Photo: 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 51.82m-tall and 23.77m-wide. It will put together the main stage for the SLS, 61m tall with a diameter of 8.4m — “this giant cryogenic liquid hydrogen and liquid oxygen that will feed the rocket’s RS-25 engines.”
