The Juno probe has sent back time- lapse home movies from it's arrival at Jupiter!!  8)  8)  8)

I note that the first and second moons display smooth circular orbits, while the third and fourth moon in particular, display an odd jumping up and down during their orbits.

I will be very interested to hear what forces of celestial mechanics are causing this.

Is it a gyroscopic effect from the spinning moons, or leftover orbital waves from when it fought capture by Jupiter? 

Hmmm  8)

is it me or are those moons blinking ? what would cause such loses in magnitude as they orbit Jupiter ?

Well they all blink when they eclipse, but the 4th one blinks in places where it should not, i.e. other than behind Jupiter from the sun.

So yes that is odd as well.

And yeah the 3rd one blinks a lot as well.

there also seemed to be a little light follow parallel to the top edge of the screen, it comes into view as the rocket banks slightly.. something in earth orbit , but to me it looks like its movements is more than rocket menouevers..

ill get the time code..2:20 onwards to 3:04 when the graphic appears

Yeah the one that moves left for a bit then goes downward.

Probably just ice crystals!  ;)  ;D


eta: Maybe that blinking is other planets closer in to the sun getting in their way to the sunshine?

The blinking is strange, could it be the result of the rotation of the moons?

doubtfull , how does rotation effect reflectivity ? ide like to say it part of the camera's setting , but it would be noticeable on Jupiter too, but im not seeing it

have they proffered an explanation yet ?

If the moon's surface is not all the same it will have different reflectivity (I think albedo is the right word) in different areas.

I thought of that too, slight changes in the camera settings could make a difference, specially in the more dim objects, while Jupiter would remain mostly the same.

Anyone asked?

Since this first footage was interrupted for whatever reason, I am hoping we will get continuous footage of the moon's orbits in the weeks to come.



The imaging will have to begin right away, since the Junocam is the only instrument not inside the titanium protection box that houses all the other science instruments from the intense amounts of radiation present.

The Junocam is expected to fail mid- february due to this radiation.

Also these first two 53 day orbits are our only opportunity for wide angle shots. 

The 14 day orbits may not be able to get all 4 moons in frame -

Ahh! Good news!

"Juno's camera -- JunoCam -- also was shut down during orbit insertion, but it is back in action, taking long-distance shots that will be combined into a so-called "marble movie."

http://www.cbsnews.com/news/juno-heads-back-toward-jupiter-instruments-at-the-ready/


During the post orbital insertion news conference the mission director responded to a question about any surprises by saying the outer moon appeared much dimmer than they expected, and plan to investigate.

But no mention of the odd oscillations we see during orbit.

In watching the tracer sequence the oscillations remind me of oscilloscope display patterns, or even a heart beat monitor.

Even the first moon with the most smooth orbit of all, still displays some slight oscillations as well, with each moon outward displaying this same behaviour more pronounced the further they are away from Jupiter.     

eta: So is gravity restraining their urge to jump around or the root cause of it?

Still waiting on an explanation for this.

maybe Jupiter is emitting something to cause this variation, I need to look at this again to see , but did you notice any timing between the moons brightness,.. synchronisation etc etc ? maybe even tapping out a tune :D

I am going to knock out an enlarged version centered on the fourth moon with tracers to see what shows.

So far every look at Jupiter all the way through it appears steady as she goes.

So nothing obvious as to what's causing it.

As the mission director put it, until now.. we have only been able to imagine celestial harmonic motion, or create computer simulations, but now seeing an actual look at it in motion is quite another thing.

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 :D

should be interesting .. whilst you in your video suite , drop in a filter after 5:53 , see if they've tried to disguise the blinking with overexposure :D

let me know , ill do a full rendering if it turns out to be true

share the load like :D
