Space Station, a giant research facility orbiting the Earth,
is perhaps the most complex construction project in history. Sixteen
countries are building the station, including the United States,
Canada, Japan, Russia, Brazil, and eleven European nations. While
the station wont be complete until 2006, researchers around
the world already use its unique facilities for developing space-travel
technology, observing environmental processes on earth, investigating
human diseases, and much more. Hear Exploratorium staff interview
ISS astronauts about life on the ISS.
The space station is fueling a boom in the amount of time people
spend in space. This increase has prompted scientists to step up
research on the potentially adverse effects of extended space habitation.
One critical area of this research is an investigation of the high
levels of radiation in space and their potentially adverse impacts
on humans. (Above image is based on an artist's conception-NASA
