Howcome nobody thought of using the original design, that
didn't fall apart?
You mean the foam made using CFCs? Can't do that. Ozone hole, ya'
know!
NASA has an exemption.
I don't know if they have an exemption or not, but tile failure was
not a major problem until environmentalists forced the discontinuation
of fluorocarbon(freon)-based foaming agents. NASA used hydrazine
instead, and the tile failures began.
Interesting.
The first thing I remember seeing published by NASA (in the no-longer-mailed
(at lesat to me)) NASA Tech Briefs was a lot of stuff about tile repair and
replacement.
And I didn't know the tiles were foamed, anyway. I thought they were
pressed and sintered slabs of silica fibers.
No. The _foam_break-away_ failures began after the switch away from
CFC's.
