These are FarGetaNik's textures from Project Echoes (I'd prefer less "messy" oceans on the Earth texture, but it's much better than what's currently here). I've checked the texture licenses more carefully this time...
The Mercury normal map is based on the USGS DEM, but also uses data from another texture with no license info; however it's virtually indistinguishable from my attempt to make a normal map from just the USGS map (the only difference is that FGN's map has the correct scale at the poles), so it shouldn't be a problem.
Project Echoes' Venus cloud texture is ultimately based on images licensed CC BY-NC-ND, so it can't be used. I've instead used this texture also by FGN, which is a modified version of Björn Jónsson's Venus cloud texture currently included with Celestia.
The Venus surface and Earth night textures are based on textures by John van Vliet without a clear license, but he usually licenses his work as CC BY-SA, so these should be fine.
The Moon surface texture is based on a texture posted on Celestial Matters; the thread isn't saved in the Wayback Machine so it's impossible to find license info. The texture was probably intended to be used in Celestia.Sci, in which case it would have to be compatible with Celestia's license. Edit: The thread actually is saved in the Wayback Machine, but there's no license info.
All other textures are definitely compatible with Celestia's license.
The models+textures for Phobos and Deimos are unchanged because they've already been updated by @Askaniy. Closes #10.
