Tittel

Water management in Space – monitoring of plant water status in small and closed environments

Sammendrag

The movement of water in, across and out of the plant is a key factor when growing plants as part of a closed regenerative life support system required for long duration space missions. Under microgravity conditions, it has been proved that transpiration rate of leaves is suppressed by retarding the water vapour transfer due to restricted free air convection. Previous experiments on the International Space Station (ISS) have illustrated the importance of monitoring the water status of plants in space. A frequently reported cause for loss of seedlings due to wilting is technical issues with hardware. This could possibly have been detected earlier and prevented if a better tool for monitoring the water status of the plants were available. Currently, experiments in existing growth facilities on the ISS, as well as new hardware, are being designed to assess and monitor plant water uptake and transport in microgravity. However, finding suitable methods for monitoring plant water status in space facilities have proven to be challenging. These challenges are induced by the confined environment, the limited amount of available water, as well as restrictions on upload mass and crew time on the ISS. Examples of hydration systems for plants on ISS, technologies used for monitoring the water status in the growth media in previous experiments, as well as future prospects will be presented.
