In ancient Egypt, Asia, and the Inca civilization, death masks were used to facilitate the spirit's journey in the afterlife.

Explorer I was the first American satellite. It was launched four months after the first artificial satellite, Sputnik I, was put into orbit by the Soviet Union, beginning the so-called space race.

It stopped transmission of data later in 1958, when its batteries died, but remained in orbit for more than 12 years. Where did it make its fiery reentry?
