I've been looking for hard-ish sci-fi space comics (space exploration, space colonization, human civilizations in other star systems, etc.) but after looking high and low, I'm not exactly impressed with what I've found. I've found a few things, but I need to broaden my search by drilling down into more mainstream (Marvel, DC, etc.) fare to find runs, if not titles, that fit the criteria.
Any suggestions? I'm looking more for art than writing. I want to see what good artists do with space ships, high-tech of the more realistic variety, etc.
Akira is a pretty good example of what I'm looking for, even though it only spent about 20 seconds in space; lots of great, gearhead-looking design and rendering. There's lots of near-future tech that looks pretty plausible, rather than the usual Kirby-esque hackery (I like Kirby, don't get me wrong, but realistic futuristic tech, it ain't). 2001 Nights would be perfect, if Otomo had drawn it.
It's a style thing, really. Gimenez' work on Metabarons is breathtaking, but the design aesthetic is further afield than I want to go.
Anyhoo I'm rambling so I'll just shut up now.
