The title is a play on words, one meaning "the force which pulls" & the other being "extremely serious or important". It was serialized in Astounding Science Fiction, 4–7/53. Its 1st cloth publication was in '54. It was 1st published in paper in '58. Along with the novel itself, many editions (& most recent editions) of the book also include Whirligig World, an essay on creating the planet Mesklin that was published in the 6/53 Astounding. He published two sequels, a '70 novel called Star Light & a '73 short story called Lecture Demonstration. Mission of Gravity was nominated for a Retro Hugo Award for '54.For a profit & adventure Barlennan would sail thousands of miles across uncharted waters, into regions where gravity played strange tricks. He'd dare the perils of strange tribes & stranger creatures--even dicker with those aliens from beyond the skies, though the concept of another world was unknown to the inhabitants of the planet of Mesklin. But in spite of the incredible technology of the strangers & without regard for their enormous size, Barlennan had the notion of turning the deal to an unsuspected advantage for himself--a considerable enterprise for a being very much resembling a 15" caterpillar!

    But what his neighbors must never know is that, inside his unchanging house, he meets with a host of unimaginable friends from the farthest stars.More than a hundred years before, an alien named Ulysses had recruited Enoch as the keeper of Earth's only galactic transfer station. Now, as Enoch studies the progress of Earth and tends the tanks where the aliens appear, the charts he made indicate his world is doomed to destruction. His alien friends can only offer help that seems worse than the dreaded disaster. Then he discovers the horror that lies across the galaxy...

    It is a lonely job, and a thankless one for the most part. Until something goes wrong. Until a ship is in distress. In the 23rd century, this job has moved into outer space. A network of beacons allows ships to travel across the Milky Way at many times the speed of light. These beacons are built to be robust. They never break down. They never fail. At least, they aren't supposed to.

    Mia Havero's Ship is a small closed society. It tests its children by casting them out to live or die in a month of Trial in the hostile wilds of a colony world. Mia Havero's Trial is fast approaching and in the meantime she must learn not only the skills that will keep her alive but the deeper courage to face herself and her world. Published originally in 1968, Alexei Panshin's Nebula Award-winning classic has lost none of its relevance, with its keen exploration of societal stagnation and the resilience of youth.

    An alien civilization on the brink of destruction captures the signal and plans to invade Earth. Meanwhile, on Earth, different camps start forming, planning to either welcome the superior beings and help them take over a world seen as corrupt, or to fight against the invasion. The result is a science fiction masterpiece of enormous scope and vision.

    In the aftermath, a curious tradition was invented-something to cheer up everyone who was left and bring the shattered worlds together in the spirit of peace, unity, and understanding.Once every cycle, the civilizations gather for the Metagalactic Grand Prix - part gladiatorial contest, part beauty pageant, part concert extravaganza, and part continuation of the wars of the past. Instead of competing in orbital combat, the powerful species that survived face off in a competition of song, dance, or whatever can be physically performed in an intergalactic talent show. The stakes are high for this new game, and everyone is forced to compete.This year, though, humankind has discovered the enormous universe. And while they expected to discover a grand drama of diplomacy, gunships, wormholes, and stoic councils of aliens, they have instead found glitter, lipstick and electric guitars. Mankind will not get to fight for its destiny - they must sing.A one-hit-wonder band of human musicians, dancers and roadies from London - Decibel Jones and the Absolute Zeroes - have been chosen to represent Earth on the greatest stage in the galaxy. And the fate of their species lies in their ability to rock.

    It was an epoch of glory and success, of disaster and despair...1881: A generation after the South won the Civil War, America writhed once more in the bloody throes of battle. Furious over the annexation of key Mexican territory, the United States declared total war against the Confederate States of America once again. But this was a new kind of war, fought on a lawless frontier where the blue and gray battled not only each other but the Apache, the outlaw, the French, and the English. As Confederate General Stonewall Jackson again demonstrated his military expertise, the North struggled to find a leader who could prove his equal. In the Second War Between the States, the times, the stakes, and the battle lines had changed--and so would history...

    Every lunar walker since Apollo 11 has noticed it: a burnt-metal scent that reminds them of war. Caden Dechert, the chief of the U.S. mining operation on the edge of the Sea of Serenity, thinks the smell is just a trick of the mind—a reminder of his harrowing days as a Marine in the war-torn Middle East back on Earth.It’s 2072, and lunar helium-3 mining is powering the fusion reactors that are bringing Earth back from environmental disaster. But competing for the richest prize in the history of the world has destroyed the oldest rule in space: Safety for All. When a bomb kills one of Dechert’s diggers on Mare Serenitatis, the haunted veteran goes on the hunt to expose the culprit before more blood is spilled.But as Dechert races to solve the first murder in the history of the Moon, he gets caught in the crosshairs of two global powers spoiling for a fight. Reluctant to be the match that lights this powder-keg, Dechert knows his life and those of his crew are meaningless to the politicians. Even worse, he knows the killer is still out there, hunting.In his desperate attempts to save his crew and prevent the catastrophe he sees coming, the former Marine uncovers a dangerous conspiracy that, with one spark, can ignite a full lunar war, wipe out his team . . . and perhaps plunge the Earth back into darkness.

    She had no memory of how she died. That was also new; before, when she had awakened as a new clone, her first memory was of how she died.Maria's vat was in the front of six vats, each one holding the clone of a crew member of the starship Dormire, each clone waiting for its previous incarnation to die so it could awaken. And Maria wasn't the only one to die recently...

