When Kell and his team return to Earth many years after their departure, they find that their world has changed almost beyond recognition. Not only has a second wave of greenhouse flooding caused sea levels to rise, but society has been changed by the consequences of the climate shift. Few people want to face Jordan Kell's news. He must convince Earth's new rulers that the human race is in danger of extinction unless it acts to forestall the death wave coming from the galaxy's heart.

Half-Navajo geologist Jamie Waterman has been selected for the ground team of the first manned expedition to our mysterious neighbor planet. Joining an international team of astronauts and scientists, he endures the rigors of training, the dangers of traveling an incredible distance in space, the challenges of an alien landscape, and the personal and political conflicts that arise when the team must face the most shocking discovery of all.

Seven years after the indomitable Doug Stavenger has realized his cherished dream of establishing a colony on the inhospitable lunar surface, Moonbase is a thriving community, a marvel of scientific achievement created and supported by nanotechnology: virus-sized machines that can build, cure, and destroy. But nanotechnology has been declared illegal by the home planet’s leaders, and a powerful despot is determined to lay claim to Stavenger’s peaceful city - or obliterate it, if necessary.

The surface of Venus is the most hellish place in the solar system, its ground hot enough to melt aluminum, its air pressure high enough to crush spacecraft landers like tin cans, its atmosphere a choking mix of poisonous gases. This is where the frail young Van Humphries must go—or die trying.

Earth is an old planet, and her teeming masses are running out of resources - and time. It is up to men such as Jeff Holman to discover a haven for Earth’s millions. Altair VI is one such planet, and Holman is determined to transform this world into one where the human race can survive. Star probes long ago informed Earth that Altair VI had a flourishing ecology with one very tough beast at the top of the food chain, one that will have to be dealt with before the human colony ships arrive. The beast is not only tough, it is as smart as a man. Holman is faced with a soul-wrenching decision - for to make Altair VI habitable for humans, all native life must die.

Keith Stoner lay frozen in an alien spacecraft for 15 long years. During that time he came to be something more than just an astronaut, or just a man. Stoner became partly alien himself, merged with an alien intelligence embodied in the nanotechnology that lived inside his body.

A 21st century U.S. aerospace company has developed the first permanent human settlement on the Moon, made possible by major scientific breakthroughs, particularly in the practical use of nanotechnology. But conflict within the company's founding family and growing protests against the technology from radical environmentalists and religious fundamentalists on Earth put Moonbase in danger of closure

Island One is a celestial utopia, and David Adams is its most perfect creation - a man with a brain as advanced as any computer and a body free of human frailties. But David is a prisoner - a captive of the colony that created him - destined to spend the days of his life in an island-sized cylinder that circles a doomed and desperate home planet. Thousands of miles below him, a world trembles; its people cringe in terror and despair in anticipation of an impending apocalypse. And fate has cast one extraordinary human in the role of savior.

Six years after the first manned Martian expedition, a second has been announced, this one motivated purely by its profitable potential. Half-Navajo geologist Jamie Waterman, a veteran of the first mission, feels his conflicted soul beckoning him back to the eerie, unforgiving planet. As commander of the new exploratory team, he will have to contend with a bitter and destructive rivalry, a disturbing new emotional attraction, and deadly, incomprehensible "accidents" that appear to be sabotage.

Dan Randolph never plays by the rules. A hell-raising maverick with no patience for fools, he is admired by his friends, feared by his enemies, and desired by the world's loveliest women. Acting as a 21st privateer, Randolph broke the political strangle-hold on space exploration, and became one of the world's richest men in the bargain.

In the future as Bova here imagines it, Earth is an ecological nightmare, and humanity may well go the way of the dinosaurs. But overhead orbits salvation. A vast metallic island in space, the Trikon station conducts genetic research too risky to be done on earth - research that could save the planet.

Jamie Waterman has made an important discovery on Mars. A cliff dwelling reveals the fact that an intelligent race lived on the red planet 65 million years ago, only to be driven into extinction by the crash of a giant meteor. But now the exploration of Mars is itself under threat of extinction, as the ultraconservative New Morality movement gains control of the U.S. government and cuts off all funding for the Mars program.

Stoner knew. The fiery object hurtling toward the Earth was an alien spacecraft. But the world might never know. He was trapped in an iron cordon of secrecy, for the discovery had shattered the world power balance, setting off a brutal struggle for supremacy that raged from the sacred halls of the Vatican to the corridors of the Kremlin and the Pentagon. The forces of fear and treachery would use any weapon at their command, from mind war to sabotage, to keep the world in darkness.

After more than a century of exploring the stars, Keith Stoner returns to Earth to find that the world he has come back to does not match the one he left.

Most nations have been taken over by ultraconservative religion-based governments, such as the New Morality in the United States. With population ballooning and resources running out, Earth is heading for nuclear war.
