Agnirva Space Premier League - Expedition #32287: Three Space Tech Breakthroughs, One Student Mission: Heat Transfer, Radiation Detection, and Light Propulsion

In one of the most ambitious student-led missions aboard the ISS, Valley Christian High School researchers combined three separate investigations into a single payload. Each component explored a vital area of space technology: heat dissipation using ferrofluid, radiation detection with a solid-state Geiger counter, and light-induced propulsion via a graphene sponge.

First, the ferrofluid experiment explored how magnetic fluid could be used to manage heat in zero gravity. On Earth, heat rises and disperses through convection, but in space, heat can become trapped. Ferrofluids, which respond to magnetic fields, could offer a way to direct and transfer heat efficiently. Students used magnetically controlled ferrofluid to see if it could carry heat away from electronics.

Second, the Geiger counter test verified whether solid-state radiation sensors could function reliably in microgravity. With space radiation posing significant risks to astronauts and equipment, confirming that these compact, energy-efficient counters work in orbit is crucial.

Third, the graphene sponge experiment investigated a futuristic concept—light propulsion. When hit by a laser or high-energy light, the sponge was expected to move slightly, suggesting potential for ultra-light spacecraft propulsion mechanisms.

Each component revealed valuable insights. The ferrofluid flowed differently in space, highlighting challenges and potential in thermal control. The Geiger counter performed as expected, confirming its utility. The graphene sponge showed measurable motion under light, supporting theories about photon-driven propulsion.

This tri-experiment mission demonstrates how student innovation can address high-stakes challenges in aerospace engineering, physics, and sustainability.
