NASA s OSIRIS-REx mission is on the brink of discovering the extent of the mess it made on asteroid Bennu s surface during last fall s sample collection event. On Apr. 7, the OSIRIS-REx spacecraft will get one last close encounter with Bennu as it performs a final flyover to capture images of the asteroid s surface. While performing the flyover, the spacecraft will observe Bennu from a distance of about 2.3 miles (3.7 km) - the closest it s been since the Touch-and-Go Sample Collection event on Oct. 20, 2020. ....

OSIRIS-REx to Fly a Farewell Tour of Bennu


NASA/Goddard/University of Arizona
On April 7, NASA s University of Arizona-led OSIRIS-REx mission will give asteroid Bennu one last glance before saying farewell. Before departing for Earth on May 10, the OSIRIS-REx spacecraft will perform a final flyby of Bennu – capturing its last images of sample collection site Nightingale to look for transformations on Bennu s surface after the Oct. 20, 2020, sample collection event.
We are really excited that we get to take one last look at Bennu and are really curious about any way the surface might have changed as a result of TAG (the Touch-and-Go sample collection event),  said 
Dani DellaGiustina, lead scientist on the mission s image processing team and senior staff scientist at the UArizona  ....

On May 10, NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer, or the OSIRIS-REx spacecraft, will say farewell to asteroid Bennu and begin its journey back to Earth.
During its Oct. 20, 2020, sample collection event, the spacecraft collected a substantial amount of material from Bennu’s surface, likely exceeding the mission’s requirement of 2 ounces (60 grams). The spacecraft is scheduled to deliver the sample to Earth on Sep. 24, 2023.
“Leaving Bennu’s vicinity in May puts us in the ‘sweet spot,’ when the departure maneuver will consume the least amount of the spacecraft’s onboard fuel,” said Michael Moreau, OSIRIS-REx deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Nevertheless, with over 593 miles per ....
