Behold the new welding “tool” at the Vertical Assembly Center in NASA’s Michoud Assembly Facility in New Orleans, the largest spacecraft welding tool in the world for the largest rocket ever, the Space Launch System that will take us one day to Mars.
This thing is 170-foot-tall and 78-foot-wide. It will put together the main stage for the SLS, 200 feet tall (61 meters) with a diameter of 27.6 feet (8.4 meters)—”this giant cryogenic liquid hydrogen and liquid oxygen that will feed the rocket’s RS-25 engines.”
