The photo today is a montage of the entire fleet of Gemini Titan II’s launched during the Gemini program.  On this day in 1962, NASA selected Titan II as the launch vehicle for the Mercury-Mark program, which became the Gemini program.  This montage has been used earlier this year for a previous event but is worth repeating.   

My current series in the MARS STAR is about the Gemini program.
