Vegetable Production System (Veggie) - 07.29.14
ISS Science for Everyone
Science Objectives for Everyone
The Vegetable Production System (Veggie) is a deployable plant growth unit capable of producing salad-type crops to provide the crew with a palatable, nutritious, and safe source of fresh food and a tool to support relaxation and recreation. The Veggie provides lighting and nutrient delivery, but utilizes the cabin environment for temperature control and as a source of carbon dioxide to promote growth.

Previous ISS Missions
Biomass Production System (BPS), the precursor to Veggie, was utilized on ISS Expedtion 4.
With the long-duration missions aboard the International Space Station (ISS), it has become clear that more emphasis needs to be placed on improving human habitability. The Vegetable Production System (VEGGIE) provides a means to supply crews with a continuous source of fresh food and a tool for relaxation and recreation.
VEGGIE can support a variety of experiments used to determine how plants sense and respond to gravity. The plants will be harvested for further investigation and consumed by the crewmembers.
VEGGIE’s growth volume will be the largest volume available for plant growth on ISS. This will enable growth of larger plants that were previously not grown on ISS due to size restrictions. Additionally, the large, adjustable LED light bank makes VEGGIE an ideal facility for other experiments requiring a temporary light source.
As with all basic research, an improved understanding of plant growth and development has important implications for improving plant production on Earth.
VEGGIE is deployed in an EXpedite the PRocessing of Experiments to Space Station (EXPRESS) Rack.
The pillows with seeds in them are installed on to a root mat, which is installed into the VEGGIE bellows.
Power is applied and water is added to the root mat to begin seed germination. Water and growth height is maintained throughout the plant growth cycle until the vegetables are harvested and the growth cycle can be restarted.
