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.

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!

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.

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.

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.

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…
