He starts a personal mission to extract ice from a comet, Greg’s Skeleton.
A billionaire named Sean Probst, Dinah’s boss, realizes the Cloud Ark will need a source of water for its inhabitants to drink and to continue propelling the space station and preventing it from falling out of orbit. There are hints, however, that the entire project is not really feasible that it’s only intended to pacify people and give false hope. The Ark must become self-sufficient enough to endure for 5,000 years-at which point Earth should be stable enough to be terraformed and turned into a habitable planet once more. Engineer Dinah MacQuarie uses robots to excavate Amalthea to provide further protection for the station. The space station is already bolted onto an asteroid called Amalthea and is partially protected from the Moon fragments. The Cloud Ark is constructed around the International Space Station, currently headed by astronaut Ivy Xiao. The Ark will take the form of “arklet” vessels small enough to avoid the debris from the Moon. Every country draws lots for a small group of its young people to join the Ark. This Ark may be a means of preserving the human race and preventing worldwide chaos. As a result of Harris’s calculations, a decision is made to build a “Cloud Ark” that will evacuate 1,500 of the Earth’s people. The Earth’s atmosphere will become so hot, the oceans will boil away and the planet will become inhospitable to life. Within two years, those fragments will form what he calls a “Hard Rain” of meteors that will burn up in the atmosphere. Soon, smaller fragments of the Moon will enter the Earth’s atmosphere. The fragments collide with each other, and astronomer “Doc” Dubois Harris explains that the collisions will increase.
