The Shoulders of Giants

We came to the bridge door, which opened automatically to admit us, although it squeaked something fierce while doing so; its lubricants must have dried up over the last twelve centuries. The room was rectangular with a double row of angled consoles facing a large screen, which currently was off.

“Distance to Soror?” I asked into the air.

The computers voice replied. “1.2 million kilometers.”

I nodded. About three times the distance between Earth and its moon. “Screen on, view ahead.”

“Overrides are in place,” said the computer.

Ling smiled at me. “Youre jumping the gun, partner.”

I was embarrassed. The Pioneer Spirit was decelerating toward Soror; the ships fusion exhaust was facing in the direction of travel. The optical scanners would be burned out by the glare if their shutters were opened. “Computer, turn off the fusion motors.”

“Powering down,” said the artificial voice.

“Visual as soon as youre able,” I said.

The gravity bled away as the ships engines stopped firing. Ling held on to one of the handles attached to the top of the console nearest her; I was still a little groggy from the suspended animation, and just floated freely in the room. After about two minutes, the screen came on. Tau Ceti was in the exact center, a baseball-sized yellow disk. And the four planets were clearly visible, ranging from pea-sized to as big as grape.

“Magnify on Soror,” I said.

One of the peas became a billiard ball, although Tau Ceti grew hardly at all.

“More,” said Ling.

The planet grew to softball size. It was showing as a wide crescent, perhaps a third of the disk illuminated from this angle. And — thankfully, fantastically — Soror was everything wed dreamed it would be: a giant polished marble, with swirls of white cloud, and a vast, blue ocean, and—

Part of a continent was visible, emerging out of the darkness. And it was green, apparently covered with vegetation.

We hugged again, squeezing each other tightly. No one had been sure when wed left Earth; Soror could have been barren. The Pioneer Spirit was ready regardless: in its cargo holds was everything we needed to survive even on an airless world. But wed hoped and prayed that Soror would be, well — just like this: a true sister, another Earth, another home.

“Its beautiful, isnt it?” said Ling.

I felt my eyes tearing. It was beautiful, breathtaking, stunning. The vast ocean, the cottony clouds, the verdant land, and—

“Oh, my God,” I said, softly. “Oh, my God.”

“What?” said Ling.

“Dont you see?” I asked. “Look!”

Ling narrowed her eyes and moved closer to the screen. “What?”

“On the dark side,” I said.

She looked again. “Oh…” she said. There were faint lights sprinkled across the darkness; hard to see, but definitely there. “Could it be volcanism?” asked Ling. Maybe Soror wasnt so perfect after all.

“Computer,” I said, “spectral analysis of the light sources on the planets dark side.”

“Predominantly incandescent lighting, color temperature 5600 kelvin.”

I exhaled and looked at Ling. They werent volcanoes. They were cities.

Soror, the world wed spent twelve centuries traveling to, the world wed intended to colonize, the world that had been dead silent when examined by radio telescopes, was already inhabited.

The Pioneer Spirit was a colonization ship; it wasnt intended as a diplomatic vessel. When it had left Earth, it had seemed important to get at least some humans off the mother world. Two small-scale nuclear wars — Nuke I and Nuke II, as the media had dubbed them — had already been fought, one in southern Asia, the other in South America. It appeared to be only a matter of time before Nuke III, and that one might be the big one.

SETI had detected nothing from Tau Ceti, at least not by 2051. But Earth itself had only been broadcasting for a century and a half at that point; Tau Ceti might have had a thriving civilization then that hadnt yet started using radio. But now it was twelve hundred years later. Who knew how advanced the Tau Cetians might be?

I looked at Ling, then back at the screen. “What should we do?”

Ling tilted her head to one side. “Im not sure. On the one hand, Id love to meet them, whoever they are. But…”

“But they might not want to meet us,” I said. “They might think were invaders, and—”

“And weve got forty-eight other colonists to think about,” said Ling. “For all we know, were the last surviving humans.”

I frowned. “Well, thats easy enough to determine. Computer, swing the radio telescope toward Sol system. See if you can pick anything up that might be artificial.”

“Just a sec,” said the female voice. A few moments later, a cacophony filled the room: static and snatches of voices and bits of music and sequences of tones, overlapping and jumbled, fading in and out.

I heard what sounded like English — although strangely inflected — and maybe Arabic and Mandarin and…

“Were not the last survivors,” I said, smiling. “Theres still life on Earth — or, at least, there was 11.9 years ago, when those signals started out.”
