the Us space administration nasa’s Osiris-Rex spacecraft has found the water Bennu asteroid, Nasa says.
in September two years ago launched a probe reached its destination 3. December. Osiris-Rex will travel 2.2 million kilometres to end up just a few miles from the space traversed by the block block. Now the probe makes closest pass of its seven miles.
Bennu has a diameter of approximately 500 meters. It orbits the Sun at about 160 million miles away. It is classified as a potentially hazardous asteroid, as it is calculated to pass the Earth very close to for about 150 years.
Checking after a probe will be tasked with approaching the asteroid further and join it in orbit in late December. In the first stage of the probe to rotate the asteroid starting at only 1.4 km distance. The ultimate goal is to grab a sample of the asteroid’s surface and bring it back to earth in 2023.
Nasa says that the probe of the spectrometer with the help of found Bennun surface of the clay of the anti-corruption hydroksiileja, i.e. molecules, which together with the oxygen and hydrogen atoms.
the Discovery suggests that asteroids of rock has sometimes been in contact with water. Bennu itself is too tiny that it would contain water in its liquid form. The liquid is believed to have been a bigger asteroid, where Bennu has been chipped.

Bennu is an old old asteroid, so hydroksiilien finding there is Nasa, a real stroke of luck.
– When the probe will bring samples to Earth, scientists can get their hands on the real treasure, providing new information about our solar system the evolution and history of, say, Amy Simon Nasa Goddard space flight center.
Osiris-rex, I still need to measure the asteroid , so that the researchers could determine its mass. This is necessary where the probe can be eventually controlled to very close. Finally, it picks up the asteroid from the surface of the robot arm with the help of a small sample. So far all has gone according to plan.
Preliminary data show that we selected the right asteroid for the Osiris-Rex target. Bennun has not been found insurmountable problem, tell project at the university of Arizona to study the Dante Lauretta .
– the Probe is ok and the devices work better than those required. It’s time to start the adventure.
