NASA’s Osiris-Rex robot probe has completed its two-year, two billion-mile journey to the skyscraper-sized Bennu asteroid in what could prove to be one of the Agency’s most important missions yet.
Just one week after NASA landed a spacecraft on Mars, the Osiris-Rex ship’s mileage showed 1.2 miles. It completed the journey with a 20-second burner combustion to arrive within 12 miles (19 km) of the diameter with a diameter of 500 meters, diamond-shaped space rock. The excited reactions of the staff in mission control were captured on film; the culmination of a decade’s work.
“My heart rate is three times faster than usual, but I’m very excited. Looking at the team that celebrates such an amazing milestone gives me personal joy in so many ways that I can not even explain,” Heather Enos, Osiris-Rex Deputy Chief Researcher said about the important occasion.
Osiris-Rex, responsible for Origins, Spectral Interpretation, Resource Identification, Security-Regolith EXplorer, began its trip in 201
6 with a launch from Cape Canaveral, Florida.
The project’s $ 800 million probe task is monumental in scale and weight. The NASA team aims to determine whether the potentially dangerous asteroid is actually on course to influence the earth and how we can deflect or destroy it if it is.
“But this is all dependent on the outcome of a very close approach that Bennu has with the earth in September 2135,” Lindley Johnson, a planetary defense officer with the Nasda Research Research Center for Science, said, cited by telegraph
We just have to wait and see. Rather, our grandchildren will see.
There is apparently a one-in-2,700 chance that Bennu will hit the ground in 166 years, placing Bennu at number two in NASA’s ranking of 72 potentially dangerous Near Earth Objects (NEO).
In addition, researchers hope that the mission will provide more information about the source of both water and life in our own solar system. Finally, the mission will also provide more insights into the overwhelming potential of asteroid recovery in the future.
The mission marks the first attempt from a US craft to successfully land on an asteroid after Japan’s recent success with the Ryugu asteroid, which is about twice as big as Bennu.
The Osiris-Rex mission is one of the most ambitious asteroid investigations so far, which aims to restore between 60 grams (two ounces) and two kilograms regolith and gravel from the Earth’s asteroid), the most extraterrestrial material collected since the Apollo mission landed on the moon.
To achieve this, the craft will establish a progressively faster course through a spiral down to a distance of about six meters for its recurring mission sometime in July 2020. The probe will extend its three-meter robot arm to give the asteroid a ” high five “and blast it with pressurized gas to kick

This will be made more difficult because The heat of the sun will change the craft path slightly, which means that mission control on earth must take care to issue course corrections and keep the probe in place before it can establish a stable circulation in early 2019.
Current estimates show that spacecraft could cross the ground and the moon 2135 and possibly even closer between 2175 and 2195, but preliminary findings on the composition of spacecraft and runway b is warned of being announced Monday at the American Geophysical Union (AGU) meeting in Washington DC.
