10 Years Ago Today, SpaceX's Falcon 9 Blasted Off for the First Time

SpaceX's Falcon 9 rocket has certainly earned its place in history. Falcon 9 is the first orbital class rocket to be reused and the first commercial rocket to ferry human passengers to the ISS.

Each two-stage Falcon 9 rocket is powered by a first stage with a suite of nine Merlin engines, which use kerosene (RP-1) and liquid oxygen propellants, and a second stage powered by a single Merlin vacuum engine. The 230-foot-tall rocket weighs a staggering 1,207,920 pounds and can shuttle a payload weighing 50,265 pounds to low-Earth orbit and a payload of 8,860 pounds to Mars. At sea-level, Falcon 9 can generate a whopping 1.7 million pounds of thrust.

June 4th marks 10 years since the rocket's inaugural test flight. Since 2010, Falcon 9 has launched 84 times and has safely returned to Earth 45 times. Thirty-one of those rockets have been recycled and flown again. Falcon 9's reusability revolutionized spaceflight, making it cheaper and more efficient.

To celebrate Falcon 9's big day, we're looking back at ten memorable moments in Falcon 9 history.
