The mobile service tower, or gantry, at Space Launch Complex 40, was imploded on Sunday, April 27, 2008. This mammoth structure, with its cavernous clean room, was used for the final spacecraft launch preparations for NASA's Cassini spacecraft, currently orbiting Saturn. This historic launch occurred on Oct. 15, 1997, aboard an Air Force Titan IV-Centaur rocket. The existing facilities at the pad are being dismantled to make room for construction of new launch pad access and servicing facilities for the new Falcon rockets to be launched by SpaceX.
