Space Rocket History #147 – Saturn: S-II Stage Part 2: Trials and Tribulations

“The S-II stage was a nightmare the minute it was conceived, and it only got worse from there. During the course of its creation, it would grind up people and careers the way the transcontinental railway devoured laborers.  Though the methods and materials used to build the S-II were reasonably well known, nobody had ever tried to apply them on such a titanic scale.  Originally, it was to be somewhere around 8 stores tall with a diameter of 22 feet, but the width ballooned from there to 27 feet before the contract was  even signed, then to 30, and finally to 33 feet.  And all the while as the size of thing increased, NASA was trimming the allowable weight.”  Harrison Storms of NAA.

Space Rocket History #67 – Gemini VI & VII with Wally Schirra, Tom Stafford, Frank Borman, and Jim Lovell – Rendezvous – Part 3

From the previous episode, we have Gemini VII waiting in orbit for Gemini VI-A to launch and rendezvous.  Remember, Gemini VII could only remain in orbit for 14 days, the maximum duration of its flight.  The goal was to launch Gemini VI-A on or before day 9 of Gemini VII’s mission.

Space Rocket History #66 – Gemini VI & VII with Wally Schirra, Tom Stafford, Frank Borman, and Jim Lovell – Rendezvous – Part 2

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.
