I propose a fortnight-long 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 !


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.

    $\begingroup$ @dot_Sp0t feel free to do so, but there's no requirement to. When the topic challenge is finished, I'll collect all the space-colonization questions asked while the challenge was going on, and answer the question with a link to them. $\endgroup$

  • $\begingroup$ @dot_Sp0T it won't be that difficult to simply click on the tag, go to the "sort by newest" tab, and collect everything from this date on upwards. $\endgroup$
