and thus no air resistance on the moon but does that really explain the small size of rockets needed to escape the moons orbit?That is the only thing
i could never figure out about the moon landing and it always bugged me.
wel, as jj said you pretty much answered it yourself and he did a mighty fine job elaborating. so here's my spin/addition to it...
the saturn v rocket, on earth weighs in at over 6 million
pounds. the rocket engines on the first stage was just over 18 feet in diameter.
the entire lunar module, on earth, weighs on at about 33,500 pounds. that's about 179 times less the weight of the entire saturn v rocket. i don't
know and have been able to locate any specifications for the lunar module's engine though.
on the moon, though, the lunar module would only weigh about 5,600 pounds, due to to the lesser gravity. also, with the near lack of an atmosphere
there is less resistence. that's why it wouldn't need anywhere as powerful of engines.
