A liquid oxygen tank confidence article for NASA's new rocket, the Space Launch System, completes final welding on the Vertical Assembly Center at Michoud Assembly Facility in New Orleans. This is the first glimpse of what one of the two tanks will look like that make up the SLS core stage. Towering more than 200 feet tall with a diameter of 27.6 feet, the core stage will store cryogenic liquid hydrogen and liquid oxygen that will feed the vehicle’s RS-25 engines.
