NASA and SpaceX have set their third launch date at May 19 for the first privately built and funded spacecraft to rendezvous with the International Space Station. This could be the beginning of a new era of space travel - from the private sector.
For this mission SpaceX is planning to launch its Dragon capsule, loaded with 1,200 pounds of cargo, with its own rocket, the Falcon 9. Elan Musk is the owner and chief engineer of the company.
