Propulsion Thermal Margin

Propulsion Thermal Margin is a space safety metric that tracks how much temperature headroom remains before a component exceeds limits for thruster, burn, and maneuver systems. It uses sensor data, heat models, and operational constraints so teams can protect hardware during changing conditions while keeping evidence, reliability, and public-safe operational boundaries clear.

“The mission team used Propulsion Thermal Margin when the burn plan changed, so the team could protect hardware during changing conditions before the next mission decision point.”
