What Science Happens on the ISS?

The microgravity environment enables research impossible on Earth. Protein crystallization experiments have produced crystals far superior to terrestrial ones, accelerating drug development. Fluid physics research has revealed behaviors impossible to observe under gravity. The station monitors Earths climate, tracking hurricanes, deforestation, and volcanic eruptions from above. Astronauts study their own bodies to understand how prolonged weightlessness affects bone density, muscle mass, vision, and the immune system. This research is essential for planning Mars missions. The station also tests technologies for deep space travel, from life support systems to radiation shielding. Over 3,000 investigations have been conducted from researchers in over 100 countries. The ISS is not just a space station; it is a laboratory that cannot exist anywhere else.
