osiris Rex closed for the last few meters for sampling. The spacecraft was programmed to stir the nitrogen gas that was pressing the surface of the spacecraft, then suck any loose gravel or dust. Communication was expected to last only 5 to 10 seconds after the spacecraft retreated rapidly.
Congratulations to the entire OSIRISREx team and all NASA partners on this mission! We are on the way to rate 4. https://t.co/6lKzMcrxwm

By the time flight controllers heard back from Osiris-Rex, the operation had already taken place 18/2 minutes ago, it took time to pick up radio signals to travel all the way between Bannu and Earth.
Scientists want Bannu’s black, dizzy, carbon-rich between 2 bonuses (60 grams) and 4 pounds (2 kilograms). Our solar system is thought to consist of buildings. “Something that tells the history of our entire planet, the solar system, over the last billions of years,” said Thomas Zarbochen, head of NASA’s science mission. Another advantage: at the end of the next century, binoculars have a slight chance of breaking the earth, although this is not a life-threatening show. The more scientists know about the routes and properties of such potentially dangerous space rocks, the safer we are. Everything will be done
Osiris-Rex can do three touch and go exercises in short. No matter how much effort is put into it, the specimens will not return to Earth until 2023 to end the struggle for more than 800 800 million. The sample capsule will parachute into the Utah desert.
“It simply came to our notice then. But right now it’s the mission’s biggest event, said NASA scientist Lucy Lim.
Japan is expected to land in the Australian Desert in December with its second asteroid mission – at a maximum of milligrams.
Meanwhile, NASA plans to launch three more asteroid missions in the next two years, all one-way trips.
