It may look like the International Space Station, but it isn't. The space craft is Nautilus-X, an American concept for human exploration of the space frontier. The spacecraft was designed for six persons to explore space for two years. It contains a rotating torus to generate artificial gravity.
The visions described are in a figurative telescope looking two hundred years into the future. That future will retain much of the present. Thus, many visions are of preservation and enhancement. Other visions describe a frontier. That frontier can be a different way of designing the city. Think of urban places most supportive of human growth and potential. The frontier may be of knowledge, as with the growing torrent of planets discovered orbiting neighboring stars. A commonality is the potential - whether desired, needed or feared - to be part of our human existence two centuries in the future.
Tales of Futures Past provides some context to this endeavor, being a compendium of past visions of our present world.
Visions can move people to change the status quo. Such visions should be of a quality that excites the human soul. ‘Gloom and doom’, although sometimes useful in showing the need for change, will seldom move enough people to actually implement change.
People respond to visions that portray an attractive future for themselves and their children. To move many to action, such possibilities must be both optimistic and exciting. The envisioned future must be perceived to have value and be desirable.
