How does it hold up in vacuum when heated to 250F and then quickly cooled to -250F? It doesn’t.

Well genius, check the temperature specs of Locktight in a vacuum. It doesn’t work.

Heat a nut/bolt to +250F and the rapidly cool to -250F in a vacuum. Repeat a few million times. Any notable affect?

How to those adhesives work in a vacuum when temperatures range quickly from -250F to +250F? They don’t. You need to attend a class in aerospace materials.

You left out the OTHER END: Optimum temperature range is range -65ºF to 650ºF. Space vehicles must handle down to -250F in a vacuum with the temperatures rapidly changing from the high end to the low end. Most plastics, of which LockTite is a member, out gas in a vacuum until they are all gone.

Loctite on a heat shield? Seriously?

The important issue is whether the muslins feel good about this project.

Where are they getting their fasteners? Harbor Freight?

My, my, my - aren’t we sensitive. Do you work on the project?
Come on, I wasn’t being serious. If it was really as simple as putting on some Loctite (or some other easily available and cheap adhesive), doubtless that would have been done. This is known in English as a “joke,” which is usually appreciated by people who have something known as a “sense of humor.”

Too many people throw barbs at what I regard as one of the very few government agencies that provides a positive influence on our society. Then there are the "Apollo Deniers", who irritate me to my core. Pardon me if I am defensive of that bunch.
