The positive benefits of space exploration are innumerable and profound. As Joan Vernikos describes, '43 countries now have their own observing or communications satellites in Earth orbit.' Such satellites provide the G.P.S that directs our transport, meteorological forecasts, global monitoring of the environment, as well as surveillance and intelligence for our national security1. Furthermore, the common misconception that NASA has a huge budget is just that; in 2007, the NASA budget of $16.3 billion was dwarfed by the overall G.D.P of $13 trillion1. 1 Dubner, S. J.
