 An artist's concept of a Bion satellite in orbit | |
Bion (Russian:Бион), also namedBiocosmos,[1] is a series of Soviet and Russianbiosatellites focused onspace medicine.
The Soviet biosatellite program began in 1966 withKosmos 110, and resumed in 1973 withKosmos 605. Cooperation in space ventures between theSoviet Union and the United States was initiated in 1971, with the signing of the United States andSoviet Union in Science and Applications Agreement (which included an agreement on space research cooperation). The Soviet Union first offered to fly U.S. experiments on a Kosmos biosatellite in 1974, only a few years after the termination (in 1969) of theU.S. biosatellite program. The offer was realized in 1975 when the first joint U.S./Soviet research were carried out on theKosmos 782 mission.
The Bion spacecraft were based on theZenit spacecraft and launches began in 1973 with primary emphasis on the problems of radiation effects on human beings. Launches in the program includedKosmos 110,605,690,782, plus Nauka modules flown onZenit-2Mreconnaissance satellites. 90 kg (200 lb) of equipment could be contained in the external Nauka module.
The Soviet/Russian Bion program provided U.S. investigators a platform for launching Fundamental Space Biology and biomedical experiments into space. The Bion program, which began in 1966, included a series of missions that flew biological experiments using primates, rodents, insects, cells, and plants on a biosatellite innear Earth orbit.NASA became involved in the program in 1975 and participated in 9 of the 11 Bion missions.[2] NASA ended its participation in the program with theBion No.11 mission launched in December 1996. The collaboration resulted in the flight of more than 100 U.S. experiments, one-half of all U.S. life sciences flight experiments accomplished with non-human subjects.[2]
The missions ranged from five days (Bion 6) (Kosmos 1514) to around 22 days (Bion 1 and Kosmos 110).[3]
In 2005, the Bion program was resumed with three new satellites of the modified Bion-M type – the first flight was launched on 19 April 2013 fromBaikonur Cosmodrome,Kazakhstan. The first satellite of the new seriesBion-M1 featured an aquarium by theGerman Aerospace Center (DLR)[4] and carried 45mice, 18Mongolian gerbils, 15geckos,snails,fish andmicro-organisms into orbit for 30 days before re-entry and recovery.[5][6] All the gerbils died due to a hardware failure, but condition of the rest of the experiments, including all geckos, was satisfactory. Half the mice died as was predicted.[7]
Bion-M2 is scheduled to launch no earlier than March 2025 on aSoyuz 2.1a rocket to an altitude of 800 km.[8] The orbiter will carry 75 mice and studies will focus on how they are affected at the molecular level by space radiation.
