Agnirva Space Premier League - Expedition #32671: Turning Humidity into Drinkable Water: ISS Water Capture Device

Water is one of the most critical resources aboard the International Space Station. The Water Capture Device, tested during Expeditions 61/62 and 65, was designed to improve how astronauts recycle and purify water.

Led by Scott Hansen at NASA’s Johnson Space Center, this technology demonstration aimed to capture humidity and condensation from the air and convert it into clean, drinkable water. This process is especially important for long-duration missions where resupply from Earth is limited.

The device mimics natural processes like condensation and filtration but adapts them for the unique environment of space. By improving water recovery rates and reducing the need for external resupply, it contributes to making life in space more sustainable.

It also provides a valuable testbed for future lunar and Martian habitats where in-situ water generation will be vital. This experiment demonstrates NASA's commitment to developing closed-loop life support systems for human spaceflight.
