Space Rocket History an Encore Presentation of Episode #27 – Mercury-Redstone 4 – Liberty Bell 7 with Gus Grissom

Mercury-Redstone 4 was the fourth mission in the Mercury-Redstone series and the second U.S. manned suborbital spaceflight. The mission was essentially a repeat of Alan Shepard’s Freedom 7 flight.   So why was it necessary to launch another sub-orbital mission?  Why not proceed with an orbital flight to match the Soviet Vostok 1?  Among other things the U.S. needed more space experience to corroborate the “Man-in-Space” concept.  Also the Redstone was the only booster NASA had that was approved for manned launches.  The Atlas booster was available but not ready.  Atlas was capable of putting a Mercury Capsule into orbit, but it had been launched three times with unmanned capsules, and it had exploded on 2 of the 3 attempts.

Space Rocket History #125 – Apollo: Astronaut Selection and Training – Part 3

“Some of those guys came in figuring, “I’ll write my textbooks and my thesis and teach [university courses] and I’ll come by twice a week and be an astronaut.” Well, that didn’t work …. We were devoting our lives to this whole thing, and you couldn’t devote anything less, I don’t care what your discipline was.”

Space Rocket History #124 – Apollo: Astronaut Selection and Training – Part 2

With Group 4, for the first time, the selection criteria did not include a requirement for test pilot proficiency. Selectees who were not qualified pilots would be assigned to the Air Force for a year of flight training. The primary scientific requirement was a doctorate in medicine, engineering, or one of the natural sciences.

Space Rocket History #123 – Apollo: Astronaut Selection and Training – Part 1

Selection of Group Two virtually depleted the pool of qualified candidates from the small corps of test pilots in the country, and it was the last group for which test-pilot certification would be a requirement. The new trainees reported to Houston in October 1962 to begin a two-year training course. A four-day work week was normally scheduled, the fifth day being reserved for public relations duties or for travel.
