Cool! You taught me something I should have known already:
Why does NASA use so much gold foil? - Geek.com
When you see a space contraption draped in gold foil, remember that the foil is probably a heat shield or, more practically, a radiation shield. The sun transmits heat on Earth mostly by warming the atmosphere, and we experience that heat by convection, like a turkey in the oven.
That is some excellent gold info!!!
