STOP CALLING IT "SPACE EXPLORATION," PLEASE! Eight billion people want nothing to do with space exploration! They want SPACE DEVELOPMENT rather than an ever continuing "space exploration" that has opened nothing to developing space and energies for life in the space frontier in the last sixty years! NOTHING WHATSOEVER!
"Space exploration" has succeeding in one thing only! It has succeeded in keeping the space frontier closed to all of Mankind except a totalitarian state elite few dozens over sixty years.
Also, the Moon and Mars offer the eight billion nothing more than [limited-in-the-extreme-of-limited] cul-de-sacs!
Manmade in-space spin-gravity surface stations, colony-Arks, farms, dozens, hundreds, thousands, of other differentiated facilitations, the promise of massive numbers of ships and shipping trade lanes and cloud-city like multiple planet-orbiting living and working spaces, show the only promise of a future for thousands, millions, billions, trillions, and more, of Earth-life progressively developing SOONER RATHER THAN LATER!
Mankind in mass large has a mass genius for sensing closed systemic traps of tight cul-de-sacs like the (MF) mainframe computer-like Moon and Mars . . . versus the developmental potential of attainable local and wide area networks of open systemic (PC) personal computer-like in-space facilitations.
