Unless one of you two has some experience in Mars-lander handling that you've been concealing from us."

Neither of them bothered to answer that. The radio hi the nose sputtered, then clanged for their attention. Crawford looked over at Lang, who made no move to go answer it He stood up and swarmed up the ladder to sit in the copilot's chair. He switched on the receiver.

"Commander Lang?"

"No, this is Crawford again. Commander Lang is . . . indisposed. She's busy with Lou, trying to do something."

"That's no use. The doctor says it's a miracle he's still breathing. If he wakes up at all, he won't be anything like you knew him. The telemetry shows nothing like the normal brain wave. Now I've got to talk to Commander Lang. Have her come up." The voice of Mission Commander Weinstein was accustomed to command, and about as emotional as a weather report"Sir, I'll ask her, but I don't think sh.e.l.l come. This is still her operation, you know." He didn't give Weinstein time to reply to that Weinstein had been trapped by his own seniority into commanding the Edgar Rice Burroughs, the orbital ship that got them to Mars and had been intended to get them back.

Command of the Podkayne, the disposable lander that would make the lion's share of the headlines, had gone to Lang. There was little friendship between the two, especially when Weinstein fell to brooding about the very real financial benefits Lang stood to reap by being the first woman on Mars, rather than the lowly mission commander. He saw himself as another Michael Collins.

Crawford called down to Lang, who raised her head enough to mumble something.

"What'd she say?"

"She said take a message." McKillian had been crawling up the ladder as she said this. Now she reached him and said in a lower voice, "Matt, she's pretty broken up. You'd better take over for now."

"Right, I know." He turned back to the radio, and McKillian listened over his shoulder as Weinstein briefed them on the situation as he saw it. It pretty much jibed with Crawford's estimation, except at one crucial point. He signed off and they joined the other survivors.

He looked around at the faces of the others and decided it wasn't the time to speak of rescue possibilities. He didn't relish being a leader. He was hoping Lang would recover soon and take the burden from him. In the meantime he had to get them started on something. He touched McKillian gently on the shoulder and motioned her to the lock.

"Let's go get them buried," he said. She squeezed her eyes shut tight, forcing out tears, then nodded.

It wasn't a pretty job. Halfway through it, Song came down the ladder with the body of Lou Prager.

"Let's go over what we've learned. First, now that Lou's dead there's very little chance of ever lifting off. That is, unless Mary thinks she can absorb everything she needs to know about piloting the Podkayne from those printouts Weinstein sent down. How about it, Mary?"

Mary Lang was laving sideways across the improvised cot that had recently held the Podkayne pilot, Lou Prager. Her head was nodding listlessly against the aluminum hull plate behind her, her chin was on her chest. Her eyes were half-open.

Song had given her a sedative from the dead doctor's supplies on the advice of the medic aboard the E.R.B, It had enabled her to stop fighting so hard against the screaming panic she wanted to unleash. It hadn't improved her disposition. She had quit; she wasn't going to do anything for anybody.

When the blowout started, Lang had snapped on her helmet quickly. Then she had struggled against the blizzard and the undulating dome bottom, heading for the roofless framework where the other members of the expedition were sleeping. The blowout was over in ten seconds, and she then had the problem of coping with, the collapsing roof, which promptly buried her in folds of clear plastic. It was far too much like one of those nightmares of running knee-deep in quicksand. She had to fight for every meter, but she made it.

She made it in time to see her shipmates of the last six months gasping soundlessly and spouting blood from all over their faces as they fought to get into their pressure suits. It was a hopeless task to choose which two or three to save in the time she had. She might have done better but for the freakish nature of her struggle to reach them; she was in shock and half believed it was only a nightmare. So she grabbed the nearest, who happened to be Doctor Ralston. He had nearly finished donning his suit; so she slapped his helmet on him and moved to the next one. It was Luther Nakamura, and he was not moving.

Worse, he was only half suited. Pragmatically she should have left him and moved on to save the ones who still had a chance. She knew it now, but didn't like it any better than she had liked it then.

While she was stuffing Nakamura into his suit, Crawford arrived. He had walked over the folds of plastic until he reached the dormitory, then sliced through it with his laser normally used to vaporize rock samples.

