The bright outlook that was prevalent in April turned dark in the late summer of 1964 when a series of natural disasters struck the Cape. First lightning, then hurricanes, damaged the Gemini 2 launch vehicle to delay its flight long past the schedule...

One second after 11 o’clock Wednesday morning, April 8th 1964, the Titan II booster’s first-stage engine ignited. Four seconds later, the 156 ton vehicle lifted from the pad on that curiously lambent flame so distinctive of Titan II’s hypergolic prop...

“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 gathe...

“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...

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 s...

“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...

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?
