A retrorocket (short for retrograde rocket) is a rocket engine providing thrust opposing the motion of a vehicle, thereby causing it to decelerate. They...

Soviet, U.S., Chinese and Indian spacecraft have used braking rockets (retrorockets) to make soft landings and perform scientific operations on the lunar...

spacecraft was basically a Vostok spacecraft that had a backup, solid-fueled retrorocket added to the top of the descent module. As it was much heavier, the launch...

Vostok's retrorocket could fail and leave the cosmonaut stuck in orbit. It was too late in the spacecraft's design phase to add a backup retrorocket but it...
