Bennu 's Journey.
This will be key to the next stage of the mission- Bennu's approach and sampling.
Bennu's experiences will tell us more about where our solar system came from and how it evolved.
NASA is still working on chemical analysis of Bennu's surface, which would provide firmer answers.
Bennu's orbit takes the space rock as close as 0.9 astronomical units, or AU, to the sun, and as far away as 1.36 AU.
Some move at up to 7 mph(11 km/h),fast enough to escape Bennu's weak gravity and cruise into interplanetary space.
Knowing Bennu's physical properties will be critical for future scientists to understand when developing an asteroid impact avoidance mission.[35].
The $1 billion OSIRIS-REx mission was launched in September 2016 andreached reached Bennu's immediate vicinity on 3 December.
But such was the case for Bennu's“parental body”, which was probably a much larger asteroid that has collapsed.
The original mission design called for OSIRIS-REx to sample material from a relatively smooth,flat patch of Bennu's surface at least 165 feet(50 m) wide.
Astronomers have calculated that Bennu's orbit has drifted about 280 meters(0.18 miles) per year toward the Sun since it was discovered.
Unlike most other asteroids that circle the Sun in the asteroid belt between Mars and Jupiter, Bennu's orbit is close in proximity to Earth's, even crossing it.
We won't know for sure where Bennu's diversity comes from until OSIRIS-REx brings its sample back to Earth in 2023, Dworkin says.
The spacecraft took these images on January 17 when it was only a mile(1.6 kilometers) above Bennu's surface, using its NavCam 1 navigation camera, according to a NASA release.
The animated feature“Bennu's Journey” shows what's known and what remains mysterious about the life of asteroid Bennu and the origin of the solar system.
While the majority of asteroids are found within the asteroid belt between Mars and Jupiter, Bennu's orbit actually crosses over Earth's, making it much easier to get to.
If you were standing inside the boundaries of Bennu's Roche lobe and slipped on a banana peel, for example, not much would happen-- you would be captured by the lobe and fall back to the surface.
Over the next five years, OSIRIS-REx will map the asteroid's surface,measure its gravity and pick up a sample of Bennu's surface dust and send it back to Earth.
There's another possible explanation for Bennu's dust sprays, says OSIRIS-REx principal investigator Dante Lauretta of the University of Arizona in Tucson.
But scientists working on NASA's OSIRIS-REx mission to the space rock have used data gathered before the probe's arrival to calculate that Bennu's rotation rate is speeding up over time- by about 1 second each century.
The ejections have been observed around the time of Bennu's closest passage to the sun during the asteroid's elliptical orbit, which occurred this year on Jan. 10.
It is critical to know the orbit of Bennu because recent calculations produced a cumulative probability of 1 in 1410(or 0.071%) of impact with Earth in the period 2169 to 2199.[34] One of the mission objectives is to refine understanding of non-gravitational effects(such as the Yarkovsky effect) on this orbit, and the implications of those effects for Bennu's collision probability.
The spacecraft took these pictures on January 17,when it was only six kilometers above Bennu's surface and its NavCam 1 navigation camera was used according to a NASA publication.
After arriving at Bennu's space rock in early December, the 2018 spacecraft closed the orbit around the object, making Bennu the smallest body ever to orbit a man-made spacecraft.
So, it came as a big surprise when OSIRIS-REx photos showed particles streaming from Bennu's rugged surface on Jan. 6, just a week after the probe's arrival in orbit around the space rock.
Based on the group's calculations, the region around Bennu's equator is trapped within a gravitational feature called a rotational Roche lobe-- something that scientists had not yet clearly observed on an asteroid.
If the diversity is really there,it may mean that Bennu's surface has some pristine areas that are remnants of the original, larger rock it originally chipped off from, as well as some relatively fresh spots that have undergone recent activity.
OSIRIS-REx will pass later this month just 1.9 km from Bennu, entering the asteroid's gravitational pull and analysing its terrain.

This"super-resolution” view of asteroid Bennu was created using eight images obtained by NASA's OSIRIS-REx spacecraft on Oct.
