About a year ago, I started writing an essay comparing and contrasting Bezos’s versus Musk’s visions for humanity in space. As is often the case, it expanded into a history of space visions in general, and how we’re finally returning to the old ones, after the tragic detour of Apollo. It’s out in the current issue, but unfortunately, isn’t yet available on line. I expect it will be in a few weeks or less, though.

This is sort of a space issue. There is a piece by Bob Zubrin laying out his concept for Moon Direct, bypassing what he calls the space toll booth (Gateway), and another by Micah Meadowcroft on how Mars will disappoint.
