Aims:
Ground portion: The objective of this work is to demonstrate sustained crop production in a Veggie plant growth unit under ISS-like environmental conditions (23C, 50% RH, 3000ppm CO2; plant pillows) on the ground in an environmental growth chamber for a period of eight months. A multi-cropping approach consisting of multiple types of leafy greens per growth cycle will balance nutritional yield of target nutrients (Vitamins B1, C, K and potassium) and overall acceptability. Leafy greens chosen will be those down-selected from recent crop screening trials at KSC in addition to cultivars successfully grown on ISS. Two different harvest techniques, a traditional 30 day single harvest approach and a 60 day multiple harvest cut and come again approach will be utilized and contrasted in this project for a continuous period of four months each.
Validation of pick and eat system on ISS - protocols and resources for growing, maintaining, and harvesting safe, nutritious, and acceptable quality and variety of crops to supplement the prepackaged food system.

Description:
The deliverable will be a report that contributes to gap closure by validating requirements for a pick and eat system in flight. Implementation of these requirements is expected to support crew nutrition and psychosocial health on ISS and long duration missions
