Holy cow! I just visited arethuza's Wikipedia link below... I read the NASA trivia about the movie on a forum a few years back and it just popped into my memory. I had no idea these were incredibly rare. Yes, the irony him shooting 2001 wasn't lost on me. Without reflections, space is pretty dark (excluding starlight) so I imagine the new Canon lense will see a lot of space use. Provided it can be made sufficienty RAD-hard.

  Distant from stars like our sun, the temperature of space is just 2.73 Kelvins. It's pretty easy to work out the temperature for any given location in space -- just add up the effect of any nearby stars, whose radiation decreases as the square of distance, and add the background temperature of space itself, caused by the Big Bang afterglow. What this means is that, unless you're close to a star, it is very, very cold. Even at Pluto's relatively nearby location, the average temperature is only 33 Kelvins. http://en.wikipedia.org/wiki/Cosmic_microwave_background_radiation http://en.wikipedia.org/wiki/Cosmic_microwave_background_rad...
