Bennu asteroid was more active than previously thought
Study of the surface of the asteroid Bennu using the spacecraft's OSIRIS-REx opened the interesting features of this small celestial body. It appears that the object is covered with craters much more than anticipated, as well as loops emits particles which like satellites revolve around the asteroid. On Tuesday said space agency NASA on its website.
The Agency believes that the study of the asteroid Bennu will allow to learn more about the history of the formation of our solar system, because the object may contain material samples, preserved in its original form since the era when our system was very, very young.
"Detection of particle plumes became one of the biggest surprises in my scientific career," - says Dante Lauretta of the University of Arizona in Tucson, is the head of the scientific group dedicated to the analysis of data obtained with the help of scientific instruments onboard the spacecraft OSIRIS-REx.
"The object has a highly rugged, it exceeds all our previous predictions. Bennu has already hit us, and in fact exciting journey has only just begun ", - adds the scientist.
The site space agency NASA indicated that plumes of particles emitted from the surface of the asteroid, the probe were detected OSIRIS-REx with a distance of 1, 61 kilometers of January 6. A team of scientists of the mission decided to increase the frequency of observation of Bennu and within two months was able to witness the emissions of additional particle jets. It is noted that some of these moons around the asteroid and returned to the surface. In any case, the researchers carried out an inspection, making sure the cables do not pose any danger to the spacecraft. Scientists say high performance spacecraft OSIRIS-Rex and are confident that he will be able to respond to an even greater number of available questions when he returns back to Earth in 2023.
"It's only the first three months since the start of a close acquaintance with the asteroid Bennu, but they have already managed to remind us what it is - surprising new discoveries, to make decisions quickly and to adapt to certain conditions", - says Lori Glaze, Acting Division Director planetology in NASA.
"We are studying the asteroids like Bennu in order to better understand the history of our solar system. Spacecraft OSIRIS-Rex will help us answer some very important questions related to the fact, where did we come from. "
Earlier, NASA turned to space enthusiasts with a request to help the mapping of stones on the surface of the asteroid Bennu.
