Nope, its not. Its just because i named this account (and every other one i use) after the anime Gurren Lagann, which i keep rewatching.

Yes i read it - but it looks like you two are actually fighting though...

Could someone create a full xyzv of the Rosetta mission? The only ones we currently have go all the way up until it approaches the comet. It would be very nice if someone could do this. Also, I found data from HORIZONS, so that would be where to find the orbital information.

Ok, SpaceFanatic64... let's try...

@SpaceFanatic64... but about WIND spacecraft... you said that there orbital data for it on HORIZONS... but I did not found.. :think: So I will start (during 48 hours) the launch of this spacecraft to the Celestia space to the heliocentric orbit which I will prepare by myself, till we find original orbital data for this spacecraft...

Hm, that's strange. Maybe I thought I saw it on HORIZONS, but I guess I must've confused it with some other spacecraft. I'm sorry, my mistake.

@SpaceFanatic64.. No problem.. I guess that together we will find the orbital data for the WIND... :smile:

For WIND, the celestrack archive sent me this file

There is only once the 2 usual lines.


:hi:

Added after 3 minutes 45 seconds:
on https://sscweb.gsfc.nasa.gov/cgi-bin/Locator.cgi, we find WIND but I think it is necessary to interpret the types of coordinates proposed because they do not correspond to those used in Celestia.

Gironde... but from this 2 lines I can see that it is for the geocentric orbit...
I read... the orbital data for...
Epoch 1994-11-01 11:59:59...
Inclination 28.749...
Ascending of Node 2.372...
Eccentricity 0.9728298...
Argument of Pericenter 30.436...
Mean Anomaly 1.35...
Rotations per day 0.07309491

from this I calculated...

Epoch JD 2449657.999988
SemiMajor Axis 241 626 km...
Period 328 hours 20 minutes 24 seconds (19700.40 minutes.)
Pericenter 187 kilometers...
Apocenter 470309 kilometers...

but this spacecraft changed the orbits many times... ok, we can use this data, till we will find something else...

Toutatis,

Sorry for the off-topic, but how do you make the orbit only the selected object and not all spacecrafts ?.
I see the orbit of the selected object in red and the orbits of all the other spacecrafts in light gray.

Diigg,

in the rendering options, you have to check the orbits in general but not those of spacecraft; so you only display the orbit of the selected object

Toutatis has a pending model; he will certainly be better than mine. In the meantime, here is a xyz file
