Rocket assembly in Florida

Teams finish integrating the interim cryogenic propulsion stage to the Space Launch System launch vehicle stage adapter inside the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. The four-story high propulsion system, built by Boeing and United Launch Alliance, is an RL10 engine that will enable the Orion spacecraft to build up enough speed for the push toward the Moon during the Artemis II crewed test flight.
