パイオニア計画
Pioneer 0 (also known as Able 1) was a failed United States space probe that was designed to go into orbit around the Moon, carrying a television camera, a micrometeorite detector and a magnetometer, as part of the first International Geophysical Year (IGY) science payload. It was designed and operated by the Air Force Ballistic Missile Division as the first spacecraft in the Pioneer program and was the first attempted launch beyond Earth orbit by any country, but the rocket failed shortly after launch. The probe was intended to be called Pioneer (or Pioneer 1), but the launch failure precluded that name.
