Comment on Apollo Moon Landing Hoax – Scientific Evidence by jfb.

m0 is propellant + payload, not propellant alone, so I made a mistake in adding the payload mass over again. Awesome. So the real numbers for 10 sample return missions are:

Sample return vehicle + samples: 640 kg
Return stage + sample return vehicle: 2315 kg
Descent stage + return stage: 3656 kg
Booster + descent stage + return stage: 11143 kg

So we’re really looking at between 12000 kg and 13000 kg. Still needs a heavy lifter, but not quite as dire as my original estimate.
