This book explores the practicality of using the existing subsurface geology on the Moon and Mars for protection against radiation, thermal extremes, micrometeorites and dust storms rather than building surface habitats at great expense at least for those first few missions. It encourages NASA to plan a precursor mission using this concept and employ a “Short Stay” Opposition Class mission to Mars as the first mission rather than the “Long Stay” concept requiring a mission that is too long, too dangerous and too costly for man’s first missions to Mars. Included in these pages is a short history on the uses of caves by early humans over great periods of time. It then describes the ongoing efforts to research caves, pits, tunnels, lava tubes, skylights and the associated technologies that pertain to potential lunar and Mars exploration and habitation. It describes evidence for existing caves and lava tubes on both the Moon and Mars. The work of noted scientists, technologists and roboticists are referenced and described. This ongoing work is moreextensive than one would think and is directly applicable to longer term habitation and exploration of the Moon and Mars. Emphasis is also given to the operational aspects of working and living in lunar and Martian caves and lava tubes.

Popular marriage counselor and seminar leader John Gray provides a unique, practical and proven way for men and women to communicate and relate better by acknowledging the differences between them. Once upon a time Martians and Venusians met, fell in love, and had happy relationships together because they respected and accepted their differences. Then they came to earth and amnesia set in: they forgot they were from different planets. Using this metaphor to illustrate the commonly occurring conflicts between men and women, Gray explains how these differences can come between the sexes and prohibit mutually fulfilling loving relationships. Based on years of successful counseling of couples, he gives advice on how to counteract these differences in communication styles, emotional needs and modes of behavior to promote a greater understanding between individual partners. Gray shows how men and women react differently in conversation and how their relationships are affected by male intimacy cycles ("get close", "back off"), and female self-esteem fluctuations ("I'm okay", "I'm not okay"). He encourages readers to accept the other gender's particular way of expressing love, and helps men and women learn how to fulfill each other's emotional needs. With practical suggestions on how to reduce conflict, crucial information on how to interpret a partner's behavior and methods for preventing emotional "trash from the past" from invading new relationships, Men Are from Mars, Women Are from Venus is a valuable tool for couples who want to develop deeper and more satisfying relationships with their partners.

The bestselling author who celebrated gender differences turns to diet and exercise as a source of well-being and harmony.

The author tells of adventures that include New Mexico's Lechuguilla Cave and dark life below Washington State that resembles "micro-fossils" found in a Martian meteorite.

Meet NASA inventor Penny Boston! She's here to introduce readers to Martian cave colonies. Alongside Penny, readers will learn about astrobiology and the possibilities of living in caves on Mars. They'll explore caves throughout the solar system, microbes, inflatable cave liners, bioreactors, and oxygen. The Inventor Challenge at the back of the book encourages readers to create their own inventions.

* THE INSTANT NEW YORK TIMES BESTSELLER * Scientific American’s #1 Book for 2023 * A New York Times Book Review Editors' Choice * A Times Best Science and Environment Book of 2023 * “Exceptional. . . Forceful, engaging and funny . . . This book will make you happy to live on this planet — a good thing, because you’re not leaving anytime soon.” —New York Times Book Review From the bestselling authors of Soonish, a brilliant and hilarious off-world investigation into space settlement Earth is not well. The promise of starting life anew somewhere far, far away—no climate change, no war, no Twitter—beckons, and settling the stars finally seems within our grasp. Or is it? Critically acclaimed, bestselling authors Kelly and Zach Weinersmith set out to write the essential guide to a glorious future of space settlements, but after years of research, they aren’t so sure it’s a good idea. Space technologies and space business are progressing fast, but we lack the knowledge needed to have space kids, build space farms, and create space nations in a way that doesn’t spark conflict back home. In a world hurtling toward human expansion into space, A City on Mars investigates whether the dream of new worlds won’t create nightmares, both for settlers and the people they leave behind. In the process, the Weinersmiths answer every question about space you’ve ever wondered about, and many you’ve never considered: Can you make babies in space? Should corporations govern space settlements? What about space war? Are we headed for a housing crisis on the Moon’s Peaks of Eternal Light—and what happens if you’re left in the Craters of Eternal Darkness? Why do astronauts love taco sauce? Speaking of meals, what’s the legal status of space cannibalism? With deep expertise, a winning sense of humor, and art from the beloved creator of Saturday Morning Breakfast Cereal, the Weinersmiths investigate perhaps the biggest questions humanity will ever ask itself—whether and how to become multiplanetary. Get in, we’re going to Mars.
