And if NASA experts are right, OSIRIS-Rex is ready to answer humanity's biggest question – "where did we come from?" Remarkable images released by the US Space Agency show an asteroid measuring 262 meters in size. Using OSIRIS-Rex spacecraft, they tracked the object around the solar system and planned to land on its surface to collect vital samples to return to Earth by 2021.
Scientists believe the spacecraft may have signs of water and organic compounds – referred to as NASA's "hydrated minerals" – and may begin to explain how life on Earth has evolved.
Some scientists have long theorized that life arrived on Earth through an asteroid. What is not known is whether this life has arrived fully formed or whether the asteroid simply contains the building blocks of life. And this is the exciting part of the NASA team.
Bennu has stunned experts for decades and many believe its properties are vital to prove the existence of organic compounds outside the solar system.
Beenu is considered a Type B asteroid and has similar clay properties comparable to the way Earth began millions of years ago.
Scientists also believe that the asteroid may have been part of a much larger object.
It is estimated that the cosmic rock may have collided with another asteroid between 700 million and two billion years ago.
Bashar Rizk, a scientist with tools for OSIRIS-Rex, stressed the importance of the mission for humanity.
Mr Rizk said: "The story of this asteroid is the story of the solar system.
"When we understand we will understand something fundamental about our solar energy system. "
The mission is directed to an example site with a radius of 25 m.
However, such sites do not exist in Bennu and since then NASA has begun exploring 5 to 10 m test areas
of four candidate sample sites. Bennu is designated as a nightingale, bower, spray and sandstone – all birds native to Egypt.
Rich Burns, Project Manager of OSIRIS-REx at NASA Goddard Space Flight Center in Greenbelt, Maryland, says: "Although OSIRIS-REx was designed to collect an asteroid sample with a beach-like area, exceptional time efficiency the flight to date shows that we will be able to meet the challenge posed by Bennu's solid surface.
"This exceptional performance encompasses not only spacecraft and instruments, but also a team that continues to meet every challenge Bennu throws at us. "
Nightingale, the northernmost site, contains many possible sampling regions at this site, which is located in a small crater enclosed by a 459-foot diameter crater.
Kingfisher is located in a small crater 26 feet in diameter near the equator of Benou at 11 degrees north latitude. It is also known to have the strongest spectral signature for hydrated minerals.

A spray is placed slightly larger by a crater 66 feet in diameter, also located in the equator the region of Bennu. Osprey has the strongest spectral feature of carbon-rich material.
Finally, Sandpiper is in a relatively flat area on the wall of a large crater with a diameter of 207 feet.
Hydrated minerals are also present.
Bennu was discovered on September 11, 1999 after an asteroid study near Earth conducted by the asteroid study near Lincoln Earth.
Experts estimate that Bennu is likely to hit 2,700 Earth between 2175 and 2199.
