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.
A space shuttle main engine that helped bring that program to a close will help propel the next Artemis mission in 2028. NASA’s new rocket, called the “Space Launch System,” is designed, built, tested, and managed at the Marshall Space Flight Center in Huntsville. It uses technology from the retired space shuttle program. That includes main engines that were used earlier during blastoff of the reusable space plane.
One of the four shuttle engines used during the upcoming launch of Artemis-3 comes from STS-135. That was the final launch of the shuttle in 2011 with astronauts Chris Ferguson, Doug Hurley, Sandra Magnus, and Rex Walheim. That mission flew to the International Space Station to deliver one last load of supplies before the shuttle program was retired. NASA’s engine supplier Harris3 says three other engines from previous shuttle launches will also be used on the Artemis-3 blastoff. Those earlier missions serviced the Hubble Space Telescope and delivered a set of solar panels and part of the spine-like truss of the space station.
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.
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 San Diego coast, along with a squadron of military planes and helicopters.
The last time NASA and the Defense Department teamed up for a lunar crew's reentry was Apollo 17 in 1972. Artemis II was projected to come screaming back at 36,170 feet (11,025 meters) per second — or 24,661 mph (39,668 kph) — just shy of the record before slowing to a 19 mph (30 kph) splashdown.
“A perfect bull’s-eye splashdown,” reported Mission Control’s Rob Navias.
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 (406,771 kilometers). 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.
Their sense of wonder and love awed everyone, as did their breathtaking pictures of the moon and Earth. The Artemis II crew channeled Apollo 8's first lunar explorers with Earthset, showing our Blue Marble setting behind the gray moon. It was reminiscent of Apollo 8’s famous Earthrise shot from 1968.
“It just makes you want to continue to go back,” Radigan said on the eve of splashdown. “It's the first of many trips and we just need to continue on because there’s so much” more to learn about the moon.
Their moonshot drew global attention as well as star power, earning props from President Donald Trump; Canadian Prime Minister Mark Carney; Britain's King Charles III; Ryan Gosling, star of the latest space flick “Project Hail Mary”; Scarlett Johansson of the Marvel Cinematic Universe; and even Captain Kirk himself, William Shatner of TV’s original “Star Trek.”
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.
“We can’t explore deeper unless we are doing a few things that are inconvenient,” Koch said, “unless we’re making a few sacrifices, unless we’re taking a few risks, and those things are all worth it.”
Added Hansen: “You do a lot of testing on the ground, but your final test is when you get this hardware to space and it’s a doozy.”
Under the revamped Artemis program, next year’s Artemis III will see astronauts practice docking their capsule with a lunar lander or two in orbit around Earth. Artemis IV will attempt to land a crew of two near the moon’s south pole in 2028.
The Artemis II astronauts' allegiance was to those future crews, Wiseman said.
“But we really hoped in our soul is that we could for just for a moment have the world pause and remember that this is a beautiful planet and a very special place in our universe, and we should all cherish what we have been gifted,” he said.
