Astronaut Janice E. Voss, payload commander, works at the Combustion Module (CM-1) experiment. Using a video monitor, Voss observes a flame during one the many burns in this facility that were conducted throughout the 16-day Microgravity Science Laboratory (MSL-1) mission. The combustion hardware is designed to sample and analyze gasses and soot on orbit and will be used to continue these studies onboard the International Space Station (ISS). Combustion is the single most important chemical process in every day life, in electricity, heat and automobiles, among other applications. This process is considered equally important in space and with the absence of gravity, the behavior of flames, soot, heat and gasses needs to be studied for beneficial uses as well as safety concerns in long-duration flights.
