Juno's first picture in 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.

    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.
