[APML] Film in Space (was The End of Tech Pan???)



Hi Sean,

I don't have plans to build a space telescope any time soon, but there's
no reason it wouldn't work with film.  For many years, spy satellites
used film cameras in space.  When a roll was finished, they'd deorbit a
"honey bucket" with the exposed film inside.  The real fun started when
these things occasionally came down far from where they were supposed to
- the race was on to try and grab the other side's film can, sometimes
snagging them out of the air as they descended on parachutes (which I
believe was a typical retrieval method on one's own territory as well).
I'll bet that a few lives were lost playing this game.

Sure, the resolution may be better with a CCD, especially a
taxpayer-funded CCD, and of course it's far simpler to transmit the
images via downlink than to deorbit film cans, but there's no technical
reason why a film camera won't work in space, as history shows.
