Mission Modular

Mission Modular
Space engineers, could answer the question Methis?

This is just one of several questions I have about space technology. I read that in the first manned moon mission, Apollo 11 Saturn V was performed in outer space. Why was it needed more of a spaceship Tak for this? Could not Apollo 11 alone achieve this? I also read that about the moon landing, the lunar module Eagle separated from his command module Columbia, which orbited the Moon. Why the command module Columbia requires that the orbit of the moon? And since the command module Columbia was moving, how Lunar reenter modular (Did Neil Armstrong and Buzz Aldrin say to each other: "Look, here comes Michael, so be prepared for the ship's hold with hands …"?

The Apollo 11 mission was carried out using all types of equipment. There was no separate spacecraft called Apollo 11. It was not launch vehicle, the command module, lunar excursion module, and re-entry capsule. In order to raise much the hardware of the surface land and still have enough fuel to reach the moon and back, you need a large launch vehicle. This is because the weight you are lifting, the more fuel it needs – and more fuel it needs, the heavier the vehicle. Is a function that tends to lead to larger and larger reinforcements you want larger spacecraft and larger. Basically, sweat bullets to eliminate every ounce of extra weight over the upper stages, because each ounce meant more pounds of fuel and further strengthening. That is why the Saturn V was developed as the launch vehicle. The command module, for example, probably did not have enough momentum to rise very far from land in the strong gravity of the earth. It was designed for use in low-gravity environment of the lunar orbit. In the Similarly, if the command module had landed on the lunar surface that would have required more fuel to start again. This has been made heavier would have required that the Saturn V to carry more fuel, making it heavier, and so on. It's a bit of a balancing act. Remember that even the excursion module lunar far left of your weight on the lunar surface – only the top half in reverse to return and meet with the command module. The way was out was actually the most efficient and safe to do so, and was developed during the years of reviewing the different options by NASA. The appointment and docking maneuvers were made during the Gemini and early Apollo missions. The locking hardware features, matching hatches, as well as the specific methods used on Apollo 11 were well known for years before being used above the moon. , Affect a simple application of the laws of Newton and good design practices but they were simple to the point of being elementary. It took a lot of hard work by thousands of people behind the scenes to make it look so easy. It was not so easy but it certainly worked very well.
