Crew Space Transportation System

Crew space transportation system is like a really fancy kind of elevator! It helps people get to space, which is really far away. Some people use it just for fun, but mostly it's for scientists and astronauts to get to the International Space Station. The system is like a tube with a big round car inside it. The car is connected with a big machine on the ground that helps it move up and down. The machine works like a giant rocket, pushing the car up and down faster than anything else. As it moves up and down, it brings people and things to space and back to the ground. So it's kind of like an elevator for space!
