Well, the new textures for Orbiter 2009 should more than take care of that.
Or are you suggesting a bluer Earth texture, as seen in the movie? I think it'd be a let-down after the Orbiter 2009 textures, but...I think someone has already done this (for Celestia?). So it may be possible to add for not too much work.
Oh damn, I missed the reply.
Actually I meant that the bases look a bit empty, with the moon bases having a very high level of detail, and the bases on Earth being mostly empty runways. More buildings and maybe some more vehicles for Earth would be nice.
