NASA’s Artemis II crew in their Orion spacecraft is back on Earth. They successfully completed a parachute-assisted splashdown in the Pacific Ocean off the coast of San Diego at 8:07 p.m. EDT (5:07 p.m. PDT).

The Artemis II Crew - NASA astronauts Reid Wiseman, Victor Glover, Christina Koch and CSA (Canadian Space Agency) astronaut Jeremy Hansen are preparing for re-entry aboard the Orion spacecraft.

Orion’s crew and service module have separated. The crew module continues on its path towards Earth while the service module will harmlessly burn up in Earth’s atmosphere over the Pacific Ocean. The Artemis II return trajectory is designed to ensure any remaining debris does not pose a hazard to land, people, or shipping lanes.
