Derek marvels at the display of the base. The miniature buildings on the moon have all been made to the exact specifications. It even shows little people going back and forth between them, carrying out routine maintenance and other functions. He is most interested in the spaceport. This is where human exploration and colonization would expand to Saturn and beyond. Then there is the Le Poitre telescope that scans for habitable new worlds in the galaxy. He could have spent the whole day absorbed in that base, but there was so much more to see at the exhibition.

He looks up to see which moon he will look at next. The woman with the tattoo that had been on the train is standing there looking at him, but disappears into a crowd passing by.

Derek thinks little of it. Due to medical advances, there are very few people in wheelchairs. Even less on the moon. The odd time, Derek would find himself followed by someone enamored by his chair. Life is too short for him to worry about it.

He powers his chair over to the volcanic moon lo and watches intently as lava oozes over the surface. The realism is beyond his expectations.
