B-12's Moon Glow The Mirans knew their business though, for they started in on the IP station on Phobos. The Ultimate Weapon And one-fourth of the entire heavens, as seen from Phobos, will be filled with the glowing orb of Mars! Pharaoh's Broker Being the Very Remarkable Experiences in Another World of Isidor Werner He poked his beak at it, and with a great deal of trilling and clucking, he added Deimos and Phobos to Mars, and then sketched in the earth's moon! A Martian Odyssey The three stellene rings bumped lightly on the ten mile chunk of captured asteroidal rock and nickel-iron that was Phobos, Mars' nearer moon. The Planet Strappers We were banished to Phobos, dreary, lifeless moon of Mars. B-12's Moon Glow For two days the Mirans hung off Mars, solidifying their positions on Phobos and Deimos. The Ultimate Weapon "That last one is the one I saw before, that is my Phobos!" Pharaoh's Broker Being the Very Remarkable Experiences in Another World of Isidor Werner We knew that it was slightly smaller than Phobos, but its greater distance gave promise that it would better serve our purpose of temporary concealment. Edison's Conquest of Mars Phobos hadn't risen; Deimos, the farther moon, was too small to furnish appreciable light. The Planet Strappers All I know is this: we are people; we think and feel, and are happy and sad, and quite often we are bored stiff with this dreary moon of Phobos. B-12's Moon Glow The scouts raced back to Luna as the Miran settled heavily, and a trifle clumsily to Phobos. The Ultimate Weapon Phobos was also faintly visible, steering his backward course across the ruddy sky. Pharaoh's Broker Being the Very Remarkable Experiences in Another World of Isidor Werner The nearer of these moons, Phobos, is only 3,700 miles from the surface of Mars, and we watched it traveling around the planet three times in the course of every day. Edison's Conquest of Mars Phobos, larger and brighter, was not long risen, and it moved swiftly and smoothly across the sky, like the cold searchlight of some giant aircraft. Rebels of the Red Planet It is where I make the fluid which is called Moon Glow by the metal people of Phobos. B-12's Moon Glow An hour later the Miran returned, passed the still-lightless ship at a distance of five million miles, and settled to Phobos for the slight repairs needed. The Ultimate Weapon Small wonder that we could not make a landing, with Mars pulling us away sixty-five times harder than Phobos attracted us! Pharaoh's Broker Being the Very Remarkable Experiences in Another World of Isidor Werner No one bothered to tell me," continued Astro, "that I had to protect myself from the ultraviolet rays of the sun, since Phobos didn't have an atmosphere. Danger in Deep Space Phobos was setting for the first time that night when Dark reached the great hulk of Ultra Vires, manipulated one of the airlocks and entered its dark corridors. Rebels of the Red Planet By the way, friend, would you mind telling me what your real mission of your party is here on Phobos. B-12's Moon Glow The flight of five ships settled comfortably upon Phobos, while the three relieved of duty started back to Jupiter. The Ultimate Weapon Moreover, this must cause everything that is loose upon Phobos to fall upon Mars. Pharaoh's Broker Being the Very Remarkable Experiences in Another World of Isidor Werner The nakedness of the girls at the Phobos, the coarse jokes of the so-called comedians, the raucous, ribald laughter of the drunken patrons disgusted Hanlon, and he was glad when they left. Man of Many Minds Phobos was abroad in the east at sunset, so Dark waited a little longer, until the nearer moon plunged beneath the eastern horizon. Rebels of the Red Planet Why, that we are making a preliminary survey here on Phobos, of course, to determine whether or not it is worthwhile to send salvage for scrap. B-12's Moon Glow Phobos of course rotated with one face fixed irrevocably toward Mars itself, the other always to the cold of space. The Ultimate Weapon Phobos is very slow in overtaking us;" and he was just beginning to slacken speed still more, when he suddenly cried out,— "Here she is ahead of us now! Pharaoh's Broker Being the Very Remarkable Experiences in Another World of Isidor Werner I vote we drop on him first and let him carry us towards Phobos. A Honeymoon in Space Deimos was not in the sky this night, and Phobos' disappearance left it near pitch-dark. Rebels of the Red Planet It was an intricate little thing which could not, I am sure, have been duplicated on the entire moon of Phobos. B-12's Moon Glow Their power was being drained just a little bit better than twice as fast as they generated during the day—and since Phobos spun so swiftly across the sky. The Ultimate Weapon I asked, indicating the full disc of Phobos. Pharaoh's Broker Being the Very Remarkable Experiences in Another World of Isidor Werner Zaidie got her apparatus to work, and when she had taken her slides down to the dark-room, Redgrave turned the R. Force on very slightly and Phobos began to sink away beneath them. A Honeymoon in Space Almost as though released by the sunset, pale Phobos popped above the horizon and began to climb its eastward way. Rebels of the Red Planet It is said