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.

In 2005, the robotic probe “Huygens” lands on Saturn’s moon Titan. 40 years later, a radio telescope receives signals from the far away moon that can only come from the long forgotten lander.

Jupiter’s moon Io has an extremely hostile environment. There are hot lava streams, seas of boiling sulfur, and frequent volcanic eruptions straight from Dante’s Inferno, in addition to constant radiation bombardment and a surface temperature hovering at minus 180 degrees Celsius.

Russian billionaire Nikolai Shostakovitch makes an offer to the former crew of the spaceship ILSE. He will finance a return voyage to the icy moon Enceladus. The offer is too good to refuse—the expedition would give them the unique opportunity to recover the body of their doctor, Dimitri Marchenko.

After a long journey to Saturn’s moon Enceladus, spaceship ILSE is on its way back to Earth, carrying crucial cargo. The crew is exhausted and wants nothing more than a quick return home. Suddenly, a chain of malfunctions puts the expedition in peril.

All four bestselling books of the Ice Moon series are now offered as a set.

The survival of humankind is at risk, but nobody takes the warning of young astrophysicist Maribel Pedreira seriously. 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.

When an amateur astronomer discovers something strange on telescopic solar pictures, an explanation must be found. Is it merely artefact? Or has he found something totally unexpected? An expert international crew is hastily assembled, a spaceship is speedily repurposed, and the foursome is sent on the ride of their lives. What challenges will they face on this spur-of-the-moment mission to our central star?

There is a huge, bold black streak in the sky. Branches appear out of nowhere over North America, Southern Europe, and Central Africa. People who live beneath The Rift can see it. But scientists worldwide are distressed—their equipment cannot pick up any type of signal from it. The rift appears to consist of nothing. Literally. Nothing. Nada. Niente. Most people are curious but not overly concerned. The phenomenon seems to pose no danger. It is just there.

Nick Abrahams still holds the official world record for the number of space launches, but he’s bored stiff with his job hosting space tours. Only when his wife leaves him, however, does he try to change his life. He accepts a tempting offer from a Russian billionaire. In exchange for making a simple repair on Neptune’s moon Triton, he will return to Earth a multi-millionaire, enabling him to achieve his ‘impossible dream’ of buying his own California vineyard.

Where life as we know it is impossible, the real adventure begins.

Venus is a hostile planet, covered by active volcanoes. Nevertheless, NASA launches an expedition to search for life there, because the dense clouds of Earth's hot sister could offer good conditions for it. Their specially developed airship cruises in the clouds of Venus to serve as a research platform for its four astronauts.

When they discover dangerous activities on the glowing-hot surface, there can only be one explanation: A highly sophisticated life form must be at work.

In 2014, the ESA spacecraft Rosetta lands a small probe named Philae on 67P, a Jupiter-family comet. The lander goes radio silent two years later. Suddenly, in 2026, scientists receive new transmissions from the comet. Motivated by findings that are initially sensational but soon turn frightening, NASA dispatches a crewed spacecraft to the comet. But as the ship approaches the mysterious celestial body, the connection to the astronauts soon breaks. Now it seems nothing can be done anymore to stop the looming dark danger that threatens Earth ...

Peter Kraemer, a physics teacher with a passion for astronomy, makes a discovery that he himself can hardly believe: Stars disappear from one day to the next, with nothing left of them. The researchers he contacts provide reassuring and logical explanations for every single case. But when Peter determines that the mysterious process is approaching our home system, he becomes more and more anxious. He alone perceives the looming catastrophe. When he believes he has found a way to avert the impending disaster, he chooses to pull out all the stops, even if it costs his job, his marriage, his friends, and his life.

No one has ever ventured deeper into space than the four astronauts of Shepherd-1. The aim of their mission: to witness the creation of the cosmos. Using the sun as a lens, they are to align a flock of probes in such a way that the moment of the Big Bang becomes visible.

