Brief Summary

The Microgravity Vibration Isolation System or MVIS was developed by the Canadian Space Agency to give fluid experiments a quiet ride in orbit. Even though everything seems to float smoothly in space, conditions are quite jittery at the microscopic level as astronauts exercise, solar panels rotate, and fans spin. MVIS acts like noise-canceling headphones to reduce micro-vibrations to an acceptable level for fluid experiments.

Experiment Description

Research Overview

  • To learn more about the vibration environment of the ISS and how to isolate experiments from it.


  • Characterize the cables connecting MVIS 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.

Applications

Space Applications

Microgravity fluid experiments study how materials behave at the molecular level without gravity disrupting or dominating other effects. But vibrations from normal operations and crew movements aboard ISS become the equivalent of very low gravity forces. Electromagnetic voice coils in MVIS counteracts these vibrations so researchers see just the fundamental fluid behavior.

Earth Applications

Eliminating gravity's effects from fluids experiments on ISS will help fine-tune a range of industrial processes on Earth. For example, MVIS has supported an experiment that investigates the role of gravity in how water evaporates and should help in the design of better cooling systems for use on Earth. This is the third generation of vibration isolation MVIS flight hardware since Canada started this research in 1996.
