Step:
1. is no exception and is far more difficult. The rocket, the fuel and payload represents the three main components. At launch, it can take the fuel up 90% of the total weight, while 10% of the rocket and payload. Is the price to accelerate to 5 miles per second, and why the rockets are so big when the payload can be as small as a few people. At this speed the rocket less than half his weight, half of its mass and orbits the Earth. In preparation for the second step, get rid of rocket parts of himself that led him here.
2. Launch of the low Earth orbit to high Earth orbit.
This step requires the rocket to accelerate again to go even higher, much higher than in the previous step. But after less than half the mass, there is less to carry. Plus, the more you get, the weaker gravitational pull of the Earth becomes, making the task easier.
3. Launch of the High Orbit transfer orbit.
Three factors are taken into account in determining the speed of this journey, in chronological order: the Sun the Earth, the Moon. The speed must be sufficient to leave the Earth's gravity altogether, with some remnants of speed. Then, the great distance of the moon, is actually calculated as an orbit around the sun. This is because the Sun's gravity dominates the gravity of Earth and Moon.
The speed of the latest revision is the Moon. Fuel is expensive and cumbersome, unless you take the better. But the moon is much smaller than Earth, so its gravity is much weaker. So, just fly slow enough to allow the moon to catch you in their severity. That's why it takes three days to travel to the moon. Do not ride faster, the rocket fuel necessary to further decrease. No brakes in space.
4. Start the orbit of the Moon Transfer Orbit.
When you are close to the Moon is in orbit around the sun, they should avoid the moon. Gravity's pull increases when approaching the moon, so you can speed up a bit '.
5. Low Moon Orbit launch lunar surface.
Now, for landing on the moon. You need to slow down or accelerate in the opposite direction of your orbit. Therefore, although this step is still a "Go". When finished,
