first probe to cross the asteroid belt; first Jupiter probe; first man-made object on an interstellar trajectory; now in the outer regions of the Solar System but no longer contactable 1972-012A: Pioneer 11: NASA: 4 December 1974 flyby success went on to visit Saturn 1973-019A: Voyager 1: NASA: 5 March 1979 flyby success went on to visit Saturn ...
Mission: investigating Jupiter and Saturn, and the moons of these planets. Its continuing data feed offered the first direct measurements of the heliosheath and the heliopause. It is currently the furthest man-made object from Earth, as well as the first object to leave the heliosphere and cross into interstellar space.

The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Observation of the spacecraft communications as it passed behind Jupiter would allow measurements of the planetary atmosphere, while tracking data would improve estimates of the mass of Jupiter and its moons. [6] NASA Ames Research Center, rather than Goddard, was selected to manage the project as part of the Pioneer program. [10]
The camera system was designed to obtain images of Jupiter's satellites at resolutions 20 to 1,000 times better than Voyager 's best, because Galileo flew closer to the planet and its inner moons, and because the more modern CCD sensor in Galileo 's camera was more sensitive and had a broader color detection band than the vidicons of Voyager.

Sinope / s ə ˈ n oʊ p iː / is a retrograde irregular satellite of Jupiter discovered by Seth Barnes Nicholson at Lick Observatory in 1914, [1] and is named after Sinope of Greek mythology. Sinope did not receive its present name until 1975; [10] [11] before then, it was simply known as Jupiter IX. It was sometimes called "Hades" [12 ...
