Hey Guys I'm new to this discussion board. for the past couple of months, I have been looking over these silly Flat earth claims, [like] "the melting points of the metals used in satellites are far lower than the temperature in the "thermosphere" where satellites supposedly are." - Eric Dubay I have been trying to check this whole thermosphere thing. I hear some say that things don't get very hot when in the thermosphere because there are very little gas particles to allow for convection and conduction but their is still radiation, which is able to heats things up in a vacuum. Is Dubay inaccurate when he claims that the thermosphere should be able to melt the satellites? And how can our satellites and other space craft survive the thermosphere?
