Here's what I put together last night. Not much so far, but you can see by the base, those are the four cylindrical living modules I plan to mount radially around the outer wall of the top level. Somewhat modest, but this is just the Mk1. I've discovered from weighing what's built so far that it all weighs much less than I assumed it would. I've found a $34 latex weather balloon (incl. shipping) 8 foot diameter on eBay that will lift 7lbs and the skystation as-is doesn't quite reach 1lb. This means future skystations may be considerably larger and better equipped. For now, I'm content to build this small "outpost in the sky" to test the idea for feasibility, before committing to anything grander in scope.
