![]() It is positioned with its motors on top of the Orion crew module and designed to pull the crew module away from the rocket, rather than push it away with motors at the base, as some other escape systems are built to do. The tower-like abort structure is specifically built for deep space missions and to ride on a high-powered rocket. Fully jettisoning the entire LAS once it’s no longer needed frees Orion of thousands of pounds that will make it lighter for its trips into space. The jettison motor fires to separate the LAS from the spacecraft, and from this point, abort scenarios are handled by the engines in the service module. In the case of an emergency, the three solid rocket motors work together to propel the astronauts inside Orion’s crew module to safety: the abort motor pulls the crew module away from the launch vehicle the attitude control motor steers and orients the capsule then the jettison motor ignites to separate the LAS from the crew module prior to parachute deployment.ĭuring a normal launch, once the SLS clears most of the atmosphere, the job of the LAS is done. The launch abort tower includes the system’s three motors. The fairing assembly is a shell composed of a lightweight composite material that protects the capsule from the heat, wind, and acoustics of the launch, ascent, and abort environments. ![]() The LAS is divided into two parts: the fairing assembly and the launch abort tower. It can activate within milliseconds to pull the vehicle to safety and position the crew module for a safe landing. ![]() Orion’s launch abort system (LAS) is designed to carry the crew to safety in the event of an emergency during launch or ascent atop the agency’s Space Launch System (SLS) rocket. NASA expects to take advantage of the unique exploration capabilities of both SLS and Orion and emerging commercial capabilities to build and support the Gateway. It gives us opportunities to test new tools, instruments, and equipment to expand humanity into our solar system. The Moon is the proving ground for sending astronauts to Mars. Orion’s missions will span multiple phases, as part of NASA’s framework to build a flexible, reusable, and long-duration infrastructure that will last multiple decades and support missions of increasing complexity. It will provide protection from solar radiation and high-speed entry into Earth’s atmosphere, as well as advanced and reliable technologies for communication and life support. Orion is specifically designed to carry astronauts on deep space missions father than ever before. NASA’s Artemis program is leading the charge to land the first woman and first person of color on the surface of the Moon, and Orion is the spacecraft that will carry astronauts from Earth to the lunar vicinity and return them back home. It is currently the only spacecraft capable of crewed deep space flight and highspeed return to Earth from the vicinity of the Moon. The Orion spacecraft is built by NASA and prime contractor Lockheed Martin.
