The last of the Titan rockets was launched on October 19th, 2005. This launch ends the Titan program, whose first launch was in 1959. Originally designed for carrying nuclear warheads, the Titan evolved into the workhorse rocket that could lift the heaviest payloads. The Titan was the launch vehicle for many well-known missions -
including manned Gemini missions, the Viking missions to Mars, the Voyager missions to the outer solar system, and the Cassini spacecraft now orbiting Saturn.
