Even NASA has to cut costs

The practice of business is partly all about cutting costs to maintain parity or gain profit. Unfortunately even NASA has to worry about options, cutting costs, and conscientious spending. NASA can't do whatever they want. On the space shuttle Atlantis scientists are trying to figure out which is the best way to fix all the dings and wholes in the fuel tank of the shuttle. Trying to fix the 2000+ dings that exist on the fuel tank might cause Atlantis to delay its scheduled departure time, but buying a whole new one is very spendy. So the question of costs versus profits arise.
