Pathways to Exploration: Rationales and Approaches for a U.S. Program of Human Space Exploration

The United States has publicly funded its human spaceflight program on a continuous basis for more than a half-century, through three wars and a half-dozen recessions, from the early Mercury and Gemini suborbital and Earth orbital missions, to the lunar landings, and thence to the first reusable winged crewed spaceplane that the United States operated for three decades. Today the United States is

Alpha Centauri: Unveiling the Secrets of Our Nearest Stellar Neighbor

As our closest stellar companion and composed of two Sun-like stars and a third small dwarf star, Alpha Centauri is an ideal testing ground of astrophysical models and has played a central role in the history and development of modern astronomy–from the first guesses at stellar distances to understanding how our own star, the Sun, might have evolved. It is also the host of the nearest known exop

Rotorcraft Aeromechanics

A rotorcraft is a class of aircraft that uses large-diameter rotating wings to accomplish efficient vertical take-off and landing. The class encompasses helicopters of numerous configurations (single main rotor and tail rotor, tandem rotors, coaxial rotors), tilting proprotor aircraft, compound helicopters, and many other innovative configuration concepts. Aeromechanics includes much of what the r
