This book presents the most serious and comprehensive study, by far, of American public perceptions about the meaning of space exploration, analyzing vast troves of questionnaire data collected by many researchers and polling firms over a span of six decades and anchored in influential social science theories. It doesn't simply report the percentages who held various opinions, but employs sophisticated statistical techniques to answer profound questions and achieve fresh discoveries.

The book opens with a discussion of the vorticity-dynamic formulation of the low Mach number viscous flow problem. Physical aspects of the velocity and the vorticity fields, their instantaneous relationship, and the transport of vorticity in viscous fluids are examined for steady and unsteady flows. Subsequently, the mathematical aspects of vorticity dynamics and issues of initial and boundary conditions for the viscous flow problem are treated rigorously using classical analyses. Coverage includes evolution of the vorticity field which surrounds and trails behind airfoils and wings,...

Interesting and often unexpected achievements of the mechanics of space flight throw a new light onto several classical problems. The book's emphasis is on analysis carried out on the level of graphs and drawings, and sometimes numbers, revealing the beauty of the research process leading to the results.

This contributed monograph is the first work to present the latest results and findings on the new topic and hot field of planetary exploration and sciences, e.g., lunar surface iron content and mare orientale basalts, Earth s gravity field, Martian radar exploration, crater recognition, ionosphere and astrobiology, Comet ionosphere, exoplanetary atmospheres and planet formation in binaries. By providing detailed theory and examples, this book helps readers to quickly familiarize themselves with the field. In addition, it offers a special section on next-generation planetary exploration,...

JAXA's Kaguya mission was successfully launched to the Moon on September 14, 2007 reaching its nominal 100 km circular orbit on October 19 after releasing two subsatellites Okina and Ouna in elliptical orbits with perilunes of 100 km and apolunes of 2400 and 800 km respectively. Observations were obtained for 10 months during the nominal mission beginning in mid-December 2007 followed by 8 month extended mission where data were obtained in lower orbits.

The articles in this book were written by experts in each of the scientific areas of the Kaguya mission, and describe both the...
