Earth Space Science

In 1977, two extraordinary spacecraft called Voyager were launched to the stars. Affixed to each Voyager craft was a gold-coated copped phonograph record as a message to possible extra-terrestrial civilizations that might encounter the spacecraft in some distant space and time.

In 1959, the Soviet probe Luna 3 took the first photos of the far side of the Moon. Even in their poor resolution, the images stunned scientists: The far side is an enormous mountainous expanse, not the vast lava plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. When the Earth Had Two Moons is an astonishing exploration of planet formation and the origins of life by one of the world’s most innovative planetary geologists.

On board an X101 stealth aircraft, Lauren, Jack, and Mike arrive at the secret location of Sky Dreamer Corp - a place equipped with technology and resources far more advanced than anything they could have ever imagined.

Critically acclaimed author Alastair Reynolds holds a well-deserved place “among the leaders of the hard-science space opera renaissance." ( Publishers Weekly). In Blue Remembered Earth, Geoffrey Akinya wants nothing more than to study the elephants of the Amboseli basin. But when his space-explorer grandmother dies, secrets come to light and Geoffrey is dispatched to the Moon to protect the family name - and prevent an impending catastrophe.

Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than 50 times its total volume of liquid water. Could there be organisms living in their depths?

When Nicole Stott first saw Earth from space, she realized how interconnected we are and knew she had to help protect our planetary home. In Back to Earth, Stott imparts essential lessons in problem-solving, survival, and crisis response that each of us can practice to make change. She knows we can overcome differences to address global issues, because she saw this every day on the International Space Station. Stott shares stories from her spaceflight and insights from scientists, activists, and changemakers working to solve our greatest environmental challenges.

Recruited to follow the last signal of the mysterious Elders to a system halfway across the galaxy, Andy joins the crew of the James Bowie for another adventure into the unknown. The journey will be filled with mystery and wonder, with strange life seeded on far-flung worlds by the godlike Elders…and with danger. For the Elders didn’t leave our galaxy of their own accord. They were driven out by an implacable enemy, something beyond their understanding…and ours.

Andy Clanton and the crew of the Jambo return to Earth for the final battle with the Bugs…but the real threat is back home.

Andy and the others are forced to go on the run, while Pops stays on Earth to organize a resistance. Andy and Julie steal the Bellerophon and seek answers from the Elder AI, Graham.

Darius has enjoyed a nice break from an action packed integration into the GGA. With Earth in limbo, and a lost colony likely in need of help, he knows his vacation is on borrowed time. He owes the Merchant Marines, Pavia, and humanity itself to do more, to be more. So when life is turned upside down again, he ventures back into the stars, helping those he can, when he can. The adventure is intense, his family bonds are tight, and the dangers ever-present.

Former NASA astronaut Terry Virts offers an insider's guide to astronauting—a behind-the-scenes look at the training, the basic rules, lessons, and procedures of space travel, including how to deal with a dead body in space, what it’s like to film an IMAX movie in orbit, what exactly to do when nature calls, and much more, in 51 brief chapters.

Zetetic Astronomy is the magnum opus of Samuel Rowbotham (1816-1884), a self-taught polymath, debater, faith healer, and early advocate of Utopian socialism. Drawing from a wide variety of contemporary sources, Christian scripture, and his own investigative and experimental skills, Rowbotham advocated tirelessly for his thesis that the true shape of the Earth was a plane, refuting all suggestions of rotundity. His arguments continue to captivate, persuade, and entertain up to the present day.

Satellites may exist out in space, but they let us study Earth from the outside looking in. From climate change to natural disasters and more, find out how scientists are using satellites to tackle some of our world's most challenging problems.

Flat Earth has long been denigrated, derided, and disparaged as being the most crackpot of all conspiracy theories, marginalized, mocked, and ridiculed for centuries as being an ignorant ancient unscientific worldview, but the facts of the matter are far from what you have been told. When thoroughly examined and diligently researched with an open-mind, any skeptical critical-thinker will find it is actually the tilting, wobbling, spinning space-ball Earth promoted by NASA and taught in schools that is truly ridiculous and unscientific.

Five years ago, we won our first galactic war. We defeated the scum, a race of alien centipedes. But the marauders are stronger, smarter, and crueler by far. And they will show us no mercy. Marco Emery, hero of the last war, struggles today as a civilian. Shell shock cripples him. Nightmares haunt him. Yet now he must become a soldier again. Now his old platoon must reunite. Together, they must defeat the greatest threat Earth has ever known. Or humanity will fall.

It's all-out war. Our cities fall. Millions die. The scum, these cruel aliens from deep space, are determined to kill us all. So we must kill them. Humanity musters its greatest fleet. Thousands of starships rally. Millions of soldiers deploy. For Earth to stand a chance, we must invade the aliens' home world. We must destroy their planet. Before they destroy ours. Earth's fleet flies through space. We fly toward millions of enemy ships. We fly to almost certain death.

In the fourth book of the Extinction Wars series, Abaddon commands a Karg-Jelk Super Fleet bent on annihilating humanity. He's the galaxy's most ruthless strategist wielding superior technology. That includes the perfect raid-ships, able to teleport anywhere at will. Humanity has Commander Creed, and he has his Assault Troopers. He's going to take the fight to the enemy. He's buying time, learning secrets and setting up for the greatest space battle in the Orion Arm.

Hackett, in his trusty ship the Perseus, is not just a space traveller—beginning his travels with an expedition to Neptune and back—but, thanks to the time-dilation effect, a time traveller as well. His new mission will take him to Andromeda, to get a close-up look at the constellation which will eventually crash into the Milky Way, and give humanity a heads-up about the challenges which are coming. A mission which will take him five million years to complete. Not only is Hackett exploring unknown space, but he will return to a vastly different time.

They came from deep space. They came to destroy us. Fifty years ago bloodthirsty aliens devastated the Earth. Most of humanity perished. We fell into darkness. But now we rise from the ashes. Now we fight back. Marco Emery was born into the war. After his mother is killed, he joins the Human Defense Force, Earth's ragtag army. Emery must survive basic training, become a soldier, and finally face the aliens in battle. Against the alien onslaught, Earth stands alone. But we will fight. We will rise. We will win.

Earth, from space, looks like a shimmering gem suspended in an inky, infinite expanse. But this serene image masks the magnificent and volatile interior forces that make life possible for millions of species on the surface. The placid appearances of our neighboring planets similarly belie their powers—and science fiction-worthy features, like diamond rain.

Ambassadors from Earth relates the story of the first unmanned space probes and planetary explorers - from the Sputnik and Explorer satellites launched in the late 1950's to the thrilling interstellar Voyager missions of the '70's - that yielded some of the most celebrated successes and spectacular failures of the space age. Jay Gallentine delivers a quirky and unforgettable look at the lives and legacy of the Americans and Soviets who conceived, built, and guided those unmanned missions to the planets and beyond.