For astronomer Christine, this is a dream come true. So she is bitterly disappointed when the first images are obscured by a kind of veil that prevents any insight. She works obsessively to find a solution, but when she finally succeeds in lifting the veil, she sees something that would have better been kept hidden...

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.

An intelligent robot and two young people explore Proxima Centauri b, the planet orbiting our nearest star, Proxima Centauri. Their ideas about the mission quickly prove grossly naive as they venture about on this planet of extremes. Where are the senders of the call for help that lured them here?

Alone and desperate, Eve sits in the control center of an alien structure. She has lost the other members of the team sent to explore exoplanet Proxima Centauri b. By mistake she has triggered a disastrous process that threatens to obliterate the planet.

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. The unusual crew faces a Herculean task—should they survive the journey. No one knows what to expect from this alien planet.

The omnibus edition of the Proxima trilogy.

Two humans and a robot on their own in the Alpha Centauri system: Marchenko, Adam and Eve have found asylum on a planet inhabited by aliens. They could spend the rest of their lives here in peace. But apparently there are many more people who, like them, have been sent to alien systems without a return ticket and without being asked - castaways with uncertain fates who need their help.

Their alien rescuers generously offer to take them on a search in one of their spaceships. Although the trio doesn’t know whether their hosts are acting out of altruism, they embark on an odyssey with dangers so unpredictable that the saga is indeed written in the stars.

The Proxima Logfiles is a multi-part series based on the Proxima Trilogy, but can be read independently. Star Trek meets Lost in Space – reimagined with the scientific and technical realism of hard science fiction.

Luhman 16 is a binary system of brown dwarfs - stars that have failed to ignite the nuclear fusion process inside them. Therefore, the sun never rises on the planets orbiting them.

The crew of the spaceship "Majestic Draght", consisting of aliens and humans, must plunge deep into the darkness to help castaways fighting for their lives here, of all places. But then something happens that no one could have expected …

The spaceship Majestic Draght reaches a star system whose only planet is bombarded with deadly radiation from its sun.

Here, of all places, something happens that should never happen – and the crew sees their only salvation in landing on the mysterious planet orbiting the hostile star.

Two humans and a robot roam the universe in search of castaways. The Majestic Draght, a spaceship built by aliens and controlled by an AI, transports them from system to system at one-fifth the speed of light. But then the ship suddenly - and seemingly unstoppably - accelerates. Has the AI lost control of the propulsion system? Or is the AI pursuing its own plans?

The Draght’s new course targets a planet that would not have been the destination of the human-alien crew for a long time: Earth.

The Majestic Draght reaches a planet that could be a younger sibling of Earth’s sun. The Grosnops are looking for a second home, while the small human crew plans an experiment: How quickly does terrestrial life adapt to this alien environment? The experiment seems to fail - but then a crew member is kidnapped by strangers, and the intriguing exploration turns into a dramatic rescue mission.

Planet Suran is a paradise and offers the best conditions for life. Its diverse inhabitants are intelligent - all of them. According to legend, the builders, higher beings, breathed intelligence into the creation shortly after the world was created. Science sees it differently: biologists have found evidence that all genetic material of suranic life has been artificially altered in the recent past.

Olom doesn't know who is right, traditionalists or moderns, and he doesn't care because he has his own problems. He has been lovingly raised by his three parents, but still he is missing something: a being just like him. No one else on Suran has only two legs and two arms. No one moves as clumsily. A strange photograph promises Olom help. But to uncover his origins, he must enter places that no Suran before him has ever explored. Are the builders themselves hiding there?

The alien spaceship Majestic Draght is finally on its way to Earth. How will humans react to the gargantuan spaceship, whose technology is vastly superior to anything on Earth?

No sooner has the crew reached Saturn’s orbit than they lose control of the ship. The Omniscience - the artificial intelligence that controls the Draght’s systems, and which has always had a compelling interest in the solar system - has disappeared.

