Yes, it's interesting to note how many recurring themes there are in Jarvis's lyrics, such as space, as you mention.

The other day I happened upon this image of The Leadmill and it reminded me of how many of Jarvis's songs (especially young Jarvis's) mention the sky, the moon, the stars, the night, nocturnal walks, etc, and you can just imagine him wandering the dark, empty streets of Sheffield in the early hours of the morning after a night out at The Leadmill. 

Roofs, roof-tiles and especially curtains crop up a lot, too. I find this quite funny and it makes me nostalgic, as well, since curtains seem to be dying a death these days, if modern estate agent pictures are anything to go by. Curtains have associations with night-time, too, of course, particularly in the winter, and also of the curtain-twitching suburbs which Jarvis is so fond of writing about.
