Sergei reached into a Velcro-secured side pocket and extracted a small electric stun gun, capable of discharging a single twenty-thousand-volt shock, powerful enough to incapacitate an average man for thirty minutes. His people in Chechnya had managed to smuggle the tiny gun inside a Progress Russian cargo spaceship, which had arrived at the station just last week. Along with the gun came coded instructions from his Chechen contact in Moscow on the critical timing to take control of the station.
“Hey, Serg. You look pretty depressed today.” One of the American astronauts floated past him, patted Sergei on the back, and stopped in front of the food galley. The American was the current resident aboard the ISS from the United Nations Security Council. In addition to standard mission-specialist responsibilities, he was also chartered with the protection of the GPATS module. Ever since the UNSC deployed GPATS, a minimum of one crew member aboard the ISS possessed the training and the weapons to defend the military module.
Sergei didn’t respond, his eyes shifting from the American’s holstered stun gun to the back of his light blue flight overalls, identical to the ones Sergei wore, except that the muscular UNSC soldier filled his, while Sergei’s looked a size too big for his lanky frame.
The tall astronaut turned around, his hands fumbling with a brown pack of dehydrated peaches. His round face, pink and white, went well with his short hair. Curious brown eyes blinked at Sergei. “You okay, pal? You look sick. Have you been getting enough sleep?”
His heartbeat rocketing as he tried to hide the stun gun behind his back without looking suspicious. Sergei forced a smile, slightly closing his eyes as he nodded. “Yes, I am fine. Thank you.”
The bulky American shrugged, turning his attention back to his dried peaches.
Sergei Viktor Dudayev tightened the grip on the stun gun and gently pushed himself toward the food galley, arming the weapon and pressing its bare-wire ends against the soldier’s neck.
A light buzzing sound filled the Habitation Module as the pouch flew off, spilling its contents in a brownish cloud. The American jerked for a moment and went limp, his arms floating in front of his body.
First incapacitate, then kill.
Blocking out all emotions, Sergei choked his victim until breathing ceased. Then he felt for a pulse, finding none. Satisfied, he grabbed the dead man’s stun gun before pushing his body aside.
Adrenaline rocketing his heartbeat, Sergei stared toward the other end of the Habitation Module, where sleep compartments occupied both sides of the padded walls and the ceiling. A crewman slept in one of them. Another American, the station commander.
The Russian cosmonaut drifted toward him, coming to a rest in front of the compartment. The commander’s arms floated loosely to the sides as his head leaned slightly forward. The Velcro straps securing him against the padded board applied just enough pressure on his body to create the illusion of sleeping in a comfortable bed.
Sergei curled the hairy fingers of his right hand around the plastic case of the UNSC soldier’s stun gun, and without further thought, drove the hot end of the weapon into the side of the commander’s neck. The astronaut opened his eyes and stared at Sergei in surprise, before his eyes rolled to the back of his head and his arms jerked forward, almost as if trying to reach for his attacker. The motor reflex ended a moment later, and, again, Sergei strangled his incapacitated victim.
The Russian unzipped the front of the American’s suit and removed a key attached to a chain around his neck. The American also wore a small badge around his neck. Briefly eyeing the credit-card-size object, Sergei decided to come back to it later. Right then he needed both ISS master keys.
Sergei Dudayev floated to his first victim and retrieved a second key, before approaching the center of the module and eyeing the closedcircuit TV monitors of the operations workstation. There he verified that the remaining crew members, one British and one Japanese, were still inside the U.S. Laboratory Module, the forty-four-foot-long pressurized cylinder similar in shape and size to the Habitation Module. Satisfied, he inserted both keys on the top of the keyboard of the Multipurpose Application Console, linked to the electronic core of the ISS’s network. From here, Sergei had control of all onboard subsystems such as electrical power, thermal control, data management, communications, interface with ground control, and even full space station attitude control and orbit altitude.
