Chinese Lunar Exploration Program
Chang'e (, unofficially rendered as Chang-Er or Chang-o for simpler pronunciation), originally known as Heng'e, is the Chinese goddess of the Moon. She is the subject of several legends in Chinese mythology, most of which incorporate several of the following elements: Houyi the archer, a benevolent or malevolent emperor, an elixir of life, and the Moon. She was married to Houyi. In modern times, Chang'e has been the namesake of the Chinese Lunar Exploration Program.
