I ran into an interesting glitch in the Galmap the other day.
I'm currently out in the boonies with mostly undiscovered systems around me, but I noticed that the Galmap was offering to sell me the exploration data for a nearby system or two. Hmm. I figured that they must be discovered systems, then, so I bopped over to one to see (without buying the data).
It was an undiscovered system. How strange. I went back to my carrier but the Galmap no longer offered to sell me the data. I wondered what would have happened if I had bought the data.
Today, again, I noticed that I could buy the exploration data for a different nearby system, and this time I bought the data. The sale succeeded, and I was then able to view the system map. But in this case, the system actually was fully discovered by someone else.
It's a bit of a head scratcher. I guess it kinda makes sense if the system is already discovered, but the first one was not. I still don't know what would have happened there if I bought the data.
Anyway, today as I was scanning a new system, Elite Observatory popped up a message about a small icy moon, saying "Close Ring Proximity." I decided to go check it out, and sure enough the moon was very close to the rings of the gas giant it was orbiting.
Of course I had to see what it looked like from the surface. The moon had many geysers on it, which only added to the amazing view!
There were a couple of planets in the system that had biologicals on them, nothing special, but I went over and scanned the stuff. The Fonticula were particularly easy to find on this planet

It had a methane atmosphere and everything was tinted a sickly yellow. I was grateful for my internal air supply
