With India's launch of its first unmanned lunar spacecraft following closely on the heels of China's first spacewalk, we are reminded just how urgently the United States must revitalize its space program if we are to remain the undisputed leader in space, science, and technology.

My comprehensive plan to revitalize the space program and close the gap between the Space Shuttle's retirement and its next-generation replacement includes $2 billion more for NASA - but more money alone is not enough. We must not only retain our space workforce so that we don't let other countries surpass our technical capabilities; we must train new scientists and engineers for the next generation. My comprehensive space policy focuses on reaching new frontiers through human space exploration, tapping the ingenuity of our commercial space entrepreneurs, fostering a broad research agenda to break new ground on the world's leading scientific discoveries, and engaging students through educational programs that excite them about space and science.

As a child, I remember sitting on my grandfather's shoulders and watching the Apollo astronauts return from a splashdown to Hickam Air Force Base, dreaming of where they had been. It inspired my imagination and gave me confidence in what we as Americans could achieve. It's time for a space program that inspires our children again. As President, I will lead our space program boldly into the 21st Century - so when my daughters, and all our children, look up to the skies, they see Americans leading the way into the deepest reaches of our solar system.
