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 over a year surveying the asteroid with five scientific instruments with the goal of selecting a location that is safe and scientifically interesting to collect the sample. OSIRIS-REx will return the sample to Earth in September 2023.

These images show Bennu 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.
