KYIV. December 3 UNN OSIRIS-REx, US interplanetary, will fly Monday to the asteroid of Bennet, which he should study the surface over the next two years. The United States National Administration for Aeronautics and Space (NASA) has indicated on its Twitter page that UNN .
"Tomorrow, our OSIRIS-REx will meet the near-Earth asteroid, Benn! He will study Bennu more than two years before collecting and sending a sample (ground) to Earth," says the message.
The spacecraft was launched in space on September 8, 2016. In September of this year, he began his first research on dust emissions around Bennu in order to calculate the safety trajectory of the engine. approaching the station towards the asteroid.
The device is equipped with several devices, including cameras, spectrometers and a laser range finder. OSIRIS-REx will launch a systematic study and mapping of the surface of the asteroid. Based on the data received, experts will choose a site for landfill, which should be set up in mid-2020 without landing with a manual manipulator equipped with a special pneumatic device. NASA is hoping to collect up to 2 kg of dust and soil that should carry a special capsule to Earth in September 2023.
Tomorrow's Day for Our @OSIRISREx Meeting the spacecraft with the quasi-terrestrial asteroid Bennu! He will study Bennu for more than two years before collecting and returning a sample to Earth.

According to scientists, studying Benn's soil will help to better understand how the formation of the solar system unfolds. Another objective of the project – to obtain new data on the structure and composition of asteroids, representing a potential danger for the Earth. Subsequently, this information can be used to prevent an asteroid threat.
Bennus, spinning in an elliptical orbit around the Sun, with a diameter of about 550 m, was discovered in September 1999. Astronomers attribute it to Apollo – the asteroids, whose orbits cross the planet. Orbit of the Earth. The probability of collision with him is from 1 to 4000, and some experts do not rule out that this can happen at the end of the 21st century. The fall of an asteroid of this size on our planet would be equivalent to an explosion of 2700 megatons in a TNT.
