Yes, we read too much A C Clarke.....but I'm not going to regret it!

But we must indeed think about those issues , as you expertly point out.

Some thoughts:

Space tourism with ballistic flights above 100 km is a reachable goal.

What would be the next one?

Tourists in low Earth orbit....?

Why not this: what would people want from going to space?

Number one: the VIEW !!!!!!!!!!!! Then, weightlessness....

How?

How about a capsule (yes, no wings, no landing gears, but parachutes) with no docking hatch but a bulbous front window (enough for 2 together); that way, no spacewalk needed as the view would be as good, no spacesuit needed either; no space station to dock to as the trip would not last long enough to justify it, no need to exercize either (too short a trip). The capsule would face downwards and allow for Earth contemplation.
Two more things: the trip should last just long enough to give the participants to fly at least once above every part of the world, in daylight. Every part, means, yes....a POLAR ORBIT and a low one!!
That would enable flying through northern and southern lights, and see the whole World! It would also allow for night sightings (if it's not sun-synchronous). The lower the orbit, the more details on the ground and the faster it looks.
No need for a permanently manned near equatorial space station, but an independant capsule in Polar earh orbit with a special window!!
