NASA Astronaut Calls Artemis II Reentry Strategy ‘Irresponsible’ Ahaed of Splashdown

The Artemis II crew had already done the hard work… or so it seemed. They survived liftoff, passed through radiation fields, broke the all-time record for how far humans have traveled from Earth, and watched a solar eclipse from behind the Moon. They’re almost home now.

And a former NASA astronaut says returning home could be a big chance The most dangerous part of them all.

The Artemis II spacecraft is scheduled to land off the coast of San Diego on Friday at approximately 8:07 PM ET. But before that, the crew—commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen—must survive reentry: the phase of flight in which the capsules plunge back into Earth’s atmosphere at more than 25,000 miles per hour, heating the outside of the spacecraft to more than 5,000 degrees Fahrenheit.

Standing between the crew and this heat is a shield that was badly damaged in the last mission.

What Happened to the Artemis II Heat Shield?

When the uncrewed Artemis I capsule returned from its test flight around the Moon in 2022, mission teams found: heat shield It had returned with associated blisters and cracks. An investigation determined that the gases produced inside the outer material of the shield were not able to escape properly during reentry, causing pressure to build, cracks to form, and the charred material to break in many places.

Here’s the problem: By the time the findings were complete, the heat shield had already been installed on the Artemis II capsule, and it was too late to replace it. NASA’s solution was not to replace the shield, but to change the spacecraft’s reentry orbit using what is called a “penthouse” approach rather than the “jump” reentry used on Artemis I, in the hopes of creating more favorable heating conditions and limiting further cracking.

Why Is Re-Entry the Most Dangerous Part?

Former NASA astronaut Charlie Camarda, a heat shield expert who flew on the first Space Shuttle mission after the 2003 Columbia disaster, doesn’t believe this fix is ​​enough. He was invited to a NASA headquarters meeting in January to review the agency’s research data and left unconvinced.

Camarda claims that the tools NASA used to analyze the problem were inadequate, comparing them to tools that failed to capture the problems behind both the Challenger and Columbia disasters. He believes that the root cause of the Artemis I heat shield damage was an inherent structural failure, not just a matter of re-entry angle, and that NASA’s modified orbiter did not solve the underlying problem.

“It is irresponsible for us to decide to fly the crew in a vehicle with a known defective heat shield,” Camarda said. “We’re trying to prevent the loss of the Artemis II crew. History doesn’t repeat itself because engineers forgot the equations. It repeats itself because organizations forgot how to listen.”

Camarda emphasized that he did not foresee a catastrophic failure. He thinks the mission will probably return home safely. His deeper fear is that a safe landing will be seen as confirmation that NASA’s decision-making is sound, setting the stage for more serious failure down the line.

NASA Officials Discuss

NASA officials have repeatedly argued that safety is a top priority and that the agency fully understands the heat shield’s limitations. Former NASA Associate Administrator James Free said engineers determined that the crew’s safety parameters under modified orbit were “good.”

“How you get into the atmosphere is important,” Free said. “If you limit the angle it comes from, that limits how far downrange you can go, which limits your landing attempts, but you still stay within the temperature limits that you need for Artemis II, and that’s what they’re planning.”

Pilot Victor Glover acknowledged the gravity of the moment while in the spacecraft this week.

“I’ll be honest, and I’ve actually been thinking about joining since April 3, 2023, when we were appointed to this position,” Glover said. “We need to go back. There’s a lot of data you see already, but all the good things are coming back with us.”

Splashdown is scheduled for Friday off the coast of San Diego around 8:07 PM ET. A diver will photograph the heat shield from below as it recovers, providing the first evidence of how it is performing.
