Posted By: Rob Posted On: Aug 25, 2008 Views: 1365 | How did they get back? I am not saying the moon landings were faked or anything but I have a question. Why is it that it took a monsterous great Saturn V rocket to get to the moon and only a very tiny little rocket to get back? I appreciate the moon's gravity is less but is the difference that great? |
Posted By: Keith Mayes Posted On: Aug 26, 2008 Views: 1359 | RE: How did they get back? You have already answered your own question correctly. Yes, its all down to the difference in gravity. It takes a tremendous amount of fuel to get into low earth orbit, just take a look at the Space Shuttle as an example of that, or any rocket that is launching a satellite. Once in orbit it does not take much fuel to get to moon, nearly all the journey is done just coasting, it only takes a few minutes of burn to get up to speed to get there. Coming back is simple. The moon's gravity is so weak it takes very little power to escape from it and the craft is soon caught by the earth's gravity and drawn home. In fact the main problem is slowing down using the earth's atmosphere to burn off the 25,000 mph speed. Hope that helps. Much more info on my main page including schematics and info on the Saturn V and Apollo craft. |

The rocket going "to" the moon had to get multiple capsules from the Earth to the moon and back. Also, that rocket, when it lifted off, had to lift all of the fuel. There is a HUGE difference between the size of rocket you need to take all the crap you need to go to the moon and back starting from the ground on Earth and the rocket you need to go from Lunar orbit back to the Earth. |

Read The final theory and update your misconceptions. Think about it. The concept of gravity is a false theory. Drop two objects right now and notice that no matter the mass/weight, they land at your feet at the same time. There is no gravity. The earth is constantly expanding. What we have been told to perceive as gravity is acceleration. Think about it. See any 101 science show about the solar system and it will tell you the universe is constantly expanding...so hey there! Duh...what about the earth? We are in the universe and we are constantly expanding as well. Once you have these basics straight, you will realize as you study the physics that we never went to the moon. Ipso facto, roger that: that is the truth. Sleep tight! |
Posted By: Keith Mayes Posted On: Nov 10, 2010 Views: 855 | RE: How did they get back? Yes, there is no gravity the Earth is expanding, it makes perfect sense now you mention it. Wonder why we aren't expanding any closer to the Moon? Hmmm, may be there is a tiny flaw in your expanding theory? Like it's total crap. |
