"Does that worry you?"
"It does, frankly. You don't have to be a shrink to realize that someone who stays by herself so much may be having trouble coping. Problems like that get exaggerated in space. Up here we're all our brother's keeper…"
Ann took a sip of coffee (actually "sipping" with a straw-like drink tube on the cup was very difficult) and squinted as the liquid stung her throat. "I'm sure you're right but I don't think I'm a candidate for special treatment—"
"Anyone hassling you, bothering you in any way?" he persisted. "I know being the only female on the station can be a little awkward—"
"You know what it's like?" She smiled when she said it. "Well, I'm guessing it's a little like being the only general officer on this station."
He didn't return the smile. The lady seemed pretty damn defensive… "I can't exactly be 'one of the boys' around here, but I can't afford to alienate anyone, either. I walk a tightrope, which I imagine you have to do, too… Look, I'm just trying to help. Sorry if I'm out of line." He watched her for a moment. "You don't much like it up here, do you?"
"What I like doesn't matter. I also don't want any special treatment, okay, General? I have a job to do — and that's what matters…"
An awkward silence, then: "You're really very attractive, you know…"
She just looked at him, started to say something, then set down her coffee cup on the Velcro counter. "General, if you really knew what it's like to be the only female on this station, you wouldn't have just said that." She pushed off the floor, floated past him out through the galley hatch.
He watched her receding form, shook his head. Way to go, Jason. You really can be an ass.
"Attention on the station, two minutes… mark. Report by station when secure for test."
Ann took one last sip of water from the squeeze bottle, then stuck it on a Velcro strip on the ceiling. On earth she might have squirted the rest of the water down her shirt to help battle the heat and perspiration, but in space such a luxury was impossible. The Skybolt control module was oppressively warm, stifling; the equipment air conditioning and cooling fans may have been keeping her instruments comfortable, but the module's lone occupant felt as though she was in a sauna.
She sat at her tiny control station completely surrounded by equipment. The only illumination came from the twelve-inch computer monitor in front of her. A narrow corridor, too narrow for two people to pass by each other, led from her station to the sealed module hatch and connecting tunnel. The air had the faint smell of ozone, electrified air and sweat.
But soon after beginning work on Silver Tower, Ann had learned to ignore such things. She had no room to work in because she had four times more equipment than any other scientist or any other project ever had before. Today all the hard work and sacrifice… if that's what it had been… was about to pay off. Or so she hoped… "Skybolt is ready, Control," she reported. "System is on full automatic."
"Copy, Skybolt," Saint-Michael said over interphone. "Good luck."
"Thank you, sir. Thirty seconds."
She made one last systems check. Her master computer would make a three-second self-test of the superconducting circuits, microprocessors and relays under its control. The results of the self-test flashed on her screen: all systems go. It was working, Ann thought. It was working perfectly.
"It's not working." Chief Master Sergeant Jake Jefferson pointed to his large two-foot by three-foot rectangular display screen, representing the one-thousand-mile scan range of Silver Tower's huge space-based, phased-array radar. He had electronically squelched out all objects detected by the SBR that were less than five hundred pounds, all ground returns and all previously identified objects; even so, the screen was filled with blips. Each blip had a code assigned to it by Silver Tower's surveillance computer. On the margins of the rectangular screen, data on the object's flight path and orbit were displayed. Any object within fifty miles of Silver Tower's orbit was highlighted. The tech pointed to the nearest such object on the screen. "There it is, Skipper." Saint-Michael maneuvered himself around to the screen and anchored himself on the Velcro carpeting.
It was an Agena-Three cargo spacecraft, one of the small fleet of unmanned modules used to resupply the American and European space platforms. This one had been fitted with detection-and-analysis equipment as well as sensors to record laser hits made against it. The Skybolt computer had already been programmed to consider this Agena "hostile." For the next three hours the Agena would follow a track similar to the track a Soviet ICBM would follow from launch to impact in the United States.
"Altitude?"
"Five hundred on the nose." Jefferson pointed to the object's flight data readout, which had just appeared. "We should be picking up its identification beacon any sec—"
An extra three lines of data printed themselves just under the flight data block, identifying the newcomer as an Agena-Three unmanned spacecraft launched from Vandenburg and belonging to the United- States Space Command. The information remained on the screen for three seconds, then disappeared as the computer squelched off the identified. "Bring it back," Saint-Michael said. Jefferson punched two buttons on his keyboard, rolled a cursor over to the spot where the blip had been and pushed a button. The Agena's blip and data block returned.
"Skybolt hasn't keyed on it yet?" Saint-Michael asked.
"Negative."
"Maybe it squelched it out."
"Skybolt doesn't squelch out any targets," Colonel Walker reminded Saint-Michael. "It's supposed to track and evaluate everything detected by the SBR. If it's considered hostile, it's supposed to act."
"Maybe Skybolt wasn't reprogrammed to consider it a hostile," a technician, Sean Kelly, said.
"Or maybe Skybolt is screwing up," Saint-Michael said. Jefferson nodded in agreement, then keyed his interphone mike. "Skybolt, this is Control."
Saint-Michael grasped his shoulder. "Don't, Jake. Let's see what Skybolt does."
"Go ahead, Control," Ann replied.
Jefferson looked at Saint-Michael, then at Walker. Walker shrugged, silently deferring to his commanding officer. "Disregard," Jefferson said, and clicked off his mike.
The group watched as the Agena spacecraft marched across the screen. The SBR tracked it easily. "Still nothing?" Saint-Michael asked. "Not yet," Jefferson said. "Target on course. Thirty seconds to midcourse transition…"
Suddenly the station's warning horn blared, crowed three times; then a high-pitched computer-synthesized voice announced: "Attention on the station. Tracking hostile contact. Tracking hostile contact."
"About thirty seconds late, but it finally found it," Walker said.
"Skybolt transmitting warning message to Falcon Space Command headquarters, sir," the communications officer reported. A pause, then: "Falcon acknowledges."
"So we have a machine fighting our battles for us," Saint-Michael muttered. "Damn thing even makes radio calls."
"Attention on the station" — the computerized voice. "Impact prediction on hostile contact. Impact prediction on hostile contact."
"It's finally figured out what's going on," Saint-Michael said. "Well, let's see how well it reacts."
"Coming up on midcourse transition," Jefferson reported. "Thirty seconds to simulated warhead-bus separation."
The Agena would not actually release any warheads, but the spacecraft's orbit had been sequenced like a real ICBM to monitor Skybolt's performance. The goal was to destroy the ICBM as early as possible, either in its very vulnerable boost phase or at the latest at the apogee — the ICBM bus's highest altitude in its ballistic flight path. Once past apogee the target would become increasingly difficult to hit. "Skybolt had better damn hurry," Walker said. "The thing will MIRV any second… "
