A 2075 solar system calamity is approaching. Earth's projected collision with Apex comet in 3055 requires relocation of some segment of earth's population if humanity is to survive.
The moon will also be destroyed in the collision. Mars is the closest site to relocate new generations, but at 140 million miles, it's too far.
The United States-China federation, led by president Thomas Jason, makes the secret decision to construct a "PlaNet" a quarter the size of the moon to house humanity some two million miles from earth. The plan is contrary to Mars colonists' plans and is fueled by Jason's enormous greed and the United World Mine Workers' bribery scheme geared to lock up lucrative decades-long contracts to extract the raw material necessary to build PlaNet.
If left unchecked, Jason's untenable plan guarantees humanity's extinction well ahead of earth's impending destruction.
