Juno. The Juno spacecraft, which entered orbit around Jupiter on July 4, 2016, is the first explorer to peer below the planet's dense clouds to answer questions about the gas giant itself and the origins of our solar system. Now in an extended mission phase, the agency’s most distant planetary orbiter continues its investigation. Visit ...

4 天之前 · During its extended mission, Juno’s trajectory passes by Io every other orbit, flying over the same part of the moon each time. Previously, the spacecraft made close flybys of Io in December 2023 and February 2024, getting within about 930 miles (1,500 kilometers) of its surface.The latest flyby took place on Dec. 27, 2024, bringing the spacecraft within about …

2024年11月6日 · Juno completed its primary mission by mid-2021, offering revelations about Jupiter’s interior structure, atmosphere (including polar cyclones, deep atmosphere, and auroras), and magnetosphere – the vast region around the planet influenced by …

Juno 's mission is to measure Jupiter's composition, gravitational field, magnetic field, and polar magnetosphere. It will also search for clues about how the planet formed, including whether it has a rocky core, the amount of water present within the deep atmosphere, mass distribution, and its deep winds, which can reach speeds up to 620 km/h ...

NASA's Mission Juno is exploring Jupiter, seeking to unlock secrets of the giant planet and our solar system.

2024年12月30日 · Juno, U.S. space probe designed to orbit the planet Jupiter. The probe is named for a Roman goddess, the female counterpart to the god Jupiter. Juno was launched by an Atlas V rocket from Cape Canaveral, Florida, on August 5, 2011.

The extended mission will answer fundamental questions that arose during Juno’s prime mission. Juno was proposed in 2003 by a team led by SwRI’s Dr. Scott Bolton and launched in 2011. As the prime mission was wrapping up, the spacecraft and its instruments remained healthy, allowing for a mission extension beginning in August 2021.

2023年5月15日 · NASA’s Juno spacecraft will fly past Jupiter’s volcanic moon Io on Tuesday, May 16, and then the gas giant itself soon after. The flyby of the Jovian moon will be the closest to date, at an altitude of about 22,060 miles (35,500 kilometers).

2021年1月13日 · NASA has authorized a mission extension for its Juno spacecraft exploring Jupiter. The agency’s most distant planetary orbiter will now continue its investigation of the solar system’s largest planet through September 2025, or until the spacecraft’s end of life.

2018年7月9日 · Juno, with its suite of nine science instruments, was the first spacecraft to orbit the giant planet since the Galileo mission in the 1990s. It would be the first mission to make repeated excursions close to the cloud tops, deep inside the planet’s powerful radiation belts.
