Unmanned Spaceflight.com _ Juno _ Juno, perijove 16

Posted by: Gerald Nov 1 2018, 02:52 AM

Here is an 8x enlarged draft of Io in PJ16, #01:



http://junocam.pictures/gerald/uploads/20181101/.

The north polar images have been designed to obtain good data of the northern circum polar cyclones (CPCs), and in order to get data as close to the pole as possible.
We hope to be able to retrieve information about the dynamics of the CPCs.

Due to solar conjunction, the amount of data for PJ16 is limited. The instruments of the spacecraft were looking close to the ground track, without the HGA antenna pointing to Earth during flyby. For JunoCam, the overall focus is on good close-up images. Only few approach and departure images have been taken, actually no approach or departure sequence.

A montage showing the PJ16_6 image in approximately true color/contrast (left) and with the effects of the varying illumination removed and the contrast increased (right):



Areas near the limb at lower left are overexposed since the exposure time was increased to better show details in the dimly lit areas near the north pole.

A subset from the metadata:

IMAGE_TIME = 2018-10-29T20:29:09.835
MISSION_PHASE_NAME = PERIJOVE 16
PRODUCT_ID = JNCE_2018302_16C00006_V01
SPACECRAFT_ALTITUDE = 47405.6 km
SPACECRAFT_NAME = JUNO
SUB_SPACECRAFT_LATITUDE = 81.6117
SUB_SPACECRAFT_LONGITUDE = 137.4188
TITLE = PJ16 North Pole at Minimum Emission Angle
Resolution at nadir: ~32 km/pixel

This is my first pass on Perijove 16, #6 (JNCE_2018302_16C00006_V01). Color is a bit tough due to the exposure mode, but good detail towards the pole.

This is almost vertigo-inducing, but in a good way.

I feel safer than ever in saying that these images will produce important science related – at the very least – to the chromophores in Jupiter's clouds.

Here's a processed and cropped image #0011 (based off Gerald's draft), showing Io setting behind Jupiter's North Polar Hood.



Also playing around with trying to circularize the hyperbolic conic section that we see in the images near closest approach. It looks really unnatural to me, so I've been trying to 'fix' it. I've found a method that might work, here's the result I've gotten. (Base image is a processed version of Gerald's draft #0013.)

https://flic.kr/p/2birqAH

EDIT: Here's another "circularized" image from draft #0017

Interesting approach, Justin.
I like the image with Io just above the horizon.

Thanks, Gerald. Some work from the recent batch of drafts today.

Here's Io rising back above Jupiter's horizon in #0023.



If you look very carefully, the night side of Io is lit by first-quarter Jupitershine.



Here's the full-size, circularized version of #0023.

For PJ16, TDI1 images, I've derived a specific reflectance distribution function (RDF), a 4th degree polynomial over two parameters. The RDF derived from PJ6, TDI2 seemed to reach the limit of its valid domain. The PJ6 RDF has been a 5th degree polynomial over two parameters. http://junocam.pictures/gerald/uploads/20181114/, some of which I've used to derive the polynomial.
The amount of required work, together with rendition times and my own laziness took a few days.

ASTONISHING GERALD! #23

An enlarged and moderately enhanced view of Io from image PJ16_23:



Hints of some of the large scale surface markings are visible despite the very low resolution (~300 km/pixel in the original image data). For context, two computer generated images are also shown.