Sergei Dudayev bypassed all manual overrides of the airrevitalization system and emergency hatch releases of the U.S. Laboratory Module. A few more strokes of the keys and he heard the alarms going off across the station as the computer system automatically isolated the laboratory from the rest of the station by closing and locking the hatches at both ends of the module.
His eyes drifted back to the flat-panel monitor, which now showed two astronauts frantically waving at the camera and reaching for the radio. Sergei turned the intercom system off. He didn’t care to hear their pleas, just as the world had refused to listen to the cry of his people as Russian forces raped his beloved Chechnya.
Visions of his explosive youth, of his slaughtered friends, of his hasty departure filled his mind as Sergei typed again. This time he overrode the air pressurization and revitalization control system of the station and began to bleed the air still trapped inside the Laboratory Module into space. The astronauts continued to wave and scream in front of the camera, but their struggle didn’t last long. Soon they began to breathe through their mouths. Their movements grew clumsier, erratic, until they went limp.
The Russian quietly followed the bodies floating in the monitor. His soul could hear their screams now, their shouts and pleas for mercy. All four astronauts had died without really knowing Sergei’s motive, without an explanation as to why their lives had to end so abruptly inside this man-made pocket of life traveling at thousands of miles per hour over a fragile Earth.
The two keys giving him access to all modules of the station, including GPATS, Sergei quickly typed the appropriate commands on the MPAC workstation, unlocking the latching mechanism that isolated GPATS from the rest of the station. Locking the MPAC system by removing both keys, Sergei used a single arm motion to propel his weightless body across the length of the Habitation Module, where a hatch connected that end of the module to Node One, also known as Unity, a pressurized cylinder fifteen feet in diameter and eighteen feet long sporting six hatches that served as docking ports for the other modules. A hatch connected to the U.S. Laboratory Module, another to the GPATS Module, and a third to the airlock, where the crew could suit up prior to EVAs, extravehicular activities, or space walks. The hatch immediately above Sergei led to a Russian-made Soyuz capsule to be used by the crew of the station to return to Earth in an emergency. Sergei planned to use the Soyuz Escape System (SES) to return to Earth after he had completed his mission.
A fifth hatch attached a cupola to Unity. Composed of eight large windows arranged in a circle over the node, the cupola provided the crew of the ISS with a 360-degree field of view in azimuth and complete hemispheric field of view in elevation of Earth. Part of the instrumentation aboard the cupola was the control system for the ISS robot arm, a larger and more versatile version of the venerable robot arm of the space-shuttle program. Unity’s sixth hatch was used to dock with visiting shuttles or Russian Progress supply ships. The other end of the U.S. Laboratory Module connected to Node Two, which led to additional modules on that side of the station, including the Columbus research module from Europe, and the Japanese experimental module.
Using the handholds built in along the padded walls lining Unity, Sergei directed himself into the GPATS Module. Placing his feet into the secure straps in front of the latched hatch, he applied nine pounds of pressure on the hatch actuator lock lever, turning it 180 degrees. The hatch opened to the contour of Unity’s inner wall. Sergei pulled it toward him about six inches, before pivoting it up and to the right side, exposing the crowded interior of the GPATS module.
Unlike the other modules, illuminated with so
ft white overheads, the interior of GPATS had a green glow designed to minimize eye fatigue during prolonged combat situations. Viewed from the inside, the module looked like a half cylinder. The side facing Earth was completely taken up by the BLU-85s, each stored in its own individual compartment and stacked ceiling high for the entire length of the module, leaving a three-foot-wide “walkway” between the wall of shelled warheads and the left side of the compartment. The forward section of the side of GPATS opposite the warheads consisted of two large computer consoles, each capable of launching warheads if the order ever came from the United Nations Security Council. The workstation closest to the hatch had a red light above it, meaning it was the system currently designated as active. The other system, set in standby mode, served as backup.
