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.

The commercial Cygnus freighter carrying over 7,000 pounds of food, supplies and science experiments completed a flawless rendezvous with the International Space Station on Saturday morning. It was captured by the robotic arm at 6:51 a.m. EDT (1051 GMT).

Another batch of Starlink Internet satellites shared a ride into orbit with three of Planet’s SkySat Earth-imaging satellites on a SpaceX Falcon 9 rocket Saturday. The Falcon 9 lifted off at 5:21 a.m. EDT (0921 GMT) from pad 40 at Cape Canaveral Air Force Station.
