Star Trek: The Original Series: The Rings of Time

“It’s back to normal,” he realized. “Just like before.”

“That’s right,” the scientist confirmed. “What’s more, I’ve been running an analysis of the rings. They’ve also stabilized. The vast majority of the ring matter has already fallen back into its usual formations.”

“Just in the last day or so?” Fontana stared at the monitor. She voiced the thought they were probably all thinking. “Was it the probe? Did it do something?”

“Possibly. Probably.” O’Herlihy scratched his beard. “There were those energy pulses right before you ran into difficulty, Shaun. As nearly as I can tell, the pulses were directed at the planet’s north pole, right into the heart of the vortex.”

Kirk pondered the scientist’s report. “What kind of energy, Doctor?”

“I’m not sure,” O’Herlihy admitted. “Possibly a stream of charged particles or directed plasma waves. Like a laser, almost.”

Or a phaser? Kirk wondered. Actual phasers would not be developed by Earth science for at least two centuries. Had the probe fired some variety of phaser at Saturn? Spock had not detected any defensive systems aboard the probe, but perhaps its phaser banks operated on different principles and were not recognized by the Enterprise’s sensors. Or maybe the beams were simply a previously unknown type of directed energy. In either case, they would be beyond O’Herlihy’s experience.

“So, the beams rebooted the hexagon somehow?” Fontana speculated, apparently more interested in their function than their nature. “Which stabilized the rings? That’s fantastic!”

But not unheard of, Kirk thought. He recalled the alien hieroglyphics on the probe and that obelisk back on Miramanee’s world. Once activated, the obelisk had projected a powerful deflector beam that had kept the planet from being struck by an oncoming asteroid. Was it possible that the probe had been designed to serve a similar purpose, fixing Saturn’s deteriorating rings? Or, more likely, resetting some other mechanism hidden somewhere deep within the mysterious hexagon?

“You may be on to something,” he told Fontana. “Perhaps the probe was here to repair Saturn’s rings.”

“And it left once it completed its mission?” Marcus seized on the idea, visibly fascinated. “But who sent the probe? And what interest would they have in maintaining Saturn’s rings?”

Good questions, Kirk thought. He wished he could tell O’Herlihy and Fontana more about the Preservers, not that there was much to tell. The ancient aliens were a mystery even in his own time. Had they anticipated humanity colonizing this solar system in the future and wanted to keep Saturn and its moons stabilized for Earth’s benefit? Or did they have another motive for fixing the ringed giant? Perhaps they simply wanted to preserve one of the sector’s natural wonders for conservation or aesthetic reasons. It would be funny, he mused, if the Preservers ultimately turned out to be some sort of cosmic park service.

“Shaun,” O’Herlihy asked him, “you were out there when those pulses fired. What did you see before the probe shocked you?”

You mean, what did Christopher see, Kirk thought, before I set up shop in his body. In truth, his last memory before finding himself in orbit was of touching the probe in the Enterprise’s transporter room. He hadn’t seen the pulses O’Herlihy was talking about.

“To be honest, it’s all kind of a blur,” he said. “Sorry.”

Marcus sighed. He sounded disappointed but not too surprised. “I was afraid of that. A little traumatic short- term-memory loss was to be expected, I suppose.”

“Is that serious?” Fontana asked, sounding worried.

“I doubt it,” the doctor said. “Patients who have been in accidents often have little recollection of the actual events. It’s probably nothing to be concerned about, provided the rest of Shaun’s memory is intact.” He looked Kirk over. “You do remember who I am, right?”

He made it sound like a joke, but Kirk thought he heard something more serious underneath.

“A nervous mother hen?” Kirk said with a grin. “Seriously, I admit I was a little shook up, but I’m feeling better every day. Stop treating me like a basket case, both of you. That’s an order.”

“Fair enough,” O’Herlihy said. “But you’ll tell me if you’re having problems, right?”

“You’ll be the first to know,” Kirk lied. He felt bad about deceiving the two astronauts. They deserved better. But he couldn’t risk changing history by revealing that he was actually a time traveler from the future. “But really, I just want to get back to work.”

Fontana looked relieved. “Okay, that’s the Shaun Christopher I’m used to.”

Kirk was glad to hear it. It occurred to him that if he had to impersonate a human of the twenty-first century, the commander of an exploratory space vessel was not a bad fit. He and Shaun probably had much in common, including similar instincts and training. Could be worse, he thought. I could be stuck in the body of an opera singer or a brain surgeon.

When in doubt, maybe he just needed to act like himself.

“On a lighter note,” O’Herlihy continued, “Mission Control also forwarded a new batch of personal e-mails from home. Not quite as good as a care package of homemade brownies, but they will have to do. There appear to be plenty of photos and videos to review at our so-called leisure.”

Interesting, Kirk thought. He looked forward to studying Christopher’s correspondence in private. He hoped they would tell him more about Shaun as a person.

Fontana flew down to the nearest computer terminal. “Duty be damned. I think we can take a few minutes out of our busy schedules to check out those e-mails right away.” She grinned at Kirk. “If that’s all right with you, Colonel.”

“Indulge yourself, Commander.” He figured that Christopher would say the same. “After what we’ve been through the past few days, I think we can all use a little taste of home.”

Too bad he wasn’t likely to have any messages from his real home.

Or century.

The crew members floated off to various terminals to enjoy their personal correspondence in relative privacy. Kirk was grateful that the other two astronauts were preoccupied with their own messages. That gave him a chance to skim Christopher’s messages without being watched too closely. He felt a twinge of guilt at reading Christopher’s e-mail but assumed that any assumption of privacy vanished when he took over the other man’s body. Besides, for all he knew, Shaun’s consciousness was residing at the back of his brain somewhere — if it hadn’t been erased or transferred elsewhere.

Was Shaun about to read these letters, too? Kirk hoped not. He knew from experience how hellish it could be to remain aware but helpless while another mind controlled your body.

I had enough of that on Platonius.

Shoving the unpleasant memory aside, he checked out the first missive.

“Hi, Dad!” the message began.

Kirk blinked in surprise. Shaun had children? Not too surprising, considering the astronaut’s age, he realized, but the filial salutation still hit him like a phaser on stun. He scanned the e-mails quickly, trying to get his bearings. Shaun seemed to have three kids, two in college and one much younger.

Color photos, attached to the letter, showed a Fourth of July picnic on a beach. The youngest boy, Rory, looked about eight years old.

The same age as David, Kirk thought.

Kirk had never met his own son. Carol preferred it that way. It dawned on Kirk that David — and his mother — would not be born for centuries. He found himself envying Shaun.

“Mom is taking us to Colonial Williamsburg,” Rory wrote. “She says hi.”

From the sound of things, Christopher’s kids were staying with their mom while he was in space. Kirk read the passage again. Just “hi” from the mom? He wondered what the story was with her and Shaun. Were they married, divorced, separated, or had they never lived together at all? Scrolling quickly through the e-mail, he didn’t find a separate note from the unnamed mother. The other letter appeared to be from Christopher’s sister — and his father.

Kirk chuckled to himself. He couldn’t help being amused to receive a personal message from Shaun’s dad,
