This is one of my biggest circles (excluding the generic 'Following' or 'Pages' circles) and contains both people and pages to do with Space.

There are astronauts, planets, space agencies, space ships and space stations in here, among other things. If you're interested in space, take a look at this circle.

cc: +Earth - I think there might be some in here you might not have in your regularly shared circle. Please feel free to take a look and add whatever you like to your circle.
