Advanced Plant Habitat
<ul><li>The Advanced Plant Habitat (APH) is a fully automated plant growth facility that will be used to conduct plant bioscience research on the International Space Station. The system requires minimal crew involvement to install the science, add water, and for other maintenance activities.</li>
<li>The system was developed by NASA and ORBITEC of Madison, Wisconsin. The system’s components are managed by and processed for flight at the agency’s Kennedy Space Center in Florida.</li>
<li>The APH is a fully enclosed, closed-loop system with an environmentally controlled growth chamber. The plant habitat uses red, blue and green LED lights, and broad spectrum white LED lights. The system contains more than 180 sensors, relaying real-time information, including temperature, oxygen content and moisture levels (in the air and soil, near the plant roots, and at the stem and leaf level), back to the team at Kennedy.</li></ul>
