Wharton professor Richard Shell created the Success Course to help his world-class MBA students answer two questions that aren’t as obvious as they seem: “What, for me, is success?” and “How will I achieve it?” Based on that acclaimed course, Springboard shows how to assess the hidden influences of family, media, and culture on your beliefs about success. Then it helps you figure out your unique passions and capabilities, so you can focus more on what gives meaning and excitement to your life, and less on what you are “supposed” to want.
This is the second volume in a series of chronological histories prepared by the Marine Corps History and Museums Division to cover the entire span of Marine Corps involvement in the Vietnam War. This volume details the Marine activities during 1965, the year the war escalated and major American combat units were committed to the conflict. The narrative traces the landing of the nearly 5,000-man 9th Marine Expeditionary Brigade and its transformation into the ΙII Marine Amphibious Force, which by the end of the year contained over 38,000 Marines. During this period, the Marines established three enclaves in South Vietnam’s northernmost corps area, I Corps, and their mission expanded from defense of the Da Nang Airbase to a balanced strategy involving base defense, offensive operations, and pacification. This volume continues to treat the activities of Marine advisors to the South Vietnamese armed forces but in less detail than its predecessor volume, U.S. Marines in Vietnam, 1954-1964; The Advisory and Combat Assistance Era.
Volume 60 of Reviews in Mineralogy and Geochemistry assesses the current state of knowledge of lunar geoscience, given the data sets provided by missions of the 1990's, and lists remaining key questions as well as new ones for future exploration to address. It documents how a planet or moon other than the world on which we live can be studied and understood in light of integrated suites of specific kinds of information. The Moon is the only body other than Earth for which we have material samples of known geologic context for study. This volume seeks to show how the different kinds of information gained about the Moon relate to each other and also to learn from this experience, thus allowing more efficient planning for the exploration of other worlds.
Popular Science gives our readers the information and tools to improve their technology and their world. The core belief that Popular Science and our readers share: The future is going to be better, and science and technology are the driving forces that will help make it better.

Orbital Mechanics for Engineering Students, Second Edition, provides an introduction to the basic concepts of space mechanics. These include vector kinematics in three dimensions; Newton's laws of motion and gravitation; relative motion; the vector-based solution of the classical two-body problem; derivation of Kepler's equations; orbits in three dimensions; preliminary orbit determination; and orbital maneuvers. The book also covers relative motion and the two-impulse rendezvous problem; interplanetary mission design using patched conics; rigid-body dynamics used to characterize the attitude of a space vehicle; satellite attitude dynamics; and the characteristics and design of multi-stage launch vehicles. Each chapter begins with an outline of key concepts and concludes with problems that are based on the material covered. This text is written for undergraduates who are studying orbital mechanics for the first time and have completed courses in physics, dynamics, and mathematics, including differential equations and applied linear algebra. Graduate students, researchers, and experienced practitioners will also find useful review materials in the book. - NEW: Reorganized and improved discusions of coordinate systems, new discussion on perturbations and quarternions - NEW: Increased coverage of attitude dynamics, including new Matlab algorithms and examples in chapter 10 - New examples and homework problems
For centuries humankind has fantasized about life on Mars, whether it’s intelligent Martian life invading our planet (immortalized in H.G. Wells’s The War of the Worlds) or humanity colonizing Mars (the late Ray Bradbury’s The Martian Chronicles). The Red Planet’s proximity and likeness to Earth make it a magnet for our collective imagination. Yet the question of whether life exists on Mars—or has ever existed there—remains an open one. Science has not caught up to science fiction—at least not yet. This summer we will be one step closer to finding the answer. On August 5th, Curiosity—a one-ton, Mini Cooper-sized nuclear-powered rover—is scheduled to land on Mars, with the primary mission of determining whether the red planet has ever been physically capable of supporting life. In Getting to Mars, Roger Wiens, the principal investigator for the ChemCam instrument on the rover—the main tool for measuring Mars’s past habitability—will tell the unlikely story of the development of this payload and rover now blasting towards a planet 354 million miles from Earth. ChemCam (short for Chemistry and Camera) is an instrument onboard the Curiosity designed to vaporize and measure the chemical makeup of Martian rocks. Different elements give off uniquely colored light when zapped with a laser; the light is then read by the instrument’s spectrometer and identified. The idea is to use ChemCam to detect life-supporting elements such as carbon, nitrogen, and oxygen to evaluate whether conditions on Mars have ever been favorable for microbial life. This is not only an inside story about sending fantastic lasers to Mars, however. It’s the story of a new era in space exploration. Starting with NASA’s introduction of the Discovery Program in 1992, smaller, scrappier, more nimble missions won out as behemoth manned projects went extinct. This strategic shift presented huge opportunities—but also presented huge risks for shutdown and failure. And as Wiens recounts, his project came close to being closed down on numerous occasions. Getting to Mars is the inspiring account of how Wiens and his team overcame incredible challenges—logistical, financial, and political—to successfully launch a rover in an effort to answer the eternal question: is there life on Mars?
