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 excerpt: 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

This book was released on 2012-01-30 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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 excerpt: **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

This book was released on 2017-01-29 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA operates a large number of space science missions, approximately three-quarters of which are currently in their extended operations phase. They represent not only a majority of operational space science missions, but a substantial national investment and vital national assets. They are tremendously scientifically productive, making many of the major discoveries that are reported in the media and that rewrite textbooks. Extending Science â€" NASA's Space Science Mission Extensions and the Senior Review Process evaluates the scientific benefits of missions extensions, the current process for extending missions, the current biennial requirement for senior reviews of mission extensions, the balance between starting new missions and extending operating missions, and potential innovative cost-reduction proposals for extended missions, and makes recommendations based on this review.
