Shuttle: launch cost $600M, payload 24 tons max (+7 astronauts) = $25M per ton to ISS --- Falcon/Dragon: COTS+CRS funds to SpaceX $2.1 Bn / 20 tons (and ZERO astronauts) = $105M per ton to the ISS --- so, the "cheap" Falcon/Dragon price-per-ton-to-ISS is OVER FOUR TIMES HIGHER than the "expensive" Shuttle!!! --- also, send seven astronauts with a Soyuz (instead of a Shuttle) will cost $51M per seat x 7 = $357M --- |
