On December 8, 2010, SpaceX successfully completed a demonstration flight for NASA's Commercial Orbital Transportation Services (COTS) program with the flight of the first Falcon9 carrying a Dragon capsule.
The Dragon capsule completed two orbits and splashed down safely in the Pacific Ocean, making SpaceX the first commercial company to successfully launch and retrieve a capsule from low-Earth orbit.
SpaceX later revealed that Dragon carried a secret payload: a wheel of cheese.
