ISS Science for Everyone

Science Objectives for Everyone
The Germination of ABI Voyager Barley Seeds in Microgravity project evaluates the effects of a microgravity environment on dry seeds, germination, and initial growth of Hordeum vulgare L. (barley). The dry barley seeds are evaluated during post-flight growth to examine exposure effects on seeds. The seedlings grown in microgravity are evaluated for genetic alterations and morphological abnormalities.

Experiment Description

Research Overview

  • Germination of ABI Voyager Barley Seeds in Microgravity evaluates the effects of microgravity exposure on dry seeds.
  • The germination and seedling phases of barley seeds that are grown in a microgravity environment are also evaluated.
  • Ten independent seedlings are grown within a set of two Seed Germination CubeLabs.
  • After the expected growth period, the growth material is fixed to allow for post-launch analysis.
  • Morphological and genetic effects of the environment are assessed during orbit and return.

Applications

Space Applications
Barley is a versatile grain equipped with antioxidants, vitamins and minerals essential to health. By furthering the knowledge of barley’s response to microgravity, investigators find ways to adapt the grain for long-duration spaceflight.

Earth Applications
Barley is an important grain used in a large variety of products, from bread to beer. By exposing barley to a space environment, morphological and genetic alterations may arise, broadening the knowledge of the grain and improving its use for terrestrial applications.

Operations

Operational Requirements and Protocols
The science is part of Payload Card-5 and it is contained into one 2U CubeLab for soft stow ascent (dry seeds) and two 2U CubeLabs for cold-stow ascent (germination). The dry seeds CubeLab remains in soft stow for the duration of the flight. The crew installs the germination CubeLabs onto a payload card and then into the TangoLab where autonomous operations occur. At the end of operations, the Crew removes, conditions and stows the hardware for cold stow return to Earth. The hardware is returned on the same vehicle and turned over to the Space Tango/Principal Investigator team upon early return.
