East of the Sun, West of the Moon tcw-4 Page 7

  “Are you sure this is going to work?” Herzer asked, slowly raising a barbell in one hand and another in the prosthetic up to shoulder height, arms outstretched in front of him. He took a slow breath as he raised them, then held them out at full extension. He was wearing cutoff shorts and a sweat-soaked, sleeveless, gray cosilk shirt.

  “If I can get in here around your stuff, yes,” Meredith said coldly. She dropped the files in her arms on the desk and sat down, opening up the top one. “And if I don’t have to engage in casual conversation.”

  Herzer took the hint and lowered the barbells with an outrush of breath, waited a moment and then repeated the movement.

  He was halfway through a forty rep of slow curls when Meredith closed the file she was reading and turned around in her chair.

  “Aren’t you supposed to do a lower body workout one day and an upper body workout the next?” she asked scornfully.

  “I did a heavy lower body today,” Herzer said, slowly raising the twenty-kilo barbell. “This is a light upper body workout.”

  “That’s light?” Meredith said, frowning.

  “Yes,” Herzer replied.

  Meredith watched him for a moment and then turned back around, opening another file.

  “Thanks for coming over here, Evan,” Herzer said, helping the engineer with the easel he had brought.

  Evan Mayerle was a medium height, brown-haired young man with blue eyes that at the moment were mostly focused on Shanea’s rump. She had brought in a tray of coffee and sweet rolls and placed them on the low table by bending over from the waist. Since she was wearing a tight skirt, her endowments in the area were fully evident.

  “Uh…” the engineer said. “Yeah. Uhm…”

  “Briefing on the Excelsior,” Herzer said, grinning.

  “Right,” Evan said, shaking his head and trying not to watch the blonde as she sashayed out of the room. “Excelsior,” he muttered, pulling a set of charts out of a tube and pinning them to the easel. “Excelposterior…” He paused and shook his head. “Miss Travante, have we met?”

  “Briefly on the Hazhir,” Megan replied.

  “Nice to see you again,” Evan muttered, his eyes wandering between her chest and her eyes. He shook his head again and pulled out two thick files from his briefcase.

  “I suppose I should get started,” he said, setting the files on the coffee table. “Uhm…” He paused and took a breath again and then turned to the easel. “You’re ready?”

  “Ready, Mr. Mayerle,” Megan said, trying not to laugh.

  “The Excelsior was built in 2935. It was originally a tanker that carried hydrocarbons from Neptune to Terra.”

  Herzer started to open his mouth and then closed it. Evan, concentrating on his notes, didn’t notice.

  “It was refitted for helium three transport in 3212 when the market for hydrocarbons dropped below the sustainment level for the system. As the last of its class it was retained while the others were scrapped. It uses an ion drive propulsion system which, of course, is very low impulse but has a high maximum speed…”

  “Excuse me,” Herzer interjected. “I’m lost. What is an ion drive?”

  “You know what ions are, right?” Evan said, frowning.

  “Yes,” Megan said.

  “No,” Herzer replied at the same time.

  Evan sighed and thought for a moment.

  “You do know that an atom is composed of a nucleus and an electron shell, right?” he asked.

  “That I know,” Herzer admitted.

  “Okay. Ions are atoms that have had the electron shell stripped away. They’re highly energetic and you can push them out the back of a space vehicle and they give you specific impulse. That is, they push the spacecraft. More or less.”

  “Okay,” Herzer said. “So that means… what for us?”

  “Just that that’s the ship’s main drive system,” Evan replied, frowning.

  “And that matters to me… why?” Herzer asked.

  Evan opened his mouth and then closed it, looking nonplussed.

  “Herzer,” Megan said, smiling faintly. “Let him talk.”

  “Okay,” Herzer replied, leaning back. “Just wake me up when we get to the part where I kill people.”

  “The ship is a bit over one kilometer long,” Evan said, frowning slightly and pointing to the first schematic. “The drive system is to the rear and takes up about two hundred meters of the ship. There are six very old model HE3 fusion reactors in that section and the ion generator cannon…”

  “Cannon?” Herzer said, sitting up.

