Challenger was destroyed in a launch accident on January 28, 1986.
Columbia was destroyed during reentry on February 1, 2003.
The surviving four shuttles are Enterprise (flight tests), Discovery, Atlantis, and Endeavour (built to replace Challenger).

The Space Shuttles are old, expensive, and outdated. Two of the five US space shuttles were destroyed in accidents that killed all on board, which raised concerns about the safety of the spacecraft as well.
Space shuttles are placed in a hangar at Kennedy Space Center when not on a mission or on pre- or post flight processing. The very tall Vehicle Assembly Building is where they are prepared for flight and where the External Fuel Tank and Solid Rocket Boosters are joined to the orbiter. Post flight checks and repairs are also carried out here.

The Challenger and Columbia space shuttles were both destroyed in tragic incidents.

There are 3 now, Discovery, Endeavor, and Atlantis. Challenger was destroyed in 1986 and Columbia was destroyed in 2003.

3 G to allow crew to function in flight.
All major NASA space vehicle launches involving Manned Flight operations are executed at the Kennedy Space Center, Cape Canaveral, FLorida.
5 NASA Shuttles have been into space. Of those 5 shuttles, 2 were unfortunately destroyed. There has been a total of 135 Space missions using the space shuttle between the years 1980 and 2011 :)
There are currently no space shuttles in operation. The Space Shuttle program was retired in 2011 after the final mission of the Space Shuttle Atlantis. Some shuttles, such as Discovery and Endeavour, are on display at museums, while others, like Enterprise, were used for testing and were not space-faring shuttles.
Discovery, Atlantis and Endeavor have visited the ISS. Challenger (which was destroyed before the beginning of ISS construction) and Enterprise (which was a flight test vehicle and not space-worthy) have visited the International Space Station. Columbia was slated to visit the ISS on STS-118 but was destroyed on reentry and this mission was flown by Endeavour instead.
