Angelopoulos Originally published in the journal Space Science Reviews, Volume 141, Nos 1–4, 1–3. DOI: 10.1007/s11214-008-9474-5 © Springer Science+Business Media B.V. 2008 The Earth, like all the other planets, is continuously bombarded by the solar wind, which is variable on many time scales owing to its connection to the activity of the Sun. But the Earth is unique among planets because its atmosphere, magnetic eld, and rotation rates are each signi cant, though not dominant, players in the formation of its magnetosphere and its reaction to solar-wind inputs. An intriguing fact is that no matter what the time scale of solar-wind variations, the Earth’s response has a de nite pattern lasting a few hours. Known as a magnetospheric substorm, the response involves a build-up, a crash, and a recovery. The build-up (known as the growth phase) occurs because of an interlinking of the geom- netic eld and the solar-wind magnetic eld known as magnetic reconnection, which leads to storage of increasing amounts of magnetic energy and stress in the tail of the mag- tosphere and lasts about a half hour. The crash (known as the expansion phase) occurs when the increased magnetic energy and stresses are impulsively relieved, the current system that supports the stretched out magnetic tail is diverted into the ionosphere, and bright, dynamic displays of the aurora appear in the upper atmosphere. The expansion and subsequent rec- ery phases result from a second magnetic reconnection event that decouples the solar-wind and geomagnetic elds.

Download and read online ebook The ARTEMIS Mission write by Christopher Russell. This book was released on 2013-11-18. The ARTEMIS Mission available in PDF, EPUB and Kindle. The ARTEMIS mission was initiated by skillfully moving the two outermost Earth-orbiting THEMIS spacecraft into lunar orbit to conduct unprecedented dual spacecraft observations of the lunar environment. ARTEMIS stands for Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon's Interaction with the Sun. Indeed, this volume discusses initial findings related to the Moon’s magnetic and plasma environments and the electrical conductivity of the lunar interior. This work is aimed at researchers and graduate students in both heliophysics and planetary physics. Originally published in Space Science Reviews, Vol. 165/1-4, 2011.

This book was released on 2017-04-04. Waking Gods available in PDF, EPUB and Kindle. In the gripping sequel to Sleeping Giants, Sylvain Neuvel’s innovative series about human-alien contact takes another giant step forward. “Sleeping Giants may have debuted his thrilling saga, but Waking Gods proves that Neuvel’s scope is more daring than readers could have imagined.”—Paste As a child, Rose Franklin made an astonishing discovery: a giant metallic hand, buried deep within the earth. As an adult, she’s dedicated her brilliant scientific career to solving the mystery that began that fateful day: Why was a titanic robot of unknown origin buried in pieces around the world? Years of investigation have produced intriguing answers—and even more perplexing questions. But the truth is closer than ever before when a second robot, more massive than the first, materializes and lashes out with deadly force. Now humankind faces a nightmare invasion scenario made real, as more colossal machines touch down across the globe. But Rose and her team at the Earth Defense Corps refuse to surrender. They can turn the tide if they can unlock the last secrets of an advanced alien technology. The greatest weapon humanity wields is knowledge in a do-or-die battle to inherit the Earth . . . and maybe even the stars. Praise for Waking Gods “Kick-ass, one-on-one robot action combines with mind-bending scientific and philosophical speculation. Series science-fiction fans will enjoy this follow-up filled with unexpected revelations and a surprise finale.”—Booklist “Pure, unadulterated literary escapism featuring giant killer robots and the looming end of mankind. In a word: unputdownable.”—Kirkus Reviews (starred review) “Sheer escapist fun.”—Shelf Awareness Don’t miss any of The Themis Files by Sylvain Neuvel: SLEEPING GIANTS | WAKING GODS | ONLY HUMAN

Download and read online ebook Measurement Techniques in Space Plasmas write by Robert F. Pfaff. This book was released on 1998-02-04. Measurement Techniques in Space Plasmas available in PDF, EPUB and Kindle. Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 102. Space plasma measurements are conducted in a hostile, remote environment. The art and science of measurements gathered in space depend therefore on unique instrument designs and fabrication methods to an extent perhaps unprecedented in experimental physics. In-situ measurement of space plasmas constitutes an expensive, unforgiving, and highly visible form of scientific endeavor.

Download and read online ebook The Dawn Mission to Minor Planets 4 Vesta and 1 Ceres write by Christopher Russell. This book was released on 2012-07-27. The Dawn Mission to Minor Planets 4 Vesta and 1 Ceres available in PDF, EPUB and Kindle. Dawn is the first mission to orbit a main belt asteroid and the first scientific mission to use ion propulsion. Major objectives of this mission include mapping of the surfaces of 4 Vesta and 1 Ceres, determining its topography from stereo measurements, determining its mineralogy, measuring its elemental composition and obtaining gravity data. This book describes the Dawn mission, its exploration and scientific objectives, the instruments that accomplish those objectives, the operations plan and the education and outreach plan. It is directed to those studying asteroids and the evolution of the solar system. This volume will be a valuable reference for anyone who uses data from the instruments of the DAWN mission. Previously published in Space Science Reviews, Vol. 163/1-4, 2012.
