Conversation descended into technical matters and broke apart by topic, before they saw a general return to work and research. The two newcomers were permitted to wander the archaeological camp, provided they didn't stray into hazardous areas like the thermal bore site, nor interfere with archaeology. And if they hung about too long, they would soon be recruited into the scientific grunt-work of processing data, cutting through ice, and setting up equipment.
It wasn't long before Borys was ready to fire up the
Yermak Maru's engines. Everyone outside had to wear protective goggles against the glare, and stay away from the aft end of the ship. Inclined toward the ice-sheet, the rocket thrusters unleashed a searing gout of fire and superheated gas. The whole ship strained and groaned, its landing gear bolted to the ice, not designed to fly like this anyway. But she was a tough ship, and she held.
The thermal bore drilled through the frozen atmosphere like, well, a blowtorch through an icecube. Ice flowed into liquid evaporated into gas, lost in the flame. They couldn't see the hole itself being bored, but knew it was descending in a matter of seconds.
After several seconds of this, Ortega called a halt, they waited a few long minutes, and Vax conducted some scans. At Ortega's word, Borys fired up the engines again, and so they steadily crept closer down to the buried and frozen alien city they'd all glimpsed through the ice.
Eventually, Vax and Ortega deemed they were close enough, the engines were shut down altogether to cool in the chilly air. A perfectly round shaft had been cut into the ice, the angle steep but enough to walk on. It descended into the earth, first in the weak daylight, then shadowed eerily by light refracted through the ice, before disappearing into an blackness. Misty vapours rose out of the hole, and icy stalactites had begun to reform on the top lip, for all the world like the gaping mouth of some buried behemoth.
Now they waited for the ice walls of the borehole to refreeze, forming their own structural supports.
Now it was time for the workers to set up plasma torches. Without firing up the thrusters, heat from the ship's engines would be channelled down insulated tubes to the plasma torches, which would be used for finer cutting through the ice. They would also need to set up heaters to warm up and expand ice caves beneath the surface. Those who would go down the hole hauled on protective suits, pulled on sturdy friction boots, and helmets with mounted cameras.
Vax Kent and Hali Plim were to be the first to go down the borehole, though anyone could choose to accompany them, whether for technical work, scientific consultation, or just the thrill of being among the first to enter a lost alien city. Professor Ortega had, at great reluctance, elected to stay topside and supervise the initial foray via communicator, watching what would take place over the helmet-mounted cameras. He'd emphasised that the newcomers would be most
useful if they put on protective suits and help Vax and Plim tunnel.
And, after all, who wouldn't want to squeeze into a cramped, heavy suit, then wriggle down through nearly two kilometres of narrow icy tunnel, dragging a metal tube behind you all the way, and then finally stand there blasting plasma energy at a wall of ice, completely surrounded by roaring jets of high-pressure gas? It's for archaeology!
As they waited, Vax waved Trace and Sky Light and whoever cared to join them to a pool of clear liquid nearby, the run-off from the borehole. Misty vapours rose off the softly bubbling liquid.
'Hey, look at this. Liquid nitrogen, mostly. Boils at minus 196 degrees C. Cold enough to burn.' He dipped his sonic trowel into the pool, provoking furious bubbling and a gust of vapour.
'Icehot!' Sky Light declared.
'Icehot, yep. What would happen if you stuck your hand in there?' Vax wiggled his gloved hand over the surface, apparently making a safety demonstration.
