This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter, challenging some of the standard assumptions which may be true for some Dark Matter candidates but not for all. So, this can be seen either as an introduction to a specialized topic or an out-of-the-box introduction to the field of Dark Matter in general. No matter if you are a theoretical particle physicist, an observational astronomer, or a ground based experimentalist, no matter if you are a grad student or an active researcher, you can benefit from this text, for a simple reason: a non-standard candidate for Dark Matter can teach you a lot about what we truly know about our standard picture of how the Universe works.

The world will always remember Neil Armstrong and Buzz Aldrin for their first steps on the moon, yet few today hold in respect the sites that made these and other astronauts' journeys possible. Across the American landscape and on the lunar surface, many facilities and landing sites linked to the Apollo program remain unprotected. Some have already crumbled to ruins-silent and abandoned. The Final Mission explores these key locations, reframes the footprints and items left on the moon as cultural resources, and calls for the urgent preservation of this space heritage. Beginning with the initiation of the space race, the authors trace the history of research, training, and manufacturing centers that contributed to lunar exploration. From the early rocket test stands of Robert H. Goddard, to astronaut instruction at Meteor Crater, to human and primate experiments at Holloman Air Force Base, innumerable places proved critical to developing the equipment for exploring space, surviving the journey, and returning to Earth safely. Despite their significance to the history of human spaceflight, many landmarks face the threat of damage or destruction. Most alarming is that the rapid advancement of technology renders stations obsolete long before they are deemed worthy of preservation. Moreover, the lack of precedence for protecting off-planet artifacts poses a unique challenge for space archaeology. While NASA's 2011 recommendations for spacefarers suggest avoiding close proximity to this cultural landscape, the authors advocate stronger routes of preservation and present models for safeguarding space history-both on Earth's surface and beyond.

This manual takes a look at what we know about the 'red planet' that has fascinated man for centuries, and presents the next major challenge in the exploration of our solar system. From early telescopic observations through the dawn of the space age, do today's quest for life on Mars, using orbiters, landers and rovers, following the discovery of water ice below the planet's surface, this book explains the history of man's study and analysis of the planet, and how modern-day science has furthered out understanding of Mars.
