Google Maps in collaboration with NASA is enabling people around the world to take a trip to the doorway to outer space. This location is our largest special collection of Street View imagery to date, totaling 6,000 panoramic views of the facilities, and expanding our mission to document the world’s most amazing places.Among the images you can now explore online with the click of your mouse are the space shuttle launch pad, Vehicle Assembly Building and Launch Firing Room #4. Gaze down from the top of the enormous launch pad, peer up at the towering ceiling of the Vehicle Assembly Building (taller than the Statue of Liberty) and get up close to one of the space shuttle’s main engines, which is powerful enough to generate 400,000 lbs of thrust. From these vantage points, anyone can live out his or her childhood dream of becoming an astronaut.
