The OSIRIS-REx spacecraft has been detected by NASA for a close proximity of the physical asteroid water, which is common with the shape of an acorn that can survive to life sources on Earth, saying science.
OSIRIS-REx, which included the week within a 19km shade of the asteroid. Determines about 2.25 million kilometers from Earth, detecting signs of hydrids and oxygen – part of the trap for water and so Capacity for life – based on rocky surface of the asteroid S-
The study, launched a mission to remove samples from the asteroid to Earth for inspection, was launched in 2016.
Bennu, about 500 meters wide, will affect its & # 39; sun near the same distance as Earth. There is a concern among scientists about the ability that Bennu a & # 39; affecting Earth in the late 22nd century.
"We got full-of-the-art minerals from the early solar system, and that's just the kind of sample we were going to find and bring back to Earth", a rural scientist University of Arizona, Dante Lauretta, the mission of OSIRIS-REx said a chief inspector in a telephone interview.
Asteroids are among the remaining debris created by the solar system for around 4.5 billion years ago.
Scientists believe that asteroids and comets can be used. rapidly falling the Earth to deliver organic and organic merchandise and inherited water; planet for life, and atomic level analysis of a sample from Determining specific evidence can be provided to support that view.
"When its mission to Earth returns in 2023 with samples of this material, scientists will find an inventory of new information on the history and development of our solar system," Amy Simon, Scientist at Space Space Conduct Center in Maryland, she said in a statement.
"We are very much trying to recognize the role of these rich, asteroids of coal in delivering water to Earth early and adapting it," said Lauretta.
OSIRIS-REx will pass longer on & # 39; This month is just 1.9km from Bennu, entering the important asteroid pull and its; explore her. From then on, the spacecraft will begin to slow the orbit around the asteroid gradually, and then; moving to two meters of surface so the army can robot a sample of Determination before July 2020.
The spacecraft will be further back to the Earth, which completes a capsule that goes to the Earth; describes the asteroid for a parachute climb in the Utah desert in September 2023.
