Space Rocket History #71 – Agena vs. the Augmented Target Docking Adapter, with Some EVA Equipment on the Side

June 1, 2018 @ 10:29 am

Many doubted that Agena could be ready in time to meet Gemini’s tight launch schedules. The end of 1965 saw Agena’s usefulness in manned space flight once again called into question, but this time time a substitute target had already been approved for development…

Space Rocket History #69 – Zond 3, Venera 3, and Asterix

June 1, 2018 @ 10:05 am

The Zond program was one of two lunar exploration programs conducted by the Soviet Union to investigate the Moon and its vicinity. The program began in 1964 and ended in 1979. The early Zond’s 1-3 were originally designed for planetary exploration, while the latter Zonds (4-8) were sent on circum lunar flights. Additionally, the latter Zond vehicles were of a totally different in design. They were in fact automated versions of the manned Soyuz spacecraft…

Space Rocket History #68 – Gemini VI & VII with Wally Schirra, Tom Stafford, Frank Borman, and Jim Lovell – Rendezvous – Part 4

June 1, 2018 @ 9:53 am

The Gemini Program was conceived after it became evident to NASA officials that an intermediate step was required between Project Mercury and the Apollo Program. The major objectives assigned to Gemini were:
1-To subject two men and supporting equipment to long duration flights — a requirement for projected later trips to the moon or deeper space.
2-To effect rendezvous and docking with other orbiting vehicles, and to maneuver the docked vehicles in space, using the propulsion system of the target vehicle for such maneuvers.
3-To perfect methods of reentry and landing the spacecraft at a pre-selected land-landing point.
4-To gain additional information concerning the effects of weightlessness on crew members and to record the physiological reactions of crew members during long duration flights.

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

June 1, 2018 @ 9:40 am

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

June 1, 2018 @ 9:27 am

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.
