Four European navigation satellites fastened on top of an Ariane 5 rocket lifted off from Kourou, French Guiana, at 1836:07 GMT (1:36:07 p.m. EST) Tuesday to propel the Galileo navigation network closer to global service. The Ariane 5’s upper stage delivered the spacecraft to a circular orbit more than 14,000 miles above Earth around four hours after launch.
