The mobile service tower, or gantry, at Space Launch Complex 40 on Cape Canaveral Air Force Station falls to the ground after the base was demolished. The tall lightning towers around it will remain. This mammoth structure, with its cavernous clean room, was used for the final spacecraft launch preparations for NASA’s Cassini spacecraft, currently orbiting Saturn. The launch occurred on Oct. 15, 1997, aboard an Air Force Titan IV-Centaur rocket. The facilities at the pad are being dismantled to make room for the construction of launch pad access and servicing facilities for the new Falcon rockets to be launched by Space Exploration Technologies, known as SpaceX.
