Space Rocket History #145 – Surveyors 2 – 7 with a Little Apollo 12

The primary objectives of the Surveyor program, were to support the Apollo landings by: (1) developing and validating the technology for landing softly on the Moon; (2) providing data on the compatibility of the Apollo design with conditions encountered on the lunar surface; and (3) adding to the scientific knowledge of the Moon.

Space Rocket History #117 – Apollo: Lunar Module Design

Since the lunar module would fly only in space (earth orbit and lunar vicinity), the designers could ignore the aerodynamic streamlining demanded by earth’s atmosphere and build the first true manned spacecraft, designed solely for operating in the spatial vacuum.

Space Rocket History #86 – Gemini XII With Jim Lovell and and Edwin (Buzz) Aldrin – Part 1

When the  Gemini IX-A Agena fell into the Atlantic Ocean, Gemini XII was threatened with a major hardware shortage of an Agena and an Atlas to launch it. Replacing the Agena was no real problem. Lockheed’s first production model, 5001, used for development testing at the Cape, had already been sent back to the Sunnyvale plant for refurbishment. Now it was simply a matter of tailoring it to the Gemini XII mission…

Space Rocket History #85 – Gemini XI With Charles (Pete) Conrad and Richard Gordon – Part 3

The rotation rate checked out at 55 degrees per minute, and the crew could now test for a minute amount of artificial gravity. When they put a camera against the instrument panel and then let it go, it moved in a straight line to the rear of the cockpit and parallel to the direction of the tether. The crew, themselves, did not sense any physiological effect of gravity.
