Earth Space Science

They destroyed the civilization of the ancient alien Elders thousands of years ago, and now they’re following Andy Clanton and the crew of the James Bowie back from the edge of the galaxy and into Alliance space, bent on wiping out all intelligent life in the galaxy. The Bugs probe for weakness, attacking new friends and old enemies, and forcing Andy and the others into union with forces that had tried to destroy them only months before and putting a wedge between the Earth and the Alliance.

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.

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. Incited by foreign enemies, stoked by mindless fear, the American public is wrapped in panic, and the country’s enemies use the opportunity to attempt a coup to seize control of America’s space assets. 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.

The marauders, terrors from deep space, hit us hard. Our starships shattered. Our armies collapsed. Our cities crumbled. As Earth smolders, the marauders imprison us in camps. They farm us like cattle. They torture us for sport. Earth weeps. But there is hope. The Ghost Fleet, an ancient alien armada, might still exist in deep space. In a single starship, Sergeant Marco Emery and his friends seek this mythical fleet. They must find it. They must return with its might. Or the marauders will kill us all.

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.

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.

In researching one of history's greatest scientific quests, a mission to measure the Earth and define the meter, Ken Alder stumbled on a 200-year-old secret: The meter, it turns out, is in error. This is a story of two men, a secret, and a timeless human dilemma: is it permissible to perpetuate a small lie in the service of a larger truth?

For years, they stalked us. Kidnapped us. Dissected us. For years, we feared them. Some call them "gray aliens". Some claim they crashed in Roswell. Others say they're just a myth. But legends often spring from terrifying truths. There are monsters in the dark. And their evil knows no bounds. We've faced aliens before. But nothing like this. This enemy is stronger, smarter, and crueler by far. And they want to kill us all. But we refuse to fall. We will muster all our courage. All our strength. We will tell the enemy: "Earth will rise!"

The marauders, vicious alien predators, brought us to our knees. They destroyed our fleets. They burned our cities. They butchered millions. But now we fight back. Across the ruins of Earth, we rise in rebellion. In the depths of space, we seek allies. And our last warship prepares for one final battle. It's a time for heroes. A time to show our human pride. Because Earth is our home. Earth is our birthright. Earth is eternal. We will save it. Or we will die on our feet.

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.

The sun's family of planets become a familiar place in this personal account of the lives of other worlds. Sobel explores the planets' origins and oddities through the lens of popular culture, from astrology, mythology, and science fiction to art, music, poetry, biography, and history. This intimate account is filled with fascination, beauty, and surprise.

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.

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.

In this epic conclusion to the first series in the Human Chronicles Saga, Adam Cain and his band of Human warriors are presented to the Supreme Leader of the Galaxy. With only minutes to live, Adam convinces the Juirean leader that Humans are not the enemy, but that both their races have been part of a diabolical plot for galactic domination orchestrated by the Klin. And yet just when the truth dawns on the Juireans, the planet Juir is attacked by Kracori forces, which leads to a whole new set of problems for Adam and his band of Human Super-Men.

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.

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.

There is a milestone in the evolution of every sentient race, a Tech Singularity Event, when the species achieves transcendence through its technological advances. Now the creatures known as humans are near this momentous turning point. But an armed threat is approaching from deepest space, determined to prevent humankind from crossing over that boundary - by total annihilation if necessary.

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.

Jake Adlar's goals in life were simple—possibly nonexistent. All he wanted was to fly a desk. Hence, he'd joined the Space Force, the service with the most extensive array of Earth-side clerical specialties. All he needed to make him happy was an office, a computer, his favorite coffee mug, and a never-ending pile of requisitions.

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.
