Commercial Resupply

A little more than two years after the end of the Space Shuttle Program, SpaceX and Orbital ATK (now Northrop Grumman) began successfully resupplying the space station with cargo launched from the United States. The companies developed the rockets and spacecraft through public-private partnerships under the agency’s program, an initiative that aimed to achieve safe, reliable and cost-effective commercial transportation to and from the space station and low-Earth orbit.
