Now, Mija! Joe thought. He took one last nauseating breath of the methane-filled air and fought harder to keep his head up.

The structural technician AIC triggered the software per Buckley's orders and a string of valves were released in order to allow the flow of the DEG liquid metal coolant to flow through the damaged heat-pipe conduit. The extreme pressures in the flow loop didn't take long to overcome the weakened metal in the pipe. Mija released the structural integrity field around the pipe at that location and the eight-hundred-degree-Celsius liquid sodium- potassium alloy flowed out of the pipe in a high-velocity jet with nearly explosive force. A small rupture in the pipe vented the liquid metal like a rocket nozzle that passed through both of Buckley's legs, cutting them off instantly and cauterizing them almost as quickly.

The heat pipe forced more and more of the liquid metals into the raw sewage that at the same time was converted quickly to steam. The heavy-liquid metals began to settle into the bottom of the pool of sewage and were forming dense methane gas clouds just above the surface of the brown sludge. Buckley had had a good idea from a mechanical and industrial flow point of view what would happen, but his lack of chemistry knowledge was going to be his undoing.

The chemical reaction of sodium and potassium metal and water created sodium hydroxide, potassium hydroxide, heat—which was already in abundance—and hydrogen gas, which was highly explosive and had a very low flashpoint to boot. Plus there was a cloud of methane vapor rapidly forming just below the cloud of hydrogen rapidly percolating to the top of the room. The natural buoyancy of the two gases forced the heavy methane to pool on the surface of the sludge and the lighter hydrogen to pool at the top of the room. The sewage continued to drain into the compartment and was just as rapidly vaporized by the influx of molten liquid sodium-potassium alloy that was now covering the deck of the engineering room and beginning to eat away at the deck coverings.

Fireman's Apprentice James King had held on firmly to the aft bulkhead, as Hull Technician Joe Buckley had ordered him to do. The sight of the young sailor was one of the last things Joe would ever see as he struggled to keep his head above the surface. As if the searing pain from his amputated legs, the noxious gas fumes that were burning at his lungs, and the sodium and potassium hydroxide eating away at his skin weren't enough, finally the heat from the searing liquid metal exploded out of another failing part of the conduit, spraying his face with a mist of the molten vapors, melting his face and eyes to beyond flesh all the way to the bone.

Mija . . .

Rest, Joe. I'm here.

Did it work . . . ?

Rest, Joe. I'm here. Mija uploaded the control code to Uncle Timmy with priority status since she knew that she would not last long enough to execute the final commands of the flow system that Buckley had engineered. The AIC had figured out the chemistry a little too late herself to warn her counterpart, but in time that they wouldn't die in vain.

Finally the hydrogen gas cloud reached critical density for the heat in the room, the heat from the liquid metal, and the exothermic reaction. The overpressured clouds of gases and lack of oxygen had kept the room from igniting initially, but the heat of reaction and molten metal had finally reached the flashpoint for the volatile mixture. It ignited with explosive force. In turn, the compressed hydrogen gas cloud explosion ignited the methane fog with the force of several tons of explosives that blew a hole forty meters in diameter and out the three decks below and into space and upward six decks, killing hundreds of unsuspecting sailors. The explosion did blow out the fires created by the failing heat flow systems in the engineering decks but in the process it covered hundreds of sailors with septic human waste products on several decks. Several members of the crew were lost from explosive decompression and others just simply suffocated before they could make it to oxygen bottles. The remains of the sewage and the liquid metal quickly vented into the vacuum of space. The remains of Hull Technician Petty Officer Third Class Joe Buckley and Fireman's Apprentice James King would never be found.

Chapter 20

2:01 Mars Tharsis Standard Time

'Prepare to fire the gluonium-tipped torpedoes, XO,' Captain Jefferson ordered the suicide command. There was no way that the Madira could survive a close-range teraton explosion. But the Separatist hauler was on a collision course for the Tharsis Mons region of the planet below and that would kill millions. Maybe as many as ten or twenty million. It had to be done.

'Aye sir!' the XO said begrudgingly. At almost the same instant the ship vibrated with a myriad of notes that sounded almost like a bosun's pipe combined with the jarring of the tracks on a garbage conveyor. The ship lurched forward and that was followed by a secondary explosion. Warning klaxons sounded throughout the ship for fire and damage control teams.

'Shit!' The helmsman was thrown face-first into his control console, busting his forehead open. Bright red blood streamed down his face, getting into his eyes, and he frantically rubbed at it trying to regain his composure and right the attitude of the ship.

Uncle Timmy detected the explosion only milliseconds after the upload from Mija and realized what was happening. Mija Kitty's last effort was to upload the instructions to the flagship's AIC on how to bring the main guns online. Timmy quickly flushed the DEG flow systems with dry air and then ran the water reservoir and forward sewage into the pipes while shunting off the bleeding end of the flow loop on the aft and below decks of the ship where the explosion had just occurred. What was left of the molten liquid metal coolants flowed out into the vacuum of space where the below deck aft engineering room had been. Timmy also made record of the heroic activities of her counterpart's last moment of life that the AIC had uploaded. If they survived this situation Petty Officer Third Class Joe Buckley would posthumously be promoted to petty officer second class and Fireman's Apprentice James King would become a fireman. Of course, the Madira would have to survive first.

'What the hell just hit us?' the CO exclaimed.

'Goddamnit!' The COB's coffee cup was jarred loose from his hand and cracked on the deck. 'That ain't a good sign.'

'I don't know, CO, but the forward DEGs are coming online!' the XO replied with extreme enthusiasm. 'I've got several targeting solutions on the kamikaze.'

'Take out its propulsion and attitude control first. Then go for its structural integrity,' Captain Jefferson ordered.
