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...

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...

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...

Aldrin had already set foot on the Moon when Luna 15 fired its main retrorocket engine to initiate descent to the surface at 15:47 UT on 21 July 1969...
