Artemis II crew praises moonship performance, highlights heat shield success
The Artemis II astronauts who ignited a lunar renaissance gave high marks Thursday to their moonship, especially the heat shield, for its performance during reentry.
In their first news conference since returning to Earth, 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.
Commander Reid Wiseman, pilot Victor Glover, Christina Koch and Canada's Jeremy Hansen launched to the moon from Florida on April 1, NASA's first lunar crew in more than a half-century 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 re-entry. 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 backward 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 already is 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.
