MarkWhittington writes "2007 marks the fiftieth anniversary of the Space Age, agreed by most to have begun with the launch of the first artificial Earth satellite, Sputnik, on October 4th, 1957. While some are taking stock of the last fifty years of space exploration, noting what has been accomplished and, more importantly, what has not been accomplished, others are wondering what the next fifty years might bring."
