Hey all

I know yesterday I said that I wouldn't be posting any more new models for a bit, but I have had Nozomi 99% finished for about 2 weeks, so it didn't seem fair to leave it sitting idly there for another 3...

Like Ulysses, it has large magnetometer booms (4 in this case), which I have an option of downloading or not. It also has the now famous, crinkly aluminium foil effect.

Here are some screenshots (of the one without booms):

And the model with booms on (ambient light is on full so you can see them):

As always, the site is http://homepage.eircom.net/~jackhiggins/celestia/

Enjoy!

Jack, you're a bloomin' marvel. Great as usual.

Many thanks...bh.

Jack, sorry about this one... I am the Homer Simpson of Celestia... I just can't get on with these xyz....or what evever. They just don't seem to work for me.

Any chance of a simple ssc with orbital data just to slot into extrasolar or solar.ssc?

I've got your Uleysses and new Nozomi models but I have to give them a asteriod type orbit to view them! (I must try a bit harder here).

Any tips on this one? (you seem to know what you're doing here).

Regards...bh.

bh,

Jack's zip file includes the xyz trajectory for Nozomi. It's about to make a graviity-assist flyby of the Earth next month, which will make a major change in its orbit. It's scheduled to reach Mars in January.

With that caveat, here's an elliptical orbit definiton good only for today

and here are the orbital elements for 1 Sept. 2003, while it's coasting between Earth and Mars.

Selden...many thanks for your orbital data on this one.

All the Japanese spacecraft are given prelaunch names like Planet-A, MUSES-B, Planet-B etc, and are then given their official names later.

Planet A studied Halley's Comet, and was also called Susei (meaning comet).

MUSES-B was a radio astronomy satellite, and was also called Haruka (meaning far away)

Planet B is Japan's first Mars orbiter, and is also known as Nozomi (meaning hope)

The best site for spacecraft mission info & images is http://nssdc.gsfc.nasa.gov/

What problems do you have when using xyz's?

Jack..I'll post some screenshots of my non working xyz..soon.
