After traveling two billion miles over more than two years, NASA's OSIRIS-REx spacecraft has arrived at asteroid Bennu. The spacecraft will survey the asteroid, collect a sample, and bring it back home in 2023. From NASA's Goddard Space Flight Center/University of Arizona:
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.
Below is a set of images compiled during OSIRIS-REx's approach. Learn more at: ISIRIS-REx: Asteroid Sample Return Mission.
From NASA/Goddard/University of Arizona:
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.
