The first spacecraft to explore Jupiter was Pioneer 10, which flew past the planet in December 1973, followed by Pioneer 11 twelve months later. Pioneer 10 obtained the first close-up images of Jupiter and its Galilean moons; the spacecraft studied the planet's atmosphere, detected its magnetic field, observed its radiation belts and determined ...
Juno in launch configuration. Juno is a NASA space probe orbiting the planet Jupiter.It was built by Lockheed Martin and is operated by NASA 's Jet Propulsion Laboratory.The spacecraft was launched from Cape Canaveral Air Force Station on August 5, 2011 UTC, as part of the New Frontiers program.

It was delivered into Earth orbit on October 18, 1989, by Space Shuttle Atlantis on the STS-34 mission, and arrived at Jupiter on December 7, 1995, after gravity assist flybys of Venus and Earth, and became the first spacecraft to orbit Jupiter. The spacecraft then launched the first probe to directly measure its atmosphere.
The perijove of orbit (point of closest approach to Jupiter) was increased to keep the spacecraft out of the most intense radiation regions. A radio-science experiment analyzed Ganymede's gravitational field and internal structure. The instruments detected evidence of a self-generated magnetosphere around the moon.

A color view of Earth assembled from 82 images as the spacecraft spun, at an altitude of 1,987 miles (3,197 kilometers), 10 minutes before closest approach JunoCam views Earth (centered on South America) in October 2013 during the spacecraft's flyby en route to Jupiter
The best nights of all of 2022 to see Jupiter in the night sky are about to take place as the planet takes center stage in the night sky, a showing unlike any other in nearly six decades. The sun ...
NASA's Juno spacecraft recently flew by Jupiter, collecting crucial data -- and the best look we've gotten at the planet in a very long time. This is the closest photo of Jupiter anyone has seen ...
At the closest approach, the velocity of the spacecraft reached 132,000 km/h (82,000 mph; 37,000 m/s), [49] and it came within 132,252 kilometers (82,178 mi) of the outer atmosphere of Jupiter. Close-up images of the Great Red Spot and the terminator were obtained. Communication with the spacecraft then ceased as it passed behind the planet. [44]
