He didn’t know if he should take that as a good sign or a bad one. It didn’t much matter. The mission was in shambles. It had fallen apart, failed to achieve every one of its objectives.

No, that was wrong. This wasn’t some anonymous “mistakes were made” scenario, not even some third-party “the captain is responsible for a ship” rhetoric.

He had done this. He had caused this. The failures, the losses, they were due to his mistakes. His plans, his strategies, his errors in judgment had cost them. Half the crew vaporized in an antimatter-driven fireball. The shuttle, vaporized. All but nine of their space suits, vaporized.

Were they operational?

Technically, yes. Was this survivable? That was a whole different question, and the one foremost in his mind. His primary obligation was to get the remainder of his crew home alive. He wasn’t sure that was possible; they might already be dead men walking.

He felt most guilty over the death of Duan Me. He’d disliked the political officer, not as a human being, but for what she did. He’d idly wished her ill.

Now a completely illogical part of his mind felt culpable in her death. He knew it was ridiculous; the universe did not bend to his will to determine who lived and died. She would have been no less dead if he had loved her like his mother. He knew that. He still couldn’t throw off that extra load of unreasonable guilt piled on top of the immense load of entirely justifiable guilt he carried.

Somehow he had to push all that aside and manage the welfare of the rest of his crew. The explosion hadn’t killed them, not directly, anyway. The ship’s surge protectors and electromagnetic pulse firewalls were there to protect it from a major solar event. No one had tested it as a defense against a nearby nuclear detonation, but it had worked well enough. All the major circuits and power subsystems were intact. Some lesser stuff had been fried. The ship was functional—what was left of it after the aerobraking maneuvers, the only catastrophe that wasn’t entirely his fault.

But they’d been counting on what was left of the ship to operate at a hundred percent of capability. That was no longer possible. Some of the damaged subsystems were certainly not repairable. How many, they didn’t know yet. They might not have an exact count of how many they’d lost until after the repair attempts failed, but there was no doubt that the number was considerably larger than zero.

Those repairs would be slowed for weeks or months, by the deaths of so many people. The loss of all the scientists, tragic as it was in human terms, did not directly affect the running of the ship. The loss of pilots, maintenance technicians, and engineers did.

Zhang had been prudent enough not to send over anyone absolutely vital to ship’s operations, but even so they were now operating with barely better than a skeleton crew. They’d hoped that they might repair one of the badly damaged external tanks with the carbon fiber and printer donated by the Americans. Now they no longer had the personnel to do that. The ship’s status would not be clear for some time, but it was somewhere between “bad” and “disastrous.”

That wasn’t even considering what the aliens might do. Hundreds of the autonomous spacecraft, the worker ants, had positioned themselves between the Celestial Odyssey and the alien constellation. The ship’s instruments had picked up very faint positron signatures. Regardless of whatever the aliens used them for, each of those ants was a flying nuclear weapon.

Zhang ordered the Celestial Odyssey to back off, very slowly, very cautiously. The maneuvering engines drove the slightest of orbital changes, increasing the gap between them and the aliens by less than a meter a second. It was nothing that should alarm them or trigger an attack, but it had been enough to substantially increase the distance between the ship and the ants since the explosion.

The flying bombs hadn’t moved forward. They’d stayed where they were, letting the Celestial Odyssey pull away. That was good news… unless the aliens were waiting for the ship to be safely far from the facilities before they vaporized it with a score of antimatter detonations. Who knew?

Meanwhile, the military and political gamers in Beijing were trying to work through the various scenarios confronting the ship.

With the total loss of the external tanks, the Celestial Odyssey’s delta-vee capabilities were much reduced. With some effort, they could whip up enough to get them a Hohmann transfer to Earth, with a small safety margin for the unexpected. Of which, so far, there’d been no shortage. Just one problem. It would take six years to get back. That wasn’t survivable.

Beijing thought differently, perhaps? Zhang didn’t know for sure.

With more than half the crew gone, the survivors might be able to stretch supplies out considerably longer than otherwise. The Beijing experts politely requested Zhang confirm the situation. Sighing, he set his quartermaster about taking inventory, following orders but knowing that Beijing was thinking about it the wrong way.

The limits weren’t food, air, and water. It was about turning what was to have been a three-year mission into a much longer one. The ship’s designers had considered an extended mission of five or more years, but they hadn’t considered a ship so badly damaged and incapacitated.

Engineering and Environmental thought they could keep them all alive for two and a half more years. Sufficient repairs to the life-support and engineering systems might let the engineers nurse them along for three.

Zhang wasn’t taking any bets on that. So far, the gods he didn’t believe in had not looked favorably upon this mission. So, a four-year mission? Probably. Five? Probably not. Six? Forget it. The vessel that passed by Earth six years from now, seven and a half years after it departed, would be crewed by corpses.

They considered throwing additional velocity at the problem. If the Celestial Odyssey used up all its reaction-mass reserves, they could trim a year off the transit time. Meaning that they’d die two years out from Earth instead of three. Zhang asked Navigation and Beijing to consider more desperate scenarios.

There was one. It almost worked. If they topped off the remaining tanks and burned all their reaction mass leaving Saturn, they could pile on enough extra velocity to drop the transit time to Earth orbit to under two and a half years. That was survivable. The catch was that once they got there they’d have no delta-vee left for matching Earth’s orbit and another ship would have to rescue the crew.

There were a couple of problems with that. First, they’d pass Earth’s orbit moving twelve km/s faster than the earth. Second, the timing was imperfect. Earth would be tens of millions of kilometers away. The only ships that existed that were capable of those kind of delta-vees and long-distance travel were the Celestial Odyssey and the Nixon.

Could the engineers build a rescue ship fast enough to do that? Perhaps: desperation was an excellent motivator.

Zhang had the unpleasant feeling that Beijing wouldn’t mind at all if the Celestial Odyssey and its remaining crew simply disappeared. They’d achieved nothing of value, which made them a political and scientific embarrassment. He did not, of course, voice that opinion to his superiors. He was considerably more candid with his first officer.

“Mr. Cui, what’s your take on Beijing’s plan for getting us home?”

“Well, sir, I think it could work.” Cui Zhuo didn’t say more. She looked acutely uncomfortable under the placid gaze of her commander.
