Air Products and Chemicals (APD) said Thursday it has completed the first fill of the hydrogen sphere at the National Aeronautics and Space Administration's Kennedy Space Center on Merritt Island, Florida.

NASA uses liquid hydrogen combined with liquid oxygen as fuel in cryogenic rocket engines, the company said. It delivered over 730,000 gallons of liquid hydrogen to the agency's new sphere.

The hydrogen will be used to fuel NASA's Artemis missions, which aim to return humans to the Moon, Air Products said.
