I was really surprised that shape had such a huge influence on temp. If the craft was like a wafer with the plane pointing toward the Sun, they would have indeed have gotten cold. I doubt NASA thought too deeply about these considerations seeing as they were faking the landing for Cold War propaganda purposes.<br />Have you seen this video of a bogus model bobbling on the end of a string that's supposed to be a real space ship taking off from the Moon?<br /><br /><br />http://www.youtube.com/watch?v=9HQfauGJaTs<br />Carbon Conhttps://www.blogger.com/profile/11326150646151735913noreply@blogger.comtag:blogger.com,1999:blog-29179089.post-65226461104127383642014-01-01T13:24:09.081+10:002014-01-01T13:24:09.081+10:00Apollo 13 was (slowly but surely) becoming uncomfo...Apollo 13 was (slowly but surely) becoming uncomfortably cold, indicating that it was losing more heat than it was gaining (from exposure to the sun). Is that really so unbelievable? Granted, objects in space will get very hot on the side exposed to the sun, but the other half will get very cold. It seems to me that the equilibrium temperature inside the module will largely depend on the design of the spacecraft, and that it would make sense for engineers to bias it towards cooler to compensate for all the internal heat normally generated by the equipment. As for the spacesuits, apart from the fact that they are completely different from the spacecraft in almost every way, I would just note that they also get energy radiated by the moon, so the total heat they are exposed to may be significantly larger.Dan Huenoreply@blogger.com
