The National Aeronautics and Space Administration (NASA) shared images of the asteroid Bennu captured from its origin, spectrum interpretation, resource identification, security, and the OSIRIS-REx spacecraft, which is now scheduled to Return to Earth in 2023. , “Stop! A steroid crossing 4.5 billion years ago! You are viewing a real image of the asteroid Bennu captured from @NASASolarSystem’s #OSIRISRex spacecraft.” The agency said that the spacecraft that has been flying in space for nearly five years is now It is returning to Earth, which contains rock and dust samples from ancient cosmic objects.
The photo shows that as OSIRIS-REx moves away from Bennu, the side of Bennu of the crescent moon merges with the dark space. For two years, the spacecraft has studied this asteroid and revealed several secrets of this ancient corpse.
It also helps to further understand its consistency and surface topography similar to gravel piles. NASA said in a note on its website that the terrain of the asteroid is much more rocky than originally expected from ground-based telescopes, and it is rugged.
The spacecraft began its return journey on May 10, 2021, and is expected to abandon the airtight capsule containing the samples, and be sent into orbit on September 24, 2023 to land in the Utah desert. The spacecraft carries more than 60 pieces of dust and debris per gram of the asteroid, and it is the largest sample collected by NASA since the Apollo mission brought back lunar rocks.
To achieve this goal, NASA launched a high-risk operation in October 2020: the probe contacted the asteroid for a few seconds and launched a compressed nitrogen explosion to lift the dust sample and then capture it.
To NASA’s surprise, the probe’s arm sank a few centimeters into the surface of the asteroid, indicating that the scientists “the surface of these gravel asteroids are very loosely reinforced,” mission leader Dante Lauretta (Dante Lauretta) stated in a NASA video broadcast: The spacecraft has begun its return voyage.
A few days later, NASA realized that the valve of the collection module could not be closed, allowing the debris to escape into space, and the entire mission was almost zero.
However, these precious cargoes were finally fixed after being transferred to the space capsule fixed in the center of the spacecraft.
NASA said the samples will be transported to the Johnson Space Center in Houston, and then distributed to laboratories around the world from there, enabling scientists to study the formation of our solar system and the Earth as a habitable planet.
Not only that, the Ace Space Agency also decided to keep 75% of the samples and save them to future generations, who can use technologies that have not yet been invented or developed to study them.
