Comment on GAO Discusses Orion Heat Shield Anomaly Root Cause, Artemis 3 Internal Schedule by Rod Price

In reply to Alex Longo.

Thanks Alex. Interesting/surprising that when NASA decided to switch to blocks (to save time or cost) they didn’t switch to a material (PICA) that was known to work as blocks. Since/if this is the only flight test of Avcoat blocks, and it failed, it’s hard to see how they can come up with a flight rational to fly crew in the next Orion with the same heatshield design as this one that spalled so badly.
