Human travel into space is an enormously expensive and unforgiving endeavor. So why go? In this accessible and authoritative book, astrophysicist Martin Elvis argues that the answer is the asteroid exploration, for the strong motives of love, fear, and greed. Elvis explains how each motive can be satisfied, and how they help one another. From the origins of life, to "space billiards," and space sports, Elvis looks at how asteroids may be used in the not-so-distant future.

Space exploration is as much a story of leadership and teamwork as it is a story of exploration and discovery. Leadership Moments from NASA delves into the organizational culture, leadership styles, and insights of NASA senior executives spanning five decades of human spaceflight, to share the lessons they learned from critical moments where they took on seemingly insurmountable challenges.

Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.

Award-winning science writer and documentarian Rod Pyle presents an insider's perspective on the most unusual and bizarre space missions ever devised inside and outside of NASA. The incredible projects described here were not merely flights of fancy....

Humans have always been fascinated by the possibility of extraterrestrial life, often wondering if we are alone in the universe. Drawing on nearly fifty years as a leader in planetary exploration, Louis Friedman brings into focus the subject of extraterrestrial life, separating knowledge from conjecture, fact from fiction, to draw scientific and technical conclusions that answer this enduring question. Friedman argues that intelligent life is probably rare in the universe but that simple life is likely abundant on millions or billions of planets waiting now to be discovered.

Is the human body built for Mars? NASA's studies on the International Space Station show we need to fix a few things before sending people to the Red Planet. Astronauts go into space with good vision and come back needing eyeglasses. Cognition and DNA expression could be affected for years. And then there's the discomfort of living in a tight space with crewmates, depression, and separation from the people you love.

With the ongoing advancement of AI and other technologies, our world is becoming increasingly intelligent. From chatbots to innovations in brain-computer interfaces to the possibility of superintelligences leading to the Singularity later this century, our reality is being transformed before our eyes. This is commonly seen as the natural result of progress, but what if there's more to it than that? What if intelligence is an inevitability, an underlying property of the universe?

Not long ago, the Solar System was the only example of a planetary system - a star and the bodies orbiting it - that we knew. Now, we know thousands of planetary systems, and have even been able to observe planetary systems at the moment of their birth.

On January 28, 1986, NASA's space shuttle Challenger exploded after blasting off from Cape Canaveral. Christa McAuliffe, America's "Teacher in Space", was instantly killed, along with the other six members of the mission. At least that's what most of us remember. Kevin Cook tells us what really happened on that ill-fated, unforgettable day. He traces the pressures - leading from NASA to the White House - that triggered the fatal order to launch on an ice-cold Florida morning.

Einstein's theory of gravity, as beautiful as it is, seems to be in direct contradiction with another theory he helped create: quantum mechanics. From the explosions of neutron stars and the collisions of black holes to the modern scientific process as a means to seek truth and understanding in the cosmos, this audiobook takes the listener on a journey of learning and discovery that has been 100 years in the making.

In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

This is a fascinating introduction to the history of Western astronomy, from prehistoric times to the origins of astrophysics in the mid-19th century. Historical records are first found in Babylon and Egypt, and after two millennia the arithmetical astronomy of the Babylonians merged with the Greek geometrical approach to culminate in the Almagest of Ptolemy. This legacy was transmitted to the Latin West via Islam and led to Copernicus's claim that the Earth is in motion.

The marvelous complexity of the universe emerges from several deep laws and a handful of fundamental constants that fix its shape, scale, and destiny. Where did these laws and these constants come from? And why are the laws so fruitful when written in the language of mathematics? Author Peter Atkins considers the minimum effort needed to equip the universe with its laws and its constants. He explores the origin of the conservation of energy, of electromagnetism, of classical and quantum mechanics, and of thermodynamics, showing how all these laws spring from deep symmetries.

During the early and most dangerous years of the cold war, a handful of Americans, led by President Dwight D. Eisenhower, revolutionized spying and warfare. In great secrecy and beyond the prying eyes of Congress and the press, they built exotic new machines that opened up the Soviet Union to surveillance and protected the United States from surprise nuclear attack. Secret Empire is the dramatic story of these men and their inventions, told in full for the first time.

In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.

In Search of a Theory of Everything takes listeners on an adventurous journey through space and time on a quest for a unified "theory of everything" by means of a rare and agile interplay between the natural philosophies of influential ancient Greek thinkers and the laws of modern physics.

We now know that the universe is mostly dark, made up of particles and forces undetectable by our most powerful telescopes. The discovery signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we're made. Vera Rubin played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin's life and work.

The United States Space Force has a noble mission - to protect America, to support our allies, and to support our nation's interest as we, along with other nations, move out into the little patch of the universe that is our home system. The desire to establish a US Space Force has been around for decades, in both science fiction and in the minds of people who attempt to seriously consider what our nation needs in order to deter future wars (and if necessary, to fight and win them).

This compelling book describes how the Big Bang theory arose, how it has evolved, and why it is the best theory so far to explain the current state of the universe. In addition to understanding the birth of the cosmos, listeners will learn how the theory stands up to challenges and what it fails to explain. Karen Fox provides clear answers to some of the hardest questions including: Why was the Big Bang theory accepted to begin with? Will the Big Bang theory last into the next century or even the next decade? Is the theory at odds with new scientific findings?

Mars has been a source of fascination and speculation ever since the ancient Egyptians observed its blood-red hue and named it for their god of war and plague. But it wasn't until the 19th century when "canals" were observed on the surface of the Red Planet, suggesting the presence of water, that scientists, novelists, filmmakers, and entrepreneurs became obsessed with the question of whether there's life on Mars. The Big Book of Mars is the most comprehensive look at our relationship with Mars - yesterday, today, and tomorrow.
