A thought-provoking and humorous collection on NASA and the future of space travel. Neil deGrasse Tyson is a rare breed of astrophysicist, one who can speak as easily and brilliantly with popular audiences as with professional scientists. Now that NASA has put human space flight effectively on hold with a five- or possibly ten-year delay until the next launch of astronauts from U.S. soil Tyson s views on the future of space travel and America s role in that future are especially timely and urgent.
