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.

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.

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.

"This stellar debut novel ... masterfully blends together elements of sci-fi, political thriller and apocalyptic fiction." -Kirkus Reviews. The Themis Files is a deeply human story about a world-changing alien discovery. 17 years ago, a young girl named Rose fell through the ground in the Black Hills and found herself in an underground chamber filled with gleaming symbols, lying in the palm of a giant metal hand. Now a physicist, Rose leads a research team struggling to determine the hand's origins. When another giant limb is discovered, Rose quickly devises a method for unearthing the hidden pieces, convinced there is an entire body out there waiting to be found. Halfway around the globe, Kara watches helplessly as her helicopter shuts down over a pistachio field in Turkey. That'll leave a mark, but she's about to crash her way into what might be the greatest endeavor in human history. This is a hunt for truth, power, and giant body parts. Written as a series of interview transcripts, journal entries and mission logs, The Themis Files tells the tale of a handful of people whose lives are inexorably linked by the discovery of an alien device and the commotion that follows.

This volume contains five articles describing the mission and its instruments. The first paper, by the project scientist Richard C. Elphic and his colleagues, describes the mission objectives, the launch vehicle, spacecraft and the mission itself. This is followed by a description of LADEE’s Neutral Mass Spectrometer by Paul Mahaffy and company. This paper describes the investigation that directly targets the lunar exosphere, which can also be explored optically in the ultraviolet. In the following article Anthony Colaprete describes LADEE’s Ultraviolet and Visible Spectrometer that operated from 230 nm to 810 nm scanning the atmosphere just above the surface. Not only is there atmosphere but there is also dust that putatively can be levitated above the surface, possibly by electric fields on the Moon’s surface. Mihaly Horanyi leads this investigation, called the Lunar Dust Experiment, aimed at understanding the purported observations of levitated dust. This experiment was also very successful, but in this case their discovery was not the electrostatic levitation of dust, but that the dust was raised by meteoroid impacts. This is not what had been expected but clearly is the explanation that best fits the data. Originally published in Space Science Reviews, Volume 185, Issue 1-4, 2014.

**A must-read thriller for lovers of The Passage, World War Z, The Martian or Interstellar** What happens when you make a discovery that changes everything? Deadwood, USA. A girl sneaks out just before dark to ride her new bike. Suddenly, the ground disappears beneath her. Waking up at the bottom of a deep pit, she sees an emergency rescue team above her. The people looking down see something far stranger... "We always look forward. We never look back." That girl grows up to be Dr. Rose Franklyn, a brilliant scientist and the leading world expert on what she discovered. An enormous, ornate hand made of an exceptionally rare metal, which predates all human civilisation on the continent. "But this thing ... it's different. It challenges us. It rewrites history." An object whose origins and purpose are perhaps the greatest mystery humanity has ever faced. Solving the secret of where it came from - and how many more parts may be out there - could change life as we know it. "It dares us to question what we know about ourselves." But what if we were meant to find it? And what happens when this vast, global puzzle is complete...? "About everything." * * * 'Bursts at the seams with big ideas. A sheer blast from start to finish. I haven't had this much fun reading in ages' Blake Crouch, author of the Wayward Pines trilogy 'A stellar debut which masterfully blends sci-fi, political thriller and apocalyptic fiction. So much more than the sum of its parts - a page-turner of the highest order' Kirkus Reviews 'Reminiscent of The Martian and World War Z, this is a luminous conspiracy yarn that shoots for (and lands among) the stars' Pierce Brown, author of Red Rising

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.
