A figure showing the Apollo spacecraft's launch abort system. A diagram showing the configuration of Crew Dragon Endeavor during the Demo-2 mission.. Traditionally, spacecraft like Apollo and Soyuz have utilized solid-fueled "puller" launch escape systems, with the main spacecraft beneath a protective fairing attached to the escape system.
The Orion Multi-Purpose Crew Vehicle (Orion MPCV) is equipped with a launch escape system. Orion has several abort modes. Orion has several abort modes. Some of these may not use the LAS itself, but would use the second stage of the SLS, or even the Orion vehicle's own propulsion system (the Aerojet AJ10 engine) instead.
A launch escape system (LES) or launch abort system (LAS) is a crew-safety system connected to a space capsule. It is used in the event of a critical emergency to quickly separate the capsule from its launch vehicle in case of an emergency requiring the abort of the launch, such as an impending explosion.
This was an upgrade from the ILCS (Improved Launch Control System) capsules at the 341 MW that date to the late 1970s, and from the CDB capsules at the 90th and 91st missile wings. This was a major upgrade. The two launch control officers now sit side by side and must turn four launch keys to initiate a launch.
The most important change in making the Mercury-Redstone a suitable vehicle for an astronaut was the addition of an automatic in-flight abort sensing system. [11] In an emergency where the rocket was about to suffer a catastrophic failure, an abort would activate the launch escape system attached to the Mercury capsule, which would rapidly ...
The missile launch control environment also varied by system. Early missiles such as Thor and Atlas, relied on support facilities above ground, with crews protected in a shelter of some sort. Later systems were buried underground, either with the missiles located nearby (i.e. Titan) or a distance away (Peacekeeper, Minuteman).

The Crew Dragon In-Flight Abort Test (also known as Crew Dragon Launch Escape Demonstration [5]) was a successful test of the SpaceX Dragon 2 abort system, conducted on 19 January 2020. It was the final assessment for the Crew Dragon capsule and Falcon 9 launch system before they would be certified to carry humans into space . [ 6 ]
