Book Description
Travel to and from Mars has long been a staple of science fiction. And yet the hurdles--both technological and financial--have kept human exploration of the red planet from becoming a reality. Trailblazing Mars offers an inside look at the current efforts to fulfill this dream. Award-winning journalist Pat Duggins examines the extreme new challenges that will be faced by astronauts on the journey there and back. They'll have to grow their own food, find their own water, and solve their own problems and emergencies without hope of rescue or re-supply. Mars travel will be more challenging and hazardous than settling the Old West--but we were not witness to the fate of the Donner Party on CNN. Can the technological hurdles be cleared? Will the public accept the very real possibility of astronaut death? Should a mission be publicly or privately funded? Is the science worth the cost? These and many other questions are answered in Duggins's exciting new book.

Book Description
Since the beginning of human history Mars has been an alluring dream; the stuff of legends, gods, and mystery. The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit. Now with the advent of a revolutionary new plan, all this has changed. Leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with illustrations, photographs, and engaging anecdotes. The Case for Mars is not a vision for the far future or one that will cost us impossible billions. It explains step-by-step how we can use present-day technology to send humans to Mars within ten years; actually produce fuel and oxygen on the planet's surface with Martian natural resources; how we can build bases and settlements; and how we can one day "terraform" Mars; a process that can alter the atmosphere of planets and pave the way for sustainable life.

Book Description
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? And what hidden treasures still await us in the hidden corners of our Solar System?

Book Description
""The Red Planet"" takes readers on a captivating journey through our evolving understanding of Mars, from ancient observations to cutting-edge scientific discoveries. This comprehensive exploration delves into Mars' physical characteristics, the search for signs of life, and the potential for human colonization. The book argues that Mars represents both a scientific treasure trove and a possible second home for humanity, emphasizing the importance of continued exploration for advancing our knowledge of planetary science and the origins of life. Structured to guide readers through increasingly complex topics, the book begins with Mars' basic characteristics before examining its geology, including massive volcanoes and polar ice caps. It then explores evidence of past water on Mars, such as dry riverbeds and mineral deposits, which point to a potentially more habitable past. The search for life on Mars forms a crucial section, discussing the requirements for life as we know it and how Mars may have met these conditions. The book concludes by exploring the challenges and ethical considerations of human colonization on the Red Planet. Drawing on a wide range of evidence from satellites, rovers, and Earth-based studies, ""The Red Planet"" balances scientific rigor with engaging narratives about the people and missions shaping our knowledge of Mars. Written in an accessible yet authoritative style, it offers practical insights for readers interested in Mars exploration, including how to observe Mars from Earth and understand news about ongoing missions.

He has experienced more than one hundred sightings of the shadow people, or black ghosts. He credits guardian angels with saving him from harm or certain death on a number of occasions. Hawkeswood also shares accounts of his numerous sightings of strange aerial phenomena he believes were caused by UFOs. He has personally experienced clairaudiencevoices from beyondand precognition, or the ability to see the future. His detailed account of a unique out-of-body experience (OOBE) challenges what is known about this remarkable ability.

At eighteen, he survived a terrifying encounter with a demon gargoyle who tried to steal his soul energy after paralysing him. A comprehensive handbook for the paranormal enthusiast, Hawkeswoods work also provides a glossary and reference list of English-language UFO books.

Book Description
The Atomic Space Age has been and continues to be an engine for future wealth creation. Humanity stands on the verge of becoming an interplanetary species. We know we are made of star-stuff precisely because many of the isotopes in our bodies originated in the death throes of dying suns. With the discovery of nuclear fission in 1938, mankind was for the first time able to glimpse both our distant past and our possible future. As with the discovery of fire and agriculture thousands of years ago, wind power hundreds of years ago, and steam power and electricity in the nineteenth century, we must now learn to tame this powerful new force locked within the heart of the atom. Buckminster Fuller once observed that wealth is nothing more than energy compounded by ingenuity. Since (mass-)energy can never decrease, and ingenuity will only increase, there is no limit to the quantity of wealth that our species can and will create using nuclear space propulsion.
