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.
It's the beginning of a new golden age of space exploration. Finally, humanity is taking the commercialization of space to the next level-mining asteroids. The new gold rush of the commercial space era has begun.
Another commercial venture, an attempt to put a hotel on the Moon, is seeking the space tourism gold of the ultra wealthy. And it seems as if the dream of finally sending people to Mars is finally going to happen using a ship propelled by a powerful nuclear rocket.
But space travel isn't cut and dry, and there is nothing routine about it. In order to mine an asteroid the goal is to bring it closer to Earth, but orbital mechanics are tricky and close to Earth proves to be far too close for comfort-with looming destruction from space about to become a grim reality. Now astronauts, scientists, engineers, and people in all the burgeoning space businesses must team together to stop the asteroid before it is too late for humanity and the planet it calls home.
THE SECOND TIME AROUND-IS HARDER . . .
Decades after the last footprints were left on the Moon, the US was preparing to return to the Lunar surface in a new class of rockets, when the mission suddenly became much more urgent. It would have to be a rescue mission.
Unbeknownst to the rest of the world China had sent its own Lunar expedition. A manned expedition. Until a distress call was received, no human outside of China even knew that the mission was manned-or that their ship had crash-landed and couldn't take off again.
Time was running out, and if the four Chinese astronauts were to be rescued, the American lunar mission would have to launch immediately, with only a skeleton crew. Once the heroic US astronauts were underway the army of engineers and scientists back home had the daunting task of deciding what equipment could be left on the Moon to permit the Lunar lander vehicle vehicle to lift safely from the Moon with the two US astronauts and the four stranded Chinese taikonauts! Could the US mount such a mission successfully-and would thousands of years of instilled honor 'allow' the Chinese astronauts to accept a rescue?
