Since the earliest days of spaceflight, substantial concern has been expressed regarding the physical needs of astronauts, including any biological damage that might result from exposure to radiation or from reduction in gravitational forces.

Book Description
The incredible, untold story behind the rise of the P-51 Mustang, the World War II fighter plane that destroyed the Luftwaffe and made D-Day possible “Aviation buffs will cheer this high-flying saga.”—Publishers Weekly • “[A] fascinating book about passion and innovation.”—Walter Isaacson • “An essential book for those who appreciate tales of military bravery, and also for all seeking understanding of decision-making under pressure. A major contribution.”—E. J. Dionne, Jr. When the P-51 Mustang began tearing across European skies in early 1944, the Allies had been losing the air war for years. Staggering numbers of bomber crews, both British and American, had been shot down and killed thanks to the Luftwaffe’s superior fighter force. Not only did the air war appear grim, but any landing of troops in France was impossible while German fighters hunted overhead. But behind the scenes, a team of visionaries had begun to design a bold new type of airplane, one that could outrun and outmaneuver Germany’s best. Wings of War is the incredible true story of the P-51 Mustang fighter and the unlikely crew of designers, engineers, test pilots, and army officers who brought it from the drafting table to the skies over World War II. This is hardly a straightforward tale of building an airplane—for years, the team was stymied by corruption within the defense industry and stonewalled by the Army Air Forces, who failed to understand the Mustang’s potential. But when squadrons of Mustangs were finally unleashed over Hitler’s empire, the Luftwaffe was decimated within months, clearing the skies for D-Day. A compelling, character-focused narrative replete with innovation, determination, and bravery, Wings of War is the never-before-told story of the airplane that truly changed the course of World War II.

Book Description
Directed Energy Weapons is nothing new to mankind, historically the origination of such weapons falls in centuries ago when first time the famous Greek mathematician, physicist, engineer, inventor, and astronomer Archimedes of Syracuse used different mirrors to collect sunbeams and focusing them on Romans fleet in order to destroy enemy ships with fire. This is known as the Archimedes Heat Ray. Archimedes may have used mirrors acting collectively as a parabolic reflector to burn ships attacking Syracuse. The device was used to focus sunlight onto approaching ships, causing them to catch fire. Of course the myth or reality of Archimedes Heat Ray still is a questionable story, but certain experiments with the help of a group of students from Massachusetts Institute of Technology was carried out with 127 one-foot (30 cm) square mirror tiles in October of 2005 that was focused on a mock-up wooden ship at a range of around 100 feet (30 m). The flames broke out on a patch of the ship, but only after the sky had been cloudless and the ship had remained stationary for around ten minutes. It was concluded the device was a feasible weapon under these conditions.

Book Description
This paper is an outgrowth of comments I heard and attitudes I experienced at the JFCOM Joint Space Concept Development and Experimentation Workshop in Norfolk at the end of March 2004. I presented a briefing on near-space at the conference along with colleagues from JFCOM, the Army Space and Missile Defense Battlelab, the Naval Research Laboratory, and the Navy Warfare Development Command. It discussed how many functions that are currently done with satellites could be performed for tactical and operational commanders using near-space assets much more cheaply and with much greater operational utility. The briefing was very well received with nothing but positive comments all around. However, once we broke into focus groups trying to develop exercise inputs for such subjects as operationally responsive space, the near-space concept was almost forgotten. It didn't fit into the normal mindset of what space meant, so it was difficult to convince other group members that it should be discussed in the same breath as, say, a TacSat-type program. After much thought, it was my perception that the problem was one of mindset as to what the word "space" meant to the warfighter. After reading space doctrine (Army, Navy, Air Force, and Joint), I discovered that the mindset I sensed at the workshop had actually been codified to define space as a place where we operate satellites. That mindset is counterproductive.

Book Description
Our knowledge of breathing has shaped our social history and philosophical beliefs since prehistory. Breathing occupied a spiritual status for the ancients, while today it is central to the practice of many forms of meditation, like Yoga. Over time physicians, scientists, and engineers have pieced together the intricate biological mechanisms of breathing to devise ever more sophisticated devices to support and maintain breathing indefinitely, from iron lungs to the modern ventilator. Breathing supplementary oxygen has allowed us to conquer Everest, travel to the Moon, and dive to ever greater ocean depths. We all expect to breathe fresh and clean air, but with an increase in air pollution that expectation is no longer being met. Today, respiratory viruses like COVID-19 are causing disasters both human and economical on a global scale. This is the story of breathing—a tale relevant to everyone.

Book Description
"Amateur weather forecasters (which includes just about everyone) will find this volume an informative and entertaining account of the why and how of the weather." — The Nation In simple language, Eric Sloane explains the whys and wherefores of weather and weather forecasting — and does it in a style that's universally appealing. With humor and common sense shining through in a book that's also lively and informative, Sloane shows readers how to predict the weather by "reading" such natural phenomena as winds, skies, and animal sounds. This beautifully illustrated and practical treasure trove of climate lore will enlighten outdoorsmen, farmers, sailors, and anyone else who has ever wondered what a large halo around the moon means, why birds "sit it out" before a storm, and whether or not to take an umbrella when leaving the house.
