Splashdown of Artemis II astronauts concludes historic 10-day moon mission.

The Artemis II capsule and its four-member crew streaked through Earth’s atmosphere and safely splashed down in the Pacific Ocean after nearly ten days in space, capping the first voyage by humans to the vicinity of ⁠the moon in over half a century.

NASA’s gumdrop-shaped Orion capsule, dubbed Integrity, parachuted gently into the sea off the Southern California coast shortly after 5pm PT (1am Irish time), concluding a mission that took the astronauts deeper into space than anyone had flown before.

The Artemis II flight, traveling a total of 1,117,515 km across two Earth orbits and a climactic lunar flyby some 252,000 miles away, was the debut crewed test flight in a series of Artemis missions that aim to start landing astronauts on the lunar surface starting in 2028.The splashdown, about two hours before sunset, was carried by live video feed in a NASA webcast.

Recovery teams were standing by to secure the floating capsule and retrieve the crew – US astronauts Reid Wiseman, 50, Victor Glover, 49, and Christina Koch, 47, along with Canadian astronaut Jeremy Hansen, 50.

The crew’s homecoming cleared a critical final hurdle for the Lockheed Martin-built Orion spacecraft, proving it would withstand the extreme forces of re-entry from a lunar-return trajectory.

It followed a white-knuckle, 13-minute fiery plunge through Earth’s atmosphere, generating frictional heat that sent temperatures on the capsule’s exterior soaring ‌to some 2,760 degrees Celsius.

At the peak of re-entry stress, ⁠as expected, intense heat and air compression formed a red-hot sheath of ionized gas, or plasma, that engulfed the capsule, cutting off radio communications with the crew for several minutes.

The tension broke as contact was re-established and two sets of parachutes were seen billowing from the nose of the free-falling capsule, slowing its descent to about 15 mph (25kph) before Orion gently hit the water.
