They were close enough now for Greg to make out the blimp’s slender monolattice tether cables. A clear flexible pipe ran up one of them, refracting rainbow shimmers along its entire length. Hydrogen electrolysed from seawater by the thermal-exchange generators would be pumped up it, refilling the Alabama Spirit’s MHD gas cells.
The probe shuddered into the collar, which closed about it with a loud clang, reverberating through the Alabama Spirit’s fuselage struts. Greg had seen those struts when he embarked, arranged in a geodesic grid, no wider than his little finger. The fibres were one of the superstrength monolattice composites extruded in microgee modules up at Zanthus or one of the other orbital industry parks. It was only after those kind of materials had been introduced that airships became a viable proposition once again.
Greg and Victor Tyo took a lift up to the Alabama Spirit’s flight deck, a recessed circle in the middle of the upper fuselage. The other five members of the security team were waiting for them, along with a cluster of Event Horizon personnel who were beginning their three-month duty tour at Listoel.
A handling crew were loading a matt-black environment-stasis capsule into the cargo hold of the tilt-fan standing in the centre of the flight deck. Greg could see radiation-warning emblems all over the cylinder. He knew it contained a Merlin, a small multi-sensor space probe riding a nuclear ion-drive unit, designed to prospect the asteroids. Philip Evans had been launching them at a rate of one a month for the last three years. Greg had listened to him explaining the programme at his dinner party, clearly in his element, with an audience which hung on every word.
“Investing in the future,” the old billionaire had said over after-dinner brandy. “I’ll never see a penny back from them, but young Juliet here will. I envy her generation, you know. We’re poised on the brink of great times. Our technology base is finally sophisticated enough to begin the real exploitation of space. My generation missed out on that; we were hopelessly stalled by the crises at the turn of the century-the Energy Crunch, the Credit Crash, the Warming, the disaster of the PSP. They all put paid to anything but the immediate. But now things are stabilizing again, we can plan further ahead than next week, set long-range goals, the ones with real payoffs. Unlimited raw materials and energy, they’re both out there waiting for her. Just think what can be achieved with such treasure. The wealth it’ll create, spreading down to benefit even the humblest. Fantastic times.”
Philip Evans’s corporate strategy had Event Horizon flourishing into one of the leaders in deep-space industry. And the Merlins were an important part of his preliminary preparations; prospecting the Apollo Amor asteroids for him, a class of rocks well inside the main belt and the most easily accessible from Earth. The Merlins sent back a steady stream of securely coded information on their mineral and ore content.
When the consortium of German, American, and Japanese aerospace companies finally rolled their scramjet-powered spaceplane out, launch costs would take a quantum leap downwards. The single-stage launcher would open up a whole panoply of previously uneconomical operations. One of which was asteroid missions.
And with its carefully accumulated knowledge of extraterrestrial resources Event Horizon would be in the vanguard of the mining projects, so Philip Evans said. In a prime position to feed refined chemicals back to the constellations of microgee material-processing modules projected to spring up in Earth orbit.
Greg had been aware of an undercurrent of dry humour in the old man’s mind as he expanded his dream, as though he was having some giant joke on his guests. But the Merlin was real enough. It was just that the whole enterprise seemed whimsical, or at best premature. There had been rumours about the spaceplane, now eleven years behind schedule; some said scramjet technology just couldn’t be made to work, and even if it could the cost savings would be minimal.
Greg’s status earned him a seat at the front of the tilt-fan’s cramped cabin, looking over the pilot’s shoulder. She lifted them straight up for fifty metres then rotated the fans to horizontal and banked sharply to starboard.
He’d been right. In the light of day the Alabama Spirit was spectacular. A huge jet-black ellipse framed by the dreaming sky, like a hole sliced direct into intergalactic night. It was four hundred metres long, eighty deep, sixty broad. Two contra-rotating fans were spinning slowly on the tail, keeping its nose pressed firmly into the refuelling blimp.
Their descent in the tilt-fan was a long spiralling glide. Even here, where energy shortage was a totally redundant phrase, the pilot was reluctant to burn fuel. She must’ve been a European, Greg thought, obsessive conservation was drilled into EC citizens from birth.
They flattened out at the bottom of the glide and lined up on one of the big cyber-factory ships, swinging over the bow and pitching nose-up as the fans returned to the vertical. Greg read the name Oscot painted on the rusting bow in big white lettering.
The Dornier settled amidships with minimum fuss, its landing struts absorbing any jolts.
Greg tapped the pilot’s shoulder. “Smooth ride. Thanks.”
She gave him a blank look.
He shrugged and climbed out.
Sean Francis, Oscot’s manager, nominally captain, was waiting at the foot of the airstairs. He was tall and lean, dressed in a khaki shirt and shorts, with canvas-top sneakers, broad sunglasses covering his eyes.
Greg dredged his name up from Morgan Walshaw’s briefing file. Thirty-two years old, joined Event Horizon straight out of university, some sort of engineering administration degree, fully cleared for company confidential material up to grade eleven, risen fast, unblemished reputation for competence.
He reminded Greg of Victor Tyo; the resemblance wasn’t physical, but both of them had that same hard knot of urgency, polite and determined.
The security team spilled out of the tilt-fan to stand behind Greg, waiting impassively. Sean Francis looked at them with a growing frown.
“My office was told you’re here to check on our spaceflight operations, yes?” Sean Francis said. “I’m afraid I don’t understand, the Sangers are a mature system. I rather doubt their flight procedures can be improved after all this time.”
Greg produced the card Walshaw had provided, which Francis promptly waved away. “It’s not your identity I’m questioning,” he said, “merely your purpose. OK?”
“This is not the place,” Greg said quietly. “Now would you please verify my card.”
Francis held out his cybofax, and Greg showed his card to the key. There was an almost subliminal flash of ruby light as the two swapped polarized photons.
He took his time checking the authorization before nodding sadly. “I see. Perhaps my office would be a more suitable venue. Yes?”
The seven of them started down the length of the deck towards the superstructure, drawing curious glances from Oscot’s crew.
Instinct made Greg look up towards the south-west. There was a black dot expanding rapidly out of the featureless sky, losing height fast. It was a returning Sanger orbiter, curving in a long shallow arc, pitched up to profile its sable-black heatshield belly. Greg tracked its descent, working out that it would reach zero altitude right at the end of the floating runway. He held his breath.
The orbiter straightened out three hundred metres from the runway, wings levelling. It smacked down on the concrete, blue-white plumes of smoke spurting up from the undercarriage. Small rockets fired in the nose, slowing its speed.
“What if it missed?” Greg asked. The orbiters didn’t have a jet engine, they couldn’t go around.
“They don’t,” Sean Francis said.
