The Astronautics Institute had been visible as a gleaming blister on the horizon ever since the Duo passed junction eleven outside Cambridge. After that Greg found himself constantly readjusting his perspective to accommodate the size of the thing. It was huge.

He'd spent a few minutes the previous evening reviewing the data which he'd been given at Wilholm. But it'd completely failed to prepare him for what he was seeing now.

The main building was a five-storey ring of offices, research labs, and engineering shops, eight hundred metres in diameter, presenting a blank wall of green-silvered glass to the outside world. The area it enclosed had been capped by a solar-collector roof, giving the staff a voluminous hangar-like assembly hall for space hardware.

Construction crews were still finishing it off; two motionless cranes stood on opposite sides, piles of scaffolding littered the raw packed limestone surround, ranks of silent contractor vehicles were drawn up across the parking yards. Standard transit containers full of Event Horizon's own cybernetics were stacked outside the assembly hall's sliding doors, waiting to be installed. A saucer-shaped McDonnell Douglas helistat hovered overhead, its five rotors generating an aggressive down-draught as it struggled to maintain its position against the light north-easterly wind. A container was being winched down out of its belly hold, swaying like a pendulum in the gusts. Two more helistats waited high overhead.

Greg could see machinery and gear being moved from their temporary accommodation in patched-up Museum buildings into the Institute. With the bulk of the structure complete, Event Horizon's research, design, and management teams were starting to take up permanent residence.

A ragtag army of scrap merchants had been let loose on the old airport, piling vans and horse-drawn carts high with the twisted shards of metal which were still strewn across the runway and taxi lanes. One of the merchants had modified an old street-cleaning lorry to sweep up the thick stratum of rust, and a dense cloud of orange dust foamed up from its bald tyres as it thundered up and down the concrete strip.

Philip Evans had built his mindchild with an eye to the future. Its proximity to the University colleges had proved subversively addictive, offering finance and top-range research facilities to budget-starved faculties. A move which put the cream of the country's intellect at his disposal.

Physically, the Institute was a totally self-contained complex, taking the concept of centralisation right to its extreme. It could design and fabricate mission hardware ranging from torque-neutralising screwdrivers for orbital riggers right up to the refineries which would latch on to asteroids and leach out the ores, minerals, and metals. Independent and efficient. And with the money the giga-conductor royalties would bring in, Greg realised, quite capable of achieving the space-activist dream: exploiting the solar system's wealth.
