Martian Thermal Margin

Martian Thermal Margin is a space safety metric that tracks how much temperature headroom remains before a component exceeds limits for Mars relay, rover, and entry operations. 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 Martian Thermal Margin when the rover started a high-latency science pass, so the team could protect hardware during changing conditions before the next mission decision point.”
