NASA proves to find water signs on Determining an asteroid nearby

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.

Main points:

  • NASA OSIRIS-REx spacecraft detected signs of hydrogen and oxygen on the Binding asteroid
  • Asteroids and comrades that fall to Earth early may have transported companies that have influenced life
  • OSIRIS-REx generates specimens from Bennu and then returns to Earth in 2023

OSIRIS-REx, which included the week within a 19-inch shadow of the Asteroid Detection, which is approximately 2.25 million kilometers from Earth, detects signs of hydrogen and oxygen – part of the trap for water and therefore the ability to create the asteroid rocky surface life.

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 potential for the Determining of the Earth to be late in the 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 really trying to recognize the role of these rich asteroids of coal in delivering water to Earth early and making it live, "said Dr Lauretta.

Later this month, OSIRIS-REx will only pass 1.9 kilometers from Bennu, and & # 39; go into the important asteroid pull and analyze the ground. From then on, the spacecraft will begin to slow its orbit around the asteroid gradually, and then; moving to 2 meters of surface so the army can carry a sample robot of Bennu 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 fire in the Utah, United States desert in September 2023.
