The way this image was processed gives a good look at the cloud structure, nice work. You can see the original version of this and other submissions at NASA’s JunoCam site.
NASA’s Juno spacecraft skimmed the upper wisps of Jupiter’s atmosphere when JunoCam snapped this image on Feb. 2 at 5:13 a.m. PT (8:13 a.m. ET), from an altitude of about 9,000 miles (14,500 kilometers) above the giant planet’s swirling cloud tops.
Streams of clouds spin off a rotating oval-shaped cloud system in the Jovian southern hemisphere. Citizen scientist Roman Tkachenko reconstructed the color and cropped the image to draw viewers’ eyes to the storm and the turbulence around it. — NASA
Here’s an image from the latest Juno-Jupiter encounter. I fiddled with this image a little, most of the processing was done by Gerald Eichstädt. I ended up only darkening it up a bit to bring out the color more; Gerald did a fantastic job and I actually lot a little of the image. Fun trying though, give it a try for yourself at the JunoCam Image Processing page.
Below is a Juno spacecraft image of the northern part of Jupiter at just 16,000 km / 10,300 miles. The image was taken during the 11 December 2016 fly-by.
Juno is on a 53.4 day orbit and that makes the next close approach or perijove in just a few days on 02 February 2017.
All raw Juno images can be seen at the JunoCam site and the public is encouraged to download and process the images and even share your images back.
This particular image is from NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstaedt/John Rogers. Very nice work!
Here’s the NASA caption:
This stunning view of the high north temperate latitudes fortuitously shows NN-LRS-1, a giant storm known as a Little Red Spot (lower left). This storm is the third largest anticyclonic reddish oval on the planet, which Earth-based observers have tracked for the last 23 years. An anticyclone is a weather phenomenon with large-scale circulation of winds around a central region of high atmospheric pressure. They rotate clockwise in the northern hemisphere, and counterclockwise in the southern hemisphere. This Little Red Spot shows very little color, just a pale brown smudge in the center. The color is very similar to the surroundings, making it difficult to see as it blends in with the clouds nearby. Citizen scientists Gerald Eichstaedt and John Rogers processed the image and drafted the caption.
One of the nice images coming from the Juno spacecraft. The Juno mission invites people the try their hand at processing the raw images of Jupiter, see the link below.
Description from NASA:
This image of a crescent Jupiter and the iconic Great Red Spot was created by a citizen scientist (Roman Tkachenko) using data from Juno’s JunoCam instrument. You can also see a series of storms shaped like white ovals, known informally as the “string of pearls.” Below the Great Red Spot a reddish long-lived storm known as Oval BA is visible.
The image was taken on Dec. 11, 2016 at 2:30 p.m. PST (5:30 p.m. EST), as the Juno spacecraft performed its third close flyby of Jupiter. At the time the image was taken, the spacecraft was about 285,100 miles (458,800 kilometers) from the planet.
Happy to see Juno made it through the close encounter with Jupiter!
This is one of the images returned from the spacecraft. I’ve cropped and tried to enhance the features of the original, seems to have worked out nicely – click the image for a larger version.
I’ve included the original as a link in the caption released with the image below (it will also explain the odd angles in my cropped image:
This image, taken by the JunoCam imager on NASA’s Juno spacecraft, highlights the seventh of eight features forming a ‘string of pearls’ on Jupiter — massive counterclockwise rotating storms that appear as white ovals in the gas giant’s southern hemisphere. Since 1986, these white ovals have varied in number from six to nine. There are currently eight white ovals visible. Since 1986, these white ovals have varied in number from six to nine. There are currently eight white ovals visible.
The image was taken on Dec. 11, 2016, at 9:27 a.m. PST (12:27 EST) as the Juno spacecraft performed its third close flyby of the planet. At the time the image was taken, the spacecraft was about 40,000 miles (24,600 kilometers) from Jupiter.
JunoCam is a color, visible-light camera designed to capture remarkable pictures of Jupiter’s poles and cloud tops. As Juno’s eyes, it will provide a wide view, helping to provide context for the spacecraft’s other instruments. JunoCam was included on the spacecraft specifically for purposes of public engagement; although its images will be helpful to the science team, it is not considered one of the mission’s science instruments.
This composite image depicts Jupiter’s cloud formations as seen through the eyes of Juno’s Microwave Radiometer (MWR) instrument as compared to the top layer, a Cassini Imaging Science Subsystem image of the planet. The MWR can see a couple of hundred miles (kilometers) into Jupiter’s atmosphere with its largest antenna. The belts and bands visible on the surface are also visible in modified form in each layer below.

If you were wondering where the new pictures of the clouds of Jupiter are, the Juno spacecraft encountered some sort of issue just hours before reaching perigee to the planet and the computer rebooted and no data was collected. No worries all systems are apparently working normally.
NASA’s Juno spacecraft entered safe mode Tuesday, Oct. 18 at about 10:47 p.m. PDT (Oct. 19 at 1:47 a.m. EDT). Early indications are a software performance monitor induced a reboot of the spacecraft’s onboard computer. The spacecraft acted as expected during the transition into safe mode, restarted successfully and is healthy. High-rate data has been restored, and the spacecraft is conducting flight software diagnostics. All instruments are off, and the planned science data collection for today’s close flyby of Jupiter (perijove 2), did not occur. Continue reading →
The Juno spacecraft is about to make a close pass at Jupiter (19 Oct) and there was scheduled a engine burn in order to change the spacecraft’s orbit. The burn is not going to happen as scheduled. There is an issue involving the engine being investigated and more time is needed for evaluation. The “burn” was going to change the orbital time from 53 to 14 days and of course it will remain at 53 days.
“Telemetry indicates that two helium check valves that play an important role in the firing of the spacecraft’s main engine did not operate as expected during a command sequence that was initiated yesterday,” said Rick Nybakken, Juno project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. “The valves should have opened in a few seconds, but it took several minutes. We need to better understand this issue before moving forward with a burn of the main engine.”
The good part of the story is now the mission team is going to have ALL the Juno instruments active for the fly-by.
