Les Johnson - Going Interstellar

Aloud, he said, “Observations show that we are entering a region of very low hydrogen density.”

Immediately the avatar replied, “This will necessitate reducing power consumption.”

“Power consumption may be reduced below the levels needed to keep the crew alive,” Ignatiev said.

For half a heartbeat the AI avatar said nothing. Then, “That is a possibility.”

“If we change course to remain within the region where hydrogen density is adequate to maintain all the ship’s systems,” Ignatiev continued slowly, carefully, “none of the crew’s lives would be endangered.”

“Not so, Alexander Alexandrovich,” the avatar replied.

“Not so?”

“The immediate threat of reduced power availability might be averted by changing course, but once the ship has left its preplanned trajectory toward Gliese 581, how would you navigate toward our destination? Course correction data will take more than twelve years to reach us from Earth. The ship will be wandering through a wilderness, far from its destination. The crew will eventually die of starvation.”

“We could navigate ourselves,” said Ignatiev. “We wouldn’t need course correction data from mission control.”

The avatar’s image actually shook its head. “No member of the crew is an accredited astrogator.”

“I can do it!” Nikki cried. “I monitor the navigation program.”

With a hint of a smile, the avatar said gently, “Monitoring the astrogation program does not equip you to plot course changes.”

Before Nikki or anyone else could object, Ignatiev asked coolly, “So what do you recommend?”

Again the AI system hesitated before answering, almost a full second. It must be searching every byte of data in its memory, Ignatiev thought.

At last the avatar responded. “While this ship passes through the region of low fuel density the animate crew should enter cryonic suspension.”

“Cryosleep?” Gregorian demanded. “For how long?”

“As long as necessary. The cryonics units can be powered by the ship’s backup fuel cells—”

The redhaired engineer said, “Why don’t we use the fuel cells to run the ship?”

Ignatiev shook his head. The kid knows better, he’s just grasping at straws.

Sure enough, the AI avatar replied patiently, “The fuel cells would power the ship for a week or less, depending on internal power consumption.”

Crestfallen, the engineer said, “Yeah. Right.”

“Cryosleep is the indicated technique for passing through this emergency,” said the AI system.

Ignatiev asked, “If the fuel cells are used solely for maintaining the cryosleep units’ refrigeration, how long could they last?”

“Two months,” replied the avatar. “That includes maintaining the cryosleep units already in use by the cargo.”

“Understood,” said Ignatiev. “And if this region of low fuel density extends for more than two months?”

Without hesitation, the AI avatar answered, “Power to the cryosleep units will be lost.”

“And the people in those units?”

“They will die,” said the avatar, without a flicker of human emotion.

Gregorian said, “Then we’d better hope that the bubble doesn’t last for more than two months.”

Ignatiev saw the others nodding, up and down the conference table. They looked genuinely frightened, but they didn’t know what else could be done.

He thought he did.

The meeting broke up with most of the crew members muttering to one another about sleeping through the emergency.

“Too bad they don’t have capsules big enough for the two of us,” Gregorian said brashly to Nikki. He was trying to show a valor he doesn’t truly feel, Ignatiev thought. They don’t like the idea of crawling into those capsules and closing the lids over their faces. It scares them. Too much like coffins.

With Gregorian at her side, Nikki approached him as he headed for the conference room’s door. Looking troubled, fearful, she asked, “How long …do you have any idea?”

“Probably not more than two months,” he said, with a certainty he did not actually feel. “Maybe even a little less.”

Gregorian grasped Nikki’s slim arm. “We’ll take capsules next to each other. I’ll dream of you all the time we’re asleep.”

Nikki smiled up at him.

But Ignatiev knew better. In cryosleep you didn’t dream. The cold seeped into the brain’s neurons and denatured the chemicals that hold memories. Cryonic sleepers awoke without memories, many of them forgot how to speak, how to walk, even how to control their bladders and bowels. It was necessary to download a person’s brain patterns into a computer before entering cryosleep, and then restore the memories digitally once the sleeper was awakened.

The AI system is going to do that for us? Ignatiev scoffed at the idea. That was one of the reasons why the mission required keeping a number of the crew awake during the long flight: to handle the uploading of the memories of the two hundred men and women cryosleeping through the journey once they were awakened at Gliese 581.

Ignatiev left the conference room and headed toward his quarters. There was much to do: he didn’t entirely trust the AI system’s judgment. Despite its sophistication, it was still a computer program, limited to the data and instructions fed into it.

So? he asked himself. Aren’t you limited to the data and instructions fed into your brain? Aren’t we all?

“Dr. Ignatiev.”

Turning, he saw Nikki hurrying up the passageway toward him. For once she was alone, without Gregorian clutching her.

He made a smile for her. It took an effort.

Nikki said softly, “I want to thank you.”

“Thank me?”

“Vartan told me that he confided in you. That you made him understand …”

Ignatiev shook his head. “He was blind.”

“And you helped him to see.”

Feeling helpless, stupid, he replied, “It was nothing.”

“No,” Nikki said. “It was everything. He’s asked me to marry him.”

“People of your generation still marry?”

“Some of us still believe in a lifetime commitment,” she said.

A lifetime of two centuries? Ignatiev wondered. That’s some commitment.

Almost shyly, her eyes lowered, Nikki said, “We’d like you to be at our wedding. Would you be Vartan’s best man?”

Thunderstruck. “Me? But you …I mean, he …”

Smiling, she explained, “He’s too frightened of you to ask. It took all his courage for him to ask you about me.”

And Ignatiev suddenly understood. I must look like an old ogre to him. A tyrant. An intolerant ancient dragon.

“Tell him to ask me himself,” he said gently.

“You won’t refuse him?”

Almost smiling, Ignatiev answered, “No, of course not.”

Nikki beamed at him. “Thank you!”

And she turned and raced off down the passageway, leaving Ignatiev standing alone, wondering at the working of the human mind.

Once he got back to his own quarters, and still feeling slightly stunned at his own softheartedness, Ignatiev called for the AI system.

“How may I help you, Alexander Alexandrovich?” The image looked like Sonya once again. More than ever, Ignatiev thought.

“How will the sleepers’ brain scans be uploaded into them once they are awakened?” he asked.

“The ship’s automated systems will perform that task,” said the seemingly imperturbable avatar.

“No,” said Ignatiev. “Those systems were never meant to operate completely autonomously.”

“The uploading program is capable of autonomous operation.”

“It requires human oversight,” he insisted. “Check the mission protocols.”
