     If spaceships were launched from space or from the moon, the absence of weight would permit the ships to be launched with great speed at reduced pressures. A relatively small explosion would be enough to send a ship off at a very fast rate. And, since there is no atmosphere in space as there is on earth, the spaceship would meet with no resistance. To illustrate this point, remember how strong the wind feels if we are traveling fast in a car; then imagine a car traveling through an area where there is no wind. The windless condition is comparable to the condition in outer space.
     The first astronaut to walk in space, Leonov, and his companion, Beliaiev, began making preparations for the walk as soon as their spaceship was launched. The spaceship was equipped with a double door, which was fitted with bellows between the ship and the outside. This made it possible for the astronaut, in his space suit with oxygen supply, to go first from the air-filled ship to the bellows. Then the air was let out of the bellows, and, while the man stepped outside, the air inside the ship remained at normal pressure. If the door had opened directly into space, the air in the ship would have rushed out and been lost when the door opened.
     Leonov and Beliaiev practiced testing the doors several times after they had begun revolving around the earth. When the time came for Leonov to go out, his companion helped him attach the cable that was to keep him from floating away from the ship. Then Leonov entered the bellows, and the door closed behind him. As the air was let out of the bellows, he felt his suit swell up because of the air pressure inside.
