I'm really not trying to continue the "1st Question" arguments, but there is one point I really feel ought to be addressed, because it leads to some material I feel would be of interest to the board members - and even IDW, who may yet be lurking after insisting, literally, on being banned.
JayUtah: Have you ever read a book on the thermal design of spacecraft? Yes or no.
IDW: No, I haven't , and they're not easy to come by! Perhaps you can suggest a few titles.
and
IDW: As far as I know there simply arent any books published on the subject of spacecraft thermodynamics.
It took me about ten seconds of typing "thermal design of spacecraft" into the search bar for Amazon.com and waiting for about two dozen listings to be displayed, some for as little as US$28. Not all of them were available, but there are plenty more to be found with a little digging. Or one could go to a technical bookstore or a library. Or if one were to Google "thermal design of spacecraft" he would find many, many more reports and books which are available to purchase.
On the general topic of heat transfer, there is an excellent free textbook available in PDF:
A Heat Transfer Textbook, by John H. Lienhard IV and his son JHL V. The former gentleman is a professor at the University of Houston, who I have had the pleasure of meeting; his son is a prof at MIT. It's a very good introduction into all aspects of heat transfer.
Space Mission Analysis and Design, 3rd edition (affectionately known in the space business as "SMAD") contains a very good, succinct chapter on thermal design and control for spacecraft.
Here is a sampling of other references pertaining to spacecraft thermal design and control, from a few seconds of Googling:
Spacecraft Thermal Control
SPACECRAFT THERMAL CONTROL COATINGS DESIGN AND APPLICATION
Solar Absorptance and Thermal Emittance of Some Common Spacecraft Thermal Control Coatings, NASA-RP-1121
Thermophysical Data and Environments
Thermal Design Part of a Master's thesis for a small spacecraft design study.
Thermal design and test verification of GALAXY evolution explorer (GALEX)
Spacecraft thermal design for the IUE Includes, for example, discussion of thermal control technologies such as coatings, multi-layer insulation, louvers, and the simple expedient of deploying something before it cooled too much.
Perhaps this post isn't really on-topic for this subforum, but I thought it appropriate given the recent interest in the topic.
