Next, Patrick turned his efforts to analyzing Mars One’s armament. Even what little was known left no doubt that the station had been designed and built for one purpose and one purpose only: to conduct sustained combat operations in space.
The two lasers Brad and Boomer had observed in action were plainly upgraded models of the Hobnail carbon-dioxide, electric-discharge weapons carried aboard Russia’s rocket-launched Elektron spaceplanes. Their lethality at relatively short ranges had been demonstrated by the speed with which they engaged and destroyed the Sky Masters recon nanosats. By correlating the known thermal resistance of the materials used to build the nanosats and the time it took the lasers to kill them, he was able to develop a reasonable estimate of their energy output. And that, in turn, enabled him to pin down the Russian lasers’ probable maximum effective range — which was somewhere between eighty-five and one hundred and twenty kilometers.
Patrick nodded to himself. The station’s lasers were primarily defensive weapons. Against targets moving at orbital speeds, battles fought at one hundred kilometers or less were practically knife fights.
Mars One’s offensive punch came from the plasma rail gun that had wrecked Brad and Boomer’s spaceplane. Close study of images showing the starfish-shaped array of supercapacitors around the weapon’s central tube confirmed Lawrence Dawson’s speculation that it was a MARAUDER-type plasma gun. Somehow, Patrick doubted that was simply a coincidence. Over the years, the West’s intelligence agencies had penetrated several of Russia’s most closely held weapons research and development programs. But espionage was a door that opened both ways. He strongly suspected a thorough probe of the long-sealed MARAUDER research files would find Russian digital fingerprints all over them.
Still immersed in the data stream, he resisted the temptation to slide off target and waste time scanning through the U.S. Air Force Research Laboratory’s computers to confirm his hunch. How the Russians originally got their hands on this technology was a question for another day and time. What mattered right now was that they’d turned it into a powerful and incredibly long-range weapon — one that had already destroyed most of America’s reconnaissance satellites. Current observations suggested it could hit and kill targets at well over four thousand miles.
Patrick shook his head in astonishment. The Russian scientists and engineers who’d built that damned rail gun had evidently figured out how to create plasma toroids that remained stable for close to a second in a vacuum, far beyond anything yet achieved in any Western lab. Their success was a damning indictment of the shortsighted politicians and defense officials who’d abandoned similar U.S. efforts decades ago.
With an inward sigh at the folly and carelessness his countrymen had exhibited, he moved on.
During the nanosat flyby of Mars One, Brad had identified several other camouflaged hatches and ports. Knowing how the Russians, especially Gryzlov, thought, Patrick had little doubt those masked more weapons systems — probably a mix of missiles and conventional autocannons, like the 23mm gun the Soviets had test-fired aboard their old Salyut-3 space station back in the 1970s. But conventional missiles and cannons, powerful though they might be individually, could not begin to match the firepower produced by the station’s plasma rail gun and its two shorter-range Hobnail lasers.
No, Patrick thought coldly, those directed-energy weapons were the chief threat posed by Mars One. Without them, the Russian station would be nothing more than an orbiting target — vulnerable to any number of missiles and lasers already in the U.S. and Sky Masters arsenals. With them, it circled the earth as a lethal, effectively impregnable fortress. Whatever Mars One’s sensors could see, its plasma rail gun could kill… and at unprecedented distances.
He shifted slightly in his chair. The energy required to power those weapons must be significant, around a hundred kilowatts for each of the lasers and considerably more for the plasma gun. Where was it coming from? Certainly not from the space station’s solar panels.
Images captured by ground-based telescopes and by the Sky Masters nanosatellites made it possible to calculate the size of those arrays. Even assuming the Russians had figured out how to increase their panel efficiency beyond the 30 to 40 percent range achieved by those aboard the old International Space Station, Mars One could not possibly generate more than one hundred kilowatts from solar power.
Patrick frowned. He’d read the reports from the Scion team in Russia. Alexei Rykov, the former cosmonaut candidate they’d tricked into spilling details about Gryzlov’s top secret program, had claimed Mars Project personnel were being trained to operate and maintain small, high-efficiency fusion power plants. Most analysts had dismissed this otherwise unconfirmed claim as dubious. They were skeptical that the Russians could have developed compact fusion technology ahead of the United States or other Western nations. And frankly, he’d shared that assessment…
But now?
Mars One had a working and deadly plasma rail gun — a weapon that was beyond the current technological reach of the United States and its allies. That much was undeniable. Was it safe to assume that was the only scientific and engineering breakthrough Moscow had achieved?
Hell no, Muck, Patrick told himself, using the nickname his friends had given him long ago. Fusion reactor or not, it was obvious that the Russian space station must have some kind of advanced power generator aboard. How else could its crew hope to fire their rail gun and lasers repeatedly in combat? No amount of battery storage could keep those weapons charged during a prolonged fight.
For a moment, he sat motionless, gripped by a sudden fear that the Russians had gained an insurmountable lead over the United States. In seeking a way to defeat Mars One, he might only be hunting a chimera, something that was impossible. How in Christ’s name could they hope to win a battle against this monstrosity? That space station’s plasma gun could kill any spacecraft or missile long before it closed within striking range. And with the power generated by a working fusion reactor, the Russians had the ability to fire the damned thing as rapidly as they could recharge its supercapacitors.
Or could they?
Patrick suddenly opened his eyes, thinking hard. Bring up all data collected during every observed attack on an American satellite and spacecraft, he ordered his computer through the neural link. He closed his eyes again in intense concentration. Reams of information spooled through his mind. The intelligence gathered from more than thirty separate engagements was intriguing. Mars One’s rail gun had killed targets over a wide variety of distances. Brad and Boomer’s S-19 had been nailed at point-blank range, at least in astronautical terms. But the station’s last kill, another Trumpeter ELINT satellite, had been fried at more than four thousand miles while on its way back up to apogee in an elliptical Molniya orbit. The intervals between Mars One’s attacks were equally varied — varying from as short as several minutes to as long as an hour or more.
Images of the Russian space station cascaded past his closed eyes. In every case, there was the same dazzling pulse as the plasma gun fired — a flare of white light so intense that it obscured even the bright glare of the sun reflected off Mars One’s solar arrays.
The sun…
Like a hunting dog suddenly catching a scent, Patrick leaned forward in his chair. The sun. That was the one constant amid all the variation. So far, Mars One had never fired its directed-energy weapons while the station itself was deep in Earth’s shadow. Which could mean—
