Jan 21th 2014 : argelesmer wrote about the Celestia forum to announce the existence
of my new site.
His future addons will be welcome here.
The official site of Celestia is accessible by url (https://celestiaproject.space/).
The site has been inaccessible since the end of April 2023 because
it is hosted in Russia !
With an increasing number of systems required a reorganization of pages ...
it is going on now !
Summer 2014 : the same thing for the vessels...
