Hypergolic (hydrazene) engines are typically used     only on interplanetary probes     to slow down (braking) when returning to Earth     to provide thrust for launches     for maneuvering and making attitude changes while in space

Newton's First Law of Motion

If a very smooth ball is rolled down an inclined surface with zero friction, the ball will continue to roll indefinitely for an infinite time, in an attempt to reach to the same height on the opposite hill!
