“ NASA HAS A planet-size problem on its hands. Ironically, its source is here on Earth: Congress, which has the penny-wise but pound-foolish policy of releasing just a trickle of funding to the space agency every year, hobbles many of NASA’s mission goals that require thinking past a two-year House or six-year Senate term. This hurdle has repercussions that can be felt across the solar system.”

Republicans have a science problem.
