How does the space station keep people alive?

The International Space Station (ISS) keeps people alive through a combination of life support systems that provide essential resources. It recycles air and water, removing carbon dioxide and purifying waste water to ensure a breathable atmosphere and safe drinking water. Additionally, it relies on solar panels for power, and the onboard systems regulate temperature and humidity to create a habitable environment. Regular resupply missions also bring food and other necessities to sustain the crew.
