Space Rocket History #51 – Gemini 1 – Test Flight – Part 1

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.”

Space Rocket History #50 – Blue Gemini – 1963

“Blue Gemini” was the tag name for an Air Force manned space flight program to develop rendezvous, docking, and transfer for military purposes, using Gemini-type spacecraft. The concept became firmer in June, when the Air Force Space Systems Division (SSD) began working on plans to use Gemini hardware as the first step in a new Air Force man-in-space program called Mods (Manned Orbital Development System), a kind of military space station with Gemini spacecraft as ferry vehicles…

Space Rocket History #49 – Gemini Systems Design – 1962

On January 3 1962, “Gemini” became the official designation of the Mercury Mark II program. The name had been suggested by Alex  Nagy of NASA Headquarters because the twin stars Castor and Pollux in constellation Gemini (the Twins) seemed to him to symbolize the program’s two-man crew, its rendezvous mission, and its relation to Mercury. Coincidentally, the astronomical symbol (II) for Gemini, the third constellation of the zodiac, corresponded neatly to the Mark II designation…

Space Rocket History #48 – Gemini Design – 1961

“The main trouble with the Mercury capsule was that most system components were in the pilot’s cabin; and often, to pack them in this very confined space, they had to be stacked like a layer cake and components of one system had to be scattered about the craft to use all available space. This arrangement generated a maze of interconnecting wires, tubing, and mechanical linkages. To replace one malfunctioning system, other systems had to be disturbed; and then, after the trouble had been corrected, the systems that had been disturbed as well as the malfunctioning system had to be checked out again.”  James Chamberlin

Space Rocket History #47 – Gemini Concepts

This brings us to Project Gemini.  Gemini started after Apollo had begun, in part to answer a crucial question for Apollo. Was rendezvous and docking in orbit a feasible basis for a manned lunar landing mission?

Space Rocket History #44 – Voskhod-1with Kamarov, Yegorov, and Feoktistov – Part 1

Premiere Khrushchev was not willing to wait until Soyuz for another space first.  Khrushchev believed, There could be no final victories in the race for space propaganda.  He knew the US was working on project Gemini which would carry two astronauts in 1965.  So, as a means to upstage the US, Khrushchev ordered Chief Designer Korolev to fit three cosmonauts into the Voskhod spacecraft that was designed for two…

Space Rocket History #16 – Astronaut Candidates

Candidates were given continuous psychiatric interviews throughout the week, and extensive self-examination through a battery of 13 psychological tests for personality and motivation, and another dozen different tests on intellectual functions and special aptitudes–these were all part of the Week of Truth at Dayton.

Two of the more interesting personality and motivation studies seemed like parlor games at first, until it became evident how profound an exercise in Socratic introspection was implied by conscientious answers to the test questions “Who am I?” and “Whom would you assign to the mission if you could not go yourself?” In the first case, by requiring the subject to write down 20 definitional identifications of himself, ranked in order of significance, and interpreted protectively, the psychologists elicited information on identity and perception of social roles. In the peer ratings, each candidate was asked which of the other members of the group of five accompanying him through this phase of the program he liked best, which one he would like to accompany him on a two-man mission, and whom he would substitute for himself. Candidates who had proceeded this far in the selection process all agreed with one who complained, “Nothing is sacred any more.”
