Every Risk NASA astronauts Facing with Artemis II, Worse than ever!
“I have to say from the data I've seen with regard to this heat shield, if I had to rate it ABCD, I'd rate it an F. You'd rate it an F. It's an F. It's a clear F. Clear.”
That blunt assessment comes from a veteran engineer with over 30 years of experience at NASA. In his assessment, Artemis 2 is shaping up to be an extremely high-risk mission, largely because Orion’s heat shield is performing far worse than expected.
But here’s the thing: the heat shield is only one of many serious challenges that could threaten or even derail this mission.
So what exactly are the risks facing the four astronauts heading toward the Moon on Artemis 2? And how does NASA plan to deal with these problems?
Let’s break it all down in today’s episode of Alpha Tech.
NASA is now facing one of the most critical moments of the Artemis program: Artemis 2, the first crewed mission to fly around the Moon in more than half a century.
Under the current schedule, the SLS rocket and the Orion spacecraft are already stacked on Launch Pad 39B at Kennedy Space Center in Florida, with teams preparing for the wet dress rehearsal, the crucial full-scale fueling test.

But just as excitement began to build, a wave of controversy erupted, centered largely on Orion’s Avcoat heat shield, the protective layer responsible for surviving temperatures of several thousand degrees as the spacecraft slams back into Earth’s atmosphere at roughly 11 kilometers per second.
Two of the most prominent voices raising concerns are Charlie Camarda, a former Space Shuttle astronaut and heat-shield specialist, and Daniel Rasky, a retired NASA thermal systems engineer with more than 30 years of experience. Rasky is also the co-inventor of PICA — Phenolic Impregnated Carbon Ablator, an ultra-light, highly heat-resistant material that later became the foundation for SpaceX’s PICA-X heat shield on Crew Dragon.
Both men have publicly expressed serious concerns on television, arguing that Orion’s current heat shield, still based on Avcoat technology dating back to the Apollo era of the 1960s, carries unacceptably high risk.

Camarda went so far as to call flying Artemis 2 with an essentially unchanged design “crazy,” emphasizing that debris shedding during Artemis I suggests the system is already operating near a potential failure threshold. Rasky was even more blunt, rating the heat shield an outright “F”, the lowest possible grade and stating plainly that humans should not be flown on a system like this.
Both experts suggested that robotic missions would be the wiser choice, pointing out that the United States has already won the Moon race once and does not need to rush at the cost of unnecessary risk. They also invoked the Challenger and Columbia disasters as sobering reminders that avoidable risks can lead to tragedy.
NASA, however, has not ignored these criticisms.