And he had had time to think about the problem of whom to save. He went straight to Lou Prager and finished suiting him up. But it was already too late. He didn't know if it would have made any difference if Mary Lang had tried to save him first.

Now she lay on the bunk, her feet sprawled carelessly in front of her. She slowly shook her head back and forth."You sure?" Crawford prodded her, hoping to get a rise, a show of temper, anything.

"I'm sure," she mumbled. "You people know how long they trained Lou to fly this thing? And he almost cracked it up as it was. I ... ah, nuts. It isn't possible."

"I refuse to accept that as a final answer," he said. "But in the meantime we should explore the possibilities if what Mary says is true."

Ralston laughed. It wasn't a bitter laugh; he sounded genuinely amused. Crawford plowed on.

"Here's what we know for sure. The E.R.B. is useless to us. Oh, they'll help us out with plenty of advice, maybe more than we want, but any rescue is out of the question."

"We know that," McKillian said. She was tired and sick from the sight of the faces of her dead friends. "What's the use of all this talk?"

"Wait a moment," Song broke in. "Why can't they ... I mean they have plenty of time, don't they?

They have to leave in six months, as I understand it, because of the orbital elements, but in that time..."

"Don't you know anything about s.p.a.ceships?" McKillian shouted. Song went on, unperturbed.

"I do know enough to know the Edgar is not equipped for an atmosphere entry. My idea was, not to bring down the whole ship but only what's aboard the ship that we need. Which is a pilot. Might that be possible?"

Crawford ran his hands through his hair, wondering what to say. That possibility had been discussed, and was being studied. But it had to be cla.s.sed as extremely remote.

"You're right," he said. "What we need is a pilot, and that pilot is Commander Weinstein. Which presents problems legally, if nothing else. He's the captain of a ship and should not leave it. That's what kept him on the Edgar in the first place. But he did have a lot of training on the lander simulator back when he was so sure he'd be picked for the ground team. You know Winey, always the instinct to be the one-man show. So if he thought he could do it, he'd be down here in a minute to bail us out and grab the publicity. I understand they're trying to work out a heat-shield parachute system from one of the drop capsules that were supposed to ferry down supplies to us during the stay here. But it's very risky. You don't modify an aerodynamic design lightly, not one that's supposed to hit the atmosphere at ten thousand-plus kilometers. So I think we can rule that out They'll keep working on it, but when it's done, Winey won't step into the d.a.m.n dung. He wants to be a hero, but he wants to live to enjoy it, too."

There had been a brief lifting of spirits among Song, Ralston, and McKillian at the thought of a possible rescue. The more they thought about it, the less happy they looked. They all seemed to agree with Crawford's a.s.sessment.

"So we'll put that one in the Fairy G.o.dmother file and forget about it. If it happens, fine. But we'd better plan on the a.s.sumption that it won't. As you may know, the E.R.B.-Podkayne are the only ships in existence that can reach Mars and land on it. One other pair is in the congressional funding stage. Winey talked to Earth and thinks there'll be a speedup in the preliminary paperwork and the thing'll start building in a year. The launch was scheduled for five years from now, but it might get as much as a year boost. It's a rescue mission now, easier to sell. But the design will need modification, if only to include five more seats to bring us all back. You can bet on there being more modifications when we send in our report on the blowout. So we'd better add another six months to the schedule."

McKillian had had enough. "Matt, what the h.e.l.l are you talking about? Rescue mission? d.a.m.n it, you know as well as I that if they find us here, we'll be long dead. We'll probably be dead hi another year."

"That's where you're wrong. We'll survive."

"How?"

"I don't have the faintest idea." He looked her straight in the eye as he said this. She almost didn't bother to answer, but curiosity got the best of her.

"Is this just a morale session? Thanks, but I don't need it. I'd rather face the situation as it is. Or do you really have something?"

"Both. I don't have anything concrete except to say that well survive the same way humans have always survived: by staying warm, by eating, by drinking. To that list we have to add 'by breathing.'

That's a hard one, but other than that we're no different than any other group of survivors in a tough spot.I don't know what we'll have to do, specifically, but I know we'll find the answers."

"Or die trying," Song said.

"Or die trying." He grinned at her. She at least had grasped the essence of the situation. Whether survival was possible or not, it was necessary to maintain the illusion that it was. Otherwise, you might as well cut your throat. You might as well not even be born, because life is an inevitably fatal struggle to survive.

