I propose a fortnight-long space-colonization topic challenge, which will begin today, August 10th, and finish on August 24th.
Most sci-fi stories feature humans in space. However, manned missions are currently in decline in the real world. Machines can often perform the same functions humans can, at a fraction of the cost. The various motivations for human space travel and colonization frequently put forward in science fiction are a fascinating topic.
I'm excited to see what kinds of questions this community can put forward in regards to space-colonization!
The topic challenge is now complete. Thank-you to all participants, and congratulations to Ash, whose question managed to get all three gold topic challenge badges.
