Book Description
J.L. Burch·V. 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.

Book Description
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

Book Description
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.

Book Description
Pacific Rim meets The Martian in the explosive follow-up to Sleeping Giants (“One of the most promising series kickoffs in recent memory.”—NPR) and Waking Gods (“Pure, unadulterated literary escapism.”—Kirkus Reviews). Brilliant scientist Rose Franklin has devoted her adult life to solving the mystery she accidentally stumbled upon as a child: a huge metal hand buried beneath the ground outside Deadwood, South Dakota. The discovery set in motion a cataclysmic chain of events with geopolitical ramifications. Rose and the Earth Defense Corps raced to master the enigmatic technology, as giant robots suddenly descended on Earth’s most populous cities, killing one hundred million people in the process. Though Rose and her team were able to fend off the attack, their victory was short-lived. The mysterious invaders retreated, disappearing from the shattered planet . . . but they took the scientist and her crew with them. Now, after nearly ten years on another world, Rose returns to find a devastating new war—this time between humans. America and Russia are locked in combat, fighting to fill the power vacuum left behind after the invasion. Families are torn apart, friends become bitter enemies, and countries collapse in the wake of the battling superpowers. It appears the aliens left behind their titanic death machines so humankind will obliterate itself. Rose is determined to find a solution, whatever it takes. But will she become a pawn in a doomsday game no one can win? Praise for Only Human “Packing a surprisingly powerful thematic punch, this novel is an addictive blend of science fiction, apocalyptic thriller, and chillingly timely cautionary tale. Two (giant, robotic) thumbs up!”—Kirkus Reviews “Boasting a winning combination of briskly paced action and futuristic dystopia tempered by cautious optimism, Only Human brings a fitting, satisfying end to the Themis Files series.”—RT Book Reviews “This action-packed tale with apocalyptic stakes is a fitting finale to this wonderfully cinematic series.”—Publishers Weekly “Series fans will be eager for Neuvel’s ever-so-satisfying conclusion to his rip-roaring science-fiction adventure tale.”—Booklist Don’t miss any of The Themis Files by Sylvain Neuvel: SLEEPING GIANTS | WAKING GODS | ONLY HUMAN

Book Description
In recent years, planetary science has seen a tremendous growth in new knowledge. Deposits of water ice exist at the Moon's poles. Discoveries on the surface of Mars point to an early warm wet climate, and perhaps conditions under which life could have emerged. Liquid methane rain falls on Saturn's moon Titan, creating rivers, lakes, and geologic landscapes with uncanny resemblances to Earth's. Vision and Voyages for Planetary Science in the Decade 2013-2022 surveys the current state of knowledge of the solar system and recommends a suite of planetary science flagship missions for the decade 2013-2022 that could provide a steady stream of important new discoveries about the solar system. Research priorities defined in the report were selected through a rigorous review that included input from five expert panels. NASA's highest priority large mission should be the Mars Astrobiology Explorer Cacher (MAX-C), a mission to Mars that could help determine whether the planet ever supported life and could also help answer questions about its geologic and climatic history. Other projects should include a mission to Jupiter's icy moon Europa and its subsurface ocean, and the Uranus Orbiter and Probe mission to investigate that planet's interior structure, atmosphere, and composition. For medium-size missions, Vision and Voyages for Planetary Science in the Decade 2013-2022 recommends that NASA select two new missions to be included in its New Frontiers program, which explores the solar system with frequent, mid-size spacecraft missions. If NASA cannot stay within budget for any of these proposed flagship projects, it should focus on smaller, less expensive missions first. Vision and Voyages for Planetary Science in the Decade 2013-2022 suggests that the National Science Foundation expand its funding for existing laboratories and establish new facilities as needed. It also recommends that the program enlist the participation of international partners. This report is a vital resource for government agencies supporting space science, the planetary science community, and the public.

Book Description
This open access book provides a comprehensive toolbox of analysis techniques for ionospheric multi-satellite missions. The immediate need for this volume was motivated by the ongoing ESA Swarm satellite mission, but the tools that are described are general and can be used for any future ionospheric multi-satellite mission with comparable instrumentation. In addition to researching the immediate plasma environment and its coupling to other regions, such a mission aims to study the Earth’s main magnetic field and its anomalies caused by core, mantle, or crustal sources. The parameters for carrying out this kind of work are examined in these chapters. Besides currents, electric fields, and plasma convection, these parameters include ionospheric conductance, Joule heating, neutral gas densities, and neutral winds.

Book Description
Principal Investigator-Led (PI-led) missions are an important element of NASA's space science enterprise. While several NRC studies have considered aspects of PI-led missions in the course of other studies for NASA, issues facing the PI-led missions in general have not been subject to much analysis in those studies. Nevertheless, these issues are raising increasingly important questions for NASA, and it requested the NRC to explore them as they currently affect PI-led missions. Among the issues NASA asked to have examined were those concerning cost and scheduling, the selection process, relationships among PI-led team members, and opportunities for knowledge transfer to new PIs. This report provides a discussion of the evolution and current status of the PIled mission concept, the ways in which certain practices have affected its performance, and the steps that can carry it successfully into the future. The study was done in collaboration with the National Academy of Public Administration.
