This is a question for someone from the New Horizons team (Mr. Stern?): Could you publish (pdf) a detailed Jupiter encounter timeline (e.g. which instrument does what at a specific time, spacecraft turns, SSR data volume etc.)? Like the preliminary encounter document posted here last summer. Your flyby press kit is, well, for the general press smile.gif, but not very detailed in respect to the encounter sequence. Thank you.

I enjoyed watching the press conference live. Lots of great info and insights. And it was quite a nice kudo to see the welcome mat for amateurs as they pointedly encouraged suggestions for "kodak moments" and other observations

Plus brand new images and animations, most of which are available here.

Not to moan at a joyous time, but damn that luck of Callisto and Ganymede being on the opposite side of Jupiter! Callisto could have been a huge looming disc for NH, and it ended up being almost worst-case faraway instead!

That's a good question. It would seem unlikely that such a graph would be anything but spacecraft time, which would be UT, but I don't actually know.

I think we're using UT (and spacecraft time, not Earth received time which is 45 minutes later) in all our graphics unless otherwise stated.

Umm... is there a link to the native resolution version of that cool Jupiter and Io image? What's the point of providing a magnified "hi-res" image like that? If one were writing a wish-list, I'd put lossless PNGs as well, but let's not get greedy here biggrin.gif


We should be posting all the images in JPEG format and native resolution on the NH web site in a few days- stay tuned!

Regarding making more observations at Jupiter than at Pluto, mostly it's just because we can- the Jupiter system is so much bigger so there's a longer period in which we can get useful data. But as Alan said, it's also a great way to push the system so we can expose and fix any weakenesses.

Finally, here's a recent timeline spreadsheet for you to chew on- this is one of our working documents for planning the encounter. It's not quite the final version- there have been a few timeline tweaks in the couple of weeks since this version- but it's pretty close. The data volumes and numbers of frames per observation are early estimates and shouldn't be relied on, but give some idea of what's planned.

Thank you so much John!! I'll see if I can produce a slimmed-down timeline to post on our website.

What are those Callirrhoe opnavs? Has New Horizons actually sighted its first non-Pluto KBO already? ohmy.gif

Callirrhoe is one of the newly discovered small outer satellites of Jupiter- we looked at it because it's about the same brightness as our KBO target is likely to be when we first pick it up on approach in 2019 or whenever. So it was a test of our ability to pick up a very faint moving target using long exposures.

A nice handfull of Kodak's - I'm really proud that UMSF was able to contribute in some tiny way - this will rank up there with the MOC Deimos observation in terms of wow factor.

I think these are Kodak moments where the time in MJD ties back to suggestions by hendric.

Line 031 54117.06319 Double shadow Transit
Line 034 54124.19514 Double shadow Transit
Line 110 54159.48961 IO Emerging from behind Jupiter
Line 143 54161.43332 Io/Europa conjunction
Line 165 54163.17200 Callisto emerging from behind Jupiter

Awesome. If I'm counting correctly the spreadsheet says these will take up 251Mbits of LORRI raw storage. Wow.

These shots represent around 0.5% of the total data return for the mission (in terms of bits of data returned). If you were to price all the bits returned by the mission equally then you could argue that these shots are worth around $30 million for the set.

I take it we're going to be getting high quality prints and expensive frames for them then?. smile.gif

I'll sell you all of the black pixels now for only $300.

A brief word to all the NH lurkers on UMSF:

Keep up the good work! We're with you...

And post them images real soon now, OK?
