Family: orbital launch vehicle. Country: USA. Engines: AJ10-118E, AJ10-118G, MB-3-3. Spacecraft: Biosatellite. Launch Sites: Cape Canaveral, Cape Canaveral LC17B, Cape Canaveral LC17A. Stages: Delta Thor TA, Delta E, Castor 1. Agency: Douglas.

1966 December 14 - . 19:20 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC17A. LV Family: Thor. Launch Vehicle: Thor Delta G.
  • Biosatellite 1 - . Payload: Biosat 1. Mass: 425 kg (936 lb). Nation: USA. Agency: NASA Ames. Class: Biology. Type: Biology satellite. Spacecraft: Biosatellite. Decay Date: 1967-02-15 . USAF Sat Cat: 2631 . COSPAR: 1966-114C. Apogee: 309 km (192 mi). Perigee: 295 km (183 mi). Inclination: 33.5000 deg. Period: 90.40 min.

    Reentry into the Earth's atmosphere was not achieved because the retrorocket failed to ignite. The biosatellite was never recovered. Although the scientific objectives of the mission were not accomplished, the Biosatellite I experience provided technical confidence in the program because of excellent performance in most other areas.


1967 September 7 - . 22:04 GMT - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC17B. LV Family: Thor. Launch Vehicle: Thor Delta G.
  • Biosatellite 2 - . Payload: Biosat 2. Mass: 507 kg (1,117 lb). Nation: USA. Agency: NASA Ames. Class: Biology. Type: Biology satellite. Spacecraft: Biosatellite. Decay Date: 1967-09-15 . USAF Sat Cat: 2935 . COSPAR: 1967-083A. Apogee: 318 km (197 mi). Perigee: 297 km (184 mi). Inclination: 33.5000 deg. Period: 90.70 min.

    Biological capsule recovered. The scientific payload, consisting of 13 select biology and radiation experiments, was exposed to microgravity during 45 hours of Earth-orbital flight. Experimental biology packages on the spacecraft contained a variety of specimens, including insects, frog eggs, microorganisms and plants. The planned three-day mission was recalled early because of the threat of a tropical storm in the recovery area, and because of a communication problem between the spacecraft and the tracking systems. The primary objective of the Biosatellite II mission was to determine if organisms were more, or less, sensitive to ionizing radiation in microgravity than on Earth. To study this question, an artificial source of radiation was supplied to a group of experiments mounted in the forward part of the spacecraft.