Farther down the left side Sergei saw the single computer system controlling the powerful GPATS laser, gimbal-mounted above the module. Gliding past gleaming instrumentation and displays, the Russian cosmonaut reached the laser system, whose operation he had had to learn before being qualified as mission specialist. ISS regulations dictated that every crew member aboard the ISS knew the operation of the laser in case of an emergency. The operation of the warheads, however, was limited to UNSC personnel, mostly American. In the event that a mission specialist like Sergei figured out how to operate the warhead-launching system, he would be incapable of doing so without the authorization codes, which were kept in a safe next to the workstation. Sergei had picked up bits and pieces of the launching procedure during a recent drill by eavesdropping on an intercom channel. If the order to launch ever came, the authorized crew would use their keys simultaneously to open the safe and extract the sealed envelopes containing the launch codes, which would then be compared with those received from Earth. If the codes matched, the order to launch one or more warheads would be executed. Such precautions were required given the fact that albeit nonnuclear, each warhead was capable of leveling downtown Washington, D.C. However, no authorization from the Pentagon or the United Nations was required to use the laser, particularly if there was a need to deflect or vaporize space junk in a collision course with the station. Its use in an emergency was at the sole discretion of the station commander.
Sitting behind the controls of the GPATS laser, Sergei activated the search-and-tracking radar, which, in conjunction with the tracking systems of three reflectors positioned in geosynchronous orbit 23,000 miles above the Earth, had the capability of detecting and tracking anything in orbit.
Sergei went to work, commanding the laser’s search-and-tracking system to scan the space along an east-to-west elliptical orbit of 274 kilometers in perigee and 150 kilometers in apogee with an inclination of 63.4 degrees—the orbit of Russia’s latest Cosmos surveillance satellite, currently Russia’s eyes over the border between Chechnya and Dagestan to the north. Sergei adjusted the system’s sensitivity to filter out objects smaller than ten feet in length. It took an additional minute before the search-and-tracking system came back with an object roughly the size of a school bus.
Sergei Viktor Dudayev smiled.
I see you.
His fingers moved almost automatically, selecting an energy setting, width of beam, and duration of event. Giving the controls one last inspection, he commanded the laser to fire.
The hydrogen-fluoride chemical laser gun, receiving its power from massive solar-rechargeable batteries, created a high-energy beam of light, which streaked across space to one of three reflective mirrors in geosynchronous orbit. The fifty-foot-diameter segmented mirror, actively cooled by a steady flow of liquid hydrogen running below its reflective surface, and whose angle had already been determined by its radio link with GPATS, deflected the beam with only a four percent loss in energy. The beam continued on its new trajectory, which abruptly ended when it came in contact with the laminated twenty-four-karat gold skin of the Cosmos orbital reconnaissance satellite.
Although the beam only remained in contact with the satellite for a few seconds, the laser’s energy changed into intense heat, slicing through the skin, evaporating the metal, and instantly frying the sophisticated electronics housed in its core.
Before manning the workstation controlling the warheads, Sergei used the keys to extract the launching codes from the safe next to the system. He activated the system and spent a few minutes typing the thirty-characters-long codes, working through several menus and levels of security. Another set of codes allowed him to move down the encrypted system until he reached the directory where the launching software resided. A few more keystrokes and the twenty-one-inch Sony color monitor displayed a list of warheads, labeled UNSC15KTSN001 through UNSC15KTSN030 in cyan on a black background.
He placed an index finger, trembling from excitement, over a springtensioned trackball—a mouse didn’t work well in zero gravity—bringing the cursor to the BLU-85 warhead SN#001. Sergei’s plan, which he had secretly worked out two weeks prior to his launch with Nikolai Naskalhov, an aide to the president of Chechnya, was simple: gain control of the warheads as a hammer against the Russian troops threatening to invade Chechnya. The destruction of the Russian satellite had been Sergei’s message to Moscow that the people of Chechnya now had an ally high above the clouds. As he gained control of GPATS, another message was being delivered to the Kremlin: unless the Russian 157th armored division retreated from the border with Chechnya, he would release a warhead over an undisclosed location. More demands would follow.
The adrenaline rush making it difficult to swallow, Sergei clicked the button beneath the trackball. He wanted to activate the warheads and have them ready for launch at a moment’s notice.
