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 and utilizes the cabin environment for temperature control and as a source of carbon dioxide to promote growth. Veggie is also used for fundamental space biology experiments such as the series Advanced Plant Experiments (APEX) and educational space biology activities.

    Facility Description

    Facility Overview

    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. A portion of the crop plants are typically harvested and consumed by the crew members with the remaining harvest packaged and returned to Earth for further analysis.
     
    Veggie's growth volume is one of the largest volume available for plant growth on ISS. This enables 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.

    Operations

    Facility Operations

    • Veggie is deployed in an EXpedite the PRocessing of Experiments to Space Station (EXPRESS) Rack. Crop plants can be grown in pillows and PONDS units.
    • Plant pillows with seeds in them are installed onto a root mat, which are installed into the Veggie bellows. Water is injected into the pillows and mat.
    • Power is applied and light levels set. Water and growth height is maintained throughout the plant growth cycle until the vegetables are harvested and the growth cycle is restarted.
    •  The handheld light meter and sensor will enable a better assessment of the light environment for plants. Some plants are sensitive to light during the night cycle and understanding Photosynthetically Active Radiation (PAR) intensity from external sources through Veggie’s clear bellows can be important for crops such as the tomato plant. The light meter is portable, battery operated, handheld, and can be used with various sensors. On-orbit with the light meter is a quantum light sensor which measures the number of photons ranging from 400nm to 700nm also known as PAR. PAR units are μmol/m2 s.
