Facing the Heat Barrier: A History of HypersonicsThis volume from The NASA History Series presents an overview of the science of hypersonics, the study of flight at speeds at which the physics of flows is dominated by aerodynamic heating. The survey begins during the years immediately following World War II, with the first steps in hypersonic research: the development of missile nose cones and the X 15; the earliest concepts of hypersonic propulsion; and the origin of the scramjet engine.

This volume from The NASA History Series presents an overview of the science of hypersonics, the study of flight at speeds at which the physics of flows is dominated by aerodynamic heating. The survey begins during the years immediately following World War II, with the first steps in hypersonic research: the development of missile nose cones and the X-15; the earliest concepts of hypersonic propulsion; and the origin of the scramjet engine. Next, it addresses the re-entry problem, which came to the forefront during the mid-1950s, showing how work in this area supported the manned space program and contributed to the development of the orbital shuttle.Subsequent chapters explore the fading of scramjet studies and the rise of the National Aerospace Plane (NASP) program of 1985-95, which sought to lay groundwork for single-stage vehicles. The program's ultimate shortcomings -- in terms of aerodynamics, propulsion, and materials -- are discussed, and the book concludes with a look at hypersonics in the post-NASP era, including the development of the X-33 and X-34 launch vehicles, further uses for scramjets, and advances in fluid mechanics. Clearly, ongoing research in hypersonics has yet to reach its full potential, and readers with an interest in aeronautics and astronautics will find this book a fascinating exploration of the field's history and future.

Toxic ingredients
Size: 2 Fl Oz (Pack of 1)
There are endocrine disruptors in here that are harmful to your health. I nearly got to the point of being disabled from endocrine issues. Has ingredients that ruin fertility, raise risk of cancer, and ruin your endocrine system. I hope these brands can take these ingredients out and begin to care about consumers health.

Best Baby Sunscreen ☀️
Size: 6 Ounce (Pack of 2), Style: SPF 50 Spray
Putting sunscreen on a one year old is never an easy task. So I learned very quickly that the spray was a must. I’ve tried several different kinds and have had issues with eye irritation because I’m sure as y’all all know (that I definitely did not know) the first thing they do when you put sunscreen on their face is rub it immediately in their eyes. Although this one is not completely irritation free, I have noticed much less irritation to her eyes (or maybe she’s finally learning not to rub her eyes after I put it on idk 🤷🏼♀️). Regardless this is a great safe, easy to apply sunscreen for babies!
