Tanking Operations Begin

Liquid oxygen and RP-1 fuel are starting to flow into the Falcon 9 rocket’s first- and second-stage propellant tanks and the terminal countdown has started.

The Falcon 9 — named after the Millennium Falcon spacecraft from the Star Wars film series — stands 229 feet tall and measures 12 feet wide. Its nine first-stage Merlin engines generate a combined 1.53 million pounds of thrust at liftoff.
