“Extremely unlikely,” Richard commented. “The engineering is much too crude.”

“At any rate,” O’Toole said, opening his backpack for some tools to dis­connect the apparatus, “I’m not taking any chances.”

At the Newton end of the passageway, O’Toole, Wakefield, and des Jardins found the second bomb fitted with the same apparatus. The trio watched it punch out one code attempt — with the same result, a failure somewhere in the third decade — and then they disabled it as well. Afterward they opened up the seal and exited from Rama.

Nobody greeted them when they stepped inside the Newton military ship. General O’Toole assumed that both Admiral Heilmann and Yamanaka were asleep and went immediately to the bedrooms. He wanted to talk to Heilmann in private anyway. But the two men were not in their rooms. It did not take long to confirm, in fact, that the other two cosmonauts were nowhere in the comparatively small living and working area of the military ship.

A search of the supply area in the back of the ship was also futile. How­ever, the threesome did discover that one of the extravehicular activity (EVA) pods was missing. This discovery raised another perplexing set of questions. Where could Heilmann and Yamanaka have gone in the pod? And why had they violated the top-priority project policy that at least one crew member should always stay onboard the Newton?

The three cosmonauts were puzzled as they returned to the control center to discuss their possible courses of action. O’Toole was the first to raise the specter of foul play. “Do you think those octospiders, or even some of the biots, might have come onboard? After all, it’s not difficult to enter the Newton unless it’s in Self-Protection Mode.”

Nobody wanted to say what all three of them were thinking. If someone or something had captured or killed their two colleagues on the ship, then it might still be around and they might be in danger themselves…

“Why don’t we call the Earth and announce that we’re alive?” Richard said, breaking the silence.

“Great idea.” General O’Toole smiled. He moved over to the control center console and activated the panel. A standard system status display appeared on the large screen. “That’s strange,” the general commented. “According to this, we have no video link with the Earth presently. Only low-rate telemetry. Now, why would the data system configuration have been changed?”

He keyed in a simple set of commands to establish the normal multichan­nel high-rate link with the Earth. A swarm of error messages appeared on the monitor. “What the hell?” Richard exclaimed. “It looks as if the video system has died.” He turned to O’Toole. “This is your speciality, General, what do you make of all this?”

General O’Toole was very serious. “I don’t like it, Richard. I’ve only seen this many error messages one time before — during one of our early simula­tions when some nincompoop forgot to load the communications software. We must have a major software problem. The probability of that many hardware failures in such a short time span is essentially zero.”

Richard suggested that O’Toole subject the video communications soft­ware to its standard self-test. During the test, the diagnostic printout re­ported that the error buffers in the self-test algorithm had overflowed when the procedure was less than one percent complete. “So the vidcomm soft­ware is definitely the culprit,” Richard said, analyzing the data in the diag­nostic. He entered some commands. “It’s going to take a while to straighten it out—”

“Just a minute,” Nicole interrupted. “Shouldn’t we spend our time trying to make some sense out of all this new information before we start on any specific tasks?” The two men stopped their activity and waited for her to continue. “Heilmann, Yamanaka, and one pod are missing from this ship,” Nicole said, walking slowly around the control center, “and someone was trying to automatically activate the two nuclear bombs in the passageway. Meanwhile the vidcomm software, after functioning properly for hundreds of days — counting all the preflight simulations — has suddenly gone haywire. Do either of you have a coherent explanation for all this?”

There was a long silence. “General O’Toole’s suggestion of a hostile inva­sion of the Newton might work!” Richard offered. “Heilmann and Yamanaka might have fled to save themselves and the aliens could have purposely screwed up the software.”

Nicole was not convinced. “Nothing I have seen suggests that any aliens — or even any biots, for that matter — have been inside the Newton. Unless we see some evidence—”

“Maybe Heilmann and Yamanaka were trying to break the general’s code,” Wakefield invented, “and they were afraid—”

“Stop. Stop,” Nicole shouted suddenly. “Something’s happening to the screen.” The two men turned around just in time to see Admiral Otto Heilmann’s face materialize on the monitor.

“Hello, General O’Toole,” Heilmann said with a smile from the huge screen. “This videotape was triggered by your entering the Newton airlock. Cosmonaut Yamanaka and I prepared it just before we departed in one of the pods three hours before 1-9 days. We were ordered to evacuate less than an hour after you went inside to explore Rama. We delayed as long as we could but eventually had to follow our instructions.

“Your personal orders are simple and straightforward. You are to enter your activation code into the two weapons in the ferry passageway and the three remaining in the bay. You should depart in the final pod no more than eight hours thereafter. Don’t be concerned about the electronic devices in operation on the two bombs in the Raman shell. COG military headquarters ordered them put in place to test some new top secret decryption tech­niques. You will discover they can easily be disabled with pliers and!or wirecutters.

“An extra, emergency propulsion system has been added to the pod and its software has been programmed to guide you to a safe location, where you will rendezvous with an ISA tug. All you need to do is code in the exact time of your departure. However, I must stress that the new pod navigation algo­rithms are valid only if you leave the Newton before 1-6 days. After that time, I am told the guidance parameters become increasingly invalid and it will be almost impossible to rescue you.”

There was a short pause in Heilmann’s delivery and his voice took on an increased sense of urgency. “Don’t waste any more time, Michael. Activate the weapons and go directly to the pod. We have already supplied it with the food and other essentials that you will need… Good luck on your voyage home. We’ll see you back on Earth.”

HOBSON’S CHOICE

I’m certain that Heilmann and Yamanaka were being extremely cau­tious,” Richard Wakefield explained. “They probably left early so they could take extra supplies. And with these lightweight pods, each extra kilogram can be critical.”

How critical?” asked Nicole.

“Well — it could make all the difference between getting into a safe orbit around Earth — or shooting past it so quickly that we couldn’t be rescued.”

“Does that mean,” O’Toole inquired somberly, “that only one of us might be able to use the pod?”

Richard paused before answering. “I’m afraid that’s possible; it’s a func­tion of the time of departure. We’ll have to do some quick calculations to determine exactly. But personally I see no reason why we shouldn’t consider flying this entire spacecraft. I was trained as a backup pilot, after all. . We have only limited control authority, since the ship is so large, but if we jettison everything we don’t absolutely need, we may be able to do it Again, we’ll need to do the computations.”

Nicole’s assignments from General O’Toole and Richard were to check the supplies that had been placed in the pod, determine their adequacy, and then approximate both the mass and packaging volume required to support either two or three travelers. In addition Richard, still favoring flying back to Earth in the military ship, asked Nicole to go through the Newton supply manifest and estimate how much mass could be thrown overboard.
