The OSIRIS-REx space probe discovered traces of water on the asteroid Benn explored. This is reported by NASA.

It is noted that the presence of water marks on the asteroid of Bennu is highlighted by the data collected by two spectrometers. OSIRIS-REx automatic station. These devices detected the presence of hydroxyl or water residues.
Experts involved in OSIRIS-REx mission support for the device are suspected of having hydroxyls on the Bennu asteroid everywhere. This means that probably in the past, water was present at a larger astronomical site, from which the asteroid Benn was separated. Experts pointed out that because of the small size of the asteroid itself, there was no liquid water.
What do we know about OSIRIS-REx? The probe was launched in space in September 2016. The device is equipped with a range of devices, including cameras, spectrometers and laser altimeters. The aircraft traveled 2.2 million kilometers and on December 3, 19 kilometers of the asteroid Bennu approached. It is expected that a land capture operation on an asteroid will be carried out later with the aid of a manual manipulator operated by a special pneumatic device. The creators of NASA expect to recover from the surface of the object between 60 grams and 2 kg of soil.
One of the main objectives of this project is to obtain new data on the structure and composition of asteroids that may pose a potential hazard to our planet. Subsequently, this information can be used to organize special missions to prevent the asteroid threat. It is assumed that the soil sample on an asteroid will take the device in mid-2020. And the return to Earth of the probe capsule is scheduled for September 2023.
What do we know about the asteroid Benny? It is classified as a carbonaceous asteroid of spectral class B. These asteroids could be the source of supply of complex organic compounds and water for the young Earth. The orbits of the Earth and Benny intersect – the probability of a collision with our planet is estimated to be between 1,000 and 4,000. On December 10, 2018, NASA reported that "on the surface of the Earth", asteroid, traces of water that may be present in liquid form were found on a larger object from which the asteroid had broken.
