The SpaceX Falcon 9 rocket sitting on the pad at Kennedy Space Center doesn’t look too different from its predecessors, but it represents the culmination of two decades worth of rocket engineering at Elon Musk’s space company.

The fifth iteration of the Falcon 9 rocket, called a “Block V,” it is intended to be the final version of the company’s workhorse orbital lifter, capable of being reused ten times or more with minimal refurbishment between flights. Today, it will lift a Bangladeshi satellite into orbit, but its final purpose is to show NASA it is safe to carry astronauts to the International Space Station next year.
