The Artemis II astronauts share a group hug aboard the Orion capsule. hide caption toggle caption NASA astronauts Reid Wiseman, Victor Glover and Christina Koch and Canadian Space Agency astronaut Jeremy Hansen were ensconced in the Orion space capsule when they dropped into the Pacific Ocean off the coast of San Diego at 8:07 p.m. Friday. The USS John P.
