Space Rocket History #24 – Mercury Redstone Test Flights – Ham in a Can

The objectives of the Mercury Project, were as follows:
1. Place a manned spacecraft in orbital flight around the earth.
2. Investigate man’s performance capabilities and his ability to function in the environment of space.
3. Recover the man and the spacecraft safely.
After the objectives were established for the project, a number of guidelines were created to insure that the most expedient and safest approach for attainment of the objectives was followed. The basic guidelines that were established are as follows:
1. Existing technology and off-the-shelf equipment should be used wherever practical.
2. The simplest and most reliable approach to system design would be followed.
3. An existing launch vehicle would be employed to place the spacecraft into orbit.
4. A progressive and logical test program would be conducted.

Space Rocket History #19 – Little Joe: Mercury’s Test Vehicle

“The designers made the Little Joe booster assembly to approximate the same performance that the Army’s Redstone booster would have with the capsule payload. But in addition to being flexible enough to perform a variety of missions, Little Joe could be made for about one-fifth the basic cost of the Redstone, would have much lower operating costs, and could be developed and delivered with much less time and effort. And, unlike the larger launch vehicles, Little Joe could be shot from the existing facilities at Wallops Island.”

Space Rocket History #17 – The Mercury 7

On April 1, 1959, Robert Gilruth, the head of the Space Task Group, Charles Donlan, Warren North, and Stanley White selected the first American astronauts. The “Mercury Seven” were Scott Carpenter, L. Gordon Cooper, Jr., John H. Glenn, Jr., Virgil I. “Gus” Grissom, Walter M. Schirra, Jr., Alan B. Shepard, Jr., and Donald K. “Deke” Slayton.

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.”
