"Humanity has finally made it to the stars. Colony worlds thrive and there is general peace among the settled systems. Until now. Matte black ships of an advanced design appear in colonial systems. Their drives and weapons are not extremely advanced beyond their Terran counterparts - just superior enough to be utterly devastating. Colonies and their populations are obliterated. Once settled worlds are rendered radioactive wastelands. Earth herself lies defenseless before the marauding enemy. DEFEND THE SKIES OF EARTH Standing against the invasion are two of humanity's finest starship captains, Winslow Price of the British Space Navy and Anika Ahuja of the Indian Space Forces. Compatriots. Fierce competitors. Former lovers. Now they are on a quest that will plumb the scientific wells of existence itself, where the primordial knot of spacetime may be unraveling. Price and Ahuja are sworn to do whatever it takes to defend Earth and humanity from ultimate obliteration by an enemy that will not even speak its name. Even if it pushes each to the brink of life and death in battle. Even if it leads each beyond space and time-and to the edge of ultimate possibility! TAKE THE BATTLE TO THE STARS"-- Provided by publisher

A brief guide to the real science of interstellar travel With known exoplanets now numbering in the thousands and initiatives like 100 Year Starship and Breakthrough Starshot advancing the idea of interstellar travel, the age-old dream of venturing forth into the cosmos and perhaps even colonizing distant worlds may one day become a reality. A Traveler’s Guide to the Stars reveals how. Les Johnson takes you on a thrilling tour of the physics and technologies that may enable us to reach the stars. He discusses the latest exoplanet discoveries, promising interstellar missions on the not-so-distant horizon, and exciting new developments in space propulsion, power, robotics, communications, and more. But interstellar travel will not be easy, and it is not for the faint of heart. Johnson describes the harsh and forbidding expanse of space that awaits us, and he addresses the daunting challenges—both human and technological—that we will need to overcome in order to realize tomorrow’s possibilities. A Traveler’s Guide to the Stars is your passport to the next great frontier of human discovery, providing a rare inside look at the remarkable breakthroughs in science and technology that will help tomorrow’s space travelers chart a course for the stars.

"The year is 2065 and an accidental encounter in space leads to the discovery that we are not alone and that our continued existence may be in jeopardy. Chris Holt, working at the Space Resources Corp., discovers that one of the asteroids he surveying for mining is actually a derelict spaceship. What Earth doesn't know is that across the galaxy, a war has been underway for millennia. A war between alien civilizations that have very different ideas about what should be done about emerging spacefaring civilizations like our own. The artificial intelligence resident in the derelict has been in our solar system since before the dawn of human civilization, watching, waiting and keeping quiet lest the war return and wipe out humanity"--

Exploring the profound impact of loss, the narrative delves into Les Johnson's personal journey after the death of his wife and the near loss of his daughter, Heather. The emotional turmoil and devastation that follow are depicted with vulnerability, making the experiences of grief and healing relatable to readers. Through this poignant retelling, the author captures the ripple effects of tragedy on family dynamics and the struggle to cope with such profound pain.

Part III of the book looks at how we can protect our satellites, preparing for the worst, reducing the growth and amount of orbital debris, preventing acts of war in space and hardening against space radiation.

Co trzeba zrobić, aby przenieść człowieka do innego układu gwiezdnego? Jakie wyzwania i dylematy stoją przed tymi, którzy chcą eksplorować kosmos? Jak dotychczasowe osiągnięcia naukowe przybliżają nas do realizacji tej misji? Na te pytania odpowiada Les Johnson, jeden z czołowych naukowców na świecie, aktywnie pracujący nad realizacją międzygwiezdnych lotów kosmicznych. Autor zabiera nas w ekscytującą podróż po fizyce i najnowszych technologiach, które mogą umożliwić wyprawę w kosmos i dotarcie do gwiazd. Pokazuje niezliczone wyzwania fizyczne, techniczne, biologiczne, społeczne, a nawet etyczne, które musimy pokonać, aby odwiedzić sąsiednie gwiazdy, i oferuje wnikliwy wgląd w to, jak te problemy mogą być rozwiązane. Przewodnik podróżnika po gwiazdach to przepustka do przekroczenia kolejnej wielkiej granicy ludzkich odkryć, oferująca wyjątkowe spojrzenie od środka na niezwykłe przełomy w nauce i technologii, które pomogą przyszłym podróżnikom kosmicznym wytyczyć kurs do gwiazd.
