The first Juno picture of Jupiter from orbit
The Juno science team have released the first image since the spacecraft entered orbit around Jupiter. I have posted a cropped version on the right, showing only the moon Io. The full image shows Europa and Ganymede as well.
The image was taken from almost 3 million miles away, which accounts for its fuzziness. Expect much better pictures when the spacecraft dips down close in late August.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

Great! Galileo took this image of the Great Red Spot from about 1,500,000 km distance:

Juno will get 300 times closer!
Io is the same size as our Moon, and at the same distance from Jupiter. We could see volcanic eruptions on the Moon with our naked eyes. I read somewhere that imaging of Io is planned. To me it is the visually most fantastic object in the Solar system. A yellow moon with constantly active sulfur volcanoes. It’s sad that no mission to it is even ever mentioned.
Juno is at present 3.3 million miles away from Jupiter and will go out to 5 million miles before returning on its ellipse to Jupiter. S/C is “beneath” orbital planes of large moons and looks back from below. Its velocity is 8,990 miles/hour relative to Jupiter.

Galileo had 0.5 degrees field of view while Junocam has something like 18 degrees. But 300 times closer still beats that. And with 20 years newer imaging technology. The great spot will look greater than ever.
Can’t say it enough times, the animated gifs should be amazing.
