The OSIRIS-REx spacecraft, enclosed in a payload fairing, is towed past the Vehicle Assembly Building at NASA's Kennedy Space Center on its way to Space Launch Complex 41 at the adjacent Cape Canaveral Air Force Station. The United Launch Alliance Atlas V rocket that is to lift OSIRIS-REx into space was stacked at SLC-41 so the spacecraft and fairing could be hoisted and bolted to the rocket promptly. The spacecraft will be sent to rendezvous with, survey and take a sample from an asteroid called Bennu.
