The return of the last Space Shuttle has reminded me of an article I wrote in 2000 for the online magazine 
Jackhammer E-zine. Eleven years ago — pre-9/11 — the future looked a little different.
How         To Make a Spacious Fortune
"Space is big.         Really big. You just won't believe how vastly, hugely,         mind-bogglingly big it is."
If space is as big as         Douglas Adams says (in The Hitch-Hiker's         Guide to the Galaxy), surely there's ample         opportunity for making money from it. Unfortunately, big         though it is, space consists mostly of one thing: nothing         at all.
But perhaps this very         lack of something is what the daring entrepreneur can         capitalize on. Wouldn't people pay for the privilege of         being among the very first to contemplate such vastness? 
What we're talking about         is one of the biggest money-spinners on Earth. Whole         countries depend on it for their survival in today's         competitive, commercial world. It's tourism.
What works here on Earth         could also work in space: luxury hotels in orbit around         the globe, giving their lucky guests the chance to sample         the novelties of astronautic life. Who would pass up the         chance to try out a zero-gravity toilet? Who would throw         over the opportunity of experiencing that curious multi-dimensional         disorientation that leads to space-sickness?
It's possible, of course,         to simulate gravity in space. But a slowly rotating         wheel, large enough for its centrifugal force to equal         even a sixth of Earth's gravity -- like the one in the         film 2001: A Space Odyssey -- is too big to be a realistic         proposition just yet, despite next year being when it was         predicted to be feasible.
Then there's the view:         the Earth, spinning in isolation, vulnerable in the void,         has been described by some astronauts in quasi-religious         terms. "My view of our planet was a glimpse of         divinity," wrote Edgar Mitchell of Apollo 14.
After being on vacation         for some time, it's natural to have the odd tinge of         fondness for the place one has so eagerly left. How much         more profound to see it hovering below, in the knowledge         that it's farther away from you than ever?
Having established that         there's a likely market for space tourism, provided the         price is right, it's time to look at the practicalities.         Let's assume that the goal is an orbiting hotel, and some         kind of regular transit service to ferry the guests to         and from such a desirable venue.
The first problem is         building the place, and for this it seems sensible to         take a cue from that other ongoing orbital project, the International Space Station. The ISS is likely to cost         American tax-payers $25 billion, not counting the         contributions from the ISS partners in Russia, Japan,         Europe, Canada and Brazil. The occupants of the initial         few modules, enjoying reasonable life-support and         accommodation for a crew of three, remain in orbit for         about 90 days, but our tourists will probably want to         stay a much shorter time.
Although building an         orbital hotel will be a massive technological and         financial undertaking, the knowledge gained from the ISS         will point the way. The main reason that a hotel is not         being assembled far above our heads today, is that to be         viable a hotel must be easily accessible. A reliable and         frequent transport system is needed. NASA's Space Shuttle is at present the only (partly)         reusable transport available, but it has proved itself a         flexible and adaptable vehicle.
Each Shuttle flight costs         in the order of $300 million, so with a payload of         perhaps six guests and one or two service personnel, the         cost could be in the region of $50 million per guest at         today's prices, for the transport alone. This is         astronomic, even for the most exclusive accommodation on         -- or off -- the globe. 
The Shuttle's very         versatility makes it non-cost-effective for the         comparatively simple task of getting people into orbit         and fetching them down again. A more specialized vehicle         is obviously what's required, perhaps one with greater         capacity. There are many vehicle designs on the drawing board, several of         which could serve our purpose. (For sub-orbital flights         only, there is even a self-build kit version, the SpaceCub -- a snip at half a million         dollars, plus fuel.)
On arrival, what         entertainment would be available for these exclusive         guests? Naturally a fully equipped fitness room would be         a priority. Even during short periods of microgravity,         the human skeleton loses a significant amount of calcium         -- a process called demineralization -- due to lack of         muscle-stress on the bones, so a daily workout would be         an essential part of each guest's routine.
There would also be         periods of training. Life in space involves many hazards,         and though the residents would receive instruction before         traveling to orbit, there would be no substitute for         learning to cope in the environment itself. This hotel         would be far away from the usual facilities found in most         large cities on Earth; the residents would need to know         what to do in any eventuality. It's unlikely that the         rear of the bedroom door would be large enough to contain         all the emergency instructions. 
Apart from that, they can         simply admire the view.
There is a downside.         Prospective guests will be aware that this would be a         high-risk vacation -- one for which they are unlikely to         get adequate insurance cover. Holidaying in orbit, at         least at the start of the enterprise, would be for those         prepared to accept that they might never come home. And         such a vacation would only be for those who could afford         it.
David Ashford, director         of Bristol Spaceplanes in the United Kingdom, in his         paper, "Space Tourism -- How Soon         Will it Happen?" has estimated that at a ticket-price         of $10,000, "...probably more than one million fare-paying         passengers would visit space each year as tourists,         requiring a fleet of more than 50 spaceplanes."
There's money to be made         here. Get in on the ground floor, and you'll go to the         stars -- or at least take the first major step on the way.
