Will this be Elon to the rescue? Maybe - if it is, we should be getting used to it. Elon Musk is a national treasure and should be used as such. He can see what others don't see. And he can innovate where others dare not tread. Now that the cat is really out of the bag about the heat shield on Artemis, it will be all eyes on NASA. Time to fix this issue NASA - we don't need another national tragedy.
Last week, the long (and I mean long) awaited re-entry of Artemis II safely splashed down off the coast of San Diego. Okay - I used the word "safely". Maybe not the correct word to use. Wait - this is NASA. The most cautious and careful organization in the world. That is, up until the Artemis II flight. Few know this right now, but it will become more well known in the near future. The decision was made to launch Artemis II, even though it had a sketchy heat shield. But why then, take the chance? China. We have to beat China to the Moon. Even though we already landed there fifty years ago.
When the uncrewed Artemis I came back to Earth in late 2022, we saw there was a huge problem. The heat shield had deep cracks and some chunks missing. It was by a wing and a prayer that Artemis I did not burn up on re-entry. The brainy ones at NASA set out to fix this near catastrophic event by doing some fixes on the heat shield before Artemis II launched. One minor problem - the fixes did not work well. For the second time in the Artemis program, we sent a mission towards Mars by a wing and a prayer. Only this time, it had four humans on board.
Why is this different from the re-entries we have had since Mercury, Gemini, Apollo, and numerous space shuttle missions? They all had heat shields. Did we lose the recipe? Is it that Artemis is coming in so much faster (Mach 30+)? Whatever the reason, we better button this thing up before Artemis III. The fact we got Artemis II back safely, might have been more providence than luck or good planning.
Elon Musk and his SpaceX team have also been working on the heat shield issue. Elon might have a better solution than the lemon we have used in the first two Artemis flights. Instead of using some super ablative, Musk is experimenting with using a specially manufactured metal heat shield. Will it be better than what Artemis is currently using? It sure can't be much worse.
As a citizen, as a fan of space exploration, I want NASA to succeed. This heat shield issue should be the last of our worries instead of the first of our concerns. Putting the heat shield aside, I was hoping that NASA could be focusing on better shielding of the capsule was when it leaves low Earth orbit, it is bombarded with harsh solar radiation. That problem needs to be fixed long before we attempt a flight to Mars or lengthy visits to the Moon's surface.
