By August 1968, the American space program was in danger of failing in its two most important objectives: to land a man on the moon by President Kennedy's end-of-decade deadline and to triumph over the Soviets in space. With its back against the wall, NASA made an almost unimaginable leap: It would scrap its usual methodical approach and risk everything on a sudden launch, sending the first men in history to the moon - in just four months.

Humans call them Monument-Makers. An unknown race, they left stunning alien statues scattered on distant planets throughout the galaxy, encoded with strange inscriptions that defy translation. Searching for clues about the Monument-Makers, teams of 23rd century linguists, historians, engineers and archaeologists have been excavating the enigmatic alien ruins on a number of planets, uncovering strange, massive false cities made of solid rock. But their time is running out.

Much has been written about Neil Armstrong, America's modern hero and history's most famous space traveler. Yet, shy of fame and never one to steal the spotlight, Armstrong was always reluctant to discuss his personal side of events. Here for the first time is the definitive story of Neil's life of flight he shared for five decades with a trusted friend - Jay Barbree.

In August 1968 NASA made a bold decision: In just 16 weeks, the United States would launch humankind's first flight to the moon. Only the year before, three astronauts had burned to death in their spacecraft, and since then the Apollo program had suffered one setback after another. Meanwhile, the Russians were winning the space race, the Cold War was getting hotter by the month, and President Kennedy's promise to put a man on the moon by the end of the decade seemed sure to be broken.

The wickedest, most wonderful science fiction story ever created in our - or any - time. Anything can begin at a party in California - and everything does in this bold masterwork by a grand master of science fiction. When four supremely sensual and unspeakably cerebral humans - two male, two female - find themselves under attack from aliens who want their awesome quantum breakthrough, they take to the skies - and zoom into the cosmos on a rocket roller-coaster ride of adventure, danger, ecstasy, and peril.

In the year 2031, a robot probe detects traces of biological activity on Enceladus, one of Saturn's moons. This sensational discovery shows that there is indeed evidence of extraterrestrial life. Fifteen years later, a hurriedly built spacecraft sets out on the long journey to the ringed planet and its moon. The international crew is not just facing a difficult twenty-seven months: if the spacecraft manages to make it to Enceladus without incident it must use a drillship to penetrate the kilometer-thick sheet of ice that entombs the moon.

The Mote In God's Eye is their acknowledged masterpiece, an epic novel of mankind's first encounter with alien life that transcends the genre. No lesser an authority than Robert A. Heinlein called it "possibly the finest science fiction novel I have ever read".

This is the story of a unique American hero who came of age as an astronaut during the few dramatic years when man reached the moon. Cernan's career spanned the entire Apollo program, from the tragic fire that killed three of his comrades on Apollo 1, through the moment when he left man's last footprint on the moon as commander of Apollo 17.

A catastrophic event renders the earth a ticking time bomb. In a feverish race against the inevitable, nations around the globe band together to devise an ambitious plan to ensure the survival of humanity far beyond our atmosphere, in outer space.

In 1978, the first group of space shuttle astronauts was introduced to the world - 29 men and six women who would carry NASA through the most tumultuous years of the space shuttle program. Among them was USAF Colonel Mike Mullane, who, in his memoir Riding Rockets, strips the heroic veneer from the astronaut corps and paints them as they are - human.

The date is 1966 of the Galactic Era, almost three thousand years from now, and the Republic, created by the human race - but not yet dominated by it - finds itself in an all-out war. They stand against the Teroni Federation, an alliance of races that resent Man's growing military and economic power. The main battles are taking place in the Spiral Arm and toward the Core. But far out on the Rim, the Theodore Roosevelt is one of three ships charged with protecting the Phoenix Cluster.

Roger Torraway watched in horror as the monster lurched, toppled over and died. Project Man Plus had gone suddenly and drastically wrong. The race to colonize Mars was too important, too costly, and America was already too committed, for plans to be scrapped. They would have to make a new Martian. And Roger Torraway was it, candidate for the endless surgery, operation after painful operation, that would enable him to survive on that faraway planet.

Cities were crushed by the falling spacecraft, but one ship didn't crash. It remained intact and disgorged hordes of alien soldiers determined to fight to the death. The abandoned vessels also contained a wealth of advanced technology. Led by David Levinson, the greatest minds of our world developed deadly new hybrid weapons. Bases were built on the moon, Mars, and beyond. A new generation of defenders had to be trained, for the invaders would return.

‘It didn’t matter that they were now three miles beyond their target site, that communications were dropping out and that they were running low on fuel. All that mattered to Neil as he searched for a safe spot to land was that boulders littered the surface below. “Thirty seconds,” called mission control. In truth, the flight controllers were now no more than spectators, just like everybody else. No more needed to be said. It was down to Armstrong

Hybrid fighters merging human and alien technology. Massive cannon emplacements on the moon and Mars. A planetary defense force with the finest military personnel ever trained. For two decades we've known the enemy would return. The nations of Earth have collaborated on a unified defense program designed to defend the planet.
