After traveling through space for more than two years and over two billion kilometers, NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft arrived at its destination, asteroid Bennu, on Monday, Dec. 3, 2018. The spacecraft will spend almost a year surveying the asteroid with five scientific instruments with the goal of selecting a location that is safe and scientifically interesting to collect a sample which OSIRIS-REx will return to Earth in September 2023.
Asteroid Rotation

This series of
images taken by the OSIRIS-REx spacecraft shows Bennu in one full rotation from
a distance of around 50 miles (80 km). The spacecraft’s PolyCam camera obtained
the thirty-six 2.2-millisecond frames over a period of four hours and 18
minutes. Credits: NASA's Goddard Space Flight Center/University of Arizona

Bennu Approach Fly In

This picture
shows the OSIRIS-REx spacecraft’s view of Bennu during the final phase of its
journey to the asteroid. From Aug. 17 through Nov. 27 the spacecraft’s PolyCam
camera imaged Bennu almost daily as the spacecraft traveled 1.4 million miles
(2.2 million km) toward the asteroid. The final images were obtained from a
distance of around 40 miles (65 km). During this period, OSIRIS-REx completed
four maneuvers slowing the spacecraft’s velocity from approximately 1,100 mph
(491 m/sec) to 0.10 mph (0.04 m/sec) relative to Bennu, which resulted in the
slower approach speed at the end of the video. Credits: NASA's Goddard Space
