Space History

They say you can't teach an old dog new tricks. But what about relativity? Physics professor Chad Orzel and his inquisitive canine companion, Emmy, tackle the concepts of general relativity in this irresistible introduction to Einstein's physics. Through armchair- and sometimes passenger-seat-conversations with Emmy about the relative speeds of dog and cat motion or the logistics of squirrel-chasing, Orzel translates complex Einsteinian ideas into examples simple enough for a dog to understand.

In the early 1990s, Motorola, the legendary American technology company, developed a revolutionary satellite system called Iridium that promised to be its crowning achievement. Light-years ahead of anything previously put into space, and built on technology developed for Ronald Reagan's "Star Wars", Iridium's constellation of 66 satellites in polar orbit meant that no matter where you were on Earth, at least one satellite was always overhead, and you could call Tibet from Fiji without a delay and without your call ever touching a wire.

A respected physics professor and author breaks down the great debate over the big bang and the continuing quest to understand the fate of the universe.

Social worker, activist, and cultural commentator Feminista Jones explores how Black women are changing culture, society, and the landscape of feminism by building digital communities and using social media as powerful platforms. As Jones reveals, some of the best-loved devices of our shared social media language are a result of Black women’s innovations, from well-known, movement-building hashtags (#BlackLivesMatter, #SayHerName, and #BlackGirlMagic) to the now ubiquitous use of threaded tweets as a marketing and storytelling tool.

From blanket fairs to night kings, curfews to crime, At Day's Close is an intriguing and captivating investigation into the night. Until now, this rich and complex universe in which we spend nearly half of our lives was a world long-lost to historians. Here, Ekirch explores how the night was lived in the past, through travel accounts, memoirs, letters, folklore, poems, court records and coroner's reports. More than this, it is a passionate argument in the case for less artificial light in an increasingly bright world.

The invaders are coming; the Posleen, a seemingly unstoppable horde who have conquered one star system after another, literally feeding on their conquests. Earth's dubious allies, the Darhel, have given the humans a number of highly-advanced technological devices, including a process for rejuvenating the aged, including trained and proven soldiers who otherwise would be too old to fight. Rejuvenation may give a critical edge, since to survive, the Earth must use every resource at hand.

Have you ever wondered if there are seasons on the moon or if space tourism will ever become commonplace? So has Dr. Maggie Aderin-Pocock. In fact, she earned her nickname “Lunatic” because of her deep fascination for all things lunar. In her lucidly written, comprehensive guide to the moon, Aderin-Pocock takes listeners on a journey to our closest celestial neighbor, exploring folklore, facts, and future plans.

After falling in love with the king's intended, Lewis Deathstalker is now exiled, an outlaw from the empire he faithfully served for so long. With Lewis out of the way, former Paragon Finn Durandal has led a silent coup to wrest control from the king and set himself up as the power behind the throne. But Durandal is not the Empire's biggest threat. The Terror that Owen Deathstalker prophesied nearly 200 years ago is almost upon them, and Owen is supposedly the only one who can save civilization from unspeakable horrors.

On June 6, 1761, the world paused to observe a momentous occasion: the first transit of Venus between the earth and the sun in more than a century. Through that observation, astronomers could calculate the size of the solar system - but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Fortunately, transits of Venus occur in pairs: eight years later, the scientists would have another opportunity to succeed.

In a drastic reevaluation of astronomy observations from Mahabharata, using high-tech tools of modern astronomy and low-tech tools of the logic of scientific discovery, Nilesh Oak’s extraordinary book presents ordinary theory of astronomy observations that would lead to a quantum jump in our understanding of the Mahabharata War

For centuries, it was assumed that our universe was static. In the late 1920s, astronomers defeated this assumption with a startling new discovery. From Earth, the light of distant galaxies appeared to be red, meaning that those galaxies were receding from us. This led to the revolutionary realization that the universe is expanding. The Red Limit is the tale of this discovery, its ramifications, and the passionately competitive astronomers who charted the past, present, and future of the cosmos.

Fatal Flight brings vividly to life the year of operation of R.101, the last great British airship - a luxury liner three and a half times the length of a 747 jet, with a spacious lounge, a dining room that seated 50, glass-walled promenade decks, and a smoking room.

If the United States couldn’t catch up to the Soviets in space, how could it compete with them on Earth? That was the question facing John F. Kennedy at the height of the Cold War. On February 20, 1962, when John Glenn blasted into orbit aboard Friendship 7, his mission was not only to circle the planet; it was to calm the fears of the free world and renew America’s sense of self-belief. Mercury Rising recreates the tension and excitement of a flight that shifted the momentum of the space race and put the United States on the path to the moon.

Amid the ongoing reckoning over America’s history of anti-Black racism, scores of monuments to slaveowners and Confederate soldiers still proudly dot the country’s landscape, while schools and street signs continue to bear the names of segregationists. With poignant, lyrical prose, cultural commentator Irvin Weathersby confronts the inescapable specter of white supremacy in our open spaces and contemplates what it means to bear witness to sites of lasting racial trauma.

After the Apollo program put 12 men on the moon and safely brought them home, anything seemed possible. In this spirit, the team at NASA set about developing the space shuttle, arguably the most complex piece of machinery ever created.

This is the dramatic and inspirational first-person story of theoretical physicist Dr. Ronald Mallett, who recently discovered the basic equations for a working time machine that he believes can be used as a transport vehicle to the past. Combining elements of Rocket Boys and Elegant Universe, Time Traveler follows Mallett's discovery of Einstein's work on space-time, his study of Godel's work on a solution of Einstein's equation that might allow for time travel.

The story of the men and women who drove the Voyager spacecraft mission, told by a scientist who was there from the beginning. The Voyager spacecraft are our farthest-flung emissaries--11.3 billion miles away from the crew who built and still operate them decades after their launch.

In the course of our enduring quest for knowledge about ourselves and our universe, we haven't found answers to one of our most fundamental questions: Does life exist anywhere else in the universe? Ten years and billions of dollars in the making, the Mars rover Curiosity is poised toanswer this all-important question.

What is space? It isn't a question that most of us normally stop to ask. Space is the venue of physics; it's where things exist, where they move and take shape. Yet over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time. The phenomenon - the ability of one particle to affect another instantly across the vastness of space - appears to be almost magical.

On a moonless night in January 1991, a dozen US aircraft appeared in the skies over Baghdad. To the Iraqi air defenses, the planes seemed to come from nowhere. Each aircraft was more than 60 feet in length and with a wingspan of 40 feet, yet its radar footprint was the size of a ball bearing. Here was the first extensive combat application of Stealth technology. And it was devastating.
