Thanks for the excellent additional information I hadn't seen any details on, but have been curious about. I believe development of space should begin with drones and robotics. A big part of what slows us down in developing space is our concern and focus on putting people into space. We can speed this up by taking people out of the equation during the initial development and production. We could build the infrastructure to make it EASIER to get people into space. I wrote about this a bit more a couple of days ago, but I didn't have these interesting details you added which are very complimentary to my brainstorming ideas. :) Resteem.
