Earth Space Science

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.

According to Sumerian scholar Zecharia Sitchin, a superior race of beings once inhabited our world. In The 12th Planet—the product of 30 years of intensive research—Sitchin persuasively argues that humanity sprang from extraterrestrial forebears. In this remarkable account, you'll hear the story of how these ancient visitors traveled to Earth from the stars and planted the genetic seed that would ultimately blossom into a remarkable species—the human being.

The basilisks, cruel alien serpents, attacked our world. They bombed us. Hunted us. Butchered us without pity. But now we will be the hunters. We will assemble a fleet. We will cross the vastness of space. And for the first time, we will strike the enemy on his own soil. It's a time for courage. A time for heroes. We will no longer hide in bunkers. We will no longer die like sheep. Freedom will be won with blood and fire. Freedom will be the legacy of Earth. We are the last humans. And we will win!

Humanity pushed its way to the stars—and encountered the Gbaba, a ruthless alien race that nearly wiped us out. Earth and her colonies are now smoldering ruins, and the few survivors have fled to distant, Earth-like Safehold, to try to rebuild. But the Gbaba can detect the emissions of an industrial civilization, so the human rulers of Safehold have taken extraordinary measures: with mind control and hidden high technology, they've built a religion in which every Safeholdian believes, a religion designed to keep Safehold society medieval forever.

It’s been eight years since an alien invasion drove a small surviving group of settlers to seek refuge in an underground shelter. Cut off from the rest of humanity, the ragtag band has maintained a narrowly functioning colony due to communal effort and salvage runs. Alex Archer has her own duties as a dog handler. While this off-world colony may be harsh, Ash, Alex’s black shepherd raised to sense threats, makes living in it a little nicer.

In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.

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.

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

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?

The long-awaited follow-up to Voyager: Architects of Infinity from the New York Times best-selling author and cocreator of Star Trek: Picard! As the crew of the Full Circle fleet works to determine the fate of their lost ship, the Galen, a struggle for survival begins at the far edge of the galaxy. New revelations about Species 001, the race that built the biodomes that first drew the fleet to investigate planet DK-1116, force Admiral Kathryn Janeway to risk everything to learn the truth.

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.

From the deep void, the Xaros came for humanity. Unfeeling, uncaring drones swept over humanity's nascent presence in the outer solar system. When word reached Earth… we weren't ready. Only one man knew the truth of the threat and he was powerless to help anyone survive. Strike Marines fight through Los Angeles under assault by murderous drones. A fighter pilot determined to reunite with his family. Armor soldiers stand against the darkness. This is the story of the Fall of Earth.

Many of us know that the Moon pulls on our oceans, driving the tides, but did you know that it smells like gunpowder? Or that it was essential to the development of science and religion? Acclaimed journalist Rebecca Boyle takes listeners on a dazzling tour to reveal the intimate role that our 4.51-billion-year-old companion has played in our biological and cultural evolution.

One hundred and fifty years from now, in a world where Africa is the dominant technological and economic power, and where crime, war, disease and poverty have been banished to history, Geoffrey Akinya wants only one thing: to be left in peace, so that he can continue his studies into the elephants of the Amboseli basin. But Geoffrey's family, the vast Akinya business empire, has other plans.

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.

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.

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.
