(ORDO NEWS) — Analysis of photographs of craters on the surface of asteroid Bennu showed that it entered near-earth space about 1.75 million years ago. Japan is the only other country to have accomplished such a feat. NASA will not know how much material it collected until the sample capsule returns in 2023. Shortly after NASA got word from the spacecraft that its arm had touched down safely, Dante Lauretta, a planetary scientist at the University of Arizona and the principal investigator of the mission, said he felt “transcendental, I mean I can’t believe we actually pulled this off. The OSIRIS-REx is expected to remain orbiting Bennu until 2021 and then return to Earth with its samples in 2023. There is a 1-in-2,700 chance of Bennu impacting Earth in the late 2100s. Asteroids are among the leftover debris from the solar system's formation some 4.5 billion years ago. Post was not sent - check your email addresses! The leakage had the OSIRIS-REx mission team scrambling to stow the collection device to prevent additional spillage. It is a type of asteroid known as a carbonaceous chondrite, which is thought to be rich in the building blocks of life such as carbon and water. A sample could hold clues to the origins of life on Earth, scientists say. “We calculated how many small craters with a diameter of 50 cm or less on Bennu’s surface. “These asteroids are really relics of the earliest material that formed the planets in the solar system,” Lori Glaze, NASA’s planetary science division director, told reporters Monday. There is also a very slim chance Bennu may hit Earth in about 150 years. 63,431, This story has been shared 58,651 times. © 2020 NYP Holdings, Inc.

"The loss of mass is of concern to me, so I'm strongly encouraging the team to stow this precious sample as quickly as possible," he said.
