Charlie/All,

Definitely no RTGs.  The whole Observatory was powered by solar cells and
heat pumps.  As I understand it, only a few of the instruments used
"nanocurie and microcurie" amounts of radioisotopes for internal calibrations.

Sources couldn't be too large or they would interfere with the detection
systems of the Observatory.
