She had exactly four hours until the colony’s oxygen scrubbers went into cascading failure.

Elara wiped the sweat from her brow with the back of her glove. Inside the radiation-hardened bunker, the air was cool, but the pressure was suffocating. Outside, the sky above the Martian colony was a sickly copper color—a sign that the atmospheric processor Vallis-4 was failing. She had exactly four hours until the colony’s

Elara’s fingers flew across the keyboard of her debugger. She had salvaged this G4 from a decommissioned rover’s motor drive. It was tough, rated for -40°C to 125°C, and packed with 512KB of Flash. Elara wiped the sweat from her brow with

Elara leaned back, her heart pounding. She looked at the STM32G474, now glowing softly with an activity LED she had tacked onto PA5. It was running at 170 MHz, its core temperature barely above ambient.

For a terrifying second, nothing happened. The oscilloscope showed a flat line.

The old controller for the Vallis-4 had been fried by a coronal mass ejection. The backup was a generic ARM chip, too slow to handle the precise pulse-width modulation needed to drive the magnetic bearings of the main turbine. Without nanosecond-accurate timing, the turbine would shake itself apart.
