Testing life for long-distance spaceflight


NASA scientists are studying how genetics affects the suitability of plants for long-haul space travel.

At NASA's Kennedy Space Center, organisms in a Petri plate are exposed to blue excitation lighting in a Spectrum prototype unit. Scientists and engineers working on the Spectrum project are developing new hardware for the International Space Station, to support experiments demonstrating how different organisms, such as plants, microbes or worms, develop under conditions of microgravity.

Results from the Spectrum project will shed light on which living things are best suited for long-duration flights into deep space. What make this system unique is it will allow scientists to observe how different genes are turned on and off while the organisms grow in space. The Spectrum experiments are important because genes control the physical and functional similarity between generations of plants. However, genes do not determine the structure of an organism alone. Environmental factors such as lighting and microgravity are other influences that can determine what types of plants are best suited for long spaceflights.
