I don't think it would have much of an effect on us as an evolving species, despite that lovely scene in 2001:ASO with Moon Watcher. But I do think it would have an effect on us as a cultural species. I am currently witting a short story where this is the case, and man decides to take a specially made air craft, with a primitive air scoop, and pierce the 'up'. he has some latest technology, supplementary oxygen, a heater and an artificial horizon. I hope to finish it.
