Exploring Chemical Hand Warmers for High-Altitude Satellite Applications

This project investigates the viability of chemical hand warmers for use in high-altitude conditions, specifically at 30 km where oxygen levels are low, and pressure is high. By analyzing their functionality, we aim to determine if these warmers can provide enough heat to sustain electrical instruments on small satellites, potentially enabling students and hobbyists without Multi-Layer Insulation (MLI) to launch their own payloads. Our team, comprised of various engineers and researchers, is focused on designing an oxygen sensor and optimizing hand warmer deployment prior to launch.

  2. Project HotSatMission Overview • Examine how chemical hand warmers function when exposed to low levels of oxygen and high pressures • Whether or not a chemical hand warmer still functions at 30 km • If chemical hand warmers can produce enough heat to allow the electrical instruments to continue to function, they might allow students and hobbyists who do not have access to MLI the ability to launch their own small satellite 1Lynn, Maggie. “How Hand Warmers Work.” Live Strong.
