Whole and undivided

Ultimately, Integrity was inspired by something one of their instructors said while on a team-building trip to Iceland.

“He coined this for us, and we held on to it,” said Hansen, who, unlike his NASA crewmates, is a Canadian Space Agency astronaut. “It was this idea that you’re not a person who has integrity, you’re a person who strives to be in integrity. Sometimes you’re out of integrity, and sometimes you’re in your integrity. That was profound for all of us.”

For Glover, it boiled down to the definition.

“The Latin root means ‘whole.’ It’s a very simple concept, and it’s about being whole. This crew comes together as pieces—the four of us and our backups—but the six of us make up a whole team. The vehicle, the pieces come together and make up a whole spacecraft,” he said.

“What people anecdotally say is that integrity is what you do when no one’s watching. That, and truth, honor, and integrity matter,” said Glover. “There are so many layers to that name and what it means and what it inspires.”

Integrating Integrity

Integrity is one of the tenets of the Astronaut Code of Professional Responsibility. It is also one of the Canadian Space Agency’s core values.

“We all strive to be in integrity all of the time, but integrity isn’t an absolute that you either have or don’t have,” said Koch. “So this helps us give grace and build trust with each other.”

“I hope that people hearing [the name] over the 10 days of the mission appreciate all of the different things that it means, from a whole ship, a whole crew, to a wholeness and wellness that I think humanity just needs. We need to hear more of that togetherness and wholeness,” said Glover.

Now that it has been announced, next up is for Integrity to be used as the crew’s possible call sign.

“We waited to make sure the whole enterprise was ready for us to announce it before we even used it,” said Glover. “I think we’ll start using it in sims: ‘Houston, Integrity. Integrity, Houston.’ That’s the plan.

“But if someone doesn’t like that, then we won’t, and we can say Orion,” he said.

NASA confirms “independent review” of Orion heat shield issue

NASA has asked a panel of outside experts to review the agency’s investigation into the unexpected loss of material from the heat shield of the Orion spacecraft on a test flight in 2022.

Chunks of charred material cracked and chipped away from Orion’s heat shield during reentry at the end of the 25-day unpiloted Artemis I mission in December 2022. Engineers inspecting the capsule after the flight found more than 100 locations where the stresses of reentry stripped away pieces of the heat shield as temperatures built up to 5,000° Fahrenheit.

This was the most significant discovery on the Artemis I, an unpiloted test flight that took the Orion capsule around the Moon for the first time. The next mission in NASA’s Artemis program, Artemis II, is scheduled for launch late next year on a test flight to send four astronauts around the far side of the Moon.

Another set of eyes

The heat shield, made of a material called Avcoat, is attached to the base of the Orion spacecraft in 186 blocks. Avcoat is designed to ablate, or erode, in a controlled manner during reentry. Instead, fragments fell off the heat shield that left cavities resembling potholes.

Investigators are still looking for the root cause of the heat shield problem. Since the Artemis I mission, engineers conducted sub-scale tests of the Orion heat shield in wind tunnels and high-temperature arcjet facilities. NASA has recreated the phenomenon observed on Artemis I in these ground tests, according to Rachel Kraft, an agency spokesperson.

“The team is currently synthesizing results from a variety of tests and analyses that inform the leading theory for what caused the issues,” said Rachel Kraft, a NASA spokesperson.

Last week, nearly a year and a half after the Artemis I flight, the public got its first look at the condition of the Orion heat shield with post-flight photos released in a report from NASA’s inspector general. Cameras aboard the Orion capsule also recorded pieces of the heat shield breaking off the spacecraft during reentry.

NASA’s inspector general said the char loss issue “creates a risk that the heat shield may not sufficiently protect the capsule’s systems and crew from the extreme heat of reentry on future missions.”

“Those pictures, we’ve seen them since they were taken, but more importantly… we saw it,” said Victor Glover, pilot of the Artemis II mission, in a recent interview with Ars. “More than any picture or report, I’ve seen that heat shield, and that really set the bit for how interested I was in the details.”
