I've heard that someone might be demoing it live, twice, on the first NASA TV broadcast tomorrow evening, and that there might be a frickin great big camera on top of his console staring him in the face. ph34r.gif

(and if I do say so myself, the C/A looks really awesome in EotSS - took some work by a very very clever programmer called Jon to get the camera to flip from periscope to off periscope. He's actually programmed the spacecraft to do faux-auto-nav based on the provided trajecgories for Stardust and Tempel 1. Plus - our 3D guy, haivng produced a BEAUTIFUL Stardust spacecraft, went and created a brailliant Tempel 1 complete with stuff seen by Deep Impact ( grey ) stuff not seen ( blue ) and the hoped-for crater ( red target )

If I do say so myself, it's fairly cool.

Oh and don't - whatever you do - look at the tutorials page.

Don't have any chocolate the night before. Never fails the day you are going to be on television ...

Of course "what time?" depends on where you live on our worldwide forum.

The schedule is always available on the NASA website...or just a Google query away.

I know, just being lazy, also I don't actually frequent the nasa site much, and would have had to guess where the tv schedule was......

Bottom line is it's on too late for me....I need to be zzzzzzzzz at 11:30 EST. Oh well.

I don't know if these updates all came in at once, or if changes in the page format fooled feedity:
http://stardustnext.jpl.nasa.gov/mission/m...tatus11_q1.html

Some excerpts.

QUOTE
Frday, Feb 11. E- 3days
The opnavs received today are all at 0.25 pixel quality, and have moved the solution since yesterday’s opnav solution. The science team believes that we are seeing the nucleus signal starting to come through, and these latest opnavs are the best indication of the nucleus location. The maneuver design is being finalized, and will be around a 170 km maneuver.


QUOTE
Sunday Feb 13, E-1 day
The overnight activities taken by the flight team went very well, and the final OpNavs taken at E-42 hours were successfully acquired and downlinked.
The navigation solutions were finished this morning, and they show that the predicted delivery is within the ‘green zone’ of the delivery chart. The nominal flyby point is at 191 km from the surface of the comet with a 11km uncertainty radius. The current Time of Closest Approach estimate is still around 04:40 UTC on February 15 (20:40 February 14 in Pasadena). Based on these discussions and updates, the following decisions were made, with full concurrence between the PM and PI:
- No TCM 34 will be executed


QUOTE
Monday Feb 14, E-21 Hours
The spacecraft team has just completed the final commanding prior to encounter.
This included the encounter sequence and the supporting files that were built this afternoon with the final trajectory and time of arrival estimates.
Most fault protection has now been disabled, and the Mission Phase Bit has been set to ‘Encounter’. From now on, a safe mode entry will trigger the autorecovery sequence that will attempt to recover the spacecraft autonomously and restart the encounter sequence


Crazy! But after the worry, optical navigation got them where they wanted, with a TCM to spare.

So there was just a large solar flare. Did that send high-energy particles towards Stardust, and if it did, when do they get there?

You'll want to re-start EotSS later ( about 8.30pm Pacific - just when the broadcast starts ) - as we'll have adjusted for the updated C/A time.

And that flare was on the Earth side of the sun ...and using EotSS (sorry to plug it so much biggrin.gif ) you can see Stardust is on the other side of the Solar System.

I used EotSS this weekend to wash my car and it did a marvelous job. It also repaired my grandfather's broken watch. I only wish I had discovered this incredible tool sooner. It really has changed my life.

That sometimes happens before your GFX card has finished initializing - give it time. If it doesn't clear after a few seconds, then...er.....it's still a beta.

NTV will be cutting to Eyes... live during the flyby

EoTSS running sweet here on Win7...nice view!

Steady as she goes, Mr. Ellison! tongue.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
