License/Copyright

GPLv2+

Debian

Package was removed from Debian in the ancient days due to bitrot. The upstream code has a new team and active development, using recent libraries. The package can be built under Debian Ok, except for the data/ files.

Debian upstream bug:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=809916

Upstream has not produced any new releases in the last 4 years. In the
mean time, the package is accumulating bugs due to bitrot. It already
wasn't a trouble-free package, due to some quite important resources not
being DFSG compliant.

I do see some of the resources now are CC-by-SA 4.0, a license which didn't exist when the Debian bug was created. So it may be that it can be built happily without DFSG issues using new data files.

Celestia depending on NASA's Spice/NAIF may be afoul of Debian's DFSG because the terms are unique. It isn't really a standard license.