"What about air?" McKillian asked, still unconvinced.

"I don't know," he told her cheerfully. "It's a tough problem, isn't it?"

"What about water?"

"Well, down in that valley there's a layer of permafrost about twenty meters down."

She laughed. "Wonderful. So that's what you want us to do? Dig down there and warm the ice with our pink little hands? It won't work, I tell you."

Crawford waited until she had run through a long list of reasons why they were doomed. Most of them made a great deal of sense. When she was through, he spoke softly.

"Lucy, listen to yourself."

"I'm just-"

"You're arguing on the side of death. Do you want to die? Are you so determined that you won't listen to someone who says you can live?"

She was quiet for a long time, then shuffled her feet awkwardly. She glanced at him, then at Song and Ralston. They were waiting, and she had to blush and smile slowly at them.

"You're right. What do we do first?"

"Just what we were doing. Taking stock of our situation. We need to make a list of what's available to us. We'll write it down on paper, but I can give you a general rundown." He counted off the points on his fingers.

"One, we have food for twenty people for three months. That conies to about a year for the five of us. With rationing, maybe a year and a half. That's a.s.suming all the supply capsules reach us all right. In addition, the Edgar is going to clean the pantry to the bone and give us everything they can possibly spare and send it to us in the three spare capsules. That might come to two years or even three.

"Two, we have enough water to last us forever if the recyclers keep going. That'll be a problem, because our reactor will run out of power in two years. We'll need another power source, and maybe another water source.

"The oxygen problem is about the same. Two years at the outside.

We'll have to find a way to conserve it a lot more than we're doing. Offhand, I don't know how.

Song, do you have any ideas?"

She looked thoughtful, which produced two vertical punctuation marks between her slanted eyes.

"Possibly a culture of plants from the Edgar. If we could rig some way to grow plants in Martian sunlight and not have them killed by the ultraviolet. . . ."

McKillian looked horrified, as any good ecologist would.

"What about contamination?" she asked. "What do you think that sterilization was for before we landed? Do you want to louse up the entire ecological balance of Mars? No one would ever be sure if samples in the future were real Martian plants or mutated Earth stock."

"What ecological balance?" Song shot back. "You know as well as I do that this trip has been nearly a zero. A few anaerobic bacteria, a patch of lichen, both barely distinguishable from Earth forms-"

"That's just what I mean. You import Earth forms now, and we'll never tell the difference."

"But it could be done, right? With the proper shielding so the plants won't be wiped out before they ever sprout, we could have a hydroponics plant functioning-"

"Oh, yes, it could be done. I can see three or four dodges right now. But you're not addressing the main question, which is-"

"Hold it," Crawford said. "I just wanted to know if you had any ideas." He was secretly pleased at the argument; it got them both thinking along the right lines, moved them from the deadly apathy they must guard against."I think this discussion has served its purpose, which was to convince everyone here that survival is possible." He glanced uneasily at Lang, still nodding, her eyes gla.s.sy as she saw her teammates die before her eyes.

"I just want to point out that instead of an expedition, we are now a colony. Not in the usual sense of planning to stay here forever, but all our planning will have to be geared to that fiction. What we're faced with is not a simple matter of stretching supplies until rescue comes. Stopgap measures are not likely to do us much good. The answers that will save us are the long-term ones, the sort of answers a colony would be looking for. About two years from now we're going to have to be in a position to survive with some sort of lifestyle that could support us forever. We'll have to fit into this environment where we can and adapt it to us where we can. For that, we're better oft than most of the colonists of the past, at least for the short term. We have a large supply of everything a colony needs: food, water, tools, raw materials, energy, brains, and women. Without these things, no colony has much of a chance. All we lack is a regular resupply from the home country, but a really good group of colonists can get along without that. What do you say? Are you all with me?"

Something had caused Mary Lang's eyes to look up. It was a reflex by now, a survival reflex conditioned by a lifetime of fighting her way to the top. It took root in her again and pulled her erect on the bed, then to her feet. She fought off the effects of the drug and stood there, eyes bleary but aware.

"What makes you think that women are a natural resource, Craw-ford?" she said, slowly and deliberately.

"Why, what I meant was that without the morale uplift provided by members of the opposite s.e.x, a colony will lack the push needed to make it."

