With active geysers coating its surface with dazzlingly bright ice crystals, Saturn’s large moon Enceladus is one of the most enigmatic worlds in our solar system. Underlying this activity are numerous further discoveries by the Cassini spacecraft, tantalizing us with evidence that Enceladus harbors a subsurface ocean of liquid water. Enceladus is thus newly realized as a forefront candidate among potentially habitable ocean worlds in our own solar system, although it is only one of a family of icy moons orbiting the giant ringed planet, each with its own story. As a new volume in the Space Science Series, Enceladus and the Icy Moons of Saturn brings together nearly eighty of the world’s top experts writing more than twenty chapters to set the foundation for what we currently understand, while building the framework for the highest-priority questions to be addressed through ongoing spacecraft exploration. Topics include the physics and processes driving the geologic and geophysical phenomena of icy worlds, including, but not limited to, ring-moon interactions, interior melting due to tidal heating, ejection and reaccretion of vapor and particulates, ice tectonics, and cryovolcanism. By contextualizing each topic within the profusion of puzzles beckoning from among Saturn’s many dozen moons, Enceladus and the Icy Moons of Saturn synthesizes planetary processes on a broad scale to inform and propel both seasoned researchers and students toward achieving new advances in the coming decade and beyond.
Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.
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...
Loss and the infinite ways we attempt to come to terms with it permeate this absorbing psychological mystery set in the Finnish town of Turku. A week after his wife dies, Det. Kimmo Joentaa feels compelled to return to work to investigate the murder of a young woman smothered in her own bed while her husband was away. Only a valueless painting appears to have been stolen. A second murder, just as puzzling, occurs in a youth hostel where a young man is killed while others slept all around him.
As we speak, stunning new snapshots of our Solar System are being transmitted to Earth by a fleet of space probes, landers, and rovers. Yet nowadays, it is all too easy to take such images for granted amidst the deluge of competing visuals we scroll through every day. To truly understand the value of these incredible space photos, we first need to understand the tools that made them possible. This is the story of imaging instruments in space, detailing all the technological missteps and marvels that have allowed us to view planetary bodies like never before. From the rudimentary cameras launched in the 1950’s to the cutting-edge imaging instruments onboard the Mars Perseverance rover, this book covers more than 100 imaging systems sent aboard various spacecraft to explore near and distant planetary bodies. Featured within are some of the most striking images ever received by these pioneering instruments, including Voyager’s Pale Blue Dot, Apollo’s Blue Marble, Venera’s images from the surface of Venus, Huygens’ images of Titan, New Horizon’s images of Pluto and Arrokoth, and much more. Along the way, you will learn about advancements in data transmission, digitization, citizen science, and other fields that revolutionized space imaging, helping us peer farther and more clearly across the Solar System.

The Saturn System Through The Eyes Of Cassini is printed in full-color on 70-pound paper. The Cassini-Huygens mission has revolutionized our knowledge of the Saturn system and revealed surprising places in the solar system where life could potentially gain a foothold--bodies we call ocean worlds. Since its arrival in 2004, Cassini-Huygens has been nothing short of a discovery machine, captivating us with data and images never before obtained with such detail and clarity. Cassini taught us that Saturn is a far cry from a tranquil lone planet with delicate rings. Now, we know more about Saturn's chaotic, active, and powerful rings, and the storms that rage beneath. Images and data from Saturn's moons Titan and Enceladus hint at the possibility of life never before suspected. The rings of Saturn, its moons, and the planet itself offer irresistible and inexhaustible subjects for intense study. As the Cassini mission comes to a dramatic end with a fateful plunge into Saturn on Sept. 15, 2017, scientists are already dreaming of going back for further study.
Who killed Keesha Leder? Was it a water burglary gone wrong? Was it a dehydrated squatter trying to stave off a thirsty death? Was it the religious sect known as Sectarians trying to replenish their inventory of drinkable water? Or was it her husband, Moss, who was falling in love with his assistant, Zoe? There are plenty of other motivated suspects (and murders) in this Multi Century Whodunnit! Thirsty Planet takes place in two time periods and is packed with political corruption, greed, murder, and even an inter-century love affair. It's the year 2121 and the veneer of civilization is crumbling. When the wife of physicist, Moss Leder, is brutally murdered during the apparent theft of the couple's drinking water, Leder vows to journey to the previous century where he hopes to alter the flow of events that led to his world's personal and ecological tragedies. Leder has been secretly dabbling with time travel and is close to achieving success. His plan is violently opposed by the political power brokers of the day, and by his employer, Rafe Bradshaw, whose private black market water business is threatened by the scheme. This leads to open warfare between those who control the water resources and those who don't, with Leder emerging as the charismatic leader of the latter. A century earlier, in 2022, Cassie Lopez, is an environmental specialist in the Administration of President Samantha Blackwell. She has uncovered evidence linking the powerful Senator Alphonse Grimsby to the murder of several environmental activists. When Cassie tries to make this information public, powerful forces are unleashed that threaten to destroy her and her husband, Paul. When our 22nd century physicist and our 21st century politician team up to try to fix things, all hell breaks loose. The paradox of time travel brings both stories and love affairs together with a satisfying resolution in the year 2104. Using current climate science and theories about the nature of time, this is a fast moving mystery novel. And for people who like literary puzzles, there is an allegory with clues to be found in the key character's names.
It is a great science fiction story, based on studies made by NASA in its tireless search to find other places in the universe to which man would seek the way to inhabit them.The great secret that the United States had kept was the study that had been done to the moons on Jupiter and Saturn. It is possible that in all the last years the human being wants to survive his own capacity for destruction and look for the technology of traveling between planets . If we were so lucky, humanity had an extension of several years during which you can seek asylum.Many years have been devoted to calculating how global warming and overpopulation will affect and what their implications for life will be. The habitable zone of the Solar System (that in which temperatures allow liquid water) would be between Jupiter and Saturn.And that's where a manned mission will depart to the designated destination and our characters will live many adventures and challenges in the vastness of space.
