For those who are curious about the answers, but don't care about the 90% filler that this article is made of: - they had documentation on the apollo shields, but few people who'd actually worked on it - NASA redeveloped Avcoat, a combination of fiberglass and high-tech plastics, that was used, in an earlier form, for Apollo’s heat shield - if it worked as intended, about 20 percent of the shield burned up on the way down In addition to being almost entirely filler and answering the titular question for no good reason whatsoever only in the last 25% of the article; none of the numbers are in SI. I really hate modern journalism.

In the following film, you can watch them make and test the Apollo ablative heat shields and capsule blankets. Apollo Spacecraft Status Report #2 - 1966 NASA Educational Documentary - WDTVLIVE42 https://www.youtube.com/watch?v=mk5QI0-k6nc https://www.youtube.com/watch?v=mk5QI0-k6nc > I really hate modern journalism. In my opinion, the journalism of the 60's wasn't any better. Technical matters have always been simplified to a degree that scientifically educated people find distressing. At least today, the internet gives the interested person access to source documents nearly as easily as depicted in "Star Trek".
