Accelerating from 0 to 60 then slowing down for a stop light is no problem for an ordinary automobile. But if you were piloting a rocketship, it wouldn't be so easy. Most rocket engines are designed to burn full-on (liftoff!) or full-off (coasting through space) with no in-between. And that can be a problem--namely, how do you land this thing? Throttling is crucial for a planetary lander. Descending from orbit is a unique balancing act, cutting engine power as the lander losses mass through...
