Live coverage: Two satellites lift off aboard Ariane 5

Egypt’s first military communications satellite and a powerhouse spacecraft to beam Internet signals to airline passengers and maritime vessels across Europe and the Middle East rocketed into orbit Tuesday on the 250th flight of an Ariane launcher. 

Bad weather offshore has forced SpaceX and NASA to delay Thursday’s planned launch of the Crew Dragon by a day. Better conditions are expected on Friday for a 5:49 a.m. EDT (0949 GMT) liftoff from the Kennedy Space Center.

A United Launch Alliance Atlas 5 rocket blasted off from Cape Canaveral at 11:05 p.m. EDT (0305 GMT) tonight to send Orbital ATK’s commercial Cygnus cargo freighter to the International Space Station. Follow the mission in our live journal.
