ISS Science for Everyone

Science Objectives for Everyone
Brewer’s yeast (Saccharomyces cerevisiae) is used to make wine, beer and bread, and is an important model eukaryotic organism in biology. NanoRacks-Ben Shemen Youth Village High School-Yeast Breathing Activity (NanoRacks-BSYVHS-Yeast Activity) tests the behavior and growth capability of dry brewer’s yeast in microgravity. Results improve understanding of yeast life cycles in harsh environments, which benefits future exploration to the moon, Mars, asteroids or other destinations.

Experiment Description

Research Overview

  • NanoRacks-Ben Shemen Youth Village High School-Yeast Breathing Activity (NanoRacks-BSYVHS-Yeast Activity) is needed to better evaluate behavior of Saccharomyces cerevisiae (dry baker's yeast) under harsh (in this case microgravity) conditions.
  • The goal of the investigation is to better understand the characteristics and ability of yeast to grow in microgravity.
  • NanoRacks-BSYVHS-Yeast Activity applications include use of this Yeast organism in the research of ageing, gene and microbiology, deep space flight, brewing and other research.

Description
NanoRacks-Ben Shemen Youth Village High School-Yeast Breathing Activity (NanoRacks-BSYVHS-Yeast Activity) evaluates the behavior of Saccharomyces cerevisiae (dry baker's yeast) under harsh microgravity conditions. This microorganism is used in many research areas on Earth such as genome sequencing, interplanet space trave and survival, astrobiology, and ageing. The space flight on Fobus-Grunt failed, but studying this yeast in microgravity and determining the behavior and ability of the organism to withstand extreme conditions helps the research of all the above topics.

Applications

Space Applications
In 2011, the Planetary Society developed a payload for the Phobos-Grunt probe, which attempted to return a sample from Phobos, the larger of Mars’ two moons. The investigation aimed to study whether microorganisms can survive in interplanetary space, but the Phobos-Grunt spacecraft failed to leave Earth orbit and was destroyed. NanoRacks-BSYVHS-Yeast Activity conducts a similar investigation, providing new insight into different organisms’ ability to adapt to the harsh environment of space.

Earth Applications
Brewer’s yeast is used in a wide range of biomedical research on Earth, with implications for aging, genetics, and other fields. It is also used to produce food and beverages. Understanding how microgravity affects yeast provides new insight into the biology of this important organism. In addition, the investigation was designed by high school students, who held a competition to select a winning investigation. The students learned about the space environment and International Space Station (ISS) operations, connecting them to the space program and preparing them for future careers.

Operations

Operational Requirements and Protocols
The MixStix are unclamped to combine different compartments, typically causing either activation or deactivation of the experiment. The MixStix are returned to the students.
A crew member removes the Velcro tabs to open the Module-9 Ext lid. The crew member unclamps the fasteners on the MixStix as directed, enabling the materials in the various chambers to flow. The crew member then shakes the MixStix (when directed) to mix the liquids thoroughly. Repeat for all MixStix. Crew member notes the time of MixStix activation and replaces the tubes back in Module-9. The lid is replaced and secured with the Velcro tabs.
