She hit the station’s emergency airlock at 23.1 kph, slammed the manual override, and tumbled inside as the outer door scraped her helmet.

PTC thermistors, embedded in the stator windings, measure the motor’s internal temperature. At nominal load, their resistance is low (typically < 750 ohms per sensor).

So she ran faster.

She thought of the equation her mentor had once written on a board: Heat = Mass × Specific Heat × ΔT . But also: Kinetic Energy = ½ mv² . Her body was the mass. Her speed, squared, was the only remaining source of warmth.
