NASA rocket approaches space rock Bennu

OSIRIS-REx is intended to connect with a mechanical arm to "high-five" the surface of the space rock and restore the example to Earth in 2023 

Two years in the wake of propelling from Florida, a NASA rocket is surrounding an old space rock, Bennu, for an example of room dust that could uncover signs to the beginning of life in the nearby planetary group. 

The rocket, OSIRIS-REx — Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer — has even snapped its first, foggy photo of the infinite body, which is about the span of a little mountain, around 500 meters in measurement. The shuttle is intended to circle Bennu and connect with a mechanical arm to "high-five" its surface, at that point restore the example it gathers to Earth in 2023.

The primary pictures of Bennu were gone up against August 17 at a separation of 2.3 million kilometers from the $800 million rocket. "This is the nearest we have even been to Bennu," said Dante Lauretta, OSIRIS-REx central agent at the University of Arizona, Tucson. "This is critical in that we are currently in the region of the space rock, closer than we have ever been notwithstanding amid the nearby methodologies of the space rock to the Earth." 

Carbon-rich space rock 

Bennu was browsed the somewhere in the range of 500,000 space rocks in the nearby planetary group since it circles near Earth's way around the sun, it is the correct size for logical examination, and is one of the most established space rocks known to NASA. Space experts say it represents a slight hazard — a one out of 2,700 shot — of crashing into Earth in 2135. 

It is additionally a carbon-rich space rock, the sort of infinite body that may have conveyed nurturing materials to Earth billions of years back. The OSIRIS-REx mission isn't the first to ever visit a space rock and endeavor an example return — Japan has done it previously and Europe has figured out how to arrive on a comet. Yet, it is the principal space rock test return mission for NASA, and it means to bring back the greatest example ever, at the request of 60 grams. 

In December, the shuttle will start a point by point study of space rock's surface, which NASA has characterized as "landing" at the space rock. An orbital addition is normal on December 31. The example, be that as it may, won't be taken until July 2020.
