The International Space Station is a football-field-sized laboratory orbiting about 250 miles up, circling Earth every 90 minutes at 17,500 mph. Built and operated by the United States, Russia, Europe, Japan, and Canada, it has hosted people without interruption for over two decades, the longest continuous human presence off the planet.
Crews of about seven conduct thousands of experiments in microgravity, from growing organs-on-chips to studying how the human body handles long spaceflight. Astronauts rotate up on SpaceX Dragon and Soyuz spacecraft, with cargo arriving on commercial resupply flights.
Nearly everything NASA knows about keeping humans alive in space for months at a time was learned on the ISS. That knowledge is the foundation for Artemis lunar stays and eventual Mars trips. It is also where commercial spaceflight grew up: the companies now flying crews cut their teeth on station contracts.
