A European-built communications satellite, manufactured in secret for the Egyptian government, joined a European Space Agency exoplanet observatory aboard a Ukrainian Antonov An-124 cargo plane for a trans-Atlantic flight Wednesday to begin final launch preparations in French Guiana.

A pair of Earth-imaging satellites for the Italian military and a French-Israeli environmental monitoring project lifted off from French Guiana aboard a European Vega rocket at 0158:33 GMT Wednesday (9:58:33 p.m. EDT Tuesday).
