Soyuz

Flying for the 10th time from a tropical launch facility along the South American coastline, a Russian Soyuz rocket lifted off Dec. 18 and streaked through partly sunny skies with four satellites to extend the reach of the O3b Networks, a company founded to bring broadband to the world’s most remote and impoverished countries.

Four satellites designed to broadcast high-speed Internet signals to the developing world are mounted on top of a Russian-made Soyuz rocket for liftoff Thursday from the Guiana Space Center in South America. See photos of the quartet of satellites undergoing launch preparations.
