SpaceX designs, manufactures and launches advanced rockets and spacecraft, and is the world's fastest-growing provider of launch services. It is the only private company ever to return a spacecraft from low-Earth orbit, which it first accomplished in December 2010. SpaceX is also the first private company to attach a spacecraft to the International Space Station, exchange cargo payloads, and return safely to Earth - a technically challenging feat previously only accomplished by government space programs. SpaceX operates a Rocket Development Facility in McGregor, Texas which has grown to over 250 employees since starting operations in 2003. The Brownsville facility will launch commercial satellites.
