The Space Shuttle Endeavour, stacked with its two SRB's and external fuel tank. Endeavour (OV-105) was the fifth and final operation shuttle built. It was constructed out of the various spare parts and structural spares of the prior four shuttles. The way this pin depicts Endeavour is how it will be displayed at the California Science Center in Los Angeles, California. Endeavour flew 25 missions, clocking a total of 7,179 hours of flight. Some of Endeavours highlights (though all of its missions are hightlights!) include the first Hubble Space Telescope service mission, the ISS assembly mission 2A where node 1, Unity Module, was taken to space which was the first American component of the space station. It also delivered the Cupola to the space station!
