Not Because It Is Easy, But Because It Is Hard

摘要

Nearly a half-century ago, when U.S. President John F. Kennedy said, "We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard," he inspired a space program and a nation to do historic things.rnSoon, perhaps as early as this week, a very different kind of hard but historic thing in spaceflight is going to take place, and in full public view. It's the inaugural test flight of the Space Exploration Technologies Corp. (SpaceX) Dragon capsule for NASA's Commercial Orbital Transportation Services (COTS) program.
