Launch of Pioneer 6 on a Delta-E rocket Pioneer 8 being prepared for launch Launch of Pioneer 8 on a Delta-E1 rocket. Each craft was identical. They were spin-stabilized 0.94 m (3 ft 1 in) diameter × 0.81 m (2 ft 8 in) tall cylinders with a 1.8 m (5 ft 11 in) long magnetometer boom and solar panels mounted around the body.
It was an emergency that came at the worst possible time. The Robledo, Spain antenna discontinued its tracking of Pioneer 8 and began to search for the lost spacecraft. When Mars came into view for Goldstone, the Pioneer 26m antenna joined the search, while the Echo 26m antenna continued tracking Mariner 6.
Pioneer 9 (Pioneer D) – launched November 1968 (inactive since 1983) Pioneer E – lost in launcher failure August 1969; Pioneer 6 and Pioneer 9 are in solar orbits with 0.8 AU distance to the Sun. Their orbital periods are therefore slightly shorter than Earth's. Pioneer 7 and Pioneer 8 are in solar orbits with 1.1 AU distance to the Sun.
Pioneer 10 was assembled around a hexagonal bus with a 2.74-meter (9 ft 0 in) diameter parabolic dish high-gain antenna, and the spacecraft was spin stabilized around the axis of the antenna. Its electric power was supplied by four radioisotope thermoelectric generators that provided a combined 155 watts at launch.
The Pioneer plaques are a pair of gold-anodized aluminum plaques that were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft, featuring a pictorial message, in case either Pioneer 10 or 11 is intercepted by intelligent extraterrestrial life. The plaques show the nude figures of a human male and female along with several symbols ...

Pioneer 11 (also known as Pioneer G) is a NASA robotic space probe launched on April 5, 1973, to study the asteroid belt, the environment around Jupiter and Saturn, the solar wind, and cosmic rays. [2] It was the first probe to encounter Saturn, the second to fly through the asteroid belt, and the second to fly by Jupiter.