    The ensuing climate cataclysm will soon render the earth inhospitable for humanity, as the last such meteorite did for the dinosaurs. This looming threat calls for a radically accelerated effort to colonize space, and requires a much larger share of humanity to take part in the process.Elma York’s experience as a WASP pilot and mathematician earns her a place in the International Aerospace Coalition’s attempts to put man on the moon, as a calculator. But with so many skilled and experienced women pilots and scientists involved with the program, it doesn’t take long before Elma begins to wonder why they can’t go into space, too.Elma’s drive to become the first Lady Astronaut is so strong that even the most dearly held conventions of society may not stand a chance against her.

    Yes, that seemed normal enough---but what was this talk about "death trauma"?Thus was Thomas Blaine introduced to the year 2110, where science had discovered the technique of transferring a man's consciousness from one body to another. Where a man's mind could be snatched from the past, when his body was at the point of death, and brought forward into a "host body" in this fantastic future world. But that was only a small part of it. For the future had proved the reality of life after death, and discovered worlds beyond or simultaneous with our own---worlds where, through scientific techniques, a man could live again, in another body, when he died here. And in the process, the reality of ghosts, poltergeists, and zombies was also established. What did it all mean? How had this discovery of what they called the "hereafter" shaped the world of 2110? Thomas Blaine found himself living in a future where the discoveries and techniques imagined by people of his time, while having come about, were completely overwhelmed by discoveries no one had ever dreamed of.

    Donaldson returns with this exciting and long-awaited new series that takes us into a stunningly imagined future to tell a timeless story of adventure and the implacable conflict of good and evil within each of us.Angus Thermopyle was an ore pirate and a murderer; even the most disreputable asteroid pilots of Delta Sector stayed locked out of his way.  Those who didn't ended up in the lockup--or dead.  But when Thermopyle arrived at Mallory's Bar & Sleep with a gorgeous woman by his side the regulars had to take notice.  Her name was Morn Hyland, and she had been a police officer--until she met up with Thermopyle.But one person in Mallory's Bar wasn't intimidated.  Nick Succorso had his own reputation as a bold pirate and he had a sleek frigate fitted for deep space.  Everyone knew that Thermopyle and Succorso were on a collision course.  What nobody expected was how quickly it would be over--or how devastating victory would be.  It was common enough example of rivalry and revenge--or so everyone thought.  The REAL story was something entirely different.In The Real Story, Stephen R. Donaldson takes us to a remarkably detailed world of faster-than-light travel, politics, betrayal, and a shadowy presence just outside our view to tell the fiercest, most profound story he has ever written.

    Rails must be freshly laid ahead of the city & carefully removed in its wake. Rivers & mountains present nearly insurmountable challenges to the ingenuity of the city's engineers. But if the city does not move, it will fall farther & farther behind the optimum & into the crushing gravitational field that has transformed life on Earth. The only alternative to progress is death. The secret directorate that governs the city makes sure that its inhabitants know nothing of this. Raised in common in creches, nurtured on synthetic food, prevented above all from venturing outside the closed circuit of the city, they're carefully sheltered from the dire necessities that have come to define human existence. Yet the city is in crisis. People are growing restive. The population is dwindling. The rulers know that, for all their efforts, slowly but surely the city is slipping ever farther behind the optimum. Helward Mann is a member of the city's elite. Better than anyone, he knows how tenuous is the city's continued existence. But the world he's about to discover is infinitely stranger than the strange world he believes he knows so well.

    John Harrison’s dangerously illuminating new novel, three quantum outlaws face a universe of their own creation, a universe where you make up the rules as you go along and break them just as fast, where there’s only one thing more mysterious than darkness.In contemporary London, Michael Kearney is a serial killer on the run from the entity that drives him to kill. He is seeking escape in a future that doesn’t yet exist—a quantum world that he and his physicist partner hope to access through a breach of time and space itself.

But the “inhuman” K-ship captain has gone rogue, pirating the galaxy while playing cat and mouse with the authorities who made her what she is. In this future, Ed Chianese, a drifter and adventurer, has ridden dynaflow ships, run old alien mazes, surfed stellar envelopes. He “went deep”—and lived to tell about it. Once crazy for life, he’s now just a twink on New Venusport, addicted to the bizarre alternate realities found in the tanks—and in debt to all the wrong people.Haunting them all through this maze of menace and mystery is the shadowy presence of the Shrander—and three enigmatic clues left on the barren surface of an asteroid under an ocean of light known as the Kefahuchi Tract: a deserted spaceship, a pair of bone dice, and a human skeleton.

    Most days, she's got other things on her mind. Like hiding her identity among the hundreds of alien species roaming the corridors of Watertower Station. Or making sure her adoptive mother doesn't casually eviscerate one of their neighbors. Again.And most days, she can almost accept that she'll never know the truth--that she'll never know why humanity was deemed too dangerous to exist. Or whether she really is--impossibly--the lone survivor of a species destroyed a millennium ago. That is, until an encounter with a bounty hunter and a miles-long kinetic projectile leaves her life and her perspective shattered.Thrown into the universe at the helm of a stolen ship--with the dubious assistance of a rebellious spacesuit, an android death enthusiast on his sixtieth lifetime, and a ball of fluff with an IQ in the thousands--Sarya begins to uncover an impossible truth. What if humanity's death and her own existence are simply two moves in a demented cosmic game, one played out by vast alien intellects? Stranger still, what if these mad gods are offering Sarya a seat at their table--and a second chance for humanity?The Last Human is a sneakily brilliant, gleefully oddball space-opera debut--a masterful play on perspective, intelligence, and free will, wrapped in a rollicking journey through a strange and crowded galaxy.
