Agnirva Space Premier League - Expedition #32691: Growing Roots in Zero-G: Exploring Plant Life with the XROOTS System

The eXposed Root On-Orbit Test System (XROOTS) is a revolutionary step forward in space farming. Instead of using soil or traditional hydroponics, XROOTS tests how plants grow using hydroponic and aeroponic systems—no dirt needed. It’s part of a larger vision for sustainable food production in space.

During Expeditions 66 through 69, this NASA-backed experiment deployed plant growth modules that expose roots to nutrients via air or mist, rather than being buried. The aim? To see how plant roots orient themselves, absorb nutrients, and support plant life in microgravity conditions.

This research is crucial for long-term missions where resupplying food is impossible. If astronauts can grow fresh produce onboard, it improves nutrition, morale, and mission sustainability. The XROOTS system also helps scientists learn how to build self-sufficient ecosystems beyond Earth.

It also provides exciting STEM learning opportunities. Students can see real-time video and data from plants growing in space, tying biology, engineering, and sustainability together. It’s space botany at its best—and a glimpse at the farms of the future.
