20 years in orbit

The International Space Station is marking its 20th anniversary circling Earth, completing 16 orbits of the planet each day. Construction began on Nov. 20, 1998, but perhaps the station’s most remarkable achievements came in November 2000, when the first human crew arrived: a US Navy Seal and two Russian cosmonauts. As such, the space station is not only a technological achievement but also a remarkable example of international cooperation.
