The first full-scale model of the P120C rocket motor that will propel #Ariane6 and #Vega-C into orbit was cast and filled with inert propellant for intensive testing in Europe’s Spaceport in French Guiana in September 2017. It is the largest single casting of a solid propellant motor ever achieved. This photo was taken by a camera inside the casing.
