OSIRIS-REx Earth Gravity Assist

OSIRIS-REx is NASA's mission to explore near-earth asteroid Bennu, collect a sample, and return it to Earth. To get to Bennu, however, OSIRIS-REx must first leave the plane of Earth's orbit and match the orbital tilt of its target. On September 22, 2017, OSIRIS-REx will approach Earth and fly over its southern hemisphere, passing within 11,000 miles of Antarctica. This gravitational slingshot will bend its trajectory by six degrees, sending the spacecraft on a path to intercept Bennu. Shortly after the flyby, OSIRIS-REx will look back at Earth and take images and spectra, ensuring that its instruments are ready for arrival at Bennu in 2018.