  “It’s a term of art, Major,” Evan sighed. “It’s not a weapon.”

  “Oh.”

  “There is also a small control facility that controls only the main engine systems. The ship vector is adjusted by latitudinal thrusters located along the midline and centerline…”

  Herzer opened his mouth and then closed it, shaking his head.

  “That’s how it’s steered,” Megan whispered in his ear.

  “… which are controlled from the ship’s central command facility located… here,” he said, pointing near the center of the ship.

  “Why’s it got those big bulges?” Herzer asked.

  “There are three HE3 tanks,” Evan said, sighing. “Located centerline of the ship. Each is composed of a flex-metal composite. When empty they deflate but they will be fully engorged when the initial presentation is made.”

  Herzer started to say something again and then waved his hand in despair.

  “That means when we first get up there,” Megan whispered.

  “There are twelve refueling shuttles,” Evan continued, apparently not noticing the byplay. “Located midline at docking points here, here, here, here, here and here,” he added, tapping the new schematic. “This, of course, only shows the shuttles on one side, there is a matching set on the far side. Each of the shuttles has room for seven persons including a pilot, in case the ship needs human repair crew…”

  “Why in the hell would it need that?” Herzer asked. “Doesn’t Mother handle that?”

  “At the time it was developed,” Evan said with a moue, “full function AIs were limited in number and not fully trusted with complex problems. The ship originally had a human crew. Which is why the transverse personnel tubes located midline above the shuttle docking points are pressurized, as is the engine control room, maintenance, crew quarters and the main control room.”

  “Okay, now we’re getting someplace,” Herzer said, leaning back and rubbing his chin.

  “The shuttles are fully automated,” Evan continued. “When the ship approaches Terra…”

  “Where’s Terra?” Herzer asked. “You said that before.”

  “Earth,” Megan replied.

  “What she said,” Evan said with a nod. “When it approaches Earth, the shuttles fuel from the HE3 tanks and land at reactors. Transfer at the reactors takes approximately one hour. Then they return to the ship, fuel again and so on. It takes approximately twenty trips for the ship to be fully emptied.”

  “Why not just port it down?” Herzer asked, confused.

  “The ship, for safety reasons, never comes closer than the orbit of the Moon to Earth,” Evan said. “The initial shuttle punch occurs far outside the orbit of the Moon and the ship continues on trajectory past Terra and the Moon. It’s far enough out that even modern porting systems are questionable and a portal, since it moves at a high rate of comparative velocity to a link on Earth is highly unstable. When the system was designed, of course, teleportation had not yet been developed.”

  “So we can’t just set up a portal and flood the ship with troops,” Herzer said.

  “No,” Evan confirmed. “The only way up, and the only way back is on the shuttles. Seven at a time, per shuttle. Nine at a real squeeze. There are, in addition, four small space-capable shuttles. They are not capable of landing on Ter… Earth. They’re designed for moving around the ship and between the ship and its fueling stations around Jup
iter and Saturn and cannot handle reentry gravitational loading. Nor are they aerodynamic.”

  “So… what’s the plan?” Herzer said.

  “The control room can reprogram shuttle priorities,” Evan said. “The original Icarus plan was to go up in the first shuttles and take the control room, then reprogram the shuttles to only refuel Freedom Coalition reactors.”

  “Sounds like a plan,” Herzer said.

  “What about the engine room?” Megan asked.

  “Anyone who controls the engine room, effectively controls the main engines,” Evan said, frowning. “But that only gives direct velocity control. I’m not sure what utility that would have to the mission. My primary concern was with the shuttles themselves.”

  “Why?” Herzer asked.

  “They can be overridden by an onboard pilot,” Evan pointed out. “We can reprogram them to land at only our reactors. But if New Destiny has pilots in them, it won’t matter.”

  “Ouch,” Herzer muttered. “This is making my head hurt. What we really need to do, in other words, is capture all twelve of the shuttles.”

