Rocket Staging

The practice of discarding spent tanks and engines during ascent so the rocket no longer has to accelerate empty mass. Staging sidesteps the rocket equation's steep penalty on mass ratio and is how essentially every orbital launch vehicle reaches space — from the Saturn V's three stages to the Falcon 9's two.
