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.
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.
Crewed launch vehicles, with the exception of the Space Shuttle, [34] have employed a launch escape system to save the lives of the crew in case their carrier rocket malfunctions. [35] A flight termination system typically consists of two sets of the following components: [26] An antenna system, which receives commands from the range,
A special characteristic was a UHF transmit antenna reflector 4.9 m in diameter. Each satellite had 12 transponders, which worked in the UHF range from 240 - 400 megahertz. Additionally FLTSATCOM 7 and 8 included an experimental EHF transponder built by Lincoln Laboratory intended to test the MILSTAR ground terminals. The first seven satellites ...
The AAI RQ-2 Pioneer is an unmanned aerial vehicle (UAV) that was used by the United States Navy, Marine Corps, and Army, and deployed at sea and on land from 1986 until 2007. Initially tested aboard USS Iowa , the RQ-2 Pioneer was placed aboard Iowa -class battleships to provide gunnery spotting, its mission evolving into reconnaissance and ...
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 5 with test equipment. The recorded digital data were transmitted at 1, 8, and 64 bit/s, depending on the distance of the spacecraft from Earth and the size of the receiving antenna. Weight limitations on the solar cells prevented continuous operation of the telemetry transmitters. About four operations of 25 min duration were scheduled ...
Fox-1B, AO-91 or AMSAT OSCAR 91 [3] is a United States amateur radio satellite.It is a 1U Cubesat, was built by the AMSAT-NA and carries a single-channel transponder for FM radio.
