Praise: Neil deGrasse Tyson, advocate for education and NASA

Astronomer and author Neil deGrasse Tyson's testimony on Wednesday before the United States Senate ran about twenty-five minutes including the Q & A.  In the testimony, Dr. Tyson calls for doubling the budget of NASA.  His passion for space exploration is based on science and on capitalism.  He really is brilliant as both a scientist and a populist.  If you can possible afford the time, please listen.
