[edit] Detailed Timeline
Another related question to Yaohua2000: Why do we need the entries in the timeline that gives distances? Is there something significant, there?
I think we can drop the "detailed timeline" entries that are only significant because of a "magic number" in the distance, once they have passed. There is no scientific or other value to them after each date. Anyone opposed? I will clean them up starting April, if nobody objects. Awolf002 15:49, 29 Mar 2004 (UTC)
(Pasted from main page). Please explain why the "50 mill km" entry is needed? This seems to me just to be a "magic" number in km and has no scientific meaning, am I correct? If yes, we should remove them, once Cassini passed them. Awolf002 23:23, 5 Apr 2004 (UTC)
I would see no problem with removing them once they elapse. Their only purpose is to both serve as "filler" and to help give a general idea how fast Cassini is approaching in a more concrete way that x km/hr. I would probably keep the most recently passed milestone, and all the future ones, IMHO. Gregb 23:28, 5 Apr 2004 (UTC)
- Right, I like them as future entries, showing how Cassini progresses. But in six months or so, they are just in the way to find the "good stuff". Let's see what Yaohua2000 thinks. Awolf002 23:32, 5 Apr 2004 (UTC)

- Just make two separated sections, or make the "magic numbers" as a table. Yaohua2000 08:08, 2004 Apr 6 (UTC)
- Uhh.. Table where? Maybe it fits as a table underneath the trajectory pictures on the main page? That seems to tie in better there, than in a time based list, IMHO. Awolf002 12:37, 6 Apr 2004 (UTC)
[edit] The image appears incorrect with my browser
Here is a screenshot:
As above, the image overlayes the text so I cannot read them in my browser. — Yaohua2000 03:46, 2005 Jan 3 (UTC)
Hm, is that safari? It looks ok (there's no overlay) in both IE6 and Firefox 1 on my computer....--Deglr6328 04:11, 3 Jan 2005 (UTC)
Also I made a graph in excel of the huygens distances and it looks very weird to me.
shouldn't this be a straight line if the y axis in in log mode?--Deglr6328 04:11, 3 Jan 2005 (UTC)
- No. It will not straight line even though the y axis in log mode. — Yaohua2000 04:41, 2005 Jan 3 (UTC)
So this is OK then? The data is accurate and this is how it should look?.....--Deglr6328 04:43, 3 Jan 2005 (UTC)
- I think the y axis is already in log mode in your chart. I'll make something about Huygens's distance related to Titan after finish my lunch. — Yaohua2000 05:04, 2005 Jan 3 (UTC)
-
- (lunch?! where are you?) Yes the Y axis is logarithmic. I just think a chart or graph would represent the information much better than a big list.--Deglr6328 05:15, 3 Jan 2005 (UTC)

- Well, I'm from Tianjin, which lies 39.1° N, 117.2° E. The chart on the right may be the one you want. — Yaohua2000 05:33, 2005 Jan 3 (UTC)

- Neato. Yeah that looks fine to me.--Deglr6328 05:39, 3 Jan 2005 (UTC)

- My browser (Firefox/1.0) still shows the picture overlapping the numbers. What's up? Awolf002 13:13, 3 Jan 2005 (UTC)
[edit] Detailed timeline of Huygens mission
This section has:
- The data used in this section has been out of date, a updated version of ephemeris from ESA was available yesterday.
I changed this to 2005 Jan 7, but what is the ESA reference for this new ephemeris, and how does it affect the times? Are the changes solely due to to the change to the Titan 5 and 7 encounters described in the December 3 Press release (extracted here)?
- The altitude of Titan 4 - currently at ~2500 km - lowers slightly, and timing changes to all encounters exclusively from this change are less than one minute. The navigation team will be releasing a new spacecraft ephemeris shortly.

[edit] Pre-launch
Is there any information available about events prior to the launch, such as the conception of the project? -- Greg K Nicholson
