Calculations were rapidly made and the answer arrived at. The Rell prudently decided to remain where they were for the present.

Captain Leonard Brown, USAF, hunched over the instruments in the cramped control cabin which, being the only available s.p.a.ce in the s.h.i.+p, doubled as living quarters. A larger man would have found the arrangement impossible. Brown, being 5' 2" and weighing 105 pounds found it merely intolerable.

At the moment he was temporarily able to forget his discomfort, however. The many tiny dials and indicators told a story all their own to Brown's trained vision.

"Just another half hour," he whispered to himself. "Just thirty more minutes and I'll land. It may be just a dead planet but I'll still be the first."

There really wasn't a great deal for Brown to do. The s.h.i.+p was self-guided. The Air Force had trusted robot mechanisms more than human reactions.

Thus Brown's entire active contribution to the flight consisted in watching the dials (which recorded everything so even watching them was unnecessary) and in pressing the b.u.t.ton which would cause the s.h.i.+p to start its return journey.

Of course the scientists could have constructed another mechanism to press the b.u.t.ton and made it a completely robot s.h.i.+p. But despite their frailties and imperfections, human beings have certain advantages. Humans can talk. Machines may see and detect far more than their human creators but all they can do is record. They can neither interpret nor satisfactorily describe.

Brown was present not only to report a human's reactions to the first Mars flight; he was also along to see that which the machines might miss.

"We've never satisfactorily defined life," one of his instructors had told Brown shortly after he started the three grueling years of training which had been necessary, "so we can't very well build a foolproof machine for detecting it. That's why we've left room for 105 pounds of dead weight."

"Meaning me?"

"Meaning you."

"And I'm your foolproof machine for detecting life?"

"Let's say you're the closest we can come to it at present. We're banking everything on this first trip. It'll be at least eighteen months later before we can get a second s.h.i.+p into s.p.a.ce. So it's up to you to get everything you can ... some evidence of life, preferably animal, if possible. With public support it'll be a h.e.l.l of a lot easier squeezing appropriations out of Congress for the next s.h.i.+p and to get public support we need the biggest possible play in the newspapers. If anything is newsworthy on Mars it should be evidence of life ... even plant life."

So here he was, 105 pounds of concentrated knowledge and antic.i.p.ation, itching with the desire for action and also from more basic causes having to do with two months confinement in a small s.p.a.ce with a minimum of water.

"Life is most probable at the poles," the instructor had said. "You won't be able to stay long so we'll try to set you down right at the South Pole. You won't have room to bring back specimens. So keep your eyes open and absorb everything you see. Don't forget anything. What you bring back in your mind weighs nothing."

"It's just sitting there," the observing banks reported, "and the red flame has gone out."

"Is it safe now?" enquired the speculative bank.

"In what way?"

"Is it safe to go near that thing?"

"It's very huge," ventured the observing banks unasked. There was a stir of activity which encompa.s.sed practically all except the most simple units and which lasted for perhaps five minutes while the speculative bank's last question was processed.

Finally the interpretive bank reluctantly admitted, "We can't arrive at a positive answer. Too many unknown elements are present. We don't know for sure what caused the flame, when it might start again, or what, if anything, is inside."

"But you said it was a work of intelligence. Doesn't that mean Rell would be inside?"

"Not necessarily. They could have constructed the thing to operate itself."

It was just then that the observing banks reported, "It's opening."

The speculative bank quickly responded, "This is an emergency. We must be able to observe from close up. We'll have to approach it."

"The entire mind?" enquired the disciplinary corps.

The speculative bank hesitated. "No, we'll need to split up. One-fifth of us will go, the rest remain here. It's a short distance and we'll still be able to continue in complete contact."

Those who were to go were quickly sorted out and Raeillo/ee13 was quite thrilled to find he and Raellu//2 were included in the scouting party.

The group set off briskly toward their objective but had moved hardly one hundred yards when a vertigo seemed to overtake them. Raeillo/ee13 found himself swimming helplessly in a vortex of darkness and isolation, blanked off from not only the group-mind and his bank but also from Raellu//2. Frantically he grasped for some sort of stasis, but dependence on the group-mind was too ingrained and he was unable to stir his long-dormant powers of sight and education.

Then the isolation cleared to be replaced by a brief impression of chaos with perhaps a tinge of alienness. Another instant of vertigo followed and then everything was normal once more as the comfortable familiar mesh took hold.

"What was that?" Even the speculative bank sounded frightened.

"Sorry." The usually silent mes.h.i.+ng bank sounded abashed. "We weren't prepared for that. Some sort of thought wave is issuing from the opening and it disrupted the group mesh till we were able to take it into calculation and rebuild the mesh around it."

"Thought wave? Then there are Rell in that thing."

"Do not compute before the mesh is set," the interpretive bank cautioned. "The presence of Rell, while extremely probable, is not yet entirely certain."

