"In one generation we have gone from extraterrestrial planets being a mainstay of science fiction, to the present, where Kepler has helped turn science fiction into today's reality," NASA Administrator Charles Bolden said in the announcement. "These discoveries underscore the importance of NASA's science missions, which consistently increase understanding of our place in the cosmos."
