iss064e049484 (3/31/2021) --- A view of the Plant Water Management 3 and 4 investigation aboard the International space Station (ISS). The Plant Water Management 3 and 4 investigation demonstrates passive measures for controlling fluid delivery and uptake in plant growth systems. Reduced gravity creates challenges in providing adequate fluid and nutrition for plant growth. This investigation examines using other physical properties such as surface tension, wetting and system geometry to replace the role of gravity.
