Eugene “Gene” Shoemaker, a famous astronomer and geologist, was something of a legend in his field. He invented the scientific research of cosmic impacts and came up with the methods and techniques that Apollo astronauts used to research the Moon.
Shoemaker wanted to be an astronaut himself, but was turned down because of a minor medical issue. Throughout his life, this remained his biggest disappointment.
Still, hoping against hope, Shoemaker kept on dreaming that he would some day visit the Moon. When he died, NASA fulfilled his most precious wish and sent his ashes to the Moon with the Lunar Prospector in 1998. His ashes remain there, scattered among moon dust.