While the crew searches for the AI, the dark matter drive also fails. Suddenly the Draght is in danger of crashing into Saturn’s nearby moon, Enceladus, jeopardizing the enigmatic being at the bottom of the Enceladus Ocean.

For many billions of years, humans—having conquered the curse of aging—spread throughout the entire Milky Way. They are able to live all their dreams, but to their great disappointment, no other intelligent species has ever been encountered. Now, humanity itself is on the brink of extinction because the universe is dying a protracted yet inevitable death. They have only one hope.

The new heart of the Milky Way is a quasar, enclosed by a huge shell. It will provide energy to humankind for a long time. But then one maintenance probe after another disappears. Is someone trying to manipulate the quasar to destroy our galaxy in a giant explosion? Or is it just a few outlaws who are trying to steal some of the quasar’s energy for themselves?

In the 1980s, physicists at a lab in the Soviet Union find traces of strange data in the cosmic background radiation. Because powerful forces in the military believe these findings can be turned into a weapon for use in the cold war, the information gleaned by the physicists is kept under strictest secrecy.

For many billions of years, humans—having conquered the curse of aging—spread throughout the entire Milky Way. They are able to live all their dreams, but to their great disappointment, no other intelligent species has ever been encountered. Now, humanity itself is on the brink of extinction because the universe is dying a protracted yet inevitable death.

They have only one hope: The ‘Rescue Project’ was designed to feed the black hole in the center of the galaxy until it becomes a quasar, delivering much-needed energy to humankind during its last breaths. But then something happens that no one ever expected—and humanity is forced to look at itself and its existence in an entirely new way.

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.

A woman presumed dead fights her way through the hostile deserts of Mars. With her help, the NASA astronauts orphaned on the Red Planet hope to be able to solve their very worst problem.

Does the secret of Mars lurk beneath the surface of its south pole? A lone astronaut searches for clues about the earlier inhabitants of the Red Planet. Meanwhile, Rick Summers, having assumed the office of Mars City’s Administrator by deceit and manipulation, tries to unify the people on Mars with the weapons under his control.

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.
Challenges arise even before they reach Mars orbit. The MfE spaceship Santa Maria is damaged along the way. Only the four NASA astronauts can intervene and try to save their lives.

No one anticipates the impending catastrophe that threatens their very existence—not to speak of the daily hurdles that an extended stay on an alien planet sets before them. On Mars, a struggle begins for limited resources, human cooperation, and just plain survival.

For years astronomers have been searching for a planet beyond Neptune‘s orbit. They keep finding clues, but the decisive evidence of an actual sighting eludes them.

The four astronauts on board the Ganymede Explorer aren’t interested in scientific renown. They just need a safe place to hide out, as far as possible from any kind of civilization. But it seems apt that they of all people wind up being the ones to track down a previously unknown planet. They land full of enthusiasm and curiosity – it doesn’t occur to them to be afraid. But they don’t know what they’ve found. Amphitrite is no ordinary celestial body. It’s the black planet.

Despite all the dangers of the newly discovered Black Planet, two astronauts investigate the celestial body. They find clues to its legendary origin and incredible age, and soon realize that Amphitrite hides an even greater secret.

Meanwhile, the ancient newcomer approaches Earth in its unusual orbit. The black dust covering its surface grabs the attention of several competing companies because of its unique, profit-promising properties.

Thus begins a race to the planet, a celestial body which—as it turns out—humanity would have been better off letting pass by Earth untouched.

Two outlaws search for an astronaut who has risen from the dead. A team of mercenaries is tasked with uncovering the secret of the invader of our solar system, at any cost.

For both groups it seems that Amphitrite, the Black Planet, is the stage on which they must fight their battles. Nowhere are life and death so closely interwoven as on this strange world, which ultimately has its own way of intervening in events. If only humanity had kept its distance! Amphitrite is no ordinary celestial body. It is the black planet.

