Earth Space Science

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?

The Earth has changed. War is now fought in an alien virtual reality - the Game - where many of the players are anything but human. Now part of the Black Rose guild, Alan heads to the Academy to level up and get stronger. He hopes to make allies and learn skills to win the battles to come. But with everyone pursuing their own agendas, what can one gamer do in a universe he still doesn't fully understand?

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.

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.

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.

They call themselves the next step in human evolution. But we call them "scummers." They are hybrids. Humans with alien DNA. They attacked us. They butchered us. Now we fight back. Under the leadership of Einav Ben-Ari, our brave soldiers fly to the scummer planet. To war. But we face a terrifying foe. The scummers are stronger than us. Faster. Fiercer. And their queen is none other than Lailani de la Rosa . . . Ben-Ari’s oldest and best friend.

Welcome to the alien zoo. In here, you’ll meet a variety of life from across the universe. Floating balloons of flesh from a gas giant’s storm. Sentient moss that controls golems of stone. Towering arachnids whose webs can entangle starships. And in one enclosure… humans. Us. This zoo, you see, is run by powerful aliens. To the zookeepers, we are mere animals. Marco, Addy, and Einav are soldiers. Together, they fought many wars. And won them all. But now they’re trapped in a cage. Disarmed. Demeaned. Animals on display.

Alex Archer is a soldier now, the only civilian survivor from Scorpio to join the NAC Defense Corps. With their training complete, Alex and her friend Private Isa Cressey find themselves on emergency combat deployment with their new unit. The destination is the Alpha Corvi system, where an allied warship has vanished. Alex can guess why.

Earth burns. After generations in exile, we returned to our long-lost planet. Scarred. Haunted. Survivors. We - the last humans - are finally home. But our enemies still crave our blood. Seven alien species unite. Seven fleets bombard our planet. Seven armies invade our beautiful world. They have one goal: To kill us all. We refuse to lose Earth again. We will resist. We will fight for every hill, every valley, every stone, and blade of grass. We will defend our planet. At any cost. Together, we will raise our voices. We will sing the song of Earth. We will tell the enemy: Earth is ours!

Aliens ripped a hole above Earth, arriving with a massive space station. I sorta figured we'd be enslaved to fight in their wars or exterminated for our resources. Nope. The hip-high Iglax were merchants with ugly squished faces and thick blue fur. While they weren't much to look at, they sure did have some wonderous technology.

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.

Beliefs about the shape of the earth have varied over the millennia, but the Ancient Greeks were able to observe that our planet is round and even Eratosthenes attempted to measure its size. It was not until explorers had fully charted the globe that most people were really able to comprehend its spherical shape.

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.

Former elite Federation soldier, now turned space pirate, Jackson Burke has done his best to turn his life around - for the better. He isn't prepared when fate leaves a woman's safety totally in his hands. Since heroes don't leave a damsel in distress - and despite being outlaw pirates - the crew considers themselves the good guys, so Jackson assumes responsibility for the beauty.

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.

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.

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.

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.

Earth burns. We call them the scum. They came from deep space. Creatures of claws and endless malice, they ravage the world.
