NASA's Osiris Rex robot probe has completed its two-year, two-billion-kilometer journey to a skyscraper-sized asteroid at Bennu, which may turn out to be one of the agency's most important tasks.
Exactly a week after NASA landed a spacecraft on Mars, the Oscillator of the Osiris Rex aircraft showed kilometers of 1.2 billion kilometers. He completed the journey with a 20-second engine fire to reach within 19 kilometers of the diamond-shaped space rock with a diameter of 500 meters. The enthusiastic reactions of the mission control staff were recorded on film. the culmination of a decade's work.
"My heart rate is three times faster than normal, but I'm so excited. Seeing the team celebrating such an amazing milestone brings me so much personal joy that I can not even explain it, "said Heather Enos, deputy chief investigator for Osiris-Rex, about the momentous opportunity.
Osiris-Rex, which stands for Origins, Spectral Interpretation, Resource Identification and Security Regolith Explorer, began its journey in 201
The mission of the $ 800 million probe is enormous and of great importance. The NASA team wants to find out if the potentially dangerous asteroid is actually affecting the earth and how we could possibly distract or destroy it if it does.
"But that all depends on the outcome of a very close rapprochement that Bennu undertook with Earth in September 2135. Lindley Johnson, a planetary defense officer at Nasa's science mission directorate, said, as quoted by the Telegraph.
We just have to wait. Rather, our great-great-grandchildren must see grandchildren.
There is a supposed chance that Bennu will hit Earth in 166 years, placing him second in the NASA ranking of 72 potentially dangerous Earth Objects (NEOs).
In addition, the scientists hope the mission will provide more information about the source of water and life itself in our own solar system. Finally, the mission will provide further insights into the amazing potential of asteroid mining in the future.
The mission marks the first attempt by a US aircraft to land successfully on an asteroid after Japan's recent success with the Ryugu asteroid. This is about twice the size of Bennu.
The Osiris Rex mission is one of the most ambitious asteroid investigations to yield between 60 grams (two ounces) and two kilograms of regolith (dust and gravel from the topsoil) the asteroid), the most extraterrestrial material retrieved on the moon since the Apollo mission.
To accomplish this, the ship will make a gradual denser orbit through spirals. The probe will extend its three-meter-long robot arm to give the asteroid a "high five" and blow it up with pressurized gas, then screeching it up sterile storage chamber is collected.

more difficult as the heat of the sun will slightly alter the trajectory of the aircraft means that the mission control must be closely monitored again on Earth to make course corrections and to keep the probe in place before it can establish a stable orbit in early 2019.
Current estimates indicate that space rock could pass between the Earth and the Moon in 2135, possibly approaching between 2175 and 2195, although preliminary findings on the composition and trajectory of space rock were released Monday at the American Geophysical Union AGU Meeting in Washington DC
