Earth Space Science

Earth is the only planet known to support life. It has plenty of water, it's the right temperature, and it has a blanket of gases to protect it. Explore your own home planet in this book about Earth.

For Sheriff Duke, the danger has reached the final countdown. Captured, tortured, beaten, but undefeated, it’s 60 seconds to midnight, and the only way to save his wife and daughter is through the fugitive he left home to hunt. But the real enemy isn’t what they seem, and the history of the forgotten Earth is about to be rewritten. Will any of it matter if there’s no one left to read it?

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.

With wonder, wit, and flair - and in record time and space - geophysicist David Bercovici explains how everything came to be everywhere, from the creation of stars and galaxies to the formation of Earth's atmosphere and oceans to the origin of life and human civilization. Bercovici marries humor and legitimate scientific intrigue, rocketing listeners across nearly 14 billion years and making connections between the essential theories that give us our current understanding of topics as varied as particle physics, plate tectonics, and photosynthesis.

In this one-of-a-kind memoir, Jack Clemons - a former lead engineer in support of NASA - takes listeners behind the scenes and into the inner workings of the Apollo and Space Shuttle programs during their most exciting years. Discover the people, the events, and the risks involved in one of the most important parts of space missions: bringing the astronauts back home to Earth. Clemons joined Project Apollo in 1968, a young engineer inspired by science fiction and electrified by John F. Kennedy's challenge to the nation to put a man on the moon.

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!

They’re here. They’ve arrived. And they’re all eyes. The Voltarian scouting party - illegal aliens extraordinaire - on a top-secret expedition led by one Jettero Heller, Royal Officer of the Fleet. His mission: rescue the planet from pollution - and make it safe for the upcoming invasion. His problem: The planet may not want to be saved - and the invasion may just be a trick.

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.

Kayan has emerged from the Hoyon citadel repaired and refreshed, though she’s a bit cagey. Why would she share what kind of upgrades the healing process bestowed upon her? Noah Gantz is just glad to be back in the action, seeking Seer secrets, a way to save two galaxies, and finding Kilis Dane Ryger before Celia and Ryg destroy Kayan to get their answers. When Kayan’s crew learns Dane may have genetically modified Azok warships, they pursue the clues back to the Milky Way and Earth.

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.

It finally happened. Commander Thrax Ti Ix created a hyper-spatial tube for the Swarm Imperium. Across thousands of light-years, a vast armada of warships is heading for Earth to burn the homeworld down to its bedrock as the Swarm begins its genocidal campaign against the human race. No one - not the New Men, the Spacers, the Wahhabi Caliphate, or Star Watch - has faced such staggering odds. Alone or united, it makes no difference.

Earth is rising in the House of Voltar.... And there’ll be hell to pay! That’s right. The invasion is on...and it’s coming soon to a galaxy near you. The action couldn’t be hotter, and the plot couldn’t be more diabolical. Earth is coming to Voltar - and the Voltarians won’t know what hit them. Murder, blackmail, drugs, psychoanalysis, PR firms, sex-crazed teenyboppers, riots in the streets, women in chains. These are the powerful secret weapons of war.

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.

A menacing wasteland. A destructive new weapon. A planet on the edge of catastrophe. Sheriff Duke can’t rest. There’s no time to slow down. The threats are unending. The enemy unyielding. If he wants to stop the apocalypse, he’ll have to cross a treacherous wasteland where the cannibals and murderers are the least of his worries, and the creatures infesting the landscape aren’t the most dangerous thing in his path. The race is on, the doomsday clock is counting down, and if he fails it will be more than his wife and child that are caught in the fallout. It’ll be the world.

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.

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.

At last, the Earth and the Colonial Union have begun formal discussions about their relationship in the future - a chance for the divisions in humanity to be repaired. The diplomats and crew of the Clarke are on hand to help with the process, including Ambassador Ode Abumwe and CDF Lieutenant Harry Wilson, both of whom were born on Earth. But not everyone wants the human division to be repaired.... And they will go to great lengths to make sure it isn’t....

A corporate aristocracy descended from Africa rules a colony on a distant planet. Life here is easy—for the rarified and privileged few. The aristocrats enjoy a powerful cybernetic technology that extends their life spans and ensures their prosperity. Those who serve them suffer under a heavy hand. But within this ruthless society are agents of hope and change. In a secret underwater laboratory, a separatist cult has created a threat to the aristocracy. The Primes are highly intelligent, manipulative products of genetic engineering, designed to lead a rebellion.

The Iglax Star Empire’s tried twice now to throttle this upstart species before they could expand beyond Sol. They once used humans for cheap mining, cheap labor, and cheap laughs. But with each attempt, humanity’s gotten stronger, spread across more star systems, and found new allies. Now the Iglax are preparing for war.
