The Cassini Code


Book Description

When the tail of the comet Bhaktul flicks through the Earth's atmosphere, deadly particles are left in its wake, and mankind is confronted with a virus that devastates the adult population. A renowned scientist proposes a bold plan: to build a ship that will carry a crew of 251 teenagers to a home in a distant solar system. Two years later, Galahad and its crew is launched. If their mission fails, it will be the end of the human race... The teenage crew of Galahad has survived their first encounter with an alien race. Though shaken by the power of The Cassini, Triana and her Council are determined to continue their mission. But some of the crew don't agree. Led by the charismatic Merit Simms, a small group of crew members begins lobbying for a return to Earth—just as the ship enters the Kuiper Belt, the deadly minefield of asteroids that surrounds the solar system. As Galahad dodges a storm of asteroids, Triana finds herself dealing with an increasingly hostile crew. Even some members of the Council are beginning to listen to Merit's arguments. Can Triana find a way to prevent a mutiny aboard Galahad, and lead her crew to safety?

The Cassini-Huygens Mission


Book Description

The joint NASA-ESA Cassini-Huygens mission promises to return four (and possibly more) years of unparalleled scientific data from the solar system’s most exotic planet, the ringed, gas giant, Saturn. Larger than Galileo with a much greater communication bandwidth, Cassini can accomplish in a single flyby what Galileo returned in a series of passes. Cassini explores the Saturn environment in three dimensions, using gravity assists to climb out of the equatorial plane to look down on the rings from above, to image the aurora and to study polar magnetospheric processes such as field-aligned currents. Since the radiation belt particle fluxes are much more benign than those at Jupiter, Cassini can more safely explore the inner regions of the magnetosphere. The spacecraft approaches the planet closer than Galileo could, and explores the inner moons and the rings much more thoroughly than was possible at Jupiter. This book is the second volume, in a three volume set, that describes the Cassini/Huygens mission. This volume describes the in situ investigations on the Cassini orbiter: plasma spectrometer, ion and neutral mass spectrometer, energetic charged and neutral particle spectrometer, magnetometer, radio and plasma wave spectrometer and the cosmic dust analyzer. This book is of interest to all potential users of the Cassini-Huygens data, to those who wish to learn about the planned scientific return from the Cassini-Huygens mission and those curious about the processes occurring on this most fascinating planet. A third volume describes the remote sensing investigations on the orbiter.




The Ringed Planet, Second Edition


Book Description

On September 15, 2017, the Cassini spacecraft sent its final transmission to the Earth as it entered the atmosphere of Saturn, ending its historic 13 year mission at the ringed planet. This book is a beautifully illustrated journey of discovery through the Saturn system. Cassini's instruments have revealed never seen before details, including the only extraterrestrial lakes known in the solar system, and have provided unprecedented views of the rings, moons, and the planet itself. Results from Cassini's dramatic Grand Finale of ring-grazing and planet-skimming orbits are included in this expanded and updated second edition. Saturn is the jewel of the solar system. The Cassini spacecraft has been exploring the ringed planet and its moons and rings since 2004 and has helped us solve many of its mysteries while generating a wealth of new questions. Cassini has observed the bizarre mountains of Iapetus, the geysers of Enceladus, the lakes of Titan, and the dynamic and evolving rings. Along the way, this book explores and explains the fundamental processes that shape not just the Saturn system, but planets and moons in general. Written for the general audience with an emphasis on the fundamental physics of planetary systems, The Ringed Planet is a fascinating exploration of the Saturn system that places Saturn in the context of the solar system as a whole. Cassini's instruments have revealed Enceladus and Titan to have subsurface oceans of liquid water. Its cameras have returned stunning images of rings in turmoil, a tumbling moon, the only extraterrestrial lakes known in the solar system, a hexagon of clouds, some of the highest mountains in the solar system and much more. More than a journey of discovery at Saturn, The Ringed Planet is also an introduction to how planetary systems work.




A Curious Moon


Book Description

Starting an application is simple enough, whether you use migrations, a model-synchronizer or good old-fashioned hand-rolled SQL. A year from now, however, when your app has grown and you're trying to measure what's happened... the story can quickly change when data is overwhelming you and you need to make sense of what's been accumulating. Learning how PostgreSQL works is just one aspect of working with data. PostgreSQL is there to enable, enhance and extend what you do as a developer/DBA. And just like any tool in your toolbox, it can help you create crap, slice off some fingers, or help you be the superstar that you are.That's the perspective of A Curious Moon - data is the truth, data is your friend, data is your business. The tools you use (namely PostgreSQL) are simply there to safeguard your treasure and help you understand what it's telling you.But what does it mean to be "data-minded"? How do you even get started? These are good questions and ones I struggled with when outlining this book. I quickly realized that the only way you could truly understand the power and necessity of solid databsae design was to live the life of a new DBA... thrown into the fire like we all were at some point...Meet Dee Yan, our fictional intern at Red:4 Aerospace. She's just been handed the keys to a massive set of data, straight from Saturn, and she has to load it up, evaluate it and then analyze it for a critical project. She knows that PostgreSQL exists... but that's about it.Much more than a tutorial, this book has a narrative element to it a bit like The Martian, where you get to know Dee and the problems she faces as a new developer/DBA... and how she solves them.The truth is in the data...
