Science Objectives for Everyone

Providing water for crewmembers is expensive due to the weight of the water upon lift-off.  NanoRacks-Henry Bauerschlag Elementary School –Antibacterial Products (NanoRacks-HBES-Antibacterial Products) seeks to successfully rid crewmember urine of harmful bacteria so it can be recycled as usable water and multiply the supply already on board.

    Experiment Description

    Research Overview

    • The cost of lifting-off the amount of potable water for a crew of six is expensive due to the weight of the water.

    • By chemically treating crewmember urine in order to keep bacteria from growing, the potable water that results can be re-used thereby multiplying the water supply on board.

    • Treatment removes the danger of disease while providing a water supply.

    Description

    The goal of the Bauerschlag Elementary team with the NanoRacks-Henry Bauerschlag Elementary School –Antibacterial Products (NanoRacks-HBES-Antibacterial Products) experiment is to provide scientifically valuable experiments while inspiring students at an elementary age group.  The students participating in this study are enrolled in the school district’s Gifted and Talented program and have demonstrated exceptional skill and interest in curriculum outside of the typical educational programs.  The experiment chosen is the use of anti-bacterial pretreatment of urine to demonstrate a simple method of minimizing bacterial growth in urine waste collection prior to water treatment used in human space flight for water recycling.  This activity also provided insight on real world issues to these young students, collaborating with various industry leaders, and developing an experiment that demonstrates measureable scientific results.  Working with Umpqua Research Company, the Bauerschlag team was able to receive state of the art pretreatment material, simulated urine, and samples of inoculated Escherichia coli (E. coli) bacteria.  The students created two sets of experiments. The first set included two mixture MixStix of 7 parts simulated urine and 2 parts of suspended E. coli with and without pretreatment.  The second set included two MixStix with pretreatment.  The first set was activated on Day One to allow the students to see the effects of the E. coli exposed to the simulated urine.  Within a week, the untreated urine became opaque while the treated urine remained transparent.  The second set of MixStix sent one MixStix with pretreatment to the International Space Station (ISS) with the other two MixStixs remaining on Earth.  When the MixStix on the ISS is activated, the two MixStix on Earth are activated.  The MixStix on Earth help us understand if there are any storage effects to the E. coli to ensure that the experiment conducted eliminates other variables and demonstrates whether the pretreatment worked as intended in a microgravity environment.

    Applications

    Space Applications

    Whether on the International Space Station, the Moon, Mars, or an asteroid, water is important and expensive to carry.  This chemical treatment extends the life of the potable water available and reduces the chance of disease.

    Earth Applications

    Water is becoming a sensitive issue on earth.  Emerging nations are especially affected by lack of a safe and sustainable water supply.  For the short-term, providing a chemical treatment for urine would be less expensive than building water treatment plants.  Backpackers, scientists in remote areas such as Antarctica, and, possibly, eventually, even homeowners or those caught in the infrastructure collapse in the aftermath of a hurricane or tornado could also benefit.

    Operations

    Operational Requirements

    Activation of all four MixStix occurs upon arrival to the ISS. Microscope inspection of all four MixStix occurs two to three days after activation. The Module returns on the next possible flight.

    Operational Protocols

    NanoRacks Module-9 S/N 1009 consists of 4 MixStix which are transported at ambient temperature and soft-stowed.  The crew stows the module inside NanoRacks Platform-1 once it arrives to the ISS.  The crew de-stows and activates the MixStix as required.  The crew utilizes the NanoRacks Microscope-2 to analyze the MixStix as needed.  The MixStix are stowed in Module-9 inside NanoRacks Platform-1 until they are de-stowed for return to earth.
