“What about Takagishi? And des Jardins?” Wakefield asked.

“We will leave the icemobile where it is, along with a rover here at Beta. They are both easy to operate. We will still be in radio contact from the Newton.” Dr. Brown stared directly at Richard. “If this spacecraft is really on an Earth impact course,” he said dramatically, “our individual lives are no longer very important. The entire course of history is about to be changed.”

“But what if the navigation engineers are wrong? What if Rama has just happened to make a maneuver that momentarily intersects an Earth impact trajectory? It could be—”

“Extremely unlikely. You remember that group of short-burst maneuvers at the time of Borzov’s death? They changed the orientation of Rama’s orbit so that an Earth impact could be achieved with one long maneuver at exactly the right time. The engineers on Earth figured it out thirty-six hours ago. They radioed O’Toole before dawn this morning to expect the maneuver. I didn’t want to say anything while everyone was out looking for Takagishi.”

“That explains why everyone is so anxious for us to clear out of here!” Janos noted.

“Only partially,” Dr. Brown continued. “There is clearly a different feel­ing about Rama and the Ramans down on Earth. ISA management and the world leaders on the COG Executive Council are apparently convinced that Rama is implacably hostile.”

He stopped for several seconds, as if he were reassessing his own attitude.

“I think they are reacting emotionally myself, but I cannot persuade them differently. I personally see no evidence of hostility, only a disinterest in and disregard for a wildly inferior being. But the televised account of Wilson’s death has done its damage. The world’s populace cannot be herebeside us, cannot grasp the majesty of this place. they can only react viscerally to the horror—”

“If you don’t think the Ramans have hostile intentions,” Francesca inter­rupted, “then how do you explain this maneuver? It can’t be coincidence. They or it has decided for some reason to head for the Earth. No wonder the people down there are traumatized. Remember, the first Rama never ac­knowledged its visitors in any way. This is a dramatically different response. The Ramans are telling us they know—”

“Hold it. Hold it,” Richard said. “I think we’re jumping to conclusions a little too fast. We have twelve more minutes before we should start pushing the panic buttons.”

“All right, Cosmonaut Wakefield,” Francesca said, now remembering that she was a reporter and activating her video camera, “for the record, what do you think it will mean if this maneuver does culminate in a trajectory that impacts the Earth?”

When Richard finally spoke he was very serious. “People of the Earth,” he said dramatically, “if Rama has indeed changed its course to visit our planet, it is not necessarily a hostile act. There is nothing, I repeat nothing, that any of us have seen or heard that indicates the species that created this space vehicle wishes us any harm. Certainly Cosmonaut Wilson’s death was dis­turbing, but it was probably an isolated response from a specific set of robots rather than a part of a sinister plan.

“I see this magnificent spacecraft as a single machine, almost organic in its complexity. It is extraordinarily intelligent and programmed for long-term survival. It is neither hostile nor friendly. It could easily have been designed to track any incoming satellites and compute where the visiting spacecraft must have originated. Rama’s orbit change to fly in the vicinity of the Earth might therefore be nothing more than its standard response to an encounter initiated by another spacefaring species. It may simply be coming to find out more about us.”

“Very good,” Janos Tabori said with a grin. “That was borderline philo­sophical.”

Wakefield laughed nervously.

“Cosmonaut Turgenyev,” Francesca said as she changed the direction of the camera, “do you agree with your colleague? Right after General Borzov died, you openly expressed some concern that perhaps some “higher force,” meaning the Ramans, might have had a hand in his death. What are your feelings now?”

The normally taciturn Soviet pilot stared directly into the camera with her sad eyes. “Da,” she said, “I think Cosmonaut Wakefield is a very brilliant engineer. But he has not answered the difficult questions. Why did Rama maneuver during General Borzov’s operation? Why did the biots cut Wilson to pieces? Where is Professor Takagishi?”

Irina Turgenyev paused a moment to control her emotions. “We will not find Nicole des Jardins. Rama may be only a machine, but we cosmonauts have already seen how dangerous it can be. If it is heading for the Earth, I fear for my family, my friends, for all humanity. There is no way to predict what it might do. And we would be powerless to stop it.”

Several minutes later Francesca Sabatini carried her automatic video equipment out beside the frozen sea for one final sequence. She carefully checked the time before switching on the camera at precisely fifteen seconds before the maneuver was expected to end. “The picture you are seeing is jumping up and down,” she said in her best journalistic voice, “because the ground underneath us here on Rama has been shaking continuously since this maneuver started forty-seven minutes ago. According to the navigation engineers, the maneuver will stop in the next few seconds if Rama has changed course to impact the Earth. Their calculations are, of course, based on assumptions about Rama’s intentions—”

Francesca stopped in midsentence and took a deep breath. “The ground is no longer shaking. The maneuver is over. Rama is now on an Earth impact trajectory.”

MAROONED

When Nicole awakened the first time she was groggy and had great difficulty holding any idea fixed in her mind. Her head hurt and she could feel sharp pains in her back and legs. She did not know what had happened to her. She was barely able to find her water flask and take a drink. I must have a concussion, she thought as she fell back asleep.

It was dark when Nicole woke up again. But her mind was no longer in a fog. She knew where she was. She remembered looking for Takagishi and sliding into the pit. Nicole also remembered calling for Francesca and the painful, terrible fall. She immediately took her communicator from the belt of her flight suit.

“Hello there, Newton team,” she said as she stood up slowly. “This is cosmonaut des Jardins checking in. I’ve been, well, indisposed might be a good word. I fell down into a hole and knocked myself out. Sabatini knows where I am…”

Nicole broke off her monologue and waited. There was no response from her receiver. She turned up the gain but only succeeded in picking up some strange static. It’s dark already, she thought, and it had only been light for two hours at most… Nicole knew that the periods of light inside Rama had been lasting about thirty hours. Had she been unconscious that long? Or had Rama thrown them another curveball? She looked at her wristwatch, which showed time elapsed since the start of the second sortie, and did a quick calculation. ! have been down here for thirty-two hours. Why has no­body come?

Nicole thought back to the last minutes before she fell. They had talked to Wakefield, and then she had dashed in to check the pits. Richard always did a navigation fix when they were in two-way lock and Francesca knew ex­actly…

Could something have happened to the entire crew? But if not, why had nobody discovered her? Nicole smiled to herself as she fought the onset of panic. Of course, she reasoned, they found me, but I was unconscious, so they decided… Another voice in her head told her that her thought pattern didn’t make sense. Under any circumstances, she would have been retrieved from the pit if they had found her.
