Earth reentry friction compression
WebBecause friction is a completely free way to slow a spacecraft down. In space, the only way to slow down is to burn fuel in the opposite direction you're moving. Using the air to slow down instead means you don't need to bring as much fuel, which means you can bring a heavier payload.
