Space Image of the Day Gallery (September 2017)

Thursday, September 28, 2017: En route to visit an asteroid, NASA’s OSIRIS-REx spacecraft flew by Earth on Friday (Sept. 22) and captured this stunning photo of our “blue marble.” The spacecraft passed 10,711 miles (17,237 kilometers) over Antarctica during the gravity-assist flyby, which gave the spacecraft a speed boost on its way to asteroid Bennu. — Hanneke Weitering
