Interstellar travel

“ You may be twenty years older than I am; you may have been one of the pioneers in space travel; you may still be a good man if you could forget that the whole world didn't plot that accident that left you with a bad leg—but you're still taking orders from me. We have some good men in this department, and you can either keep your mouth shut and work with us or you can get out. Interstellar drive isn't the only solution to space travel and the answer to the problem is going to come from this laboratory. ”

“ Yet, although the Solar System is many worlds with countless strange phenomena, still its scientific treasures are miniscule in comparison to those of the Galaxy. Interplanetary space travel is no longer a dream, but a reality? ”

“ The solar system was home to us, would always be home to us, but never, I knew, would either of us be able to break away from the fascination of the great fleet's interstellar patrol, the flashing from sun to sun, the long silent hours in cosmic night and stellar glare. ”

“ Later science, piling wonder upon wonder, handling radiant energy, packing compressed air for long excursions into outer space, sends out some skyship on tremendous errands of interstellar search. Days, weeks, they flit, with speed incredible, our earth a speck, our moon invisible, our sun a star among the others now ”

“ And through occasional rifts in the crowded mass of ships could be glimpsed the interplanetary traffic of the lower levels, a swarm of swift little boats which darted ceaselessly back and forth on their comparatively short journeys, ferrying crowds of passengers to Jupiter and Venus and Earth, seeming like little toy-boats beside the mighty bulks of the great interstellar ships above them. ”

“ From all the suns about us, our space-chart showed, great masses of interstellar ships were also flashing inward into the galaxy, the first exodus of the galaxy's people from the outer suns and worlds, driven inward by the fear of these mighty invaders from the outer void who had already destroyed the galaxy's fleet, and were preparing now to grasp all our universe. ”

“ Because they had at one time or another visited each of the planets in their solar system and had exhausted their possibilities or found them barren, and because they were not equipped, even at the peak of their physical development, for intergalactic flight, there remained only one way to travel—in time. ”

“ The people of the dark star had entered the solar system quite unannounced, except that they had been seen in passing the orbit of Mars, for a ship had been out there in space, moving steadily out toward Neptune, and the great interstellar cruisers, flashing in across space, away from that frigid planet, had not seen the tiny wanderer. ”

“ The landing of the Third Interstellar Expedition on this Vegan world had been a part of a vast evolution, a march that, starting on earth so long ago that all history of it was forever lost, was now reaching out across the cosmos. ”

“ Somewhere, out there under the stars, there must be grand glittering cities and busy spaceports, roaring gateways to the planets. Somewhere, out there in the night, there must be men who had walked beside the Martian canals and pierced the shining cloud mantle of Venus—somewhere, perhaps, men who had visited the distant luring stars and returned. Surely, a civilization that had developed time travel could reach the stars! ”

“ We know that as soon as interplanetary travel is possible, expeditions from the earth will be ranging the length and breadth of the solar system searching out the thousands of wonders that are to be discovered. ”

“ At any rate I am alive, and my lifeboat, while somewhat damaged by an inept landing, is still sufficiently intact to serve as a shelter, and the survival kits are undamaged, which should make my stay here endurable if not pleasant ... and we are learning a great deal about our galaxy with the development of the interstellar drive—not the least of which is that authoritative opinion is mere opinion and far from authoritative.
This world on which I find myself is in every respect but one similar to Earth. There is no animate life—only plants. ”

“ It was the familiar maneuver of the Interstellar Patrol in reconnoitering a meteor-swarm, to hang above it and race at the same speed with it through space, but never yet had we essayed it on such a swarm as this one, moving as it was at an incredible speed for inanimate matter, and without any signs about it of the ether-current which we had thought was the reason for that speed. ”

“ If there were no interstellar ships at all in the area, it was likely that the planet below was an isolated planet. There were plenty of them in the galaxy; when the infraspace drive had combined with Terrestrial overcrowding to produce the great migration, many of the pioneers had simply found themselves a planet, settled themselves into a community, dismantled their ship, and forgotten about the rest of mankind. ”

“ If it were, then life would seem meaningless. Mankind would be a freak, a cosmic accident.
And now the Wanderer was on the first interstellar flight, hurtling through the dark spaces to Proxima Centauri. Moving silently, as if motionless, yet at a speed of 160,000 miles a second. And ahead loomed the great, gray planet, the only planet of the sun, growing larger, larger, each instant....
A gentle, murmuring hum filled the ship. The indicator lights on the control panel glowed like a swarm of pink eyes.
"Deceleration compensator adjusted for 12 G's, sir," reported Lieutenant Gunderson. ”

“ Its function was interstellar cohesion.
“ ‘Such was my theory.
“ 'The flashes, I discovered, were harmless so long as they were not touched. After a bit I learned that the wreaths of current were broken like the ring. By maneuvering, I brought the ship opposite the break in the outer nucleus. I would get a good view of what might be inside. If I saw a chance I would sail straight into the comet’s heart! ”

“ A ship might undertake a voyage to last a century. If a matter-transposer were a part of it, it could be supplied with fuel and air and foodstuffs on its voyage. Its crew could be relieved and exchanged whenever it was desired. And when it made a planet-fall a hundred years and more from home, why, home would still be just around the transposer. With matter-transposition an interstellar civilization could arise and thrive, even though limited to the speed of light for its ships. ”

“ In past ages, exploration was a lonely enterprise. But today, the miracles of space travel are matched by miracles of space communication; even across the vast lunar distance, television brings the moment of discovery into our homes, and makes all of us participants. ”

“ At the time of this chronicle the status of interstellar flight was very similar to that of intercontinental jet-plane flight in the nineteen-sixties. Starships were designed by humanity's best brains; carried every safety device those brains could devise. ”

