In their first comments to the media, the Artemis II astronauts speak about the wonder and fear of the historic mission.
It has been almost a week since the four Artemis II astronauts completed their historic voyage around the Moon, and the crew said they have yet to come back to Earth mentally in their first press conference since their return.

The three Americans and one Canadian said their lunar flyby puts NASA in a much better position for a Moon landing by a crew in two years and an eventual Moon base. They spoke from NASA’s Johnson Space Center in Houston, their home base.
"This mission taught me that the unknown is way scarier than the known," said astronaut Christina Koch. "Every single time we accomplished a mission test objective, we all looked at each other and we're like, 'that actually went pretty well'.
Commander Reid Wiseman later told The Associated Press that he’s been so busy since getting back that he hasn’t had time to gaze up at the Moon, let alone Carroll Crater, the name suggested by the crew for a bright lunar crater in honour of his late wife.
“Being 252,000 miles away from home was the most majestic, gorgeous thing that human eyes will ever witness,” he said in an interview with the AP.
But hurtling back through the atmosphere at 39 times the speed of sound, “that is scary and that is risky.” That’s why he yearned for home midway through his flight. “You just want to hold your kids and you just want them to know that you’re safe.”
Wiseman, pilot Victor Glover, Koch and Canada’s Jeremy Hansen launched to the Moon from Florida on April 1, NASA’s first lunar crew in more than 50 years and by far the most diverse.
They became the most distant travellers ever — breaking Apollo 13's record — as they whipped around the lunar far side, illuminated enough to reveal features never viewed before by the human eye. The sight of a total lunar eclipse added to the wonderment.
Their Orion capsule, which they named Integrity, parachuted into the Pacific last Friday to close out the nearly 10-day voyage. Artemis II's Houston homecoming the next day coincided with the 56th anniversary of the launch of Apollo 13.
Wiseman said he and Glover “maybe saw two moments of a touch of char loss” to the heat shield as Integrity plunged through the fastest, hottest part of reentry. Once aboard the recovery ship, they peered at the bottom of the capsule as best they could, leaning over to view any signs of damage. They spotted a little loss of charred material on the shoulder, where the heat shield meets the capsule.
“For four humans just looking at the heat shield, it looked wonderful to us. It looked great, and that ride in was really amazing,” Wiseman said.
He cautioned that detailed analyses still need to be conducted. “We are going to fine-tooth comb every single, not even every molecule, probably every atom on this heat shield," he said.
The heat shield on the first Artemis test flight in 2022 — with no one aboard — came back so pockmarked and gouged that it pushed Artemis II back by months if not years. Instead of redoing it, NASA opted to change the capsule's entry path to minimise heating. Future capsules will sport a new design.
As the parachutes released right before splashdown, Glover said he felt like he was in freefall — like diving backwards off a skyscraper. “That’s what it felt like for five seconds,” he said, adding when the ride smoothed out: “It was glorious.”
Since their return, the four astronauts have endured round after round of medical testing to check their balance, vision, muscle strength and coordination, and overall health.
They even put on spacewalking suits for exercises under conditions simulating the moon’s one-sixth gravity of Earth to see how much endurance and dexterity future moonwalkers might have upon lunar touchdown.
NASA is already working on Artemis III, the next step in its grand moon base-building plans. The platform from which the rocket launches headed back Thursday to Kennedy Space Center’s Vehicle Assembly Building, where it will be prepped for next year’s Artemis launch.
Still awaiting an assigned crew, Artemis III will remain in orbit around Earth as astronauts practice docking their Orion capsule with one or two lunar landers in development by Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin.
Artemis IV will follow in 2028 under NASA’s latest schedule, with two astronauts landing near the Moon’s south pole.
NASA is aiming for a sustainable Moon presence this time around. During the Apollo moonshots, astronauts kept their visits short. Twelve astronauts explored the lunar surface, beginning with Apollo 11’s Neil Armstrong and Buzz Aldrin in 1969 and ending with Apollo 17’s Gene Cernan and Harrison Schmitt in 1972.
Koch said that since returning, she and her crewmates are “feeling even more excited and just ready to take that on as an agency.”
Everyone will need to accept extra risk to achieve all this and trust that any future problems can be figured out in real time, Hansen noted.
“We’re not going to be able to pound everything flat before we go. We're going to have to trust each other," he said.
While everything went smoothly for them, “it was also very clear to us that it can get pretty bumpy,” he said. Future crews will have to "understand it can get real bumpy real fast.”
