Watch the Falcon 9 launch from pad 39A

A replay of the United Launch Alliance Atlas 5 rocket launching the Orbital ATK’s commercial Cygnus cargo freighter to the International Space Station from Cape Canaveral, Florida.

Maritime and aviation warning suggest a launch no earlier than Jan. 10, but SpaceX hasn’t formally announced its target launch date. Flight 7 will also feature the first launch of a Block 2 Starship upper stage.

SpaceX Starship is set to propel itself into the record books today on its maiden flight, becoming the tallest, heaviest and most powerful rocket ever launched by humankind into space, topping a role call of famous and history-making heavy-lift launch vehicles including the mighty Saturn 5 that first took humans to the moon.
