There’s a few kits I’d like to see made on this topic. They are:
Voyager, Viking, and other space probes
Skylab
What about you?
I thought Skylab had been done once. Maybe I’m just remembering a scratchbuild I saw sometime way back.
Check out http://www.realspacemodels.com/ . They have most of the probes you were asking about.
Skylab was done by Vista Replicas, whom developed a nasty habit of taking peoples money and disappearing.
Glenn at Realspace is working on a Skylab but the truss needed to support the Apollo Telescope Mount poses a huge technical challenge.
