NASA’s OSIRIS-REx Probe Just Hit Another Milestone

NASA’s first asteroid sampling mission is closing in on its target. With just 11 days left until the big rendezvous, the OSIRIS-REx spacecraft is inching its way toward asteroid Bennu and has just 20 million miles to go before reaching the space rock. Launched on September 8, 2016, the OSIRIS-REx probe has been chasing the 1,640-foot-wide asteroid through space and is about to catch up with Bennu in its orbit around the sun.
