“We’re a rock with lights,” Captain Okonkwo said from the command deck, his voice tight. “Meteor swarm on trajectory 104. Intercept in four hours.”
On the command deck, the trajectory plot updated. The ship’s vector line bent away from the red swarm. It was working.
Mira looked around the engine bay. Her eyes landed on the emergency fuel cells—twelve lead-acid batteries, each a half-ton brick. They were useless without the engine. But they had mass. action reaction and momentum conservation
“Explain.”
She calculated the mass split: thirty tons ejected, twenty tons retained. The action: thirty tons at 500 m/s. The reaction: twenty tons at… she did the math. 750 m/s. Not much, but enough to shift their vector out of the meteor swarm’s path. “We’re a rock with lights,” Captain Okonkwo said
“We need a second push,” she said. “Conservation of momentum requires that the total momentum of an isolated system remains constant. We’re the system. We have to throw something else.”
She suited up and floated to the engine bay. Beside the seized rotor housing was the emergency spin-dump valve—a massive, explosive hatch designed to vent the rotor’s angular momentum into space as a last-ditch stabilization measure. The ship’s vector line bent away from the red swarm
“Yes, there is.”
