UDMHIRFNAThe Atlas Agena was an American expendable launch system derived from the SM 6. Atlas missile. It was a member of the Atlas family of rockets, and was launched 1. It was used to launch the first five Mariner unmanned probes to the planets Venus and Mars, and the Ranger and Lunar Orbiter unmanned probes to the Moon. The upper stage was also used as an unmanned orbital target vehicle for the Gemini manned spacecraft to practice rendezvous and docking. However, the launch vehicle family was originally developed for the Air Force and most of its launches were classified Do. D payloads. The Atlas Agena was a two and a half stage rocket, with a stage and a half Atlas missile as the first stage, and an RM 8. Agena second stage. Initially, Atlas D missiles, redesignated as the LV 3, were used as the first stage. These were later replaced by the standardized Atlas SLV 3, and its derivatives, the SLV 3. A and B. The final Atlas Agena launch used an Atlas EF. The earliest Agena variant was the Agena A in 1. Most of these were flown on Thor Agena boosters for the Discoverer program and only four used Atlases Midas 1, Midas 2, Samos 1, and Samos 2, two of which failed. Late in 1. 96. 0, Lockheed introduced the uprated Agena B stage which was restartable and had longer propellant tanks for more burn time. It first flew on the Thor and did not make its maiden voyage on an Atlas for months, when Midas 3 launched on July 1. Atlas Agenas were then used for Do. D and NASA programs, but proved a reliability nightmare as one failure after another happened. In late 1. 96. 2, after Ranger 5 suffered another booster malfunction albeit a minor one that ground controllers were able to work around, NASA convened a review board which undertook a wholesale reevaluation of the Atlas Agena as a launch vehicle. The board found that quality control and checkout procedures were poor, and that this situation was exacerbated by the several dozen configurations of the booster, as each individual Do. D and NASA program necessitated custom modifications to the Atlas and Agena, and the latter also differed in its Atlas and Thor variants. The board recommended improved quality control, better hardware, and also establishing one standardized launch vehicle for all space programs. The end result was the Atlas SLV 3 and Agena D, standardized versions of the Atlas D core and Agena B which would be the same on every launch at least as far as the Atlas was concerned, Agena Ds often still had customized setups, especially for Do. D payloads. The Agena D first flew in July 1. Do. D launches, but NASA continued using Agena Bs for the remaining Ranger missions. The Atlas SLV 3 meanwhile first flew in August 1. Dozens of Atlas SLV 3Agena D boosters were flown over the following years, mostly for the KH 7 Gambit program, also for a few NASA missions. The last Atlas Agena was flown in 1. SEASAT, but on a repurposed Atlas F missile rather than the SLV 3. Launches were conducted from Launch Complexes 1. Cape Canaveral Air Force Station, and Launch Complexes 1 and 2 at Point Arguello now SLC 3 and 4 at Vandenberg Air Force Base. VariantseditName. First launch. Last launch. Launches. Successes.

Destruct systemeditAll Atlas Agena vehicles contained an Inadvertent Separation Destruct System to destroy the Agena in the event that it separated prematurely from the Atlas, a situation that could be caused by a booster hard over or if the Atlas self destructed in flight. The ISDS charges were mounted on the adapter section between the two vehicles and would activate if a series of tripwires were broken. During the coasting period between staging, the ISDS charges were disabled. The Atlass own RSO charges were also wired so that they would destroy both vehicles if activated. Most Agenas also had their own separate RSO charges, although NASA planetary probes omitted them for weight saving reasons and due to the flight trajectory used, which meant that destruct of the Agena was no longer possible following staging. Two Atlas Agena flights involved an intentional destruct of the Atlas Mariner 1 and Canyon 4 while two others Midas 6 and Midas 8 resulted in an ISDS destruction of the Agena following in flight malfunction and self destruct of the Atlas. The Gemini Agena Target Vehicle had a specially modified Range Safety destruct system designed to fire slugs into the propellant tanks rather than the conventional method of rupturing them externally, since an inadvertent activation of the RSO system in orbit could endanger the Gemini astronauts. The very first Atlas Agena flight, Midas 1 in February 1. ISDS system mistakenly activated at staging, rupturing the Atlass LOX tank and causing the breakup of the Agena. The ISDS system was redesigned afterwards and this failure mode did not repeat itself. Production launchesedit. Ranger block I spacecraft bus was used for the first two Rangers, and also for the first two Mariner interplanetary probes. The Ranger spacecraft were designed to impact the Moon, returning photographs of the lunar surface until their destruction. The spacecraft was designed in three Blocks, all similar in appearance with a forward antenna and magnetometer, supported by a boom, with more sensors and two solar panels and a dish antenna mounted at the base. The first two Block I spacecraft, Ranger 1 and Ranger 2, were launched on August 2. November 1. 8, 1. Moon, but in intended high Earth orbits to test the Atlas Agena and spacecraft capabilities. However, the Agena malfunctioned on both flights and left the probes trapped in a useless low Earth orbit from which they soon decayed.
