Space is a vacuum with no air resistance from "summary" of Rocket Science: A Beginner's Guide to the Fundamentals of Spaceflight by Andrew Rader
In space, there is no air. This may seem like a simple statement, but it has important implications for spaceflight. On Earth, we are used to the presence of air all around us. We feel its resistance when we move through it, whether we are walking, driving, or flying in an airplane. This resistance is known as air resistance, and it is a force that opposes motion. When a rocket is launched from Earth, it has to overcome the force of gravity, as well as the force of air resistance. This is why rockets are designed to be aerodynamic, to minimize the effects of air resistance as they travel through the Earth's atmosphere. But once a rocket reaches space,...
