Live coverage: Ariane 5 soars into space from Kourou

Two British-built reconnaissance satellites, one designed to test new radar imaging technology and another to collect high-resolution optical imagery, arrived in orbit Sunday after a successful liftoff aboard an Indian Polar Satellite Launch Vehicle.

SpaceX test-fired a Falcon 9 rocket for the second time Saturday after replacing a valve following an earlier static fire test Wednesday. The move has postponed the Falcon 9 rocket’s launch with the Amos 17 commercial communications satellite to no earlier than Tuesday.

Ten more satellites for Iridium’s commercial communications network flew into orbit Friday aboard a Falcon 9 rocket from Vandenberg Air Force Base in California, raising the total number of upgraded Iridium spacecraft launched to 50 and clearing the way for liftoff of a SpaceX supply ship Monday from Cape Canaveral to the International Space Station.
