Presume this is a railgun or a mass driver for flinging spacecraft into orbit. Bet it would be awfully cold on your bottom sitting on luna’s rock and dust like these folks are doing. They probably live underground to escape Sol’s radiation. Still, it would be fun to go. It is, actually, in the imagination.

I like the little red wagon.
Dad and son are just out to watch the spaceships take off.
The red wagon is a nice touch. Perfect for collecting moon rocks. Not sure what else you could do on the surface, actually, (other than astronomy and spacecraft construction and servicing) though Poul A.’s “Fleet of Stars” describes a Luna sculptress doing a huge statue of a running woman.
