Live coverage: SpaceX’s next Falcon 9 rocket test-fired in Florida

A commercial cargo craft owned and operated by Orbital ATK wrapped up a two-day journey to the International Space Station on Tuesday, delivering ice cream and pizza for the lab’s six-person crew and hardware for a slew of research experiments, including CubeSats slated for orbital deployments in the coming weeks.

A U.S.-built commercial communications craft owned by Intelsat and a new node for Europe’s laser data relay satellite network rocketed into orbit Tuesday from Kourou, French Guiana, on top of an Ariane 5 rocket.

SpaceX hopes to take a giant leap forward in rocket technology a few minutes after Friday’s scheduled launch of a Falcon 9 booster taking up 2.5 tons of critical supplies and experiments to the International Space Station.
