Selene, also known as Kaguya, was a Japanese lunar orbiter launched in 2007 to study the Moon. It orbited at varying altitudes, gathering detailed images and data on lunar surface features, gravity, and magnetic fields. The mission aimed to improve understanding of the Moon’s composition, internal structure, and history, providing valuable insights for future exploration. Selene's instruments helped map the lunar surface with high precision, and its findings contributed to scientific knowledge about Earth's closest celestial neighbor. The mission concluded in 2009, leaving a wealth of data for scientists worldwide.
