HOUSTON – A U.s. probe is Monday, arrived at his destination, a rock that is in orbit around the sun, and with a possible impact on our earth, a major disaster can cause.

OSIRIS-REx, the asteroid Bennu in the coming years of study. From all corners of the rock photographed and measured.
These measurements are the preparations for the climax of the mission, which in 2020 should follow. The OSIRIS-REx a few feet above the asteroid go flying, and a kind of vacuum cleaner lowering. That should be a part of the surface vacuum. Then he returns to the earth, and in 2023, he must here countries. Scientists can asteroïdestof yourself under their microscope study. So they want to get a better picture of the origins of our solar system.
The OSIRIS-REx in 2016 launched and now has over 2 billion miles. The mission will cost around 1 billion dollars.
The rock Bennu runs in approximately the same orbit as the earth around the sun, but at about 120 million miles away. He is approximately 500 metres in diameter, as big as a skyscraper. There is a small chance that it will end next century, bringing on the earth. He is too small to be the planet and humanity as a whole to destroy, but it can cause a lot of damage.
According to missieleider Dante she now will impact more than seventy times as much energy is released when the atom bombs on Hiroshima and Nagasaki, and three times as much as the total of all the nuclear weapons ever detonated.
Bennu makes a crater 4 miles in diameter and about a kilometer deep. After the blast creates a pressure wave with a speed of nearly 6,000 miles per hour spreads. The debris may be hundreds of kilometres further to reach. And as the Bennu in the sea ends up, created a tsunami with waves from 28 to 56 metres high.
