Gaetano Marano at his Ghostnasa website has leaked, from a European Space Agency website, an EADS Astruim presentation that was part of a 8 July lunar architecture, industry day
So it would appear that a European Moon mission would require four launches. Two for the lander and its Earth departure stage (EDS) to be sent into orbit around the Moon, probably to dock with an existing lunar station and another two to launch the crew space transportation system and its EDS, which would dock in Earth orbit before going to the Moon.
ESA’s interest in a cislunar space station was already known and the use of such a station as a fuel depot seems to have heavily influenced the European Moonship design with its 16,000kg mass that is substantially less than the NASA Orion crew exploration vehicle’s
So from this it would seem that Astrium is proposing a hypergolic service module engine and probably crew capsule reaction control system. It certainly overcomes the development work that NASA is now undertaking to find a way of storing cryogenic fuels for long durations
