Purpose. Pioneers 6, 7, 8, and 9 were created to make the first detailed, comprehensive measurements of the solar wind, solar magnetic field and cosmic rays. They were designed to measure large scale magnetic phenomena and particles and fields in interplanetary space. Data from the vehicles have been used to better understand stellar processes ...

The Pioneer programs were two series of United States lunar and planetary space probes exploration. The first program, which ran from 1958 to 1960, unsuccessfully attempted to send spacecraft to orbit the Moon, successfully sent one spacecraft to fly by the Moon, and successfully sent one spacecraft to investigate interplanetary space between the orbits of Earth and Venus.
Pioneer 11 →. Pioneer 10 (originally designated Pioneer F) is a NASA space probe launched in 1972 that completed the first mission to the planet Jupiter. [ 6] Pioneer 10 became the first of five planetary probes and 11 artificial objects to achieve the escape velocity needed to leave the Solar System.
The history of Vietnam can be traced back to around 20,000 years ago. The first modern humans to arrive and settle in the area of modern-day Vietnam are known as the Hoabinhians, who can be traced as the ancestors of modern-day Negritos. Archaeological findings from 1965, which are still under research, show the remains of two hominins closely ...
The first were Pioneer 10 in 1973, and Pioneer 11 a year later, taking low-resolution images of the four Galilean moons and returning data on their atmospheres and radiation belts. [75] The Voyager 1 and Voyager 2 probes visited Jupiter in 1979, discovering the volcanic activity on Io and the presence of water ice on the surface of Europa .
Pioneer 11 made a similar flyby in 1974. [28] Data sent back by the two spacecraft was used to determine the moon's physical characteristics [110] and provided images of the surface with up to 400 km (250 mi) resolution. [111] Pioneer 10's closest approach was 446,250 km, about 85 times Ganymede's diameter. [112]
