Where is Elon Musk's Tesla Roadster with Starman?

Insulation again and I'm still willing to wager the LCD screen was a light panel (ie: type used external to ISS) with a clear gel over it. Yes I agree it could be done, my question is did they for a for a PR stunt since simple ballast would give the same results. I don't think so. But with Musk he might just have. Though it's a nice car, the bottom line has to be that has to be to date the WORST idea for a manned space vehicle on record. (Bet you they had solid tires or boom, boom, boom, boom).

Mayhap the good Doctor got the chameleon circuit fixed and was really in the space suit listening to jams on the radio? Now that I'll buy. Sounds like Moffit script to me. Wonder what else besides Bowie SHE was listening to? I'll save that speculation for the music forum.

That depends on what you mean by "close." Remember what you wrote - There's no means for conduction. It's close to absolute zero on some places on the Moon, for instance. If someplace is in the shade, then something else aside from direct sunlight has to be keeping it above absolute zero. Even on Mercury, some of the temps get within shouting range of "close to absolute zero." Well, at least "pretty darn cold." (-180 C vs -270 C)pjknibbs wrote:... Also, there's nowhere in the Solar System that gets close to absolute zero, because there's a rather large fusion reactor nearby sending heat in all directions!
Past reaching ab0 +/- once per equatorial orbit there's the inverse square law.
Still the void awaits and
there is naught of neither there.
Which translates into as far as thermal radiation is concerned much past the asteroid bet what the sun is putting out is mighty darn little. It applies to light as well but with a higher index than the light's ability to produce heat which is separate law. .Wikipedia wrote: The inverse-square law, in physics, is any physical law stating that a specified physical quantity or intensity is inversely proportional to the square of the distance from the source of that physical quantity. The fundamental cause for this can be understood as geometric dilution corresponding to point-source radiation into three-dimensional space.

That's not close to absolute zero in my book. Heck, nitrogen isn't even liquid in such balmy conditions! I think the coldest place we detected in the universe was a nebula which was expanding so fast into space that it had cooled to around 1K, but that was light-years away.Morkonan wrote:Even on Mercury, some of the temps get within shouting range of "close to absolute zero."

Even the cosmic background radiation left over from the explosion at the formation of the universe hasn't cooled to absolute zero yet.
If anything does it means the literal beginning of the end of the universe.
No motion, no work/energy, no more entropy, nothing.

Sorry. You're right. Here's what I'm thinking of when I read you're posts and trucked into my "Library" in a closet and dug around. "The Bible" 1971 edition "NASA STP" (Standard Test Protocols)
My apologies.
They were pretty insular back then and my calculator is on this thing I'm typing on. Temp (F)-32/1.8=(C). I'm sure that "engineering pad" changed later. They always used to test for and against worse case scenarios and the rule of thumb was "from 0 to fire".For purposes of engineering testing a standard temperature range of +450/-450 (F) is mandated.
My apologies.
