The space shuttle program cost American taxpayers $93 each year.
(Over the years the United States has spent $196 billion on the space shuttle program over its lifespan. The total cost of the program over its life was supposed to be $90 billion for up to 50 launches per year. The highest number of shuttle launches in any one year was only nine.
With the retirement of the shuttles, the space station will now rely on Russian, European and Japanese rockets to bring up supplies, and now, without its own shuttle program, NASA will have to spend $64 million per astronaut per trip to hitch a ride on a Russian spacecraft.)
