NASA is canceling the Space Shuttle program for several reasons.

Firstly, there have been 2 space shuttle disasters, leaving 14 astronauts dead. Both accidents were caused by human error and severe problems with NASA management over the space shuttle program.

Secondly, the space shuttle is not a very safe vehicle. There have been many close calls on past shuttle missions that could easily have led to catastrophes. The space shuttle is still largely an experimental vehicle with new problems and safety issues being discovered.

Thirdly, there is no viable method for space shuttle crew members to escape in the event of an accident. Though Mercury, Gemini, and Apollo all had emergency escape systems, the space shuttle's crew escape system can only be used in a very small percent of circumstances, but in most emergencies the crew would have no chance of survival.

Lastly, the shuttle program is expensive. It costs an average of $450 million dollars and many months of training to prepare each shuttle launch.