A planet in the endless emptiness of space, far from the warmth of any sun. And yet there are people who populate its vast caverns, living, working and loving. Since time immemorial, they have been on course for Andromeda, the neighboring galaxy of the Milky Way. This is the prophecy of the ancients, the one goal that unites them all, their cult.

But then the unthinkable happens: The journey stops because the planet enters the orbit of a mysterious object that can't be seen in any telescope. Scientists doubt its very existence, though they can't give any other explanation as to why the journey to Andromeda has come to an end.

And then the messages start.

Nova is a lonely planet, on its way to the Andromeda galaxy for ages. And yet it is inhabited - by people who have never known anything other than the caves beneath the surface that protect them from the vacuum and cosmic radiation.

A surprising encounter changes everything. The planet gets visitors who seem to have their own agenda and are so alien that communication seems futile. But they, too, have unexpected existential problems. Could cooperation with them avert the danger of missing Andromeda? Perhaps, were it not for a threat that has lain dormant inside the planet for millions of years and could destroy all life.

The star system is perfect. The arrivals have undertaken a long and dangerous journey—an expedition of no return—seeking helium-3, essential for the survival of their species. The discovery of this extraordinary solar system with its four gas giants offers a unique opportunity to harvest the rare isotope.

Then comes a disturbing discovery: They are not alone! Another fleet is here, and just as dependent on helium-3. And the two species are so fundamentally different that communication and compromise appear hopeless. All that remains is a fight to the death—and for the future…

No sooner has one of the last surviving humans delivered this bad news to the representatives of the Mendraki and the Iks than he disappears. Kimi, Norok, Tolkut, and Kasfok find themselves alone in a spaceship controlled by technology they do not understand, and together they must avert a threat whose source they do not know.
They have only one clue: They must locate the hidden supercomputer that preserves information about a dark chapter in the history of the strange bipeds – information that may save their peoples...

250 years ago, humanity nearly destroyed itself in the Great War. Shortly before, a spaceship full of researchers and astronauts had found a new home on Saturn's moon, Titan, and survived by having their descendants genetically adapted to the hostile environment.

The Titanians, as they call themselves, are proud of their cooperative and peaceful society, while unbeknownst to them, humanity is slowly recovering back on Earth. When a 20-mile-wide chunk of rock escapes the asteroid belt and appears to be on a collision course with Earth, the Titanians fear it must look as if they launched the deadly bombardment. Can they prevent the impact and thus avoid an otherwise inevitable war with the Earthlings?

2312: In the first-ever terraforming program, millions of drones are repairing the home of humanity, which had been rendered virtually uninhabitable by the Great War of 2299. Megacorporation Olympus manufactures and controls the autonomous repair swarms, and is building a widespread mining system in the asteroid’s main belt to harvest the resources urgently needed to restore Earth.

When the control center on Psyche loses contact with an automated mining station in the main belt, Olympus hastily assembles a small team to reboot the errant software. As soon as they land on the asteroid, Sara Renberg and her two teammates discover they are in the grip of a mysterious and powerful force – and Earth itself is the target of a devastating attack!

Judith Rosenberg, captain of the spaceship ARES, is under pressure. After the previous mission to Mars crashed, she is supposed to set down the first humans on the Red Planet. Maxim Goncharov, meanwhile, has other problems to contend with. He's in charge of building an international lunar base at the moon's south pole, where the sun almost always shines. But his crew is slowly running out of resources. Humankind seems to have lost interest in the moon. When the ARES encounters an interstellar visitor, the researchers on the moon uncover its true nature: A discovery with terrible consequences, as Judith and Maxim find out almost simultaneously.

The Wall: Eternal Day depicts a fateful chain of events that changes the solar system and all its inhabitants forever. But there are two sides to every fate. In The Wall: Eternal Night by Joshua T. Calvert, you will learn about the other side.
