Ask an Explainer

Q:

Why are spacecraft fast?

A:

Spacecraft, unlike airplanes, do not have to deal with the force of drag created by air on our planet. Since spacecraft fly in space where there is no air, they can reach higher speeds and maintain those speeds much more easily without dealing with the friction that drag creates.
