The first mission of the NASA have to plan for go to the asteroid and bring a sample of your vacuum The Earth arrived at its destination on Monday, Bennu, two years after the launch of Cape Canaveral, Florida.

The $ 800 million mission, known as OSIRIS-REx, have contacted the asteroid at about 12h.m. p.m. (17h.10. GMT), ignoring his machines for the last time.

"We've arrived"said engineer at Lockheed Martin, Javier Cerna, while her mission management colleagues in Littleton, Colorado, welcome and shake their palms, as seen on NASA's live television broadcast.

500 meters in diameter, Determine the size of a small mountain and here is the smallest object that has been orbit by a man's space ship.

Setting, a piece of the initial solar system, is also considered potentially dangerous. It's a small risk, with a potential of 2,700 conflicts with Earth in 2135.

Rich in carbon, it has been chosen of about 500,000 asteroids in the solar system due to Orbit near the Earth circuit around the Sunbecause here is the right size for scientific study and One of the oldest asteroids that is known to NASA.

Scientists hope it will reveal more information about the formation of the solar system at an early stage and how to find valuable resources such as metals and water in asteroids.

"With asteroids, you have a time capsule, you have a pristine sample of what the solar system was like millions of years ago," said spokesman for the NASA Space Goddard Space, Michelle Thaller.

"That's why scientists that this sample will be much more valuable than gold," he said.

A soft shit of five

The mission was launched in September 2016. After several months OSIRIS REx had been approaching Determination and finally reached the space rock when it was almost 129 million kilometers of Earth.

"In recent months, Setting was set in focus as I contacted", says the OSIRIS-REx account on the Twitter network.

"Now I'm here, I'll fly around the asteroid and study precisely," he said.

There is a set of spacecraft space Five scientific tools to study asteroid in the next and half years, mapping it in a high resolution to help scientists decide exactly where to take the sample.

In 2020, the search engine will extend his robotic arm and touch the asteroid with a movement described as "lightweight palms" by Rich Kuhns, director of the OSIRIS-REx program at Lockheed Martin Space Systems in Denver.

Using a circular device similar to a car filter, and an inverse vacuum to collect dust, it aims to collect approximately two acres (60 grams) of surface surface material and to return to the Earth to study further.

NASA said it could have much more material of the asteroid, perhaps more than two gilo.

US space agency heads are hoping to use OSIRIS-REx to bring as many loads as possible from samples since the Apollo period, active in the 1960s and 1970s when collectors and US researchers and carry 382 kilograms to Earth. from gray rocks.

Japan JAXA space agency was the one who first proved that the collection of asteroid samples was possible.

In 2010, Hayabusa's spacecraft was accidental to face its target asteroid and managed to extract a few filigrams of material in 2010.

Once NASA's successful mission has accumulated Space Deposit dust, the sample will be retained and returned to Earth in 2023, when it will be in the Utah desert by the end of September, NASA said.

OSIRIS-REx is the acronym for Origins, Spectrum Interpretation, Resource Recognition, Security Recovery Explorer.
