Earth Space Science

For millennia, the planet Harmony has been protected by the Oversoul, an artificial intelligence programmed to prevent thoughts of war and conquest from threatening the fragile remnant of Earth's peoples. But as the Oversoul's systems have begun to fail, a great warrior has arisen to challenge its bans.

Five years ago, the US Space Force became a reality. And while those writing the checks took things very seriously, the other military branches did not. As a result, Space Force was populated by undesirables. My name is Captain Ethan Stone, a decorated member of SEAL Team Six turned Space Force "recruit". Flash forward five years and between tenses. President West is in office. Power has shifted. And Space Force is defunded. With just a handful of us still living on base, we find ourselves being evicted. But before all of us can leave, aliens invade.

Earth evolves. From first atom to molecule, mineral to magma, granite crust to single cell to verdant living landscape, ours is a planet constantly in flux. In this radical new approach to Earth’s biography, senior Carnegie Institution researcher and national best-selling author Robert M. Hazen reveals how the co-evolution of the geosphere and biosphere - of rocks and living matter - has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.

Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behavior of matter in a curved spacetime. The second is quantum mechanics. This theory describes the properties and behavior of matter and radiation at their smallest scales.

The stories in The Dying Earth introduce dozens of seekers of wisom and beauty, lovely lost women, wizards of every shade of eccentricity with their runic amulets and spells. We meet the melancholy deodands, who feed on human flesh and the twk-men, who ride dragonflies and trade information for salt. There are monsters and demons. Each being is morally ambiguous: The evil are charming, the good are dangerous. All are at home.

Only an ember of humanity survived the first Xaros invasion. Now the Xaros return to deliver the final blow to Earth and her defenders. A moon carrying an armada of Xaros drones unleashes its deadly cargo on the solar system. Fortress Mars stands between the enemy and an ill-defended Earth. While the battle rages over the red planet, the Breitenfeld must launch a desperate mission to Pluto to cut off enemy reinforcements. Earth stands on the brink of ruin, and humanity needs every hero it can find to turn back the tide of destruction.

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.

More than half a century after humans first walked on the Moon, exciting new space adventures are in the works. Thanks to major advances in rocketry, robotics, and other space technologies, humanity is on the verge of returning to the Moon, exploring Mars, building permanent orbiting space stations, expanding space tourism, and pushing the boundaries of exploration throughout the solar system and beyond. The Future of Space Exploration explores these exciting developments in 12 half-hour episodes, hosted by aerospace engineer and executive Dr. Ariel Ekblaw.

The comparative utopia of 23rd-century Earth is about to go dreadfully awry when a seemingly benign alien race is abruptly revealed to be one of the worst threats humanity has ever faced. Driven by an intense religious extremism, the Olyix are determined to bring everyone to their version of god as they see it. But they may have met their match in humanity, who are not about to go gently into that good night or spend the rest of their days cowering in hiding.

With the continuing failure of the Oversoul, the artificially intelligent guardian computer of the planet Harmony, the human colonists have begun to repeat the devastations of war and conquest wrought on Earth. To repair itself and avert disaster, the Oversoul has called a group of 16 refugees from the fallen city of Basilica to a hidden, abandoned spaceport where the ancient starships lie.

An ancient foe lurks in the shadows...licking its wounds and assembling its forces. Risen from the ashes and shrouded in darkness, these ancient beings are waiting for the perfect opportunity to strike back and set the universe on fire. After their world is ambushed in a devastating onslaught, the Star Alliance is nearly wiped out in one fell swoop. Hotheaded pilot Chase Athanatos leads the barely surviving fleet to the far edge of space and a small backwater planet.

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.

A collection of short stories gathered from the far reaches of the Space Team Universe. Some of these stories have been available elsewhere over the past few months, while others are new for this collection.

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?

Regarded as a masterpiece today, 2001: A Space Odyssey received mixed reviews. Despite the success of Dr. Strangelove, director Stanley Kubrick wasn't yet recognized as a great filmmaker, and 2001 was radically innovative, with little dialogue and no strong central character. Author Michael Benson explains how 2001 was made, telling the story primarily through the two people most responsible for the film, Kubrick and science fiction legend Arthur C. Clarke. Benson interviewed Clarke many times, and has also spoken at length with Kubrick's widow, Christiane.
