  • Apollo Saturn V Launch Clips | 60fps | NASA Camera Views in Realtime
    A compilation of Apollo Saturn V launches from NASA engineering and documentation cameras Most of the engineering footage was recorded in slow motion using high speed 16mm film cameras during Apollo 8, 11, and 12 to document and analyze the missions
  • Cost comparison in todays dollars STS vs. Saturn V
    A Saturn V launch definitely costs more in constant dollars However the Saturn lifts about 5x the useful payload, so even if the Saturn cost 5x as much per launch, the cost per pound would be about the same
  • Power for Apollo: Saturn V - NASASpaceFlight. com
    The Saturn V's design stemmed from the designs of the Jupiter series rockets As the success of the Jupiter series became evident, the Saturn series emerged C-1 to C-4 Between 1960 and 1962, the Marshall Space Flight Center (MSFC) designed a series of Saturn rockets that could be used for various Earth orbit or lunar missions
  • We Can’t Rebuild Saturn V, But… - forum. nasaspaceflight. com
    The logic behind Shuttle-era "why don't they just bring back Saturn V" was the comparison with the cost capacity cadence of STS But today, even its self-proclaimed reasoning doesn't apply Today, the comparison would be with SLS But SLS already has superior rivals
  • The Saturn V thread - NASASpaceFlight. com
    The Saturn V thread Different beasts and as such people don't like to compare But the full Saturn V, remember there were more versions, was 7 5 million lbs thrust from liquid propellant and the STS is 7 7 million lbs thrust, 6 6 million of that coming from the SRBs, although again you have to then take a number of factors into account A shuttle launch is very loud and bright, but nothing
  • This is why we couldnt rebuild the Saturn V. . .
    Uprated Saturn V (B) improved F-1 J-2 engines, composite and Aluminium Lithium materials -- 150-to-160 tons It seems to me it might be quicker, cheaper and easier to just go ahead with an optimised version of the Ares V if you want real Heavy Lift After all, we're closer to Ares V than we are Saturn V
  • Apollo Launch Tower For The Saturn V
    Before the Saturn V ever moved, it was sustained by the launch tower Electrical power, cryogenic propellants, environmental control gases, and high-fidelity instrumentation all flowed through engineered umbilical arms that connected the rocket to the ground
  • The Saturn-V Propulsion System
    The Saturn-V Propulsion System Dec 5, 2025 Go inside the Rocketdyne J-2 engine — the restartable hydrogen–oxygen engine that powered Apollo’s upper stages Discover how the S-IVB settled its cryogenic propellants with APS ullage thrusters, conditioned the engine with long hydrogen bleeds, and ignited using its augmented spark igniter to fire again in the vacuum of space A detailed look
  • Why cant we build the Saturn V again? - NASASpaceFlight. com
    We have the detailed design of Saturn V and Apollo, and also the lander although Saturn V could be re-designed (re-invented) to better serve the new mission, Apollo and the lander are totally inappropriate for the project
  • Saturn V modifications needed for maximum discretionary LEO payload?
    IOW the Saturn V couldn't have launched a 128,350 kg satellite (139,750 kg total LEO mass - 11,400 kg SIVB dry mass) What modifications would have been necessary to life the maximum discretionary LEO payload? Did the Skylab numbers include the shroud? Also Skylab went to a 50 degree inclination which is a performance hit