Without waiting for a suggestion from elsewhere the disciplinary group ordered the entire mind forward.

Perhaps, in time of stress, dormant qualities tend to emerge, Raeillo/ee13 mused. Certainly everyone, himself included, appeared to be exercising speculative qualities. Not that specialization isn't a marvelous blessing, he hastily added, in case the disciplinary corps might be scanning his bank. But the disciplinary corps itself was as fascinated by the phenomenon ahead as Raeillo/ee13.

Emerging from the infinitely huge upright thing was a mobile being, also infinitely huge. Not that they were the same size. The mobile one was small enough to fit easily through the opening in the lower portion of the larger. But beyond a certain point words lose meaning and infinitely huge was the closest measurement the tiny Rell could find for either the upright pointed thing or the k.n.o.bby one which had emerged and was quickly identified as the source of the disrupting thought patterns.

Leonard Brown was enjoying himself thoroughly. The inside of a s.p.a.ce suit can scarcely be termed comfortable but at least you can move around in it and Brown was making the most of this sensation after two months cramped in his tiny cell. He was, in fact, comporting himself much as a three-year-old might have done after a similar release.

But before long he settled down to the serious business of observing and mentally recording everything in sight.

There were none of the mysterious 'ca.n.a.ls' in view, which was disappointing; one piece of glamour the publicity boys would necessarily forego until the next trip. The ice cap itself, if such it could be called, was almost equally disappointing. On Earth it would have been dismissed as a mere frost patch, if this section was typical. For a radius of many yards the ground was blasted bare by the action of the exhaust and nowhere in sight did there appear to be more than the flimsiest covering of white over the brown sandy soil.

"Not even lichens," muttered Brown in disgust.

But disgust cannot long stand against the magic of a fresh new planet and Brown continued his avid, though barren, search until hunger forced his return to the s.h.i.+p. He had been able to detect no life and was completely unaware of his close proximity to the planet's dominant species. It had been considered neither practical nor particularly desirable to build a microscope into the s.p.a.ce suit. Simplicity and the least possible weight had been the watchwords here as with everything designed to go aboard the s.h.i.+p.

In any case, a microscope would have done Brown little good in trying to detect the submicroscopic beings of the Rell.

The Rell, who had somewhat lost their fear of Brown, hastily retreated when they saw him returning to the still awesome s.h.i.+p.

"But are you sure he's completely self-powered?" the speculative bank queried. "No Rell inside him at all?"

"There are many Rell-like beings in various parts of him," replied the interpretive bank. "Some help digest his food, others are predators, and still others their enemies. But most are too big and clumsy to have developed intelligence, and even the small ones appear completely mindless."

"But where do the thought waves come from? We all felt them."

"It's hard to accept but we are almost forced to conclude they are emanating from the mobile unit itself, or rather from the living part within the coc.o.o.n."

"You're positive they aren't the product of some of the Rell-beings inside?"

"Almost positive. The mesh insists not. In fact, it claims this is an un-Rell like type of intelligence, though that appears to be a contradiction in terms. The thought pattern is completely outside our experience. In fact, it is so alien we haven't broken it down yet to the meaning behind it."

"But if the Rell inside are too large to have developed intelligence, how could this gigantic monster in which they live have done so?"

"We cannot yet say. Remember, the theory that intelligence cannot develop in creatures above a certain size is unproven, even though never before challenged. We've watched other races die through failure to adapt to change so apparently it is true of Rell-like creatures on this world. But who can say about organisms on another world or of the unprecedented size of this one? Completely different physical laws may apply."

It was later that afternoon after the Rell had spent much time observing Brown while Brown was busy observing the landscape that the interpretive bank made the triumphant announcement, "We have it! We've broken the thought waves down to their meanings and know what he's thinking. What would you like to know first?"

"Check and see if there are any Rell inside the other thing or on his home world. They might have constructed him."

"Apparently there are none, or at least no intelligent Rell, on his world. We can't guide his mind but the memory bank recorded all the thoughts we've received and some time ago he was thinking of something he termed 'vermin'. Apparently these are sometimes Rell-like creatures, although far larger. He regards them as a great nuisance, but mindless. The big thing, by the way, he calls a 's.h.i.+p' and it is utterly lifeless. We needn't fear the flame until this creature leaves."

"What about him? What is he like?"

"That's the most exciting part! He thought of his bodily needs once and we glimpsed a concept dealing with his physical construction. It's incredible! His body is composed almost entirely of water ... there's enough water in him alone to prolong the life of the Rell many ages. Further, the air in his 's.h.i.+p' is heavily impregnated with moisture and he even has reserve supplies of water for his needs."

At this, not only Raeillo/ee13, but all except perhaps the most responsible units felt a s.h.i.+ver of primitive longing and perhaps even greed. Not for millennia had there been such a plent.i.tude of water so close!

"Then can't we appropriate at least part of it?" asked the speculative bank.

