    Operational Requirements

    Module-1 is a device to grow the protein monocrystals. Module-3 is a device to grow bidimensional oriented films using the artificial epitaxy effect.

    Operational Protocols

    Test techniques in microgravity conditions to produce monocrystals of biological macromolecules and orient film-forming crystallites. Test the hardware, modes and conditions to grow the protein monocrystals and biological films. Estimate efficiency and reliability of the used hardware. Test the experiment timeline to organize the small-batch growing of biocrystals and films in microgravity conditions.

    Results/More Information

    Biocrystallization modules with the experiment results transported safely back to Earth for analysis, along with a log sheet with data of the experiment timeline. Also, the daily telemetry information of the air temperature in the accommodation area of biocrystallizers must be sent.
