Brief Technical Description of the Particle Vibration (T-PAOLA) Experiment

The experiments have been carried out on board the ISS using the Selectable Optical Diagnostics Instrument, (SODI), an instrument for scientific research designed by QinetiQ Belgium (now Redwire) for the European Space Agency.  

Additional hardware, to host the specific fluid-particle mixtures required for the space experiment, has been manufactured and tested by QinetiQ UK.

Visit the Experiment Hardware Page fore additional technical information. 

SODI and the additional experiment-specific hardware have been installed inside the Microgravity Science Glovebox (MSG).
The Microgravity Science Glovebox (MSG) is a facility available on board the International Space Station. It can accommodate small and medium-sized experiments, which come from from many different disciplines. These disciplines include for example: biotechnology, combustion science, fluid physics, fundamental physics, It was developed by the European Space Agency (ESA) and is managed by NASA’s Marshall Space Flight Center and materials science.

The Microgravity Science Glovebox

The MSG can provide the experiment with power, data acquisition, computer communications, as well as specialized tools. 

Built-in gloves that attach directly to the door allow crew to safely manipulate samples inside the sealed facility. The MSG is generally used in combination with other specific experiment hardware, which is installed inside its Work Volume (WV). Side ports on the Glovebox enable the crew to set up and manipulate investigation equipment inside. The results that the ISS crew obtain can also be directly monitored by scientists and investigators on the ground. These capabilities make the MSG one of the most used facilities on the ISS.
