The nematode worm Caenorhabditis elegans is a model organism for spaceflight biology, and they have been the stars of the latest voyage of the Soyuz spacecraft to the International Space Station. C. elegans is a common, well-studied organism used in biomedical research as a model for human development, genetics, aging and disease. The recent award of a Nobel Prize in Medicine to three pioneering worm researchers has demonstrated the value that has been placed on the worm as a model system by the scientific and medical communities.