that your present survey is being made with the purpose of condemning all of Phobos, the dead and the living alike, to the blast furnaces and the metal shops of Earth. B-12's Moon Glow When Deenmor operated from Phobos' position, Mars Center was exposed to the deadly, constant drain. The Ultimate Weapon I led him hastily to the telescope, and explained to him that the smaller forward spot was caused by a moon like Phobos, and that the Earth was really a round ball, like the Sun. Pharaoh's Broker Being the Very Remarkable Experiences in Another World of Isidor Werner As they approached Phobos they saw that half the little disc was brilliantly lighted by the same rays of the sun which were glowing on the rapidly increasing crescent of Mars beneath them. A Honeymoon in Space The nearer of these moons, Phobos, is only 3,700 miles from the surface of Mars, and we watched it travelling around the planet three times in the course of every day. Edison's Conquest of Mars It is yours to decide, and you will decide that we are not worth bothering with here on Phobos. B-12's Moon Glow A day or two later, the bombs were coming one each second and a half, for more ships had joined in the work on Phobos. The Ultimate Weapon The larger of the two, Phobos, is believed to be about seven miles in diameter; the smaller, Deimos, only five or six miles. Other Worlds Their Nature, Possibilities and Habitability in the Light of the Latest Discoveries A very slight exertion of repulsive force was sufficient to detach the Astronef from the body of Phobos. A Honeymoon in Space We knew that it was slightly smaller than Phobos but its greater distance gave promise that it would better serve our purpose of temporary concealment. Edison's Conquest of Mars The satellite Phobos is indeed believed to be about to take this very plunge into his planet. The Birth-Time of the World and Other Scientific Essays One of the fleet of Phobos rose, and circled about the planet, and settled gracefully beside the station. The Ultimate Weapon One of these, called Deimos, is only six miles in diameter, the other, named Phobos, is only seven, and both are exceedingly close to the primary and in rapid revolution. Scientific American Supplement, No. 832, December 12, 1891 Phobos revolves from west to east almost along the plane of its primary's equator. A Honeymoon in Space Standing on the surface of this planet, my attention was easily attracted by the two frisky moons called Deimos and Phobos, at the small distance of 14,600 and 12,500 miles respectively. Life in a Thousand Worlds A satellite of the dimensions of Phobos—that is 36 miles in diameter—would hardly survive more than 30 to 60 years within seventy miles of Mars' surface. The Birth-Time of the World and Other Scientific Essays It was long gone, when the first atomic bombs and magnetic bombs dropped from Phobos reached the spot, and only hot rock and broken metal remained. The Ultimate Weapon It was a print in silver, and while we gazed in mute astonishment the sharp shadows changed their position as Phobos, racing through the zenith, changed the inclination of its incident beams. The Certainty of a Future Life in Mars On February 10 I had my first vision of Mars' two moons, known to our astronomers as Diemos and Phobos. The Planet Mars and Its Inhabitants, a psychic revelation But the other, Phobos, at first was a puzzle, owing to its incredible velocity being unsuspected. History of Astronomy Suppose we consider the case of a satellite approaching Mars which has a diameter double that of Phobos; a diameter still much less than that of the larger class of asteroids. The Birth-Time of the World and Other Scientific Essays Mars Center failed in fact the next time Phobos rode high over it. The Ultimate Weapon The landscape about us was wonderfully illuminated by the two satellites, Deimos and Phobos, which, as you well know, were made known to astronomers on the earth by Prof. Asaph Hall in 1877. The Certainty of a Future Life in Mars As the radius of Phobos's circle was far shorter than that of the parabolic curve they were making, it began to draw away, and was rapidly left behind. A journey in other worlds A romance of the future A tract 100 miles in diameter and elevated 5,000 or 10,000 feet would seriously perturb the orbit of such a body as Phobos. The Birth-Time of the World and Other Scientific Essays If in a fluid or plastic state, Phobos, for instance, could not possibly exist near the planet's surface. The Birth-Time of the World and Other Scientific Essays Already they knew that a similar ship had appeared off Jupiter, and, after wiping out the Phobos and Mars stations with one bomb each, had cleared the Jovian Satellites with equal terrible efficiency. The Ultimate Weapon With the exception of Phobos the next smallest satellite known in the solar system is one of Saturn's—Hyperion; almost 800 miles in diameter. The Birth-Time of the World and Other Scientific Essays The inner one, Phobos, is considerably larger, having a diameter of about twenty miles. A journey in other worlds A romance of the future To fix our ideas on these points I take the case of the present satellite Phobos. The Birth-Time of the World and Other Scientific Essays |
