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.
