Space Station Marking 20 Years of People Living in Orbit Associated Press CAPE CANAVERAL, FLA. - [1]The International Space Station was a cramped, humid, puny three rooms when the first crew moved in. Twenty years and 241 visitors later, the complex has a lookout tower, three toilets, six sleeping compartments and 12 rooms, depending on how you count. Monday marks two decades of a steady stream of people living there. Astronauts from 19 countries have floated through the space station hatches, including many repeat visitors who arrived on shuttles for short-term construction work, and several tourists who paid their own way. The first crew -- American Bill Shepherd and Russians Sergei Krikalev and Yuri Gidzenko -- blasted off from Kazakhstan on Oct. 31, 2000. Two days later, they swung open the space station doors, clasping their hands in unity. References 1. https://www.nasa.gov/ .
