A World’s Eye View – 7

He found Vyhovsky in the room, drifting in the middle, having fallen asleep and lost his foothold. Normally, this would be something that would amuse Thompson and the others, but right now, it seemed to punctuate how much stress everyone had endured to date, and how much more they might have to in order to survive in this hostile environment. The metal and plastic of the station against the unforgiving vacuum of space and debris of the disaster below. Thompson carefully slid by the sleeping Vyhovsky, settling into an ergo chair, and going over the open command list. He’s calculating the burn needed for a slow rise up another 3 kilometers, trying to get above all this debris before we hit a big cloud of larger pieces. He looked over at another file opened to one side of the screen. What’s this? Hmm, how much maneuvering fuel we have for the station?

He sat down, ducking under Vyhovksy’s slowly rotating legs as he reviewed Vyhovsky’s spreadsheet. Enough to lift us up a total of forty kilometers, then we start to decay into the atmosphere. He’s got an estimate of four years here. So a lot of time, just not enough to stay up here indefinitely, though I guess four years qualifies. He tapped and opened a second sheet, which displayed figures for food, recyclables, electrical reserve, and ammonia reserves. After looking through the sheets, it was clear that the two things that were the true limits were the ammonia, and food. Each was finite, though vegetables could be grown with some effort, as was proven in previous missions to the station. The real kicker, as he’d thought early on, was going to be ammonia for heat dissipation. He’d guessed about six months. Vyhovsky had actually quadrupled that to two years, basing his estimate on reducing the electrical reserve even further, and allowing a ten degree extra rise and fall in onboard temperatures to reduce ammonia use. It all worked out on paper. The trouble with all this is none of it could predict anything about likely micrometeorite strikes or the new large orbital pieces from the exploding EMP warheads.

Thompson bit his lip, depressed by the estimate. It’s one thing to guess, but not have a solid date. Gods I’d rather have it a maybe, than a definite. We’re going to die up here, unless we can get home. Hell, we’ll probably die there. But we’d be home, not in this freakin’ hamster house. God, if you’re out there, we could really use some good news right now. Something, anything. I don’t want to die up here. He pinched his nose, then reached up in surprise as Vyhovsky’s legs rotated into his peripheral vision. His outstrectched hand thumped against Vyhovsky, who awoke with a startled grunt.

Thompson watched him come awake, and groggily take a moment to orient himself. He reached up to a hand hold, helped by a slow push from Thompson. Thompson watched his gaze alight on him, then the open spreadsheet on the computer on the wall behind him. “Reading over someone’s shoulder isn’t proper etiquette.” Thompson found himself smiling as he replied. “And sleeping on the job gets the boss upset”, he replied, which earned a tired smile from Vyhovsky. He grimaced dramatically, then stated, “I’ll keep quiet about the reading, if you keep quiet about the sleeping.” “What sleeping?”, Thompson replied innocently. “…”, Vyhovsky started to reply, then realized the joke, and chuckled softly. “How tired am I that I could not see that coming?”

Seriously? I’d say quite a bit if you end up hovering in the middle of the room”, Thompson answered. “What have you been doing to get to this point?” He looked up at Vyhovsky, then back over to the open spreadsheet. “The Ammonia lasting twenty-two months? Isn’t that optimistic?” Wyhovsky shrugged. “If, we catch all the breaks, then it’s close to realistic. If not, then we’re pretty much dead anyway and there’s no reason for the exercise.” Thompson looked back at Vyhovsky, who gave another tired smile. “I’m Ukrainian, we’re bigger pessimists than the Russians.”

Vyhovsky pushed away from the handhold and floated down to grab the back of the chair Thompson sat at. He peered at the spreadsheet. “What is the rate of consumption for the Ammonia?” Thompson minimized the spread sheet then searched the database for recharge cycles. “We’re using this much here, and this spike is when everything happened back home. We lost a heft chunk from the reservoir.” He shifted in the chair to let Vyhovsky see the chart more easily. Vyhovsky eased himself forward, grasping the edge of the computer mounting to arrest his motion. “So we have what, forty percent of the reservoir left”, he asked Thompson. “More like thirty. Cutting back on the heating and cooling will stretch it, but we may end up having more stuff breaking down because of thermal expansion and contraction in here.”

Thompson popped the spreadsheet open once more. “The trouble is, skrimping one place will hurt in others. Reduce the heating and cooling, that will help, but the equipment isn’t exactly made for temperature cycles. It’s sturdy, and we’ve got triple redundancy and spare equipment, but no telling how long it will last with the thermal changes.” Vyhovsky nodded, intent on the spreadsheet. “So your best estimate of our time here?” Thompson stared at the spreadsheet, then cycled through the other tabs for food, recyclables, and perishables. He changed the formulas used, and then jumped back to the main page to display the estimates. It looked nowhere near as encouraging as Vyhovsky’s. Ammonia was still the major bottleneck, at eleven to fifteen months before reserves ran out, if Vyhovsky’s measures were instituted.
