One of the real workhorses of U. 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.

COSPAR: 1968-014A. Apogee: 111,034 km (68,993 mi). Perigee: 36,021 km (22,382 mi). Inclination: 50.3000 deg. Period: 3,746.50 min.

    OGO 5 carried 25 experiments, 17 of which were particle studies, and two were magnetic field studies. In addition, there was one each of the following types of experiments: radio astronomy, UV spectrum, Lyman-alpha, solar X ray, plasma waves, and electric field. By April 1971, spacecraft perigee had increased to 26,400 km and inclination had increased to 54 deg. The spacecraft attitude control failed on August 6, 1971, after 41 months of normal operation. The spacecraft was placed in a standby status on October 8, 1971. Four experiments (Meyer, Blamont, Thomas, and Simpson) were reactivated for the period from June 1 to July 13, 1972, after which all operational support terminated. Spacecraft orbit parameters changed significantly over the spacecraft life.

    The first "stretched" Atlas SLV-3A/ Agena D was launched from the Eastern Test Range. The "stretched" Atlas had an additional 117-inch tank section to provide more fuel, a longer burn time, and increased payload capability. First launch in a communications intelligence program operated by the USAF within the National Reconnaissance Office, on behalf of the National Security Agency. The first generation series, CANYON, was based on the Agena vehicle. The Agena D remained attached to the spacecraft. Positioned in geosynchronous orbit over the Indian Ocean. Last known longitude (30 December 1968) 98.50 deg W drifting at 0.166 deg E per day.
