ISS Science for Everyone

Science Objectives for Everyone
NanoRacks-Dickinson High School-Space Cheeseballs (NanoRacks-DHS-Cheeseballs) tests the cheese fermenting process in orbit, to determine if food making processes work in microgravity.  Studying food making processes on the International Space Station (ISS) opens up new possibilities for future astronaut diet alternatives during long-duration missions beyond low Earth orbit (LEO).

    Experiment Description

    Research Overview

    • NanoRacks-Dickinson High School-Space Cheeseballs (NanoRacks-DHS-Cheeseballs) demonstrates the basic cheese making process on orbit.
    • NanoRacks-DHS-Cheeseballs illustrates food structures created in microgravity as opposed to being created on the ground and shipped up to space.
    • Exploring new food making processes in space, allows for fresh options in the astronaut diet.


    NanoRacks-Dickinson High School-Space Cheeseballs (NanoRacks-DHS-Cheeseballs) examines the process of making cheese in microgravity.  Buttermilk is combined with Rennet and the resulting fermentation reaction is observed. Rennet contains many enzymes that coagulate the milk, causing it to separate into solids (curds) and liquid (whey).  Observing this process in microgravity may lead to the development of dietary options for astronauts on future long-duration spaceflights.

    Space Applications

    NanoRacks-DHS-Cheeseballs provides insight into cheese fermentation and other food generation processes in microgravity that may be used on long-duration missions.

    Earth Applications

    Studying food making processes in space may lead to better processes here on Earth.

    Operational Requirements

    Activation of all four tubes occurs upon arrival to the ISS. Microscope inspection of all four tubes 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.
