From the previous episode, it was decided that the name of Gemini VI would be changed to Gemini VI-a to distinguish it from the originally planned mission whose objective was to rendezvous with the Agena target vehicle. Gemini VII would be launched first before Gemini VI-a and it would be considered the target vehicle effectively replacing the Agena. After Gemini VII lifted off, Gemini VI-a would be transferred to the launch pad and prepared to launch as soon as possible. After Gemini VI-a rendezvoused with Gemini VII, it would return to earth before Gemini VII.

This was Flight Director Chris Kraft’s first major problem at the new Mission Control Center in Houston. He knew the spacecraft had enough battery power for reentry even if the fuel cells failed completely, but he needed to know if there would be time enough to reach a good reentry zone, such as the mid-Pacific near Hawaii on the sixth orbit…
The success of Gus Grissom and John Young’s Gemini 3 flight paved the way for long duration space missions. The longest U.S. manned space flight to date was Gordon Cooper’s 34 hour Mercury flight. The Soviets, however, had four long duration flights to their credit, ranging from 70 to 119 hours. It was time for the US to attempt a long duration flight.
