Orion Meets SLS: L3Harris Technology Ready to go to the Moon

NASA’s Artemis II mission is one step closer to launch after the Orion spacecraft was stacked atop NASA’s Space Launch System (SLS) rocket inside the Vehicle Assembly Building at Kennedy Space Center. This milestone marks the first time the full Artemis II stack has come together.

The Orion spacecraft is designed to take crews to deep space destinations and return them safely to Earth. Four astronauts – Commander Reid Wiseman, Pilot Victor Glover and Mission Specialists Christina Koch and Jeremy Hansen – will call Orion home during their 10-day Artemis II mission, which will send them on a journey around the moon and back.

L3Harris plays a critical role in Orion’s capabilities, providing 22 engines and motors that enable precise maneuvers in space; the audio system that connects astronauts to each other, mission control and the world; as well as composite overwrapped pressure vessels that support the operation of the spacecraft during its journey. These technologies are essential to Orion’s ability to carry astronauts farther into space for longer periods of time. 

“This is the first time since 1972 that we've assembled a rocket and spacecraft that will carry humans to the moon's vicinity,” said Kristin Houston, President, Space Propulsion and Power Systems, Aerojet Rocketdyne, L3Harris. “This is an exciting moment for the Artemis II mission, and the spacecraft’s name ‘Integrity’ is fitting, as it embodies the trust, precision and resilience required to make this mission a success.”

The Orion spacecraft for NASA’s Artemis II mission, fully assembled with its launch abort system, is lifted ontop of the Space Launch System (SLS) rocket in High Bay 3 of the Vehicle Assembly Building at Kennedy Space Center in Florida.

Preparing for Launch

For the next several months, the Artemis II vehicle will undergo rigorous integrated testing to ensure all systems work seamlessly together. These tests will prepare the spacecraft and rocket for their ultimate mission: carrying astronauts around the moon and back.

“With Orion now securely on top of the core stage, the Artemis II stack is a powerful symbol of our nation’s commitment to exploration and pushing the boundaries of what’s possible – an especially fitting milestone as we prepare to celebrate the 250th anniversary of America’s founding next year,” added Houston. “Stacking Orion onto the SLS rocket is not just a technical milestone, it represents the incredible teamwork and innovation that are driving the future of human space exploration.”
