Breaking News!! - Juno Probe sends back first home movies of Jupiter!!

[ArMaP]

did you find it odd that at 5:53 in the video the exposure goes through the roof to the point where the moons are leaving trails.. but I wont call it smoke just yet

Yes, I noticed that, but as I don't have any information about how the video was made or how the camera works I didn't comment on that.

I wonder why they thought to adjust it, the initial exposure was fine , I could almost make out rings.

and how did they do so , given the lag in time ?

and why change it to a terrible setting , given that they had visual feedback to decide on an adjustment?

just seems a little co incidental, we see  unobserved behaviour in the Jupiter system, and suddenly the camera operator returns to pre school ..way to spam them buttons and hope nasa

Actually that over exposed segment is identical to other clips, so I don't think it's a cam operator error.

I got that from a news program about Juno and included it, not sure if NASA did it or not.

Somebody got creative with the raw clips and did that so we could observe the light trails left behind as well as the dark ones.

That's what makes the orbits stand out so clearly.

It's my favorite clip.

ahh ok , the usual confusion from Nasa then , cause a simple title was just too telling

should expect it really

My fault really. I threw it in the middle there and didn't know what to title it - 'unknown processor footage?'

The news program didn't title it is the primary problem. I'm sure it will come out eventually.

I searched around for all the best hi- res clips I could find for the OP video, and found the one with tracers at 8:30 here -

ahh , I thought it was something edited by Nasa's PR team , fair enough , at least we know that there's been no shenanigans.

I think ..

where does the unusuality lie here then ?
bar them trails

Well NASA's current thinking on Calisto based on previous probe scans is that it does not have an iron core.

That rules out the theory of magnetic forces battling with gravitic forces causing the odd jumping up and down seen in it's orbit.

Still no word from NASA on what's causing this.

Still no word from NASA on what's causing this. 

That's because they would have to guess.

[A51Watcher]

"Arguments for an ocean came from two pieces of evidence, according to NASA.

First, scientists saw regular fluctuations of Callisto's magnetic field as the moon circled Jupiter, which implied there were electrical currents within the moon stimulated by the planet's magnetic field.

That current had to conduct from somewhere, which led to the second piece: due to the rocky surface and thin atmosphere, a likely explanation would be a salty ocean under the moon's surface."

there seems to be no reference to the blinking , is there no where else on the net where it has been referred to ?

From what I have seen, the problem with the video is that any person can make a video with the photos NASA published, and they even asked for people to do that, so what we are seeing is somebody's work done with the official photos. You can download the original photos and see for yourself or make your own video.

The official photos are here.

Well let's have a look see then. Here are the official photos from the site you linked, strung together as a movie with no processing performed, display frame rate is 15 fps -

APPROACH MOVIE PROCESS LEVEL 1
2016-06-12 00:10 UT
NASA / SwRI / MSSS
© PUBLIC DOMAIN
Mission Phase : MOVIES
All images were cropped to 800 x 400 pixels (width x height) and color-registered.  No form of contrast-enhancement was applied to these images.  No partial images were processed.




APPROACH MOVIE PROCESS LEVEL 2
2016-06-12 00:10 UT
NASA / SwRI / MSSS
© PUBLIC DOMAIN
Mission Phase : MOVIES
All images were cropped and enhanced to 1280 x 720 resolution (width x height) and rotated to a North-up orientation. Contrast-enhancement was applied for moon visibility, along with noise removal and correct color registration.  No partial images or images with a TDI of 1 were processed.




Nasa did say at the news conference that Callisto has a lower Albedo than expected and they will be investigating that.

So we do still see blinking on the official photos (use the slow motion option on the youtube player if it is not apparent), with the Contrast-enhancement done by Nasa .

And of course the wobbling is still there.
