DOWNLOAD EBOOKWho or what really killed the young son of Southern Baptist preacher Gareth Holbright? Where do the sympathies of straight-laced military commander John Herman really lie? What’s behind the cover-up of the closed moon colony? And will commitment-phobic Max and ambitious journalist Tina ever reunite? The first book in the Cassiopeia Chronicles, The Right Asteroid is set in the early years of the twenty-second century, when human colonies in space have created the equivalent of a new Wild West. Freedom-loving asteroid hunter Max Julian wants nothing more than to have some fun and make enough money to pay off her space ship, in that order. Instead, what she’d thought was her last-chance asteroid turns out to be an alien probe – and Max makes first contact, setting off a chain of events that will change human life on earth, the moon, and Mars forever. Along the way, Max joins forces with an unlikely new team of human friends to save the lives of a half-million geometry-loving, high-tech aliens who call themselves the Kurool. But EarthGov will stop at nothing to prevent the aliens from settling on Mars. Meet Max’s friends: Lodan Greenfellow, an inquisitive agronomist, wants to understand the mystery of the aliens on Mars, but EarthGov wants to destroy the aliens and anyone who gets in their way. She might be in their cross hairs. Gareth Holbright, a grieving Southern Baptist minister, wants to mourn the loss of his son, but finds himself embroiled in the political race for the new EarthGov president and on the opposite side from his anti-alien brother. Tina Fiorici, an intrepid journalist for the New York Times, wants to write the real story about what’s happening with the aliens on Mars and about the burgeoning movement for independence. But the EarthGov doesn’t want the truth to get out. John Herman, a straight-laced military commander, just wants to keep his career on track, but learning what EarthGov has planned for the aliens makes him willing to risk it all.

DOWNLOAD EBOOKAsteroids suggest images of a catastrophic impact with Earth, triggering infernos, tidal waves, famine, and death -- but these scenarios have obscured the larger story of how asteroids have been discovered and studied. During the past two centuries, the quest for knowledge about asteroids has involved eminent scientists and amateur astronomers, patient research and sudden intuition, advanced technology and the simplest of telescopes, newspaper headlines and Cold War secrets. Today, researchers have named and identified the mineral composition of these objects. They range in size from 33 feet to 580 miles wide and most are found in a belt between the orbits of Mars and Jupiter. Covering all aspects of asteroid investigation, Curtis Peebles shows how ideas about the orbiting boulders have evolved. He describes how such phenomena as the Moon's craters and dinosaur extinction were gradually, and by some scientists grudgingly, accepted as the results of asteroid impacts. He tells how a band of icy asteroids rimming the solar system, first proposed as a theory in the 1940s, was ignored for more than forty years until renewed interest and technological breakthroughs confirmed the existence of the Kuiper Belt. Peebles also chronicles the discovery of Shoemaker-Levy 9, a comet with twenty-two nuclei that crashed into Jupiter in 1994, releasing many times the energy of the world's nuclear arsenal. Showing how asteroid research is increasingly collaborative, the book provides insights into the evolution of scientific ideas and the ebb and flow of scientific debate.

DOWNLOAD EBOOKThis “accessible and always entertaining” (Booklist) combination of history, pop science, and in-depth reporting offers a fascinating account of the asteroids that hit Earth long ago and those streaming toward us now, as well as how prepared we are against asteroid-caused catastrophe. One of these days, warns Gordon Dillow, the Earth will be hit by a comet or asteroid of potentially catastrophic size. The only question is when. In the meantime, we need to get much better at finding objects hurtling our way, and if they’re large enough to penetrate the atmosphere without burning up, figure out what to do about them. We owe many of science’s most important discoveries to the famed Meteor Crater, a mile-wide dimple on the Colorado Plateau created by an asteroid hit 50,000 years ago. In his masterfully researched Fire in the Sky, Dillow unpacks what the Crater has to tell us. Prior to the early 1900s, the world believed that all craters—on the Earth and Moon—were formed by volcanic activity. Not so. The revelation that Meteor Crater and others like it were formed by impacts with space objects has led to a now accepted theory about what killed off the dinosaurs, and it has opened up a new field of asteroid observation that is brimming with urgency. Dillow looks at great asteroid hits of the past and modern-day asteroid hunters and defense planning experts, including America’s first Planetary Defense Officer. Satellite sensors confirm that a Hiroshima-scale blast occurs in the atmosphere every year, and a smaller, one-kiloton blast every month. While Dillow makes clear that the objects above can be deadly, he consistently inspires awe with his descriptions of their size, makeup, and origins. Both a riveting work of popular science and a warning to not take for granted the space objects hurtling overhead, Fire in the Sky is, ultimately, a testament to our universe’s celestial wonders.

DOWNLOAD EBOOK"Asteroids come in all shapes and sizes--and hit our planet in them, too. But what happens if a catastrophically large one approaches earth? By looking on the ground at historical asteroid craters and present-day falls, and up into space for the big ones yet to come, a wide variety of scientists are trying to figure out how to track asteroids--and how to avoid devastating impacts in the future."--
