Mars is back. Suddenly everyone - from Elon Musk to Ridley Scott to Donald Trump - is talking about going to the Red Planet. When the Apollo astronauts walked on the Moon in 1969, many people imagined Mars would be next. However, NASA's Viking 1, which landed in 1976, was just a robot. The much-anticipated crewed mission failed to materialise, defeated by a combination of technological and political challenges. Four decades after Viking and almost half a century after Apollo, technology has improved beyond recognition - and politics has changed just as much. As private ventures like SpaceX seize centre stage from NASA, Mars has undergone a seismic shift - no longer just about science, it's become the prime destination for future human expansion and colonisation. But what's it really like on Mars, and why should anyone want to go there? How do you get there and what are the risks? Astrophysicist and science writer Andrew May answers all these questions and more, as he traces the history of our fascination with the Red Planet.
Einstein s theory of general relativity opens the door for the study of other possible universes and weird universes at that. The Book of Universes gives us a stunning tour of these potential universes, introducing us to the brilliant physicists and mathematicians who first revealed these startling possibilities. John D. Barrow then explains the latest insights that physics and astronomy have to offer about our own universe, showing how they lead to the concept of the multiverse the universe of all possible universes."
In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times bestselling author of Warped Passages and Knocking on Heaven's Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth.
Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs.
Working through the background and consequences of this proposal, Randall shares with us the latest findings--established and speculative--regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos' history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.
Space is a world devoid of the things we need to live and thrive: air, gravity, hot showers, fresh produce, privacy, beer. Space exploration is in some ways an exploration of what it means to be human. How much can a person give up? How much weirdness can they take? What happens to you when you can't walk for a year? have sex? smell flowers? What happens if you vomit in your helmet during a space walk? Is it possible for the human body to survive a bailout at 17,000 miles per hour? To answer these questions, space agencies set up all manner of quizzical and startlingly bizarre space simulations. As Mary Roach discovers, it's possible to preview space without ever leaving Earth. From the space shuttle training toilet to a crash test of NASA's new space capsule (cadaver filling in for astronaut), Roach takes us on a surreally entertaining trip into the science of life in space and space on Earth.
Our sun is one star among 50 billion in the galaxy. Our galaxy is only one among 50 billion in the universe. With a vastness this incomprehensible, it is easy to feel like we are mere specks of sand on an endless shore. But our sun is special. Though roughly 150 million kilometers separate us, we could not be more connected. Literally, everything you see comes from the sun. The words you are reading now are really photons that left the sun about 8 minutes ago only to bounce off this page and into your eyes. We owe our very existence to our sun. It provides just enough heat to keep our fragile bodies from freezing to ice or burning to a crisp. Every bite of food we eat we owe to the sun, whose energy is converted into plants that provide sustenance for everything up the food chain.
We have understood the sun's importance for millennia. The earliest humans, awestruck by its blazing splendor, left drawings of the sun on cave walls. Nearly every civilization, no matter where it sprang up on the planet, has revered the sun. Myths about the sun were the basis of the earliest deities of ancient Sumerian, Hindu, Egyptian, Chinese, and Meso-American cultures. Before Apollo, the ancient Greeks worshiped the sun-god Helios. Before Zeus, the ancient Romans worshiped Sol.
Throughout our history, the sun has been central to humanity's quest for meaning in the universe. But our history has been a brief moment in our sun's 4.5 billion year life. Only recently, through advances in science and technology, have we begun to understand our sun - where it came from, how it functions, how it affects our lives and how it eventually will destroy our planet.
Our Sun is a comprehensive, easy-to-understand guide to everything we know about our closest star. Illustrated with stunning pictures from NASA's newly-launched Solar Dynamics Observatory, Our Sun will reveal the science behind the sun, trace its impact on human history, and reveal its growing importance to our future way of life.
From "America's nerviest journalist" (Newsweek)--a breath-taking epic, a magnificent adventure story, and an investigation into the true heroism and courage of the first Americans to conquer space. "Tom Wolfe at his very best" (The New York Times Book Review)
Millions of words have poured forth about man's trip to the moon, but until now few people have had a sense of the most engrossing side of the adventure; namely, what went on in the minds of the astronauts themselves - in space, on the moon, and even during certain odysseys on earth. It is this, the inner life of the astronauts, that Tom Wolfe describes with his almost uncanny empathetic powers, that made The Right Stuff a classic.
Interstellar, from acclaimed filmmaker Christopher Nolan, takes us on a fantastic voyage far beyond our solar system. Yet in The Science of Interstellar, Kip Thorne, the Nobel prize-winning physicist who assisted Nolan on the scientific aspects of Interstellar, shows us that the movie's jaw-dropping events and stunning, never-before-attempted visuals are grounded in real science. Thorne shares his experiences working as the science adviser on the film and then moves on to the science itself. In chapters on wormholes, black holes, interstellar travel, and much more, Thorne's scientific insights--many of them triggered during the actual scripting and shooting of Interstellar--describe the physical laws that govern our universe and the truly astounding phenomena that those laws make possible.

From a leading planetary scientist and an award-winning science writer, a propulsive account of the developments and initiatives that have transformed the dream of space colonization into something that may well be achievable.We are at the cusp of a golden age in space science, as increasingly more entrepreneurs--Elon Musk, Richard Branson, Jeff Bezos--are seduced by the commercial potential of human access to space. But Beyond Earth does not offer another wide-eyed technology fantasy: instead, it is grounded not only in the human capacity for invention and the appeal of adventure but also in the bureaucratic, political, and scientific realities that present obstacles to space travel--realities that have hampered NASA's efforts ever since the Challenger disaster. In Beyond Earth, Charles Wohlforth and Amanda R.Hendrix offer groundbreaking research and argue persuasively that not Mars, but Titan--a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy, where we will even be able to fly like birds in the minimal gravitational field--offers the most realistic and thrill-ing prospect of life without support from Earth.
