Asteroid Bennu, which will be able to provide answers to questions about the origins of our solar system, is in a mysterious way, with the launch of particles into space, and NASA is not sure why.
Since the reach of the massive space rock in December of 2018, NASA has observed in multi-particle ejection events, including the three most important points in the Jan. 6), Jan. 19 Feb. 11. The researchers found that the particles are either centred on Bennu, and fell back to the surface, or is escaping his job, and went into the room. In the main event, which took place on Jan. 6, he saw “about 200 particles get ejected from the asteroid, which NASA wrote in a blog post.
The particles have traveled as fast as 10 feet and ranged in size from less than an inch to 4 inches. The mysterious is ejected, it may be caused by three reasons, according to a NASA blog post: meteorite impacts, and thermal stress will break, and the released water vapor.
In this view of the asteroid Bennu to eject particles from the surface at the Jan. 6, 2019, has been created by combining two images taken by the NavCam is 1 of the imager on board of NASA’s OSIRIS-REx spacecraft: a short-exposure images, which show the asteroid clearly, and in a long-exposure image (five seconds), in which the particles are clearly evident.

THE SECOND INTER-STELLAR VISITORS TO THE WATER OUTSIDE OF OUR SOLAR SYSTEM, DISTURBING STUDY SUGGESTS
Meteorite impacts are common in the “deep space area” of the Bennu, NASA added, noting that it is possible for this to occur, when the space agency’s craft, the OSIRIS-REx has been a failure to comply with it.
The thermal break may also have a role to play, due to the large change in the temperature of Bennu’s experiences during the 4.3 hour rotation period. The surface of the asteroid “that heats up considerably during the middle of the afternoon, which is when the us said that the largest particle ejection events have taken place, leading to the theory that the temperature of the causes the rocks to crack, break, and get out.
In December 2018, NASA discovered that there was water in the clay is that it can also make sure that the particles are removed when water is heated and the pressure increases.
The particulate emissions can also be a combination of all three methods), Steve Chesley, and the study’s lead author pointed out to us. “It is possible that more than one of these possible mechanisms may play a role in this,” Chesley said in a blog post. For example, the thermal fraction can be cut from the material of the surface into smaller pieces, which makes it a lot easier for a meteorite impact prior to the launch of pebbles in the room.”
NASA posted a video on their YouTube page, adding more details about the particulate emissions.

“Under the Bennu, the many surprises of the particulate emissions and aroused our curiosity, and we have spent the last month researching this mystery,” said Dante, she now, OSIRIS-REx principal investigator from the University of Arizona in Tucson. “This is a great opportunity to expand our knowledge of how asteroids behave.”
OSIRIS-REx stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer, which was launched in September 2016 from Cape Canaveral Air Force Station. It carries five data-taking tools, and it is the intention to return with samples of the asteroid in September 2023.
