A high-throughput communications satellite developed as a joint venture between Telesat and APT Satellite lifted off on top of a SpaceX Falcon 9 rocket at 12:45 a.m. EDT (0445 GMT) Monday from Cape Canaveral, following a delay to wait for storms to clear the Florida spaceport.

Two U.S.-built communications satellites rode the 100th European-made Ariane 5 rocket into orbit Tuesday from the jungle of French Guiana. Liftoff occurred at 2238 GMT (6:38 p.m. EDT) after a 45-minute delay caused by a range technical problem.

The United Launch Alliance Atlas 5 rocket, standing 194 feet tall and and weighing 950,000 pounds, unleashes 1.5 million pounds of thrust from its main engine and two side-mounted boosters at 8:37 a.m. EDT today to launch the National Reconnaissance Office’s NROL-61 satellite from Cape Canaveral.
