NASA's OSIRIS-REx spacecraft has arrived at the asteroid Bennu

NASA's OSIRIS-REx spacecraft has officially arrived at the asteroid Bennu after a more than two-year-long journey. The spacecraft rendezvoused with its target around noon EST, and NASA confirmed the arrival a few minutes thereafter during a live event today. Achievement unlocked: "We have arrived!" Our @OSIRISREx mission reached asteroid Bennu, where it will spend almost a year mapping and studying to find a safe location to collect a sample. OSIRIS-REx launched in 2016 and its mission is to collect a sample from Bennu and return it back to Earth for study.
