Over the years, SpaceX has had quite a number of impressive triumphs. SpaceX is the first private company to return a spacecraft from low earth orbit. It is also the first to reuse the first stage of the rocket (as a way to cut costs) and have a successful launch with it. It is the ambition of SpaceX to design the "most powerful operational rocket in the world."
Dragon spacecraft is a capsule developed to carry passengers and supplies to the International Space Station. Dragon made history when it came back to earth. With the Falcon 9 rocket and landing, it was critical to the company's agenda to build cheap rockets. One of the most expensive issues with the previous spacecraft is that they weren't reusable. This issue was an enormous hurdle with their plans.
SpaceX has a number of accomplishments under its belt. They have a number of first among space programs. One is that they were the first privately funded rocket that is liquid-fueled to reach orbit. This happened on September 28, 2008, with Falcon 1 flight 4.
On December 9, 2010, they became the first private company to launch a spacecraft, orbit it, and recover it. They did so with SpaceX Dragon. Along with that, they achieved the first landing of the orbital rocket on land. This happened in 2015 with their Falcon 9 flight 20. SpaceX is also the first to reuse payload fairing.