The UNSC15KTSN001 warhead turned magenta, and a message appeared:
UNSC15KTSN001 HAS BEEN SELECTED INSERT VALID UNSC ACCESS CARD TO ACTIVATE
******00:59******
A slot opened beneath the monitor and a red LED began to blink next to it.
Sergei froze.
Insert Valid United Nations Security Council access card?
Why would he need one when he had already logged into the system and entered all the authorization codes successfully?
Confused, Sergei glanced at the screen again. It now read:
UNSC15KTSN001 HAS BEEN SELECTED INSERT VALID UNSC ACCESS CARD TO ACTIVATE
******00:55*****
And a second later,
UNSC15KTSN001 HAS BEEN SELECTED INSERT VALID UNSC ACCESS CARD TO ACTIVATE
******00:54******
The Russian’s soft eyes widened in fear when he realized the system would not let him start the launch sequence unless he inserted a UNSC access card in the slot within the next fifty-four seconds. The UNSC had added a safety feature that he didn’t know existed, and if the system was as secured as he expected it to be, he would probably only get one chance at inserting the card before the computers would lock him out.
But where do I—
You idiot! The station commander! The card! He glanced at the screen once more.
UNSC15KTSN001 HAS BEEN SELECTED INSERT VALID UNSC ACCESS CARD TO ACTIVATE
******00:47******
Sergei jumped off the chair and propelled himself to the entrance of the GPATS module, floated across Unity, and into the Habitation Module. Shoving aside the American floating next to the galley, he reached the end of the long, cylindrical compartment, halting his momentum by holding on to the edge of the sleeping compartment.
He tugged at the chain around the neck of the dead station commander, but it didn’t give. Beads of sweat lifting off his forehead, the Russian raised the chain over his victim’s head. Holding the electronic card in his left hand, he kicked his legs against the side of the sleeping compartment, propelling himself back toward Unity. He miscalculated his zero-G flight, crashing his right shoulder against the edge of the passageway. The impact deflected his forward momentum, sending him floating out of control inside Unity.
Wasting precious seconds, ignoring the pain, Sergei clawed at anything within reach to regain control, grabbi
ng on to a built-in handle next to the hatch connecting Unity to the cupola. In the process, he let go of the card, which floated toward his feet.
In one swift motion, Sergei snagged the chain, pulling the card to his chest. Kicking his legs against the cupola’s control panel, he shot himself through the D-shaped entry of the GPATS module, reaching the workstation a moment later.
******PROCEDURE VIOLATION****** TIME LIMIT EXCEEDED. SYSTEM RESET IN PROGRESS
******167:59:54******
Procedure violation! He had missed the window by six seconds!
Sergei tried to insert the badge, but the slot was already closed. He tried to type a command to reset the system manually, but the system would not respond. The keyboard was locked. He tried the power switch on the side of the machine, but it did not have any effect. The system was obviously designed to bypass all exterior input after such violation, and it would remain like that for 168 hours—one week—before it would let him try again.
Sergei was familiar with procedure violations, and the only way to reset the system before the stated time was by entering a special access code known only by four people in the world: The U.S. President, the Russian President, the British Prime Minister, and the Secretary General of the United Nations. The procedure was implemented as a safety measure against exactly this type of intrusion. One week was usually enough time to get either a shuttle or a Russian Soyuz packed with armed United Nations forces up here. During his last six months of training at Johnson Space Center, in Houston, Sergei had seen a platoon of UN Security Forces in similar zero-G training exercises. While Sergei trained to use a screwdriver in space, the soldiers practice zero-G warfare tactics. But fortunately for Sergei, he still had a chance of pulling this off. It just would take a little more time and a hell of a lot more nerve.
Moving up the module to the laser station, Sergei quickly verified his access to the laser. Unlike the warheads, the laser system could never be locked—as long as the user had the right authorization codes. Otherwise, the station ran the risk of getting damaged by space junk. He moved over to the backup warhead-deployment workstation, next to the one he had locked.
