Book Description
Marvel at the wonders of the universe, from stars and planets to black holes and nebulae, in this exploration of our solar system and beyond. Universe opens with a look at astronomy and the history of the Universe, using 3D artworks to provide a comprehensive grounding in the fundamental concepts of astronomy, including the basic techniques of practical astronomy. The core of the book is a tour of the cosmos covering the Solar System, the Milky Way, and galaxies beyond our own. Explanatory pages introduce different celestial phenomena, such as galaxies, and are followed by catalogs that profile the most interesting and important examples. A comprehensive star atlas completes the picture, with entries on each of the 88 constellations and a monthly sky guide showing the night sky as it appears throughout the year as viewed from both the northern and southern hemispheres.

Book Description
The New York Times bestselling novel ZODIAC is the first book in a breathtaking sci-fi series inspired by astrology that will stun fans of The Illuminae Files and the Starbound trilogy. At the dawn of time, there were 13 Houses in the Zodiac Galaxy. Now only 12 remain.... Rhoma Grace is a 16-year-old student from House Cancer with an unusual way of reading the stars. While her classmates use measurements to make accurate astrological predictions, Rho can’t solve for ‘x’ to save her life—so instead, she looks up at the night sky and makes up stories. When a violent blast strikes the moons of Cancer, sending its ocean planet off-kilter and killing thousands of citizens—including its beloved Guardian—Rho is more surprised than anyone when she is named the House’s new leader. But, a true Cancrian who loves her home fiercely and will protect her people no matter what, Rho accepts. Then, when more Houses fall victim to freak weather catastrophes, Rho starts seeing a pattern in the stars. She suspects Ophiuchus—the exiled 13th Guardian of Zodiac legend—has returned to exact his revenge across the Galaxy. Now Rho—along with Hysan Dax, a young envoy from House Libra, and Mathias, her guide and a member of her Royal Guard—must travel through the Zodiac to warn the other Guardians. But who will believe anything this young novice says? Whom can Rho trust in a universe defined by differences? And how can she convince twelve worlds to unite as one Zodiac? Embark on a dazzling journey with ZODIAC, the first novel in an epic sci-fi-meets-high-fantasy series set in a galaxy inspired by the astrological signs.
Orbital Mechanics for Engineering Students
Author: Howard D. CurtisPublisher: Elsevier
ISBN: 0080887848
Category : Technology & Engineering
Languages : en
Pages : 740
Book Description
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
Deep Space Flight and Communications

Book Description
The majority of books dealing with prospects for interstellar flight tackle the problem of the propulsion systems that will be needed to send a craft on an interstellar trajectory. The proposed book looks at two other, equally important aspects of such space missions, and each forms half of this two part book. Part 1 looks at the ways in which it is possible to exploit the focusing effect of the Sun as a gravitational lens for scientific missions to distances of 550 AU and beyond into interstellar space. The author explains the mechanism of the Sun as a gravitational lens, the scientific investigations which may be carried out along the way to a distance of 550 AU (and at the 550 AU sphere itself), the requirements for exiting the Solar System at the highest speed and a range of project ideas for missions entering interstellar space. Part 2 of the book deals with the problems of communicating between an interstellar spaceship and the Earth, especially at very high speeds. Here the author assesses a range of mathematical tools relating to the Karhunen-Loève Transform (KLT) for optimal telecommunications, technical topics that may one day enable humans flying around the Galaxy to keep in contact with the Earth. This part of the book opens with a summary of the author’s 2003 Pešek Lecture presented at the IAC in Bremen, which introduces the concept of KLT for engineers and ‘newcomers’ to the subject. It is planned to include a DVD containing the full mathematical derivations of the KLT for those interested in this important mathematical tool whilst the text itself will contain the various results without outlines of the mathematical proofs. Astronautical engineers will thus be able to see the application of the results without getting bogged down in the mathematics.
