Space Launch System Lays a Solid Foundation

From the creator

The foundation has been poured for the Vertical Assembly Center (VAC) in support of NASA's Space Launch System (SLS). The VAC, measuring 170 feet tall and weighing 3 million pounds, will be one of the largest friction-stir-welding tools in the world. It took 90 truckloads of material to pour the 900 cubic yards of concrete to support the VAC. The tool will be used to weld together the barrel sections of the liquid oxygen and liquid hydrogen tanks for the SLS. (NASA/MSFC)