"Unfortunately both the 'man', as he calls himself, and his 's.h.i.+p' are sealed so tightly that we could not penetrate either. Worse yet, almost half his time here is already gone. We don't quite understand his purpose here. His thoughts seem to say he is searching for Rell for some unfathomable reason yet he seems to know nothing of the Rell and cannot even detect us."

It was the next day when the time was almost all gone that the two big discoveries were made. During a routine check, the mesh came across a thought of the man's return and a visualization of his home world. It was so startling that the interpretive bank was recalled from its effort to try to devise a means through the s.p.a.cesuit and set at the new problem.

A hasty check of the man's subconscious thoughts revealed the big news. "Do you know," the interpretive bank announced, "not only does this being's home world have a moist atmosphere like that in his s.h.i.+p but two thirds of the surface of his world is liquid water!"

Even the speculative bank was silent for a full two seconds after this news. Then a hasty impulse was sent to the disciplinary corps and the entire mind called into action. An extreme emergency upon which the fate of the race hinged called for the utmost effort by even the humblest members of the group.

The Rell worked diligently and many blind alleys were explored, but it was not for some time that anyone thought of enquiring of the not-too-bright feeding bank how they were managing to keep the mind operating at considerably more than normal power with no frost within feeding distance.

"We're taking moisture from the air," was the answer.

"Where is the moisture coming from?" the interpretive bank was asked.

The answer didn't take long. Rapid measurements supplied it. "Some of it is vaporized frost but that wouldn't be enough for our needs. The only other possibility is that moisture must be seeping away from either the man or his s.h.i.+p despite his sureness that they were both airtight and our own investigations which confirmed it."

They had maintained a cautious distance from the s.h.i.+p for the most part despite the interpretive bank's a.s.surance of no immediate danger. But now they swarmed over both it and the s.p.a.cesuit determined to detect the leak.

They found none.

And now the man was returning to his s.h.i.+p.

"This is the last time," the mesh warned. It was now or never.

For a second there was conflict over control of the circuits to the disciplinary corps which carried with it command of the organism during the emergency. The speculative bank customarily a.s.sumed this responsibility, but a slight schism had developed between it and the interpretive bank. The latter's greater age and skill came into play and victory was quickly won.

From the disciplinary corps came the order, "Stay close to the 'man'."

The interpretive bank explained, "He breathes the air so he'll have to get to it some way."

The defeated speculative bank maintained a sulky silence.

Thus it was that the entire mind of the Rell rode into the interior of the s.h.i.+p through the airlock while cl.u.s.tered around Brown.

The Rell had grasped that the man lived and traveled inside his s.h.i.+p and the necessity for it to be airtight. But so desperate were the two races' needs that the necessity for an airlock and the consequent slight seepage each time it was used had not occurred to even the interpretive bank.

Inside, many Rell, suddenly intoxicated by the heady moisture-laden air, commenced uniting with each other then splitting away, each such union resulting in another unit of Rell, naturally. The interpretive bank again seized control.

"Stop it! Stop it this instant!" it snapped. "Reproduction must be kept to the former minimum for now. That is a firm order."

Reluctantly the process was halted. The interpretive bank explained, "It would not take long for us to use up the entire supply of water if we indulged in uncontrolled reproduction. That might endanger the whole trip."

"What do we do now?" the speculative bank finally asked.

"There is no way of knowing positively whether the man uses this same atmosphere until he returns to his world or not. For our own safety it would seem best, since Rell-like creatures already inhabit him, that we join them. If any place is safe it will be his interior. And there is plenty of moisture within to sustain us. But we must be good parasites," the interpretive bank warned. "Remember, no undue reproduction no matter how many quarts of moisture seem to be going to waste inside this 'man'. He may need it himself and if he does not survive the s.h.i.+p might not complete its trip."

Brown was just emerging from his s.p.a.ce suit so the Rell chose his closest available body opening and flowed as a group into his mouth and nostrils.

"Ahchoo!" sneezed Brown, violently evicting half the Rell.

They re-entered a bit more cautiously in order not to irritate the sensitive membrane again.

"Dammit," said Brown, "don't tell me I've caught a cold clear out here on Mars. Hope I didn't pick up any Martian germs."

But he needn't have worried. By the time he reached Earth he was far less germ-ridden, even if considerably more itchy on the exterior, than when he'd left. The Rell were good at self defense and a surprising number of mindless but voracious creatures in Brown's interior had been eliminated.

Brown dreaded having to give the news he carried but he needn't have. He was a conquering hero.

So much fuss was made over the first flight to Mars that Congress promptly voted twice the appropriation for the second s.h.i.+p that the Air Force had requested, despite strong opposition from the Navy and headlines which read: NO LIFE ON MARS.

Actually, as it happened, the headlines were one hundred percent correct, but they neglected to mention, chiefly because the headline writers didn't know it, that there were now two races of intelligent life on Earth.

LIFE SENTENCE.
