New Horizons Jupiter Encounter Options

[NMRguy]

Thanks again, Emily. It's really nice and very easy to follow, and it gives you a clear idea of what cameras/spectrometers will be used in tandem. Keep up the great work!

Thanks for the preview Emily, but I couldn't help but be reminded of this Far Side cartoon:

At that, the dog understands a lot more than my daughter does

The "blah blah" is gone; I've uploaded my update, with some illustration and some more explanatory text. Check it out! It'll probably get tweaked one last time before I blog it. Please feel free to send me an email with any comments or suggestions.

I think the pics from Dave's simulator are a master stroke. Whoever thought of adding those is a genius.

In all seriousness - it takes Johns XLS, and makes it suitable for public consumption - great work.

I don't know how good the New Horizons trajectory is for Celestia, but if it's any good - I'll do a movie of it.

There are a few more images posted on the SOC page, up to Jan 24 and a range of 57 million km. Albedo features are slowly becoming resolvable on the moons. I wonder why the north on Jupiter is not up (or left) in these images, but somewhat tilted, does the S/C use the celestial north pole instead? A couple of frames targeting a specific moon do seem to have Jovian north aligned to a spacecraft axis on the other hand.

EDIT: Curious, the images have disappeared again. Oh well, they'll be back.

Probably just the attitude of the spacecraft when imaging - it doesn't really matter Perhaps there is some sort of alignment involved for the other instruments to sweep across the disk?

Is it possible that we are starting to see details to a point where we can already identify some larger volcanoes?...
Hey...What do I know? This may be even not Io at all...
But it looks like it and if it is...is it possible that some new volcanoes have appeared since the last visit?...

If I'm wrong and this is Callisto or some other Moon please give me some discount, I've been inside an abyss for too long...

It seems it should be possible to combine LORRI detail images with MVIC color. MVIC's field of view is 20 times broader than LORRI's, but its CCD is almost 5 times broader, so in fact MVIC's resolution is only four times coarser than LORRI's, which is not bad.

We'll be doing some MVIC/LORRI combinations, but not many at Jupiter, because we can't actually use MVIC much at Jupiter- it's too sensitive to be useable on the day side of Jupiter or its moons, so the images will saturate. It's also fairly data-intensive due to the large field of view- we don't yet have the capability to store only the rows containing the target. But we will get a couple of images of the Jupiter terminator, several scans of Io's night side, and we'll include an MVIC scan in the Io/Europa conjunction Kodak moment- maybe we'll catch some blue plumes off the limb and make a nice LORRI/MVIC combo image there.

But sure looks like it...
Sharpened version

[Alan Stern]

That's cool. Seems convincing on first look. Spencer-- You're Dr. Io. What do you think?

I've a feeling these are artifacts resulting from the sharpening process, unfortunately. Ustrax's images did prompt me to go back to our orignal data and look at the Io images more closely, but so far I haven't been able to confirm those features. Not quite done though- I'll look a bit further.

Is that even Io? Check out my post on Io earlier: http://www.unmannedspaceflight.com/index.p...ost&p=82165

If ustrax has the right hemisphere according to his reference image, the most prominent feature in the image should Bosphorus Regio, which should appear bright near the center of the disk. Media Regio oddly appears brighter than Bosphorus, which doesn't make any sense.

Spencer-- You're Dr. Io.

On his way into work does he sing, "Io, Io, it's off to work we go!"

Sorry I had to say it before Bob Shaw did.

[Phil Stooke]

No, it's "Io my soul to the company store"

That's a more catchy description than the one where the 1970's era newscaster pronounced Io as "ten."
