The International Space Station (ISS) is a unique scientific platform where astronauts conduct experiments across multiple disciplines of research, including Earth and space science, biology, human physiology, physical sciences and technology DOWN TO EARTH demonstrations that could not be done anywhere else in the world. In 2020, the ISS Bringing scientific results CELEBRATING 20 YEARS celebrates 20 years of continuous human presence aboard the orbiting laboratory. back to Earth is an important role for the ISS.
