S. space exploration, Agena was an upper stage which was also employed as a spacecraft, the whole vehicle going into orbit. Agena played a key role in manned space flight; it was the target vehicle for rendezvous and docking maneuvers in NASA's Gemini project. Agena had a main rocket engine capable of multiple re-starts in space; in the modified target vehicle version it also had 2 secondary engines to provide small changes in velocity and position in orbit. In the Gemini Agena, a control system could handle 96 commands from the astronauts or from ground stations. Agena was used as an upper stage with the Thor, augmented Thor, Atlas and Titan boosters; it had played important roles in such military and NASA programs as Discoverer, Samos, Mariner, OGO, Lunar Orbiter, Ranger and Orbiting Astronomical Observatory.

• Titan IIIX space booster definition - .

  Space Systems Division began definition phase efforts for a new member of the Titan III family - the Titan IIIX space booster. The new vehicle would be two stages, Stage I with the man-rated components of the Titan Gemini Launch Vehicle and Stage II similar to that being used on the Titan III. The Titan IIIX would use radio rather then inertial guidance.

• Study of the Titan IIIX/Agena - . Martin Marietta Corporation of Denver, Colorado, initiated a study of the Titan IIIX/Agena system..

• Titan IIIB approved - .

  A memo from the Office of the Secretary of Defense to the Secretary of the Air Force, Eugene M. Zuckert, approved the Titan IIIX program and requisite lengthening of Titan III research and development. The Titan IIIX was essentially the Titan IIIA's first and second stages plus an adapter section that would allow the vehicle to be used with the Agena D upper stage.

• Titan III upgrades to be studied. - .

  Space Systems Division initiated Phase I studies with Martin Marietta Corporation, Thiokol, and United Technology Center (UTC) to determine what performance increment could be gained by strapping existing solid rocket motor segments to the Titan IIIX core vehicle. Minuteman first stages were to be considered along with two and three segments of the 120-inch diameter United Technology Center motors. The Titan IIIX/Strap-on configuration definition and acquisition phases were to be greatly compressed, with first launches from Vandenberg AFB expected in 1967. The Titan IIIX/Strap-on was subsequently designated Titan IIID.

• Titan IIIB/Agena D approved. - .

  A Headquarters USAF program management directive (PMD) approved the acquisition program for the Titan IIIX/Agena D (Program 624B), subsequently redesignated Titan IIIB/Agena D. This newest addition to the Titan III series of boosters would consist of the Titan IIIA first and second stages, an adapter section, and an Agena D third stage - everything up to the Agena interface being the Titan IIIX launch vehicle. Contracts were later awarded for 24 Titan IIIX vehicles, with first launch planned for the summer of 1966.
