It is an historic milestone as this second commercial partner's demonstration mission reaches the ISS, and I congratulate Orbital Sciences and the NASA team that worked alongside them to make it happen. "Orbital joins SpaceX in fulfilling the promise of American innovation to maintain America's leadership in space. As commercial partners demonstrate their new systems for reaching the Station, we at NASA continue to focus on the technologies to reach an asteroid and Mars. "The international crews aboard the station are working hard on the science and technology demonstrations to help us reach new destinations, and the expanded cargo transportation capability Orbital has now demonstrated strengthens that work. "Under President Obama's leadership, the nation is embarking upon an ambitious exploration program that will take us farther into space than we have ever traveled before, while helping create good-paying jobs right here in the United States and inspiring the next generation. "Congratulations again to the Orbital and NASA teams for achieving another important milestone on this exciting path. Godspeed, Cygnus, and here's to many more successful flights." Assistant to the President for Science and Technology John P. Holdren:"Space history was again made today with the berthing of Orbital Sciences' cargo-carrying Cygnus spacecraft to the International Space Station. Now two American companies have proven they are capable of delivering cargo to the space station. "This mission is exactly what the President had in mind when he laid out a fresh course for NASA to take Americans deeper into our solar system while relying on private-sector competition to lower the cost of ferrying astronauts and cargo to low-Earth orbit and the International Space Station. It's essential we maintain competition and fully support this burgeoning and capable industry to get U.S. astronauts back on American launch vehicles as soon as possible.
