Sal and Kazuo marched inside and each stepped up to a mechanical docking clamp, which held MASPECs while their pilots climbed out. A person wasn’t strong enough to remain upright once the suit powered down, and attempts to escape were quite comical when they didn’t result in serious injury.
Sal pulled herself out of the back of her suit and retrieved the faulty circuit board from its hip-pack while Kazuo was still going step-by-step through the power-down procedure. As usual, she found his tenacious grip on procedure endearing in a ridiculous sort of way.
Her comm headset rang. “Yeah?”
“Hey Sal, it’s Rachael. Are you back yet?”
That was Rachael Peretz, a communications operator who—like Sal—had come to Mars as a child with the first wave. Sal had babysat her once upon a time, and they were close friends now. She silently hoped this wasn’t another gab session about the cute sounding boy on the Shackleton Expedition. She didn’t think she’d survive another one of those.
“Just climbed out of my suit. What’s up?”
“Something weird. Can you come to the Comm Center and give me a hand?”
A technical mystery. Sal considered it a minor blessing. “I’ll be there in five. Saladin out.”
She snatched the duty jacket from her locker and took off on an Ares sprint. With gravity only a third of Earth’s, the Martian colonists had learned to run upwards of forty kilometers an hour, and jump several times their own height. It was one of the skills that separated long time colonists like Sal from more recent transplants like Kazuo, who’d dislocated his shoulder several times trying.
Sal flew through one corridor after the next, and then started braking by leaning back and scraping her feet along floor. The motion was rather like skidding down a long hill. She came to a perfect stop in front of the Comm Center door, and it slid open in front of her.
“Hey, what’s going on, Rache?”
Rachael waved her over, and Sal stepped up to her friend’s workstation. The screen showed a graph of a waveform drawn in sharp right angles. It was a digital signal. “Alright. What am I looking at?”
“It all started two days ago. The infra-red receiver blacked out, and at first, we thought it might be solar flare interference, but then it started to happen regularly. Each blackout lasted forty-five minutes, followed by the receiver returning to normal operation for forty-five.”
“Weird.”
“Yeah, I thought so too. Some of us thought it might be a software problem, or a piece of equipment faulting out.”
“But it wasn’t?”
“Nope. Turns out, we’re being hit by an infra-red laser that’s overloading the photodiode. And get this… it’s coming from Earth.”
Earth. No one was talking about it anymore. They hadn’t heard anything from home for more than two months. At first they assumed it was some minor technical problem, or a bout of nasty solar weather. Then, as the silence stretched on, theories of all sorts started to fly, from a nuclear war to some kind of global communications collapse caused by terrorists. Then the conversation just died. There was no way to know what was going on, so they stopped trying to guess.
“Once we tuned down the receiver’s sensitivity, I started analyzing the beam, and I found this signal embedded inside.” She pointed to the screen.
“And you think someone’s trying to talk to us?”
“Yeah, I’m pretty sure. I haven’t been able to decode it, though. I was hoping you’d take a look.”
Sal realized her jaw was hanging open. She closed her mouth and stared at the screen for a moment, and tried not to imagine what it could mean. “Yeah. I’ll do that,” she said. “Add me to the comms working group, and I’ll take a crack at it.”
“Thanks,” Rachael said, “and until we know what’s going on, let’s keep this quiet, alright? No need to panic anyone.”
“Sure thing,” Sal said, and she stayed for several long minutes, watching the peaks and troughs of the signal stretch across the screen.
Chapter 20:
A Call to Arms
Marcus Donovan was deep inside Legacy’s secondary hull, her factory complex. From the observation platform where he stood, he looked out over a cavernous chamber lit in blue-green and filled everywhere with activity. The Shackleton Explorer was there, docked inside a series of orange constructor rings whose countless biomechanical arms twitched about and inspected the vessel. Legacy wanted to know more about human technology, and they both agreed the most direct route was to take a closer look. Faulkland was against it at first, but after six weeks of constant badgering, he finally caved and reluctantly allowed his boat to be brought inside.
The last of Shackleton’s crew moved to more comfortable quarters aboard Legacy, although the engineering team maintained a presence on the Shackleton to monitor its nuclear reactor. The chief engineer, Olli Enqvist, insisted the reactor was perfectly safe and could operate itself, but he preferred to err on the side of caution. Marcus smelled subtext.
All the while, Legacy was in a state of transformation. She had been quiet and despondent when she woke up, but the crew’s presence raised her spirits. Marcus didn’t completely understand it, but humans invigorated her somehow. She had been incomplete without them; now she was filled with purpose and an eagerness to please.
Legacy’s factory especially had become a constant hub of activity. She quickly constructed a small fleet of utility vessels shaped like pill-bugs, which the miners called tugs and adopted as their own. With the miners as their pilots, the tugs swarmed out to assay and retrieve asteroids, feeding them to the factory complex which hungrily digested tonne after tonne of ore. This led to the construction of yet more tugs, some of which joined in acquiring minerals, while others went about repairing Legacy’s hull.
Repairs across Legacy were moving faster than anyone expected, thanks primarily to the efforts of Juliette St. Martin, whose insights into the alien technology were unmatched by any of the engineers. Legacy’s internal systems more closely resembled biological structures than they did machines, and healing her was more like medicine than car-repair. Being an exceptional physician with plenty of experience and a keen interest in alien biology, Juliette was the perfect woman for the job.
Marcus suspected Juliette and Legacy were bonding in ways he never could, and the ship all but confirmed it. She was in fact growing quite fond of the doctor, and Marcus felt a twinge of jealousy which he realized was utterly absurd. The most confounding part was that he couldn’t figure out which of the two he was more jealous of.
The rest of the team were busy adapting their equipment to Legacy by trial and error. Mostly error. The ship learned to produce compatible electrical outlets after a bit of practice, so power wasn’t an issue, but all attempts to mate their computers to her information network failed. They were forced instead to setup their systems in tandem with hers, including a comm system which she essentially ferried signals to and from. Rao likened it to visiting a cutting edge radio-telescope and then being forced to use one’s own Victorian spyglass.
As Marcus stood there in the factory watching the machines do their work, Legacy repeated a request which she’d made a dozen times already. She explained that whole swaths of her memory had faded during her eons-long slumber, and she needed new patterns to fill in the gaps. Specifically, she wanted to dismantle the Shackleton and analyze its construction. She was sure she could interface with the crew more easily if she could better mimic their technology.
