Topic: NASA’s Juno Spacecraft
This expansion tasks Juno with becoming an explorer of the full Jovian system – Jupiter and its rings and moons – with multiple rendezvous planned for three of Jupiter’s most intriguing Galilean moons: Ganymede, Europa, and Io. ![]() This view of Jupiter’s atmosphere from NASA’s Juno spacecraft includes something remarkable, two storms caught in the act of merging.

NASA extends Juno, Insight missions
The missions – Juno and InSight – have each increased our understanding of our solar system, as well as spurred new sets of diverse questions. ![]() NASA has extended both the Juno mission at Jupiter through September 2025 (left) and the InSight mission at Mars through December 2022.

NASA’s Juno Spacecraft reveals Jupiter’s Hot Spots are wider, deeper than thought
New data from NASA’s Juno spacecraft suggests that these “hot spots” are much wider and deeper than anticipated. The findings on Jupiter’s hot spots, along with an update on Jupiter’s polar cyclones, were revealed on December 11th, 2020, during a virtual media briefing at the American Geophysical Union’s fall conference. ![]() These images from NASA’s Juno mission show three views of a Jupiter “hot spot” – a break in Jupiter’s cloud deck that provides a glimpse into the planet’s deep atmosphere. The pictures were taken by the JunoCam imager during the spacecraft’s 29th close flyby of the giant planet on Sept. 16, 2020. (NASA/JPL-Caltech/SwRI/MSSS.

NASA’s Juno Spacecraft data suggests “Sprites” or “Elves” dance in Jupiter’s Atmosphere
It is the first time these bright, unpredictable and extremely brief flashes of light – formally known as transient luminous events, or TLE’s – have been observed on another world. The findings were published on October 27th, 2020, in the Journal of Geophysical Research: Planets. ![]() The lightning phenomenon known as a sprite depicted at Jupiter in this illustration. Jupiter’s hydrogen-rich atmosphere would likely make them appear blue. In Earth’s upper atmosphere, the presence of nitrogen gives them a reddish color.

NASA’s Juno Spacecraft data reveals Shallow Lightning, Mushballs on Jupiter
Other new findings suggest the violent thunderstorms for which the gas giant is known may form slushy ammonia-rich hailstones Juno’s science team calls “mushballs”; they theorize that mushballs essentially kidnap ammonia and water in the upper atmosphere and carry them into the depths of Jupiter’s atmosphere. ![]() This illustration uses data obtained by NASA’s Juno mission to depict high-altitude electrical storms on Jupiter. Juno’s sensitive Stellar Reference Unit camera detected unusual lightning flashes on Jupiter’s dark side during the spacecraft’s close flybys of the planet.

NASA’s Juno Spacecraft gets first ever pictures of Jupiter’s Moon Ganymede
The only moon in the solar system that is larger than the planet Mercury, Ganymede consists primarily of water ice. Its composition contains fundamental clues for understanding the evolution of the 79 Jovian moons from the time of their formation to today. ![]() These images the JIRAM instrument aboard NASA’s Juno spacecraft took on Dec. 26, 2019, provide the first infrared mapping of Ganymede’s northern frontier. Frozen water molecules detected at both poles have no appreciable order to their arrangement and a different infrared signature than ice at the equator.

NASA’s Juno Spacecraft works with Hubble Telescope, Gemini Observatory to examine Atmosphere of Jupiter
A team of researchers led by Michael Wong at the University of California, Berkeley, and including Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Imke de Pater also of UC Berkeley, are combining multiwavelength observations from Hubble and Gemini with close-up views from Juno’s orbit about the monster planet, gaining new insights into turbulent weather on this distant world. ![]() This graphic shows observations and interpretations of cloud structures and atmospheric circulation on Jupiter from the Juno spacecraft, the Hubble Space Telescope and the Gemini Observatory. By combining the Juno, Hubble and Gemini data, researchers are able to see that lightning flashes are clustered in turbulent regions where there are deep water clouds and where moist air is rising to form tall convective towers similar to cumulonimbus clouds (thunderheads) on Earth.

NASA’s Juno spacecraft data reveals amount of Water in Jupiter’s Atmosphere
These are also the first findings on the gas giant’s abundance of water since the agency’s 1995 Galileo mission suggested Jupiter might be extremely dry compared to the Sun (the comparison is based not on liquid water but on the presence of its components, oxygen and hydrogen, present in the Sun). ![]() The JunoCam imager aboard NASA’s Juno spacecraft captured this image of Jupiter’s southern equatorial region on Sept. 1, 2017. The image is oriented so Jupiter’s poles (not visible) run left-to-right of frame. (NASA/JPL-Caltech/SwRI/MSSS/Kevin M. Gill) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Juno Spacecraft discovers new Cyclone on Jupiter
The flyby also marked a victory for the mission team, whose innovative measures kept the solar-powered spacecraft clear of what could have been a mission-ending eclipse. ![]() A new, smaller cyclone can be seen at the lower right of this infrared image of Jupiter’s south pole taken on November 4th, 2019, during the 23rd science pass of the planet by NASA’s Juno spacecraft.

NASA’s Juno Spacecraft maneuvers to avoid Jupiter’s Shadow
Juno began the maneuver yesterday, on September 30th, at 6:46pm CDT (4:46pm PDT) and completed it early on October 1st. Using the spacecraft’s reaction-control thrusters, the propulsive maneuver lasted five times longer than any previous use of that system. ![]() This picture depicts the point of view of NASA’s Juno spacecraft during its eclipse-free approach to the gas giant November 3rd, 2019. The Sun is depicted as the yellow dot rising up just to left of the planet. (NASA/JPL-Caltech/SWRI) «Read the rest of this article» Sections: Technology | No Comments
