A SpaceX rocket has lifted off from Cape Canaveral in Florida carrying the world 's first all-electric satellites . The two spacecraft will reach their desired orbit in them months and will maintain itusing ion propulsion . Without chemical fuel their weight was drastically reduced , allowing both to be launched on the same rocket rather than costly separate launches .
