One second after 11 o’clock Wednesday morning, April 8th 1964, the Titan II booster’s first-stage engine ignited. Four seconds later, the 156 ton vehicle lifted from the pad on that curiously lambent flame so distinctive of Titan II’s hypergolic propellants. Within moments, Gemini-Titan 1 vanished into the hot Florida sky, beyond reach of human senses but not electronic sensors. Telemetry data flowed back to mission controllers at the Cape, telling them that the launch was as nearly perfect as it looked.
“The primary objective of the first Gemini mission, was to prove that the Titan II was capable of launching the Gemini spacecraft into orbit within the tolerances imposed by manned space flight. The secondary objective was for the spacecraft to gather and report data.”
