Science Illustrated: Mega Rockets

by Enyo Richie

Yeah okay that’s pretty terrible Latin, but it’smeant to be a play on the oldair force motto “per ardua adastra”, or “through adversityto the stars”. In this case, it’sthrough a huge flame. Meh,the Romans didn’t haverockets, I did my best. Please send complaints to theemail below - but only in Latin.Anyway, the point here is that the age of thebig lifters may be dawning anew. Space-X testedits Falcon Heavy this year, a test that ended witha truly spectacular synchronised dual-boosterlanding, and that’s the little one in the newgeneration. Our feature starting on page 24 detailsthe lineup, but of particular interest is NASA’sSpace Launch System (below, left).Following the cancellation of the Constellationprogram and the Ares I and Ares V Mars-shotrockets, NASA had to come up with somethingcheaper. The SLS is derived from Space Shuttle techbut the important aspect is that it can be upgradedover time. The first mission might not break toomany records, but NASA hopes this rocket will stilleventually take someone to Mars.

Sky and Telescope : The Essential Book of Astronomy

by Richard Jones

TO BORROW SOME WORDS from the title of a famous book and movie,the adventure of amateur astronomy really is a ‘never-ending story’. Ourcosmic vistas are essentially unlimited, even by aperture — for no matterwhat the size of our observing instrument(s), we can never hope to do morethan just scratch the surface of all the planetary, galactic and intergalacticpossibilities out there in the Universe.Which I guess is why many of us tend to specialise in one field oranother, whether that be hunting faint fuzzies or scanning for comets. In2018, there’ll pretty much be something for everyone. If you’re into theMoon, we’ll have two total lunar eclipses. If you’re into planets, we’ll havethe opposition of Mars in July (the best one in years). If you’re into deepsky observing, you will, of course, have multitudes of targets to keep youoccupied year-round. And we’re so lucky here in the Southern Hemisphere,to have galactic targets galore — both the central region of our galaxy inSagittarius, and the two Magellanic Clouds with their deep sky delightssuch as the Tarantula nebula.If you traditionally focus on one particular field of observationalastronomy, perhaps 2018 can be the year when you give some of the otherareas a go. There’s always something new to see.

Solar Particle Radiation Storms Forecasting and Analysis: The HESPERIA HORIZON 2020 Project and Beyond (Astrophysics and Space Science Library Book 444)

by Olga E. Malandraki

Solar energetic particles (SEPs) emitted from the Sun are a major space weather hazard motivating the development of predictive capabilities. This book presents the results and findings of the HESPERIA (High Energy Solar Particle Events forecasting and Analysis) project of the EU HORIZON 2020 programme. It discusses the forecasting operational tools developed within the project, and presents progress to SEP research contributed by HESPERIA both from the observational as well as the SEP modelling perspective. Using multi-frequency observational data and simulations HESPERIA investigated the chain of processes from particle acceleration in the corona, particle transport in the magnetically complex corona and interplanetary space, to the detection near 1 AU. The book also elaborates on the unique software that has been constructed for inverting observations of relativistic SEPs to physical parameters that can be compared with space-borne measurements at lower energies. Introductory and pedagogical material included in the book make it accessible to students at graduate level and will be useful as background material for Space Physics and Space Weather courses with emphasis on Solar Energetic Particle Event Forecasting and Analysis.This book is published with open access under a CC BY license.

Leaving the Planet by Space Elevator

by Linda Phillips

It is an astonishing thing that, in this age of technological progress, a new idea can appear, seemingly out of nowhere. Yet the invention of the Space Elevator has had just such an impact. In the past decade it moved from science fiction to an engineering project. With a Foreword by the late Sir Arthur C. Clarke, you will be amazed by this project.

Rosetta's comet: Churyumov-Gerasimenko

by Codex Regius

The world was moved to pity when the little Philae spacecraft jumped on Rosetta’s comet into its undoing. But the European parent probe, Rosetta, continued to orbit the ‘rubber duck‘ comet with the ineffable name and made amazing discoveries. Is 67P/Churyumov-Gerasimenko really a messenger from that part of the solar system in which the dwarf planets are orbiting: a baby pluto, so to speak?The Rosetta mission has long since been concluded. Its findings are summarized in this book that also presents impressive images of comet 67P. ‘Rosetta has completely changed the understanding of comets.’

Interferometry and Synthesis in Radio Astronomy (Astronomy and Astrophysics Library)

by A. Richard Thompson

This book is open access under a CC BY-NC 4.0 license.The third edition of this indispensable book in radio interferometry provides extensive updates to the second edition, including results and technical advances from the past decade; discussion of arrays that now span the full range of the radio part of the electromagnetic spectrum observable from the ground, 10 MHz to 1 THz; an analysis of factors that affect array speed; and an expanded discussion of digital signal-processing techniques and of scintillation phenomena and the effects of atmospheric water vapor on image distortion, among many other topics.With its comprehensiveness and detailed exposition of all aspects of the theory and practice of radio interferometry and synthesis imaging, this book has established itself as a standard reference in the field. It begins with an overview of the basic principles of radio astronomy, a short history of the development of radio interferometry, and an elementary discussion of the operation of an interferometer. From this foundation, it delves into the underlying relationships of interferometry, sets forth the coordinate systems and parameters to describe synthesis imaging, and examines configurations of antennas for multielement synthesis arrays. Various aspects of the design and response of receiving systems are discussed, as well as the special requirements of very-long-baseline interferometry (VLBI), image reconstruction, and recent developments in image enhancement techniques and astrometric observations. Also discussed are propagation effects in the media between the source and the observer, and radio interference, factors that limit performance. Related techniques are introduced, including intensity interferometry, optical interferometry, lunar occultations, tracking of satellites in Earth orbit, interferometry for remote Earth sensing, and holographic measurements of antenna surfaces. This book will benefit anyone who is interested in radio interferometry techniques for astronomy, astrometry, geodesy, or electrical engineering.

Cicada Spring: A Novel

by Christian Galacar

On a warm May evening in the spring of 1979, the people of Heartsridge, Massachusetts, are living the American dream. Families are gathered for barbecues. Kids are playing in front yards. Gardens are being kept. Meanwhile, Kara Price stumbles home through the woods, raped and beaten, her life shattered by a wicked act of violence, perpetrated by one of the town’s most beloved and public figures.

Surrounding Kara is a cast of compelling and nefarious characters—a violent-tempered mayor who can do no wrong in the eyes of the town, a sheriff bound by the rules and plagued by a guilty conscience, a father bent on revenge, a serial killer in the midst of an identity crisis. And at the center of it all there's Kara, who just wants to move on with her life and forget everything that happened to her. But how can she do that when everyone thinks she is a liar who is only out for attention? With plot and emotion braided together by a careful hand, this haunted group of people all acting on behalf of their own interests begs the question: How far would you go to protect your own?
