Research Overview

  • NanoRacks-Girl Scouts of Hawai`i-Microgreen Plant Growth (NanoRacks-GSH-Microgreen Plant Growth) researches growing edible plants to support further space exploration by maintaining an available supply of fresh produce for said explorers.
  • NanoRacks-GSH-Microgreen Plant Growth grows arugula in a hydroponic system with 8 seeds, and c in a natural medium, and watered with .5 mL of tap water daily. Collect data on the plants’ germination and viability for harvest after only 11-15 days in a microgravity environment
  • NanoRacks-GSH-Microgreen Plant Growth provides 8 high school Girl Scouts from O`ahu, HI, a once in a lifetime learning and living experience through our Quest Institute partnership.
  • NanoRacks-GSH-Microgreen Plant Growth impacts the other 4,900 Girl Scouts of Hawaii, by showcasing the 8 team members and entire ISS project through our communications department.
  • NanoRacks-GSH-Microgreen Plant Growth impacts crewmember health directly through maintaining an available supply of fresh produce on lengthy missions in space.

Space Applications

NanoRacks-GSH-Microgreen Plant Growth shows how a simple plant and harvest system creates a readily available supply of fresh produce for consumption on lengthy missions or emergency situations in space.

Earth Applications

NanoRacks-GSH-Microgreen Plant Growth shows how, in a community with little to no agricultural land and sunlight, edible plants can be grown in a very small spaces and also be constantly viable and sustainable through artificial means at very low cost as well.

Operational Requirements

NanoRacks Module-22 is completely autonomous and only requires installation and removal. NanoRacks Module–22 returns on 33S.

Operational Protocols

Crew interaction with Module-22 is limited to transferring the NanoRacks locker Insert from the launch vehicle to the ISS, installation and activation of the NanoRacks Frames into the EXPRESS Rack Locker, cleaning of the air inlet filter (as necessary), and data retrieval (as needed) during the mission.
