But that's all irrelevant to the article. Proper gravity for comfortable space travel is not the issue here; the issue is minimizing the cost of the travel. And sleeping astronauts travel a lot cheaper than woken ones. Plus, they don't need gravity. Unless someone is under the impression that proper gravity will help with the muscles of sleeping astronauts, which I highly doubt.