“ If we grant that interplanetary travel will one day come and people will travel as blithely to Mars or Venus as we do now across our oceans, we can realize that the adventures encountered in such journey will be one of the most extraordinary kind. A wreck on an ocean liner for example means merely the taking to life boats, or the awaiting of rescue but a few hours away. But in empty space tens of millions of miles from the nearest world and possibly millions from any other ship, an interplanetary wreck would be replete with occurrences of the most amazing nature. ”

“ A being inhabiting such a comet, and having these interstellar journeys as the years of his existence, so that he could live through many of them, would have a wonderful insight into the economy of the stellar system. If his powers of conception as far exceeded ours as the range of his travels and the duration of his existence, he would be able to recognise the proportions of a large part of the stellar universe as clearly as we recognise the proportions of the solar system. ”

“ While living upon the earth, it discovers the stars and their satellites; it travels underground, finds the metals in their hidden depths and unlocks the secrets of geological ages. It can cross the abysses of interstellar space and discover the motion of inconceivably distant suns. ”

“ He wanted to see the entire sky, and though he was no stranger to space travel, this was his first trip since the transposition of personalities and he wanted to see it with new eyes. But as always, there was not a single stellar formation that he found familiar. ”

“ It is truly that, though it is also truly more than that; but to illustrate that luminiferous aspect of it, I will quote a paragraph from the lecture of Clerk Maxwell's to which I have already referred:—
"The vast interplanetary and interstellar regions will no longer be regarded as waste places in the universe, which the Creator has not seen fit to fill with the symbols of the manifold order of His kingdom. ”

“ No enterprise has so stirred human imagination as the reach of man toward the exploration of space. New worlds to explore. New distances to travel—3,680 million miles to Pluto, the outermost planet of our solar system, 8 years journey at 50,000 miles per hour when we attain such a capability. Innumerable problems ahead. New knowledge needed in almost every branch of science and technology from magneto fluid dynamics to cosmology, from materials to biology and psychology. ”

“ As our space-flier dropped slowly toward that mighty structure beneath my controlling hands, as it dropped toward the swarms of bright-lit aircraft that were moving to and fro over the great city, so familiar was the scene beneath to us four cosmic voyagers that almost did our great journey, our mighty flight out through the sun's planets through the countless leagues of space to great Neptune, and our grotesque and dream-like adventures upon Neptune and its moon, seem to us indeed no more than dreams. ”

“ We had passed outside the last frontier of the solar system and were now racing out into the mighty deeps of space with the speed of light on our mad journey to save a universe.

An hour after we had left the solar system Hal Kur and I still stood with Sarto Sen in the cruiser's conning-tower, staring out with him at the stupendous panorama of gathered stars that lay before us. The sun of our own system had dwindled to a far point of light behind us, by that time, one star among the millions that spangled the deep black heavens around us. ”

“ The Big Jump is more conventional ... the battle of a monopolist family to hold the secret of interstellar flight makes a lively melodrama, with a virtually compelling finale of alien life on a remote star. ”

“ Although neither of them was unacquainted with interstellar space, it presents a spectacle that never fails to awe even the most seasoned observer: and no human being had ever before viewed the wonders of space from such a coign of vantage. Thus the two fell silent and awed as they gazed out into the abysmal depths of the interstellar void. The darkness of Earthly night is ameliorated by light-rays scattered by the atmosphere: the stars twinkle and scintillate and their light is diffused, because of the same medium. ”

“ Nevertheless, thus clad, I trod interstellar space, exalted by the knowledge that I was bound on vast adventure, where, at the end, I would find all the cosmic formulae and have made clear to me the ultimate secret of the universe. In my hand I carried a long glass wand. It was borne in upon me that with the tip of this wand I must touch each star in passing. And I knew, in all absoluteness, that did I but miss one star I should be precipitated into some unplummeted abyss of unthinkable and eternal punishment and guilt. ”

“ Since the beginning of recorded time, the earth, together with the other planets and the sun, has been speeding through interstellar space at the rate of 300,000,000 miles a year, without meeting or passing a single star. A ray of light, travelling with a velocity so great as to be scarcely measurable within the diameter of the earth's orbit, takes years to reach even the nearest star, centuries to reach those more distant. ”

“ Thus once more we plunged into space—infinite space,—dark, airless ether, with the myriads of glittering stars far off on every side. Again we got upon a meteor ring, and swept on through space toward the mighty system of the Ringed World. The journey was long— days and weeks and months, by your earth-measurement of time, passed on this weary voyage. Still Saturn seemed little more than a great star in space, with its mighty rings and its eight moons slowly growing more and more distinct. ”

“ It had been built to meet every conceivable danger that might be encountered in interstellar exploration—but the danger had come to the solar system from the direction of Capella nine years after the departure of the Thunderbolt. ”

“ It is arguable that this spirit of exploration is indispensable to a vigorous society, and that any society that ceases to explore, to inquire, and to strive is only a few years from decline.
And so the historian may recall the early days of lunar exploration, the Apollo project, the landing of unmanned Viking spacecraft on Mars, and the encounters of Voyager spacecraft with Jupiter and Saturn as the first steps in a sustained program of space exploration—a program that is profoundly changing man’s perspective of himself, of the Earth, and of the larger cosmos beyond. ”

“ In other words, the fruition of life on the various planets of the millions of solar systems might be the product of a wandering group of astronautic Johnny Appleseeds who leave the grains of life behind them. "Space travel between galaxies has to be possible for this, but of course this needs to be only quite a rare event. In a time of about 3.3 billion years, the most advanced form of life occurring in a galaxy must be able to reach a neighboring one." ”
