Foam

I’m as big of a supporter of the space program, so don’t take this wrong way. But does anyone else find it discomforting that so much is at stake because of FOAM insulation? I mean, I wonder if it’s the same stuff that those cheap coolers you buy at the grocery store are made out of? If it is – HOLY COW! If not, then I suggest NASA hire an engineer to come up with a better name for it so that the general public can stop calling it regular ol’ foam.
