Yesterday, I traveled down to Marshall Space Flight Center here in Huntsville, Alabama to photograph the Friction Stir Welding Facility where they are fabricating the Common Bulkhead Domes for the ARES I second stage liquid Hydrogen and Oxygen tanks. This image depicts the dome section on the Robotic Welding Tool, which is the "top" of the liquid oxygen tank. The O2 and H2 tanks share this dome as top and bottom, respectively. A honeycomb structure will overlay this dome, and then the upper dome -the bottom of the H2 tank- will be attached over that.
