The Launch Escape System (abbr. LES) is a tower which can be placed above a command pod to safely pull the crew off a rocket in case of an emergency. It behaves like a solid rocket booster as it is fueled by solid fuel and that it can only be activated once. Compared to other solid fuel boosters, the LES has high thrust and high efficiency. The thrust is slightly tilted to steer sideways and clear the rest of the rocket. This gives it significant potential for putting a lander back in orbit around the celestial body on which it has landed, provided there is no atmoshpere, and the body has low enough gravity.
Due to the low amount of solid fuel it only fires for five seconds. But, because it usually only pulls itself, some accessories like parachutes and a command pod, the LES's thrust-to-weight ratio is high. For example a combination of one Mk1-2 Command Pod, for which the LES fits the best, two Mk2-R Radial-Mount Parachute and the LES itself only mass 5.38 t which results in thrust-to-weight ratio of 14 on Kerbin.
