station lost

[argentpanther]

this weekend I was playing around with the demo version. I had a thriving station and got distracted and inadvertently hit the menu button and got popped back out to the solar system/earth orbit view. I could never figure out how to return to the interior of my station and I had to start over with a new build. I noticed after that when i exited the second station interior that the colony count on the game stats had gone up to 2. which suggests to me the system new there were 2 colonies in LEO.
so, is the fact that I can't return to the interior of my colony once I leave an artifact of the demo mode not having save capability?
or is there some other UI feature that I haven't found that would let me return to the interior of my previous colony?

thanks
