Teams Add Launch Abort System to Ready Orion for Artemis I

The Orion spacecraft for the Artemis I mission recently completed fueling and servicing checks while inside the Multi-Payload Processing Facility at NASA’s Kennedy Space Center in Florida. The capsule has now made it to its next stop on the path to the pad – the spaceport’s Launch Abort System Facility.

The Space Launch System (SLS) on top of the aircraft features an aerodynamic shape designed to pull crew away to safety. This capability was successfully tested during the Orion Pad Abort and Ascent Abort-2 tests and approved for use during crewed missions.

Teams with Exploration Ground Systems and contractor Jacobs will add parts of the launch abort system onto the spacecraft. Technicians will install four panels that make up the fairing assembly and protect the spacecraft from heat, air, and acoustic environments during launch and ascent. A launch tower will top the fairing assembly to house the pyrotechnics and a jettison motor. The system will also be outfitted with instruments to record critical flight data for later study.

With the successful demonstration of the system during previous tests, the abort motor that pulls the spacecraft away from the rocket and the attitude control motor that steers the spacecraft for splashdown during an abort will not be functional for the uncrewed Artemis I mission. The jettison motor is equipped to separate the system from Orion in flight once it is no longer needed, making Orion thousands of pounds lighter for the journey to the Moon.

Once the system’s integration is complete, teams will transport the spacecraft to the center’s Vehicle Assembly Building. It will then join the already stacked flight hardware and be raised into position atop the SLS rocket, marking the final assembly milestone for the Artemis rocket.

In 2021, Artemis I will test the Orion spacecraft and SLS rocket as an integrated system ahead of crewed flights to the Moon. Under Artemis, NASA aims to land the first woman and first person of color on the Moon and establish long-term lunar exploration.