  “That was my suggestion,” Evan said. “There was, however, a problem.”

  “And that is?” Megan asked.

  “Where, pardon me, ma’am, you come in. The shuttles require a security override for pilots to take control. For that matter, so does the control room.”

  “And the security can only be overridden by a Key-holder,” Megan guessed.

  “Correct,” Evan said, frowning. “So to take control of the shuttles, you will be required to go to each of them and tell them who you are. The system is a real antique. We don’t even have good mock-ups for it. That’s one of the reasons we’ll have to have some people who know old computers. There were some on the original team and they gave a presentation on the systems. Unfortunately, I don’t even have their notes.”

  “Great,” Megan said, frowning.

  “But New Destiny will be sending up their own people in their shuttles,” Herzer said. “Do the shuttles always go back to the same reactors?”

  “No,” Evan said, unhappily. “Just because you have a shuttle, doesn’t mean it’s programmed for your reactor. But if you have a pilot in it, it can be forced to go there.”

  “I have to ask this,” Megan said. “Is Mother going to intervene in this little scuffle?”

  “She shouldn’t,” Evan temporized. “As far as we were able to determine, she doesn’t have a protocol that governs security for this ship.”

  “Hmmm…” Megan mused. “Mother?”

  “Yes, Megan?” a voice answered out of the air.

  Evan reacted with surprise but Herzer just looked nonplussed.

  “You are aware that we’re planning on… hijacking the Excelsior?” Megan asked.

  “Yes,” the disembodied voice replied.

  “Are you going to tell New Destiny what our plans are?”

  “No.”

  “And I don’t suppose you’ll tell me their plans?” Megan asked, hopefully.

  “No.”

  “Are you going to interfere?”

  “Not unless the safety of Terra is jeopardized,” Mother responded. “And perhaps not even then.”

  “What does that mean?” Herzer asked.

  “I suspect it has to do with ship trajectory,” Evan said. “If the ship were to crash into Terra, it would be very unpleasant. Big boom.”

  “Okay, handy safety tip,” Herzer said. “Don’t crash the ship into the Earth.”

  “Is Evan correct, Mother?” Megan asked. “As long as we don’t crash the ship into Terra, you will not interfere?”

  “That is correct,” Mother replied. “As long as you remain within your plans to capture or destroy the ship, there will be no interference from this party. Furthermore, reentry of the Excelsior under these conditions could be described as human error. I am remanded from fixing human errors other than through specific protocol provisions.”

  “In other words,” Megan said, frowning, “if we crash it into the Earth, Mother won’t save us.”

  “That would be bad,” Evan said, quietly.

  “How bad?” Herzer asked.

  “Mother,” Megan said, puzzled. “What about explosive protocols?”

  “The impact of the Excelsior, more or less intact, would exceed explosive protocol overrides given current power reserves.”

  “Very bad,” Evan said.

  “But if we slam it in the Moon we’re good to go?” Herzer asked.

  There was a pause and Megan smiled as the computer didn’t answer.

  “But if we are forced to crash it into the Moon, there will be no repercussion?” Megan asked.

  “No,” Mother replied. “The mass of the ship is insufficient to deflect the orbit of the Moon.”

  “Thank you, Mother,” Megan said, frowning. “I really don’t want to crash the ship. Once we drain the reactors down in this damned war, we won’t even have the power left to build another ship that can go out and get the fuel we’ll need. Even if we take all the Keys we may be stuck on the planet.”

  “No,” Evan said. “If we take nine Keys we can override several protocols that will permit us to build different reactors. Then, when we’ve built up the power, we can build another Excelsior and go get the fuel we need. It will be a pain and it will stretch out the rebuild time, but we can do it.”

  “What sort of reactors?” Herzer asked.

  “The HE3 reactors can be converted to use hydrogen,” Evan said. “Which is easy enough to extract from water.”

  “Why don’t they already?” Megan asked curiously.

  “There are… unpleasant by-products,” Evan admitted.

