MVIS Controller-1 (MVIS Controller-1) - 05.06.15
The Microgravity Vibration Isolation System (MVIS), developed by the Canadian Space Agency, gives experiments a quieter ride in orbit. Equipment on the International Space Station (ISS) can jitter and shake as crew members go about their activities, as the station’s solar panels rotate, and as fans spin to move air. MVIS Controller-1 isolates experiments from these tiny vibrations, serving as a sort of noise-canceling headphones (vibrations in this case) for sensitive experiments. MVIS Controller-1 also investigates new control techniques that can isolate experiments from vibrations more efficiently. Science Results for Everyone

Previous ISS Missions
- To learn more about the vibration environment of the ISS and how to isolate experiments from it.
- Characterize the cables connecting MVIS Controller-1 to its rack and the environment in which it is located. Develop new control techniques to be able to isolate experiments from vibrations more efficiently.
- Better knowledge of vibration isolation techniques.
Fluid experiments in space are valuable because the earth's gravity influences their free behavior, but small vibrations can still negatively affect experimental results. Vibrations from normal crew and station's machine operations can act like very low gravity forces. Electromagnetic voice coils in MVIS counteracts these vibrations, isolating the experiments so researchers see the actual fluid behavior without interference.
Eliminating the micro-scale effects of gravity on fluid experiments helps researchers fine-tune a wide range of industrial processes on Earth. For instance, MVIS Controller-1 has supported an experiment that investigates gravity’s role in water evaporation on Earth, which can provide insight for the design of better cooling systems. Isolating fluid experiments from space station jitter provides a clearer understanding of basic physical forces.
