Article-I.D.: pur-phy.567 Posted: Fri Nov 12 01:03:23 1982 Received: Mon Nov 15 04:48:16 1982 The shuttle RADIATES heat into space. Stop and think, the sun does not need air between here and there to warm the earth. All bodies with a temperature above absolute zero radiate a "black body" spectrum. I suggest you get a basic physics text such as Halliday & Resnick and look up black body radiation.