"That's what you meant, all right. And you meant women, available to the real colonists as a reason to live. I've heard it before. That's a male-oriented way to look at it, Crawford." She was regaining her stature as they watched, seeming to grow until she dominated the group with the intangible power that marks a leader. She took a deep breath and came fully awake for the first time that day.

"We'll stop that sort of thinking right now. I'm tile mission commander. I appreciate you taking over while I was . . . how did you say it? Indisposed. But you should pay more attention to the social aspects of our situation. If anyone is a commodity here, it's you and Ralston, by virtue of your scarcity. There will be some th.o.r.n.y questions to resolve there, but for the meantime we will function as a unit, under my command. We'll do all we can to minimize social compet.i.tion among the women for the men. That's the way it must be. Clear?"

She was answered by quiet a.s.sent and nods of the head. She did not acknowledge it but plowed right on.

"I wondered from the start why you were along, Crawford." She was pacing slowly back and forth in the crowded s.p.a.ce. The others got out of her way almost without thinking, except for Ralston who still huddled under his blanket. "A historian? Sure, it's a fine idea, but pretty impractical. I have to admit that I've been thinking of you as a luxury, and about as useful as the nipples on a man's chest. But I was wrong. All the NASA people were wrong. The Astronaut Corps fought like crazy to keep you off this trip. Time enough for that on later flights. We were blinded by our loyalty to the test-pilot philosophy of s.p.a.ce flight. We wanted as few scientists as possible and as many astronauts as we could manage. We don't like to think of ourselves as ferry-boat pilots. I think we demonstrated during Apollo that we could handle science jobs as well as anyone. We saw you as a kind of insult, a slap in the face by the scientists in Houston to show us how low our stock has fallen."

"If I might be able to-"

"Shut up. But we were wrong. I read in your resume that you were quite a student of survival. What's your honest a.s.sessment of our chances?"

Crawford shrugged, uneasy at the question. He didn't know if it was the right time to even postulate that they might fail.

"Tell me the truth."

"Pretty slim. Mostly the air problem. The people I've read about never sank so low that they had to worry about where their next breath was coming from.""Have you ever heard of Apollo 13?"

He smiled at her. "Special circ.u.mstances. Short-term problems."

"You're right, of course. And in the only two other real s.p.a.ce emergencies since that time, all hands were lost." She turned and scowled at each of them in turn.

"But we're -not going to lose." She dared any of them to disagree, and no one was about to. She relaxed and resumed her stroll around the room. She turned to Crawford again.

"I can see I'll be drawing on your knowledge a lot in the years to come. What do you see as the next order of business?"

Crawford relaxed. The awful burden of responsibility, which he had never wanted, was gone. He was content to follow her lead.

"To tell you the truth, I was wondering what to say next. We have to make a thorough inventory. I guess we should start on that."

"That's fine, but there is an even more important order of business. We have to go out to the dome and find out what the h.e.l.l caused the blowout. The d.a.m.n thing should not have blown; it's the first of its type to do so. And from the bottom. But it did blow, and we should know why, or we're ignoring a fact about Mars that might still kill us. Let's do that first. Ralston, can you walk?"

When he nodded, she sealed her helmet and started into the lock. She turned and looked speculatively at Crawford.

"I swear, man, if you had touched me with a cattle prod you couldn't have got a bigger rise out of me than you did with what you said a few minutes ago. Do I dare ask?"

Crawford was not about to answer. He said, with a perfectly straight face, "Me? Maybe you should just a.s.sume I'm a chauvinist."

"We'll see, won't we?"

"What is that stuff?"

Song Sue Lee was on her knees, examining one of the hundreds of short, stiff spikes extruding from the ground. She tried to scratch her head but was frustrated by her helmet.

"It looks like plastic. But I have a strong feeling it's the higher life-form Lucy and I were looking for yesterday."

"And you're telling me those little spikes are what poked holes in the dome bottom? I'm not buying that."

Song straightened up, moving stiffly. They had all worked hard to empty out the collapsed dome and peel back the whole, bulky mess to reveal the ground it had covered. She was tired and stepped out of character for a moment to snap at Mary Lang.

"I didn't tell you that. We pulled the dome back and found spikes. It was your inference that they poked holes in the bottom."
