Celestia Forums

The stuff looks pretty current and in fact, when you click on the planets, it starts up Celestia like a script..

http://learn.arc.nasa.gov/planets/

Is there some reason you didn't post this to the Celestia in Education Forum?

At any rate, that's where I moved it

Actually, that is a very old site. Well, old in network years (3 years?) The project had very limited funding and did not get renewed.

that's for the tidbit.. I'll delete the initial post...

Does anyone know what their custom add-on is or where it can be retrieved? I'm trying to figure out of the site is at all usable....

The NASA Web pages which used to contain the Addon are long gone. Sorry.

[edit]
However, the WayBack Archive site seems to have a copy. I don't know how complete it is, though.

I agree that learn.arc.nasa.gov/planets/ web site looks like Celestia but the learn.arc.nasa.gov/planets/ has better design and is easy to use.
