Airgas, an Air Liquide company, supplies mission-critical high-pressure nitrogen for NASA’s historic Artemis II launch

Air Liquide is proud to announce Airgas’ continued role in the advancement of American space exploration through the successful support of NASA’s Artemis II mission. As the first crewed flight of the Artemis program, this 10-day journey has sent a four-person crew around the Moon, marking the first human travel to lunar space in over 50 years and paving the way for a permanent lunar presence. The space sector is one of the multiple areas of development for the Group, which is ideally positioned thanks to its historical footprint in the United States.

As part of a long-standing collaboration between Air Liquide and NASA that spans more than 50 years, Airgas supplied the critical high-pressure nitrogen required for launch operations at the Kennedy Space Center. This nitrogen gas supply was managed and delivered by the Airgas facility in Merritt Island, Florida.

The Airgas team leveraged its reliable infrastructure and technical expertise at the Merritt Island site to meet the rigorous demands of the Artemis II launch, achieving the highest flow rates to support the Space Launch System (SLS) rocket during its final countdown and liftoff.

From the provision of essential ground-based infrastructure, cryogenic equipment and systems for launch vehicles and satellites, to the supply of cryogenic fluids and high-purity rare gases for propulsion, the Group is a key enabler in the comprehensive supply chain of space exploration. Airgas provides vital high-flow nitrogen pumping and pipeline services for critical rocket tests and launches, complemented by dedicated onsite supplies and Air Separation Units (ASUs) to enable the consistent, high-specification gas supply demanded by specialized space applications.

Marcelo Fioranelli, Chief Executive Officer of Airgas, stated: “The Artemis II mission is more than just a return to the Moon, it's a testament to what we can achieve when we aim for the stars. At Air Liquide, we are honored to fuel this historic endeavor, knowing that our reliable supply of nitrogen plays a crucial role in enabling this monumental leap forward. This mission, much like our commitment to every customer, is about filling our potential - pushing boundaries, embracing innovation, and achieving what was once unimaginable. We are proud to support NASA as they inspire the next generation of deep space explorers.”
