In 2003, NASA Marshall tested a dual-pulse laser ignition system for rocket engines; a separate microgravity study examined laser ignition and flame spread in solid fuel

NASA engineers have successfully tested an innovative dual-pulse laser ignition system designed for rocket engines. This groundbreaking system divides laser energy into two separate pulses, enhancing the interaction with plasma. In another experiment focused on microgravity conditions, researchers observed the ignition of solid fuels, noting how reduced buoyancy influenced the movement of heat and combustion products near the ignition site.
