Bjorn Jonsson can you share flyby distances for rev 012 with us ???


PLEASE

Posted by: Bjorn Jonsson Jul 20 2005, 08:17 PM

Mimas: 63,000 km Phase=58 deg
Enceladus: 387,000 km Phase=105 deg
Tethys: 257,000 km Phase=108 deg
Dione: 152,000 km Phase=77 deg
Rhea: 212,000 km Phase=97 deg
Titan: 840,000 km Phase=62 deg
Hyperion: 1,289,000 km Phase=99 deg

Several Voyager-class flybys this time, including the closest Mimas flyby of the entire mission.

Poor Mimas.

Please tell cassini will get images of all these NTs?!?!?!

You can guarantee it for Mimas For the others, I think Rhea might get some images. Dione as well.

I was fooling around with some Dione images, and I saw an odd feature...it seemed like a large, shallow, irregular pit. Will Cassini image this area at high resolution?

Got a few more images of Rhea added to my map. This includes the Rev 12 flyby as well as the previous one. As always, I may still be doing some further touchup.

Great work Steve!

Have you considered adding polar projections?
Also is there a Titan update anytime soon?

Greetings Decepticon,

I'll have to check whether there's a simple way to add an automatic conversion to polar projections in my image processing software. Meantime, perhaps Phil Stooke might drop in from vacation again? He did a good job reprojecting some of my other maps.

As for Titan, I've been pointing to Fridger Schrempp's latest map (adding in turn to some of VP's maps) on my web page. I suppose the more recent imagery shows Peanut Lake, near the south pole. Actually though this "lake" shows up surprisingly well even in that early map. Is there other recent imagery that would represent a major addition to this map? The various methods of image enhancement that have been used on Titan present a challenge to making a reasonably uniform looking map.

By the way, I like the original avatar that you have returned to...

More than meets the eye!

Can't a fellow sit on a beach for a few days without being pestered to make a polar projection? On the other hand... I do seem to sneak away to the computer a bit too frequently to complain, don't I? Actually, this trip to Vancouver is more of a 'working vacation'. My next trip to the fair city of New Sarum in September will be a lot more like a real vacation. I will really be incommunicado then.

I can't reproject right now because I'm just using library computers without my fave software. But later in August I could make some polar maps.

Phil

New Sarum? Do you mean Salisbury, or is that somewhere in Canada?

I created this using Titan24
settings: orthograghic projection; nightside darkness 0% ; centered on long 330, lat -90

You can create the same for other moons using the images on Steve's site by downloading them to the sourcemaps folder, you may need to downsize some of the larger ones first.

WOW Very cool.
