• OGO 5 Spacecraft: OGO. Payload: OGO E. Mass: 634 kg.

  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.

• Canyon 1 Spacecraft: Canyon. Payload: Canyon 1 / Agena D. Mass: 700 kg.

  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.

• Canyon 2 Spacecraft: Canyon. Payload: Canyon 2 / Agena D. Mass: 700 kg.

• Rhyolite 1 Spacecraft: Rhyolite. Payload: AFP-720. Mass: 700 kg.

  First launch of Rhyolite geostationary ELINT satellite. Reportedly left in transfer orbit; other sources indicate a successful mission.

• Canyon 3 Spacecraft: Canyon. Payload: Canyon 3 / Agena D. Mass: 700 kg.

• Canyon 4 Spacecraft: Canyon. Payload: Canyon 4 / Agena D. Mass: 700 kg.

• Canyon 5 Spacecraft: Canyon. Payload: Canyon Improved. Mass: 700 kg.

  First launch of improved ELINT satellite. In comparison to earlier Canyon ELINT satellites, Improved Canyon had a similar but heavier payload which separated from the Agena D final stage.

• Rhyolite 2 Spacecraft: Rhyolite. Payload: AFP-720. Mass: 700 kg.

  Second launch of Rhyolite geostationary ELINT satellite.

• Canyon 6 Spacecraft: Canyon. Payload: Canyon Improved. Mass: 700 kg.

• Canyon 7 Spacecraft: Canyon. Payload: Canyon Improved. Mass: 700 kg.

• Rhyolite 3 Spacecraft: Rhyolite. Payload: OPS 4258. Mass: 700 kg.

  Third launch of Rhyolite geostationary ELINT satellite. Code name changed to Aquacade after Rhyolite name came out in trial of spy Boyce.

• Rhyolite 4 Spacecraft: Rhyolite. Payload: OPS 8790. Mass: 700 kg.

  Fourth and final launch of Rhyolite geostationary ELINT satellite. Code name changed to Aquacade after Rhyolite name came out in trial of spy Boyce.
