NASA's Constellation program, established in 2005, continues its work toward the building the future of manned space exploration in the U.S. The first test flight of the Ares I-X rocket - a functional mockup of the actual Ares I rocket, similar in shape and mass - is scheduled for July, 2009. The stimulus bill just passed by the U.S. Congress will be sending an additional $1 billion to NASA, $400 million of which is for its manned space program. Engineers are now busy refitting old facilities, running tests, building the infrastructure and working towards a planned first launch of a crew to the International Space Station in 2014. Collected here are photographs of various parts of the Constellation program coming together, including parts of the Orion crew vehicle, the Ares I and Ares V rockets, and supporting systems.
