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

In 2003, NASA’s Marshall Space Flight Center tested a dual-pulse laser ignition system for rocket engines, revealing how microgravity alters ignition behavior. Insights from ground tests and microgravity experiments highlight the complexities of laser ignition, plasma formation, and flame propagation in reduced gravity environments.
