I suspect that a good IT cut would probably do better than an SC in either
application. In the deep space situation, a copper slug in a dewar sounds like
a reasonable addition to the design.
If you're going to do dewars, then you're talking USOs for which the
technology is quite well developed with ovens, etc.
But that's a kilo, several watts, and a liter.
What you want is something that is better than, say, 0.1 ppm, that is
comparable in mass/power/volume/cost to an existing 1-5 ppm TCXO (about
1x2x0.5 cm)
