The Orion crew module pressure vessel for Exploration Mission-2 is backed into the high bay at the Neil Armstrong Operations and Checkout Building at NASA's Kennedy Space Center in Florida on Aug. 24, 2018. The pressure vessel was transported in its Crew Module Transportation Fixture by super-wide transport truck from Michoud Assembly Facility near New Orleans. The pressure vessel is Orion's primary structure that holds the pressurized atmosphere astronauts will breathe and work in while in the vacuum of deep space. Inside the facility's high bay, the pressure vessel will be secured on a precision alignment tool to begin preparing it for flight.
