The next pair of spacecraft to join Europe’s Galileo navigation system are positioned for liftoff late Thursday aboard a Soyuz rocket. These photos chronicle the preparation of the satellites for launch at the Guiana Space Center.

A SpaceX Falcon 9 rocket is set for launch from Kennedy Space Center in Florida on Monday with a mobile broadband communications satellite for Inmarsat.

After a two-day delay caused by unfavorable high-altitude winds, an Ariane 5 rocket lifted off Saturday at 3:40 p.m. EST (2040 GMT) from French Guiana with communications satellites for DirecTV and India.
