In the last thirty years humans have probed the Universe, explored the Solar System and visited with spacecraft some of the most incredible places humans have ever laid eyes upon. We have expanded our knowledge slowly and surely, but still now only see a glimpse of the bigger picture. The Cosmic Keyhole explores the big discoveries of recent years and asks what’s next? How prolific is life in the Universe? How far back to the Big Bang can we probe?... more...

A concise but thorough introduction to the observational data and theoretical concepts underlying modern astronomy, Astrophysics in a Nutshell is designed for advanced undergraduate science majors taking a one-semester course. This well-balanced and up-to-date textbook covers the essentials of modern astrophysics--from stars to cosmology--emphasizing the common, familiar physical principles that govern astronomical phenomena, and the interplay between... more...


Modern Cosmology begins with an introduction to the smooth, homogeneous universe described by a Friedman-Robertson-Walker metric, including careful treatments of dark energy, big bang nucleosynthesis, recombination, and dark matter. From this starting point, the reader is introduced to perturbations about an FRW universe: their evolution with the Einstein-Boltzmann equations, their generation by primordial inflation, and their observational... more...

Grappling with Gravity explores the physiological changes that will occur in humans and the plants and animals that accompany humans as we move to new worlds, be it to colony in the emptiness of space or settlements on the Moon, Mars, or other moons or planets. This book focuses on the biomedical aspects, while not ignoring other life-changing influences of space living. For example, what happens to people physiologically in the microgravity of space,... more...


Supersymmetry is at an exciting stage of development. It extends the Standard Model of particle physics into a more powerful theory that both explains more and allows more questions to be addressed. Most importantly, it opens a window for studying and testing fundamental theories at the Planck scale. Experimentally we are finally entering the intensity and energy and sensitivity regions where superpartners and supersymmetric dark matter candidates are... more...

For decades, astronomers have sought to discover the ultimate fate of the univers. Will the cosmos continue forever in its expansion, which began billions of years ago with the big bang? Or will gravity someday reverse the process, producing a "big crunch?" Within the past few years, two rival groups of astronomers have announced a discovery that seems to resolve the issue: Instead of slowing down, the expansion of the universe seems to be... more...

In the Shadow of the Moon tells the story of the most exciting and challenging years in spaceflight, with two superpowers engaged in a titanic struggle to land one of their own people on the moon. Drawing on interviews with astronauts, cosmonauts, their families, technicians, and scientists, as well as rarely seen Soviet and American government documents, the authors craft a remarkable story of the golden age of spaceflight as both an intimate human... more...

NASA's Office of the Chief Technologist (OCT) has begun to rebuild the advanced space technology program in the agency with plans laid out in 14 draft technology roadmaps. It has been years since NASA has had a vigorous, broad-based program in advanced space technology development and its technology base has been largely depleted. However, success in executing future NASA space missions will depend on advanced technology developments that should... more...

In the five decades since NASA was created, the agency has sustained its legacy from the National Advisory Committee on Aeronautics (NACA) in playing a major role in U.S. aeronautics research and has contributed substantially to United States preeminence in civil and military aviation. This preeminence has contributed significantly to the overall economy and balance of trade of the United States through the sales of aircraft throughout the world.... more...
