Agnirva Space Premier League - Expedition #32269: Magnetic Fluids in Orbit: Tracking Magnetorheological Changes in Microgravity

Imagine a liquid that stiffens when exposed to a magnetic field. That’s a magnetorheological (MR) fluid, and it’s a futuristic material with uses in shock absorbers, clutches, and even prosthetic limbs. Curious about how microgravity affects this material over time, students from Carmel Christian School in Matthews, North Carolina, designed an experiment aboard the ISS.

The project monitored how the magnetic responsiveness of MR fluids changes when free from Earth's gravitational forces. Without gravity-driven sedimentation, would the suspended magnetic particles behave differently? Could their magnetic alignment last longer or degrade in new ways?

This high-school-led investigation deepens our understanding of fluid mechanics in space, opening doors to space-based material manufacturing and fluidic systems. The educational impact is profound, equipping students with tools of experimentation and inspiring the next wave of space scientists and engineers.
