Juno Completes Perijove 6

Juno has completed Perijove 6, the sixth orbit around the planet Jupiter.  The image above is from the previous close pass and was processed by J.P. Hershey one of many citizen scientists processing the images from Juno data.

This data is available to anyone; everyone is encouraged to try their hand at processing and submit their entries.  You can too, just go to NASA’s JunoCam page.  I have made some rather primitive attempts with rather primitive results.  The problem is my knowledge of the program I am using (The GIMP), I am more used to Photoshop CS.  The newest images, from Perijove 6 are already downloaded and available.  Interesting, the images are down and ready before too much of the details of the pass are.  Probably this is due to the pass timing with the weekend.  All seems good, I’m sure we’d know by now if something was amiss.

So, undaunted, I have downloaded a set of images and am trying again.




Jupiter’s Pearl

This image, taken by the JunoCam imager on NASA’s Juno spacecraft, highlights a swirling storm just south of one of the white oval storms on Jupiter.

The image was taken on March 27, 2017, at 2:12 a.m. PDT (5:12 a.m. EDT), as the Juno spacecraft performed a close flyby of Jupiter. At the time the image was taken, the spacecraft was about 12,400 miles (20,000 kilometers) from the planet.

Citizen scientist Jason Major enhanced the color and contrast in this image, turning the picture into a Jovian work of art. He then cropped it to focus our attention on this beautiful example of Jupiter’s spinning storms. — NASA

I spent a good bit of time yesterday fooling around with JunoCam images. I put GIMP 2.8 to do the editing. I’m still in the learning stages, thankfully the GIMP is similar to Photoshop so that is helping but things will take a bit of time to get right.

I like this image, looks almost a water color.

The Magnificent Dark Spot

What are those dark spots made of? Where’s Captain Kirk or Doctor Who when you need them?

Seriously, incredible work by Citizen scientist Roman Tkachenko — the quality is top notch! I’m going to follow his work on the new images coming in from Juno very shortly.

The image above was downloaded from the 02 February pass. We will have images very shortly from the 27 March pass which was successful and was be only 4400 km / 2700 miles above the cloud tops of Jupiter.

We’ll be watching JunoCam for the latest.

Today is Perijove 5

Perijove 5 is today at 08:53 UTC / 04:53 ET.  That is when the Juno spacecraft will make a close approach to the planet Jupiter on this orbit if you didn’t know.  If you have been following the mission you know the orbital period was going to be much shorter but was changed after a engine control valve did not react as expected.

The current plan is no change to the shorter orbit.  Good idea, the science data is apparently just as good, so why risk a problem.

JunoCam targets this time around are:

Double SEB
Trevmation’s Dark Spot
The Big Red Stripe
String of Pearls + Between the Pearls + An Interesting Band Point
STB Spectre + The White Solid
Covenant 151016 as part of the polar timelapse sequence

You can get a preview of these on the Juno site.

Personally I’m all in for The Big Red Stripe!

The image above is from the JunoCam site observed by Ceres-00.  See it here.

Jupiter Cloud Detail

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.

This Week @ NASA

Featuring the Juno’s  fly-by of Jupiter passing just 4345 km / 2700 miles above the clouds.


I still am working on the image processing thing, I’m having difficulties thanks to an apparent lapse of organization. LOL, meaning I can’t find the power supply to the laptop with photoshop.

The Little Red Spot

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.

A Crescent Juipter

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.

JunoCam’s raw images are available at for the public to peruse and process into image products.

Juno Sees a Pearl on Jupiter


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.
