At 8:50 on the morning of November 3, 1966, a Titan III C missile lifted off from launch complex 40 at Cape Canaveral. It carried a spacecraft, the refurbished Gemini 2 spacecraft now called Gemini B, and a simulated laboratory module made form a Titan II stage one oxidizer tank. Gemini B followed it’s planned suborbital trajectory, splashing down 39 minutes after launch near Ascension Island in the South Atlantic. The Titan’s upper transtage, meanwhile, sent the simulated lab and its satellite payload into a nearly circular orbit roughly 191 miles above the Earth. The lab’s orbit quickly decayed, and on January 9, 1967, the only mission of the U.S. Air Force’s Manned Orbiting Laboratory space station program ended with its last vestiges burning up in the Earth’s atmosphere.
