Alot more things were cancelled before the ALT test.
Why are they called "International Standard" Payload Racks if they can only fit on Shuttle MPLMs, HTVs, and Dragons?
I am coding a spaceprobe with RTG's, and was wondering: how much mass does a spaceprobe with radio-thermal generators (the Voyager's, for exapmple) radiate away in its entire lifetime?

Assuming the Pu-238 turns to U-234 and the only mass lost is the difference in atomic mass (one alpha particle per atom), Voyager would lose 75 grams of mass eventually. But with a half-life of 87.7 years let's say it has lost 19 grams so far.
But I'm probably misunderstanding radioactivity.
(I didn't even take into account that it's not pure plutonium)
The alpha particles don't leave the generator anyway.
Where is the Elevator on the Soyuz launchpads located?seems I can never seem to find a picture of this on the internet,Just curious.Thanks
Amongst the best suspects I can find FAO, the Flight Activities Officer, but I'm not sure. Maybe EECOM or PROCEDURES ? I can't find anything on that, so if someone knows, thank you very much.
