Space Rocket History #101 – Apollo: Preliminary Design Part 2 – Mode, Command Module, and Astronavigation.

In May 1961, NASA was not really prepared to direct an enormous Apollo program designed to fly its spacecraft to the moon. New and special facilities would be needed and the aerospace industry would have to be marshaled to develop vehicles not easily adapted to production lines, but at this point no one had even decided just what Apollo’s component parts should be or how they should look.

Space Rocket History #100 – Apollo: Preliminary Design

In January 1960, President Eisenhower directed NASA Administrator Glennan to accelerate the Super Booster Program that had recently been assigned to NASA. This order ensured the transfer of the von Braun group from the Army Ballistic Missile Agency to NASA, and it gave Glennan the launch vehicle development and management capability that he needed.

Space Rocket History #98 – Apollo Beginnings

President Kennedy proposed the manned lunar landing as the focus of the US space program but, at the time of his address, only one American, Alan B. Shepard, Jr. had been into space, on a suborbital lob shot lasting 15 minutes. No rocket launch vehicle was available for a lunar voyage and there was no agreed upon method for placing any kind of spacecraft safely on the lunar surface and getting it back to the earth. Nor was there agreement within NASA itself on how it should be done.

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?
