Given the task definition and input, reply with output. In this task, five ordered key facts are given. All the given facts are expressed in natural language. Your job is to generate a story 100 to 1000 words long, that includes all the facts given as input in their order of appearance while expanding upon them to produce a broader, yet coherent, narrative.

Fact1: international consortium of scientists operating as Project Inner Space in Tanganyika tap into Earth 's geothermal energy by drilling very deep hole down to Earth 's core, Fact2: scientists are foiled by extremely dense layer of material, Fact3: lower layers of crust have been weakened by decades of underground nuclear tests, Fact4: massive crack threaten very existence of Earth, Fact5: atomic device is used in hope of stopping crack
An international consortium of scientists, operating as Project Inner Space in Tanganyika, Africa, is trying to tap into the Earths geothermal energy by drilling a very deep hole down to the Earths core. The scientists are foiled by an extremely dense layer of material. To penetrate the barrier and reach the magma below, they intend to detonate an atomic device at the bottom of the hole. The leader of the project, Dr. Stephen Sorenson Dana Andrews, who is secretly dying of cancer, believes that the atomic device will burn its way through the barrier, but the projects chief geologist, Dr. Ted Rampion Kieron Moore, is convinced that the lower layers of the crust have been weakened by decades of underground nuclear tests, and that the detonation could produce a massive crack that would threaten the very existence of Earth. The atomic device is used and Rampions fears prove justified, as the crust of the Earth develops an enormous crack that progresses rapidly. Sorenson discovers that there was a huge reservoir of hydrogen underground, which turned the small conventional atomic explosion into a huge thermonuclear one that was millions of times more powerful. Another atomic device is used in the hope of stopping the crack, but it only reverses the cracks direction. Eventually the crack returns to its starting point at the test site, and a huge chunk of the planet outlined by the crack is expected to be thrown out into space. Sorenson remains at the underground control center to record the event despite pleas by his wife Maggie to evacuate with the rest of the project staff. She and Rampion barely escape in time to observe the fiery birth of a second moon. Its release stops the crack from further splitting the Earth.
