Second Moon

When the third interstellar visitor, comet 3I/ATLAS, passed through the solar system, the world felt for the first time that the universe was not a silent background, but an ocean that could break into unknown visitors at any time. Scientists predict that in the next ten to twenty years, humans will capture interstellar objects more and more frequently. This means that we must prepare for an unpredictable future in advance. In the shadow of energy crisis, climate catastrophe and political disputes, an unprecedented idea was proposed: all mankind to jointly build an artificial celestial body - a "second moon." It is not only a backup home for civilization, but also an experimental ground for energy and ecology. From the initial sneers and doubts, to the establishment of the Earth Council, to the operation of the Lagrange point factory and the success of micro-spheres, mankind has gradually brought fantasy closer to reality. The game between science and politics, the collision between capital and ideals, and the battle between education and fairness are all unfolding on this unformed moon. When the skeleton of the second moon appears in the night sky of the Earth for the first time, and when the artificial moonlight it emits illuminates human cities, human civilization will usher in a real turning point. It is not only a backup planet, but also a mothership sailing to the stars. "Second Moon" is a hard science fiction epic about planning for a rainy day. It uses real science as the cornerstone and a global perspective as the stage to depict how humans find paths to survival, cooperation and transcendence in the intertwining of energy, politics and the universe.
