Insect Habitat
From Wikipedia, the free encyclopedia
The Insect Habitat was a science payload intended for the International Space Station as part of the Space Station Biological Research Program (SSBRP). The insect research element of the program was managed by the Canadian Space Agency, and the prime contractor for the Insect Habitat was Routes AstroEngineering, of Ottawa, Ontario.
The habitat would have housed six separate colonies of fruit flies. Each of these was divided into two compartments, separated by a rotating food cartridge. Fruit flies, which have a short life cycle, tend to lay their eggs in their food supply, to provide their offspring with a source of nourishment after hatching. After the eggs were laid, the food cartridge would be rotated, segregating the generations of flies so they could be studied separately. Multigenerartional studies were possible in this way, if each generation was removed from the colony before its offspring's eggs were ready to be segregated.
The Insect Habitat was unique among those in the SSBRP in that it contained its own centrifuge to simulate gravity for the flies, and did not require use of the full-size centrifuge to be provided on-station.
The project was put on hold when Space Shuttle flights were interrupted after the destruction of Orbiter Columbia in February 2003.
