Charlie: the 50,000-year-old astronaut on the Moon
Explorers find a spacesuited human corpse, nicknamed Charlie, in a lunar cave and date it to 50,000 years old, long before any human civilization. Physicist Victor Hunt coordinates biologists, linguists and engineers under UNSA. Charlie's decoded diary and a 25-million-year-old alien ship found on Ganymede lead to the answer: Charlie's people, the Lunarians, lived on a lost planet, Minerva, whose destruction left the asteroid belt. Minerva's moon was captured by Earth, and Lunarian survivors who landed on Earth became the ancestors of modern humans.
