Project HotSat Mission 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
