SpaceX's Falcon 9 is a reusable rocket designed to transport satellites and cargo to space. It was created by SpaceX, a company founded by Elon Musk to make space travel more affordable. The Falcon 9 is known for its two-stage design, which allows it to carry heavy payloads into orbit while returning safely to Earth for refurbishment and reuse. The rocket's first stage can land back on a drone ship or land pad after launch, significantly reducing costs. Since its first flight in 2010, the Falcon 9 has successfully completed numerous missions, including resupply missions to the International Space Station and launching astronauts into orbit.
