I think they were, though, because NASA had to replace tiles.

I don't know how extensively the replacement was, but I know that they did replace tiles.

So I guess there was some wear and tear on them, but I don't know if it was ablative.

I do remember seeing or reading something where there was a person whose job it was to refashion those tiles for the space shuttle and literally had to handcraft them like to fit perfectly.

Yeah.

All right.

So here's the questions about the heat shield, the ablative material that need to be answered.

Did it behave exactly as predicted?

Did it erode more than expected?

How much margin was there, right?

Meaning how much of it was left at the end of that reentry?

Was there enough to make it safe?

Did the reentry profile perform as they hoped?

It seems like it did.

And did it reveal any concerning items for Artemis III, which is essentially a summary of everything I just listed.

But

Bottom line is we'll find out all that, but on first blush, it worked.

NASA also has a list of things that they, data they collected about the astronauts themselves, right?

So they wanted to, they tracked and wanted to get more information on astronauts' sleep, their stress, their cognition, their teamwork, their immune response, their general physiology, and the amount of radiation that they were exposed to and then what effect would or could that have on them.

So overall, double thumbs up.
