There were notable white streaks across the #HeatShield. All of these appeared to originate at boundaries between tiles, suggesting hot gas may have penetrated these boundaries. There were also indications of cracked tiles and broken edges. The problem is that, with the signs of damage, such a heat shield would appear to require a fair amount of inspection and #refurbishment before another launch.

Whether or not the #HeatShield worked, there was nothing I could do. There’s so much we didn’t model correctly on entry. There was a point—there’s something that I feel that I am not ready to say to the public yet

Artemis II Crew Returns After Lunar Flyby; Questions Linger on Heat Shield Durability

Artemis II astronauts splashed down safely after a 10-day moon trip. NASA is looking into heat shield durability after a prior test issue.

#ArtemisII, #MoonMission, #SpaceExploration, #NASA, #HeatShield

https://newsletter.tf/artemis-ii-crew-returns-after-moon-trip-heat-shield-issue/

The Artemis II mission covered 694,481 miles around the moon. This is the first crewed moon trip in over 50 years.

It will take several hours to several days for engineers to complete their initial inspections of the #Orion spacecraft, but the successful return to Earth on Friday proved the #HeatShield did its job.

#Spacecraft are designed to be as un-aerodynamic as possible to maximise drag and help them slow down.

This deceleration during #reentry can be extremely harsh. A shock wave will envelop the spacecraft, creating air temperatures of 10,000°C 🌡️ or more – about twice the temperature of the surface of the #Sun.

The #Artemis I #HeatShield ablation during re-entry was much larger than expected. Large chunks of material separated from the heat shield in some places.

#Artemis II astronauts will splash down Friday using a new reentry technique at 32 times the speed of sound that has yet to be tested in real-world scenarios. Because Artemis I went back into space between the first dip into the atmosphere, the hot interior of the #HeatShield kept producing gases, but the exterior was no longer shedding material fast enough to allow those gases to escape. Pressure built up, which #cracked the heat shield https://www.latimes.com/science/story/2026-04-09/artemis-ii-to-put-new-reentry-plan-to-test

The #Artemis II #HeatShield 🛡️🔥 is even less permeable than the one flown on Artemis I.The more permeable parts of the Artemis I heat shield did not suffer the same char loss as the less permeable part. #NASA doesn’t have a complete physics picture of what happened on Artemis I, but they chose to change the re-entry trajectory to minimize the thermal strain on the shield https://www.nationalgeographic.com/science/article/artemis-ii-heat-shield-nasa

🚀🎉 NASA's latest brainwave: Let's send #astronauts around the #moon in a cobbled-together, blazing tin can! Perfectly safe—except for that pesky little problem where the heat shield disintegrates like soggy cereal. 🥣🌌 But hey, who needs comprehensive testing when you can just wing it on a multimillion-dollar joyride? 🤡🔥

#Starliner's #HeatShield is made of #Boeing Lightweight Ablator, a honeycomb-like structure that is hand-filled with the ablator. In areas that receive less heat, the capsule is covered with a mix of thermal blankets and heat shield tiles, both of which have #SpaceShuttle heritage.

The descent through the atmosphere will reach temperatures of 1,650 degrees 🔥 Celsius. Once through the thicker part of the #atmosphere, the heat shields are #jettisoned 🗑️ https://www.nasaspaceflight.com/2024/06/starliner-cft-launch/