  “Define unpleasant,” Megan requested.

  “Very radioactive,” Evan admitted. “It’s why they use HE3 instead; it has virtually no radioactive by-products. The only radiation comes from hydrogen and H2 contamination and that’s in parts per billion; easy enough to scrub in use. But if you use hydrogen you’re constantly having to replace parts that have been irradiated. It was extremely time and cost intensive at the time of their design, requiring that the parts be ground down and then reprocessed laboriously to extract the radioactive isotopes and then mixing them with glass and eventually containing them in a long-term containment facility.” He paused and his eyes unfocused as a thought hit him. “Of course, with modern replication technology, it would be easier to reprocess the materials since the replicator fields can distinguish, of course, between standard stable and unstable isotopes…’

  “Evan,” Herzer said. “The ship.”

  “Oh, right,” Evan muttered. “Uhm…”

  “So we have to take the control room?” Herzer asked, standing up and flipping through the large schematic diagrams. He noticed that they were on some type of plastic and wondered where they’d come from and how old they were. The plastic had a brittle feel to it.

  “That would be optimum,” Evan said. “But probably insufficient to guarantee success.”

  “Any way to ignore it?” Herzer asked.

  “Well,” Evan said, shrugging. “If you took all the shuttles, secured them, manned them and ensured their continued security, you’d get the fuel. But if you ignore the command center, New Destiny then has control of the ship.”

  “Lots of personnel for that,” Herzer muttered. “Where’s the control center?”

  “Here,” Evan said, pointing to the spot on the schematic. “Located between fuel blisters numbers one and two on the lower structural reinforcement ring.”

  “These are the closest shuttles,” Herzer said, pointing to the spots. He was starting to get the arcane symbology on the schematic.

  “Yes, shuttles three and four are closest,” Evan admitted.

  “Pressurized the whole way?” Herzer asked.

  “Pressure and artificial gravity,” Evan said.

  “Alternate means of egress?” Herzer asked.

  “Each of the pressure corridors, port and starboard, has airloc
ks, here and here,” Evan noted, pointing to the symbols. “There are two doors to the control room, port and starboard. Standard pressure doors.”

  “Armored or what?” Herzer asked. “What are they made out of?”

  “Memory plastic,” Evan said unhappily. “They’re rather easy to break if you squirt them with a cryogenic fluid and then give them a sharp tap with a pointed object.”

  “Cryogenic?” Herzer said, wincing.

  “Very cold,” Megan said. “Liquid helium would do.”

  “Or nitrogen,” Evan noted. “It’s what the team was going to use if they had to force the doors.”

  “No other points of attack?” Herzer asked. “What are the walls made of?”

  “You’re thinking of cutting your way into the control room?” Evan asked, aghast.

  “I’m hoping not to,” Herzer said. “I’m also hoping that New Destiny doesn’t. What are they made of?”

  “Ceramo-metallic composite,” Evan said. “Very strong, very resistant including to chemical attacks and heat. I’m not sure how you would cut it under the conditions. Repair requires a plasma torch. There are some on the ship in the maintenance bay,” he added, pointing to a spot between the control room and the engine room.

  “What are these?” Herzer asked, pointing to two spots on the reinforcement ring that were marked, he thought, as airlocks.

  “Docking points for the space-only shuttles,” Evan said.

  “Any way in there?” Herzer asked.

  “The airlock for the shuttle is attached to the ship,” Evan noted. “Someone could cut in through the wall of the ship, but it’s composite as well. It does have a view port forward, diamond composite. That would be easier than cutting the hull.”

  “I’d like to know what all these symbols mean,” Herzer said, running his hand over the schematic. “I can read a topographic map easily. This is… different.”

  “There’s a legend on the second page,” Evan said, flipping to it and pointing at the massive number of entries.

  Herzer looked at it and groaned. “This is going to take forever to understand. And we’ll want copies. A lot of copies. Are there any around?”

  “There’s one other,” Evan said, unhappily. “How many copies?”
