Most who grew up during the days of the space race were promised a future with moon colonies, orbital space stations, and routine travel to the stars. But that future has always been elusive, since it has long depended upon shifting Congressional priorities and timid funding currently, NASA's budget is about $21 billion, or 0.49% of the federal budget.
