Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

Earth has fallen under the influence of the Fermion Party, whose members believe humanity’s future lies in the metaverse, a simulated environment to which people can upload their consciousness to become immortal. As a simulant, one cannot get sick, grow old, or die. Human beings have no business risking their lives in the betaverse, where injury and illness can kill them. And those who wish to explore beyond the solar system blaspheme what the Fermions believe is the natural order.

Have you ever wondered what it would be like to find yourself strapped to a giant rocket that's about to go from zero to 17,500 miles per hour? Or to look back on Earth from outer space and see the surprisingly precise line between day and night? Or to stand in front of the Hubble Space Telescope, wondering if the emergency repair you're about to make will inadvertently ruin humankind's chance to unlock the universe's secrets? Mike Massimino has been there, and in Spaceman he puts you inside the suit.

The ice is coming. It was the last thing we expected, but the world is freezing. A new ice age has dawned. Billions have fled the glaciers. A cataclysmic war is coming. In orbit, a group of scientists are running the Winter Experiments, a last-ditch attempt to understand why the planet is cooling. None of the climate models they build make sense. But then they discover an anomaly, an unexplained variation in solar radiation...and something else. Close to the burning edge of the sun, they catch a fleeting glimpse of something that shouldn’t be there....

Living and slaving in Fill City One, you get used to the smell. We call it the Everpresent Stink. But every once in a while, on a spring day with a breeze, it clears away enough to remind us that there is something more out there. Most Fillers' wildest dreams would be just to get past the walls and live in the mainland. But my dream? It’s a little bigger. I’m going to Mars.

Geophysicist Jack Greer believes he may finally have found the resting place of the meteorite that wiped out the dinosaurs 65 million years ago. A few miles off the Yucatán coast, Jack and a team of scientists tow an aging drilling platform over the impact crater with the aim of securing a sample. But buried deep beneath the earth lies a shocking discovery that threatens to shatter everything we think we know about our species.

When itinerant cave diver James Tighe receives an invitation to billionaire Nathan Joyce's private island, he thinks it must be a mistake. But Tighe's unique skill set makes him a prime candidate for Joyce's high-risk venture to mine a near-Earth asteroid - with the goal of kick-starting an entire off-world economy. The potential rewards and personal risks are staggering, but the competition is fierce, and the stakes couldn't be higher. Isolated and pushed beyond their breaking points, Tighe and his fellow 21st-century adventurers must rely on each other to survive....

There is a starship in trouble, lost in the void, with no one awake to hear the alarms. A thousand specially selected people left a troubled and unsustainable Earth for another world. Their dream was a new start on a virgin planet 30 years away. Their ship was state-of-the-art and entirely automatic, it's passengers safely sleeping through the journey - but something has gone wrong, something unexpected.

Dr. Tyson Klein is a quantum physicist who has dedicated his entire life to his research. At CERN, he analyses data generated by the Large Hadron Collider, the world's biggest and most powerful particle accelerator. Now, Ty believes he's found a pattern in its output. It looks like an organised data stream, being broadcast over what he calls a quantum radio. Could it be a signal from another universe? A message sent from the future? Or something else entirely?

When half of mankind revolts and demands more opportunity, those at the top decide on a compromise: They will build the first colony ships and allow the rest to discover new worlds and start over. Twelve ships are built. The first is called the Orion. Many are eager to go, but only 100,000 are chosen for each vessel. Far from Earth, a new life awaits, and it promises the prosperity they've always wanted. But still, resistance stirs.

At the same time, an exiled crew of outcasts mines for rare minerals on a lone asteroid. When other scientists finally acknowledge Pedreira's alarming discovery, it becomes clear that these outcasts are the only ones who may be able to save our world, knowing that the Hole hurtles inexorably toward the sun.

They’ve watched us for centuries through the Rift. They’ve prepared. Invasion is inevitable. The Earth Fleet has known of the Watchers for years, unwilling to share the knowledge with humanity. Now it might be too late. Hidden away from the Fleet, one man is creating a new colony ship destined for the other side of the Rift, but he’s missing a few pieces. Three other people have varied paths to get there. Ace goes from the streets of Earth to the Fleet training facility on the moon. Flint, an ex-Fleet pilot, must decide if a job is worth his life.

At the turn of the 22nd century, scientists make a breakthrough in human spaceflight. Through a revolutionary method known as somaforming, astronauts can survive in hostile environments off Earth using synthetic biological supplementations. With the fragility of the body no longer a limiting factor, human beings are at last able to journey to neighboring exoplanets long known to harbor life. A team of these explorers, Ariadne O’Neill and her three crewmates, are hard at work in a planetary system 15 light-years from Sol, on a mission to ecologically survey four habitable worlds.

Logan West and Emma James grew up together but are now high school seniors going in totally opposite directions after graduation. When they are assigned to work together on one last history project, they hardly expect the monotony of high school life to change. Instead, as they decode a series of unexplained clues hidden within their history project itself, Logan and Emma manage to unfold an ancient mystery that has baffled scientists and archaeologists, one with powerful implications for the present day.

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.

Cities all around the world reported strange alien vessels descending. Some saw them as the heralds of a new age; others fired everything they had at them.
