HOUSTON (AP) — Artemis II’s astronauts returned from the moon with a dramatic splashdown in the Pacific on Friday to close out humanity’s first lunar voyage in more than a half-century.

It was a triumphant homecoming for the crew of four whose record-breaking lunar flyby revealed not only swaths of the moon’s far side — never seen before by human eyes — but a total solar eclipse. They emerged from their bobbing capsule into the sunlight one by one.

Commander Reid Wiseman, pilot Victor Glover, Christina Koch and Canada’s Jeremy Hansen hit the atmosphere traveling Mach 33 — or 33 times the speed of sound — a blistering blur not seen since NASA’s Apollo moonshots of the 1960s and 1970s. Their Orion capsule, dubbed Integrity, made the plunge on automatic pilot.

The tension in Mission Control mounted as the capsule became engulfed in red-hot plasma during peak heating and entered a planned communication blackout.

Thousands of miles away, the astronauts’ families huddled in Mission Control’s viewing room, where cheers erupted when the capsule emerged from its communication blackout and again at splashdown.

“This is an incredible test of an incredible machine,” NASA Associate Administrator Amit Kshatriya said. “This has been a gift to the world from NASA.”

All eyes were on the capsule’s life-protecting heat shield that had to withstand thousands of degrees during reentry. On the spacecraft’s only other test flight — in 2022, with no one on board — the shield’s charred exterior came back looking as pockmarked as the moon.

Like so many others, lead flight director Jeff Radigan anticipated feeling some of that “irrational fear that is human nature,” especially during the six-minute blackout that preceded the opening of the parachutes. The recovery ship USS John P. Murtha awaited the crew’s arrival off the coast of San Diego, along with a squadron of military planes and helicopters.

Launched from Florida on April 1, the astronauts racked up one win after another as they deftly navigated NASA’s long-awaited lunar comeback, the first major step in establishing a sustainable moon base.

Artemis II didn’t land on the moon or even orbit it. But it broke Apollo 13’s distance record and marked the farthest that humans have ever journeyed from Earth when the crew reached 252,756 miles.

Then in the mission’s most heart-tugging scene, the teary astronauts asked permission to name a pair of craters after their moonship and Wiseman’s late wife, Carroll.

During Monday’s record-breaking flyby, they documented scenes of the moon’s far side never seen before by the human eye along with a total solar eclipse. The eclipse, in particular, “just blew all of us away,” Glover said.

Despite its rich scientific yield, the nearly 10-day flight was not without technical issues. Both the capsule’s drinking water and propellant systems were hit with valve problems. In perhaps the most high-profile predicament, the toilet kept malfunctioning, but the astronauts shrugged it all off.
