Late in the 21st century, Earth receives what looks like an urgent plea for help from planet Proxima Centauri b in the closest star system to the Sun. Astrophysicists suspect a massive solar flare is about to destroy this heretofore-unknown civilization. Earth's space programs are unequipped to help, but an unscrupulous Russian billionaire launches a secret and highly-specialized spaceship to Proxima b, over four light-years away.

NASA finally made it. The very first human has just set foot on the surface of our neighbor planet. This is the start of a long research expedition that sent four scientists into space. But the four astronauts of the NASA crew are not the only ones with this destination. The privately financed "Mars for Everyone" initiative has also targeted the Red Planet. Twenty men and women have been selected to live there and establish the first extraterrestrial settlement.  

Set to embark on NASA's first expedition to the outer planets, the crew of the spacecraft Magellan learns someone else has beaten them by a few decades: a top-secret Soviet project codenamed Arkangel. Now during their long race to the Kuiper Belt, astronauts Jack Templeton and Traci Keene must unwind a decades-old mystery buried in the pages of a dead cosmonaut's journal. The solution will challenge their beliefs about the nature of humanity, and will force the astronauts to confront the question of existence itself. 

Late at night inside the two-person Dragon spacecraft resting on the frozen surface of Saturn’s moon Enceladus, Derya Terzi put on headphones and became the first Earthling to hear the sloshing of the enormous subsurface ocean beneath his feet. Intoxicated with the promise of discovery, he could have sworn it was whispers between inscrutable creatures of the deep. He was convinced they were days away from settling the most profound and existential mystery known to humanity: are we alone in the universe?

Quinn Black is having the worst day ever...over and over again. The same car blocking his driveway, the same horrific accident he witnesses, the same cop that keeps preventing him from saving his boss from dying in it, and the same memory of a girl from his past that gets sharper each time. Then he realizes he has the power to travel through time and change the future. Could he prevent terrorist attacks? Natural disasters? The deaths of friends? Before long, Quinn is thrust into the greatest race in human history.

Theodorus was a dreamer. As a child, he dreamed of aeroplanes, rockets and outer space. When the wild card virus touched him and transformed him into a monstrous snail centaur weighing several tons, his boyhood dreams seemed out of reach, but a Witherspoon is not so easily defeated. Years and decades passed, and Theodorus grew to maturity and came into his fortune...but still his dream endured.

What lies on the dark side of the moon could change the course of humanity forever. When a Chinese rover discovers an alien technology on the dark side of the moon, it is up to Richard "Rock" Crandon and his NASA team of scientists and engineers to devise a way to return before the Chinese and Russians. Forced to deal with bureaucratic oversight and a complex team of personalities, Rock Crandon pushes his team to their limits.

Synthetic Intelligence. Thought impossible, but Dr. Wallace Theren has pushed the boundaries of computational science, creating an artificial mind capable of conscious thought. If the first synthetic intelligence is to survive its early years, it'll need friends, but more importantly, it'll need a family. And together, they'll need to show their enemies they're worth saving...or fearing.

Dib is an Earthlike planet, only slightly smaller, with shorter days and longer years, in orbit around twin suns. On the continent of Geo, in the city of Velon in the nation of Inimata, a man lies dead in his study. In life, Professor Orno Linus was a world-class scholar: an astrophysicist, a dead-language linguist, and an expert in (and apparent true believer of) the religious concept of the Cull, i.e., the end of the world. Widely respected, nothing about Linus’s expertise suggests somebody might want him dead.

Mark Thomas is a sailor on a freighter ferrying people and lithium ore between the utopian colony world, Elysium, and Earth. The starship is sabotaged, the crew presumed lost. But there's one survivor. Alone, Mark finds safe harbor in the barely charted star system, Trappist-1. Marooned, he thought that his biggest challenge was how to call for help. When he discovers that something ancient and dangerous is also marooned in the archipelago of a star system, his plight goes from bad to worse.

Commander Scott McNabb and the crew of the science vessel, Hermes, are three years into a five-year-long survey of the asteroid belt when they discover a derelict spaceship in orbit around a binary asteroid. The ship contains an experimental quantum device, lost while en route to a research colony on Europa.

The aftermath of the virus left the world in shambles. Humanity was centuries from recovering. The devastation was caused not by pestilence and death as in past plagues, but by immortality, vitality, and infertility. The pandemic was so transformative that it became known as simply the Event. John Fitzpatrick, retired FBI agent, is consumed with exposing what, or who, is behind the Event. As John looks for answers, he must navigate a new world created by the Event, decades of world-wide depression and war, messianic cult leaders, and a meddlesome AI. 

More than a century ago, Earth was suffering under the weight of overpopulation and ever-dwindling resources. Humanity’s best and brightest were commissioned to create a means to escape the overcrowding of Earth, and to branch out and live among the stars. Their efforts were hampered by the seeming impossibility of faster-than-light travel, until a team of researchers discovers an usual answer they call “the Lightrail”.  On the eve of Earth’s first successful jaunt to the stars, however, a powerful organization called Earth First commits a horrible act of terrorism.

Harry Rogers and Jess Cook stumbled into the technological remnants of an alien presence on Earth. Now everyone wants to take it from them. With both the government and a ruthless criminal family hot on their trail, they can’t afford even one mistake. If they win, they get a ticket to the stars. If they fail, they get an unmarked grave.

In the middle of climate-change crises, there is no mood for space-exploration stunts - but Reid Malenfant, elderly, once a shuttle pilot and frustrated would-be asteroid miner, decides to go take a look anyway. Nothing more is heard of him. But his ex-wife, Emma Stoney, sets up a trust fund to search for him the next time the Kernel returns...By 2570 Earth is transformed. A mere billion people are supported by advanced technology on a world that is almost indistinguishable from the natural, with recovered forests, oceans, ice caps.
