Video: Falcon 9 launch replays

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. 

United Launch Alliance’s first Vulcan Centaur rocket completed a critical test-firing of its Blue Origin-built BE-4 main engines Wednesday night, clearing one of two remaining technical hurdles before the launcher is cleared for its inaugural flight later this year.

A commercial rocket under development by Firefly Aerospace will conduct its first orbital test flight in 2019 from a launch pad at Vandenberg Air Force Base in California that will become vacant with the retirement of the venerable Delta 2 booster later this year, the company announced Tuesday.
