Battery performance is critical in space missions where resupply and repair are nearly impossible. To explore how microgravity affects battery efficiency and lifespan, Riverside Christian High School conducted an experiment aboard the ISS in collaboration with Valley Christian High and the Lowell Center for Space Science and Technology.
This experiment focused on common battery chemistries used in satellites and scientific payloads. Students investigated variables like discharge rate, voltage stability, and thermal behavior in zero-gravity conditions. On Earth, battery fluids settle due to gravity, which influences internal resistance and heat distribution. In space, these effects are altered, potentially changing the battery’s output and reliability.
Custom-designed enclosures housed the batteries along with sensors that tracked temperature, voltage, and cycle count over time. The aim was to compare these results with identical setups tested on Earth, highlighting differences caused by the microgravity environment.
The results contribute to broader efforts to optimize power systems for space travel. More efficient batteries mean longer missions, lighter spacecraft, and increased safety. This is especially important as humanity sets its sights on Moon bases, Mars journeys, and deep space probes.
Perhaps the most remarkable aspect of this experiment is its origin. It was imagined, built, and analyzed by high school students—proving that age is no barrier to contribution in space science. These students not only learned physics and engineering but also took part in a global conversation about sustainable exploration.
