* 2020-08-20 : Scott Hudson is the author of the following digital asteroid models:
models/bacchus.*
models/castalia.*
models/geographos.*
models/golevka.*
models/kleopatra.*
models/ky26.*
models/toutatis.*

His original license was as follows (taken from http://users.tricity.wsu.edu/~hudson/Research/Asteroids/index.htm):

   The digital asteroid models available on this page are in one sense the "final deliverable" 
   from this research program. I make them available here for scientific research, educational, 
   and private uses. In other words feel free to use these models for any non-commerical, 
   non-profit use. Do not use them for any commerical purpose without written permission from 
   Scott Hudson (toutatian@yahoo.com) and/or NASA.

I reached out to Scott via email and he waived the commercial use restrictions on his models (and noted that
they are being distributed by NASA directly under their standard license terms). A copy of this email is included
below.

Tom,

I've been gone for most of the summer, and am just now seeing your email.

I have no problem with these models being used for commercial purposes. I 
originally put that "non-commercial use" statement there because these models
were developed with NASA funding, and I wasn't sure what NASA policy was
at the time. That is no longer a concern. The models are available at many
repositories, including the following two:

Subject: License on your asteroid models

Professor Hudson,

In researching the licensing of Celestia (https://github.com/CelestiaProject/Celestia), 
I have noticed that it includes copies of your asteroid models, 
originally found here: http://users.tricity.wsu.edu/~hudson/Research/Asteroids/index.htm

Celestia is under the terms of the GPL license, which would seem to conflict 
with the license on your asteroid models because of your restriction on commercial use.

Would you be willing to amend your licensing for these asteroid models to permit 
commercial use? If you can do this, it will resolve the licensing issue within Celestia. 
If not, these asteroid models may need to be removed from some distributions of 
Celestia (including the one I am working on in Fedora).

Thanks in advance,
Tom Callaway
