Big Alice was always hungry.
And with her skilled hands on the controls it was Stephanie "Roulette" MacBaren's job to keep the big bitch fed.
Following a path laid down by two seasons of steady work, Rue guided the insanely massive paddle wheel excavator on its way up and over a lobate scarp that made the big machine work for its meal. The slow turning blades in the front -- each "tooth" carving out a three-ton scoop of powdery silica regolith and tossing it into the hopper as they rotated -- dug the offending hillock down another ten feet as they and the treads dragged "Big Alice" up the stony face and over. With a jar, the massive machine settled back onto the more leveled ground and moved forward more easily.
Eating more and more of the surface of Mercury as it went.
The speaker above her head crackled and squawked.
~"Roulette?"~
Grabbing down the mic, Rue put it close to he lips and pressed the side button. "Yeah, Minnow, what the hell do you need now?"
~"What the fuck was that?"~
A sound like metal on metal clattered through the speaker.
~"You just jarred all the tools out my toolbox down here! I'm trying to rebuild chiller three and now I've got parts and spanners scattered all to hell and gone."~
"Sorry about that. Alice just took another bite out Hill-167424." Another shuddered quaked through the excavator, but then it leveled and rumbled forward at its normal steady pace. "It's all flatlands for the 20 hours, give or take."
~"Rodger that. Just no more wheelies, how about it?"~
Rue laughed at the idea of a 65ton -- Mercury-weight, at that -- excavator managing a "wheelie" in any fashion. Hanging up the mic, she checked her rear cameras. Hill-167424 wasn't even half the mountain it had been, to begin with, but the monitors showed the trailing ass of "Big Alice" crawling caterpillar-like over the smaller bump. A hod-tender robot peeled away from its flanks and scooped up the compacted "shit-brick" of Mercury ore that Alice had dropped in its wake and darted away at speeds the big crawler could only envy. Roulette absently watched it go, a grin at the cha-ching sound of credits in her pocket it represented.
The spidery hod-tender vanished out of sight, racing to meet up with the mag-lev train that would ferry the block of ore -- and five thousand of its rocky brothers -- up the cable line and into orbit.
Check the radar, Rue saw that the two excavators on her flanks -- Charley Bucket and Black Betty -- were struggling to keep within a mile of the faster A-Rig. Fat Mabel and Dopey were all but lost off the screen. With a smile, Roulette picked up her cup and took a sip of tepid coffee.
Leaving the controls, Rue took the offending cup to the battered auto-chef and got a refill. The scorching hot brew was just what she needed given all the easy driving coming up. Looking out the windows at Mercury passing by had lost its appeal after the first year, but the surface of dead scorched Mercury at night was all there was to look at.
Well, she could check the news, but that was about a stale and boring as a radiation-blasted hunk of rock.
~ "B-Rig actual, calling A-Rig. You got your ears on up there?"~
Going back to her command chair, Rue dropped down and grabbed up the mic. "Yeah, talk back at me B-Rig. How the Dust?"
~"Yeah, yeah, laugh it up. Look I've got Black Betty pegged out to the red line. How about slowing that behemoth-mother down a peg?"~
Rue grinned and nudged Big Alice's speed another notch forward. "Worried I'll leave you for the scorch?"
~"No. Worried you will drink all the gin at base-camp before I get there."~
Roulette settled back and watched the monitors. She pulled up the magnification on the high gain and zeroed in on Black Betty. The sun-scorched excavator an inky shadow in the trailing dust cloud that A-Rig was spitting out. Her pilot, Wayne Gunn, would be cursing her name and calling A-Rig names all shift given the dust he was having to drive through.
She cued the mic "Now, you know I'm more of rum girl, B-Rig."
~"HA! Yeah, like we've got rum. Let me tell you--"~
A loud squeal-squawk cut through whatever it was he had been about to say.
~"Cut the chatter. Keep the channel cleared for emergency communications only."~
A warning light lit up on the dash of Big Alice's control board, next to her speed indicator.
~"A-Rig, dress the line."~
Rue snarled at the officer-in-charge. "Suck the piss stains out my panties, you fucking station-hugging prick." Taking a slow sip of her coffee she picked up the mic. "Rodger that, Base. Was only gunning it to get over Hill-167424. Idling back to standard."
That he didn't answer her back showed her the contempt her boss felt for her and all the other excavator drivers in a way that nothing else could have. Roulette, returning that contempt with gusto, eased A-Rig down to a lower speed and eased back on the speed of the massive cutting wheel.
~Roulette?"~
Cuing the mic for inner-rig communications only, Roulette pressed the side button. "Yeah, Minnow, what now?"
~"I heard a change in engine pitch, we slowing down?"~
The excavator's chief mechanic had a twin to all of her control panels down there with him but apparently, he found it easier to bug her that to check his own instruments. With a sigh, she picked back up her coffee and sipped it.
