Two out of the five (six if you count Enterprise which never actually went into space). The two space shuttles destroyed were Columbia; on February 1, 2003, when shortly before it was scheduled to conclude its 28th mission, STS-107, the Space Shuttle Columbia disintegrated over Texas and Louisiana during re-entry into the Earth's atmosphere, resulting in the death of all seven crew members, and Challenger; Space Shuttle Challenger(mission STS-51-L) broke apart 73 seconds into its flight, leading to the deaths of its seven crew members. The spacecraft disintegrated over the Atlantic Ocean, off the coast of central Florida at 11:38 EST (16:38 UTC). Disintegration of the entire vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff.

No space shuttle has been launched for the moon. It can't carry enough fuel to get there. Couldn't land if it got there.

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.
It depends on the conditions of the space shuttle and how well it is maintained. Space shuttle discovery went on 39 missions to space
