British Man Trades Frequent Flyer Miles for Space Shot
lvmoon writes "Start saving up your airline miles. Alan Watts, a British businessman, was able to use his 2,000,000 frequent flyer miles for a space flight, a ticket aboard a 2009 Virgin Galactic space flight." From the article: "Electrician Alan Watts said he flew to and from the United States on Virgin Atlantic flights more than 40 times in the past six years, earning him enough miles to take the trip into space with Virgin's space wing, London's The Sun newspaper reported Friday. The trip cost 2 million frequent flier miles, compared to the 90,000 miles required for a first-class flight from London to New York." Besides being funny, does this say anything about space travel in the 21st century? Is space is no longer the final frontier? I'm pretty sure Roddenberry didn't have frequent flier miles in mind when he came up with the Enterprise.
He's lucky too because he's got this free ticket in before the much expected hyperinflation in the air-miles currency.
This surprises some people but in fact, air-miles are a form of currency. They can be exchanged for real world goods and services and therefore have an intrinsic real world value. The problem is that the vast majority of air-miles go unspent. Since a constantly increasing amount of currency is chasing a limited amount of goods the value of the currency is constantly falling.
The fact that this guy was able to accrue two million air-miles doing a normal job tells you that inflation has already crippled the currency. I soon expect air-miles to be practically worthless.

Space travel is a temporary situation. It will cost too much and become unfeasible in the next 50 - 100 years.
You have that back to front. The current difficulty of doing space travel is temporary, because it is the result of poor strength of materials and poor energy usage.
Materials technology is improving at an extraordinary pace, and there is now a whole industry dedicated to manufacturing nanotubes of one form or another, despite this being only the beginning of work on nanoscale materials. Much greater things are on the way. And with stronger, lighter materials you can build much better space-worthy craft, not only hugely safer in the hostile medium but also able to withstand greater dynamic forces more safely. And more cheaply!
Then we come to energy. Contrary to the daily propaganda of environmentalists, there is no shortage of energy on the planet --- the surface of the Earth receives about 150 thousand times more energy from the sun than mankind is forecast to need by the year 2020. Our "energy problems" simply reflect our poor ability to harness that near-zero-cost energy, currently.
But that can change, especially in the context of space flight.
For a start, we can rise up through the bulk of the atmosphere almost without any energy cost at all, and many outfits are already experimenting with that, to the very edge of space.
And secondly, once up there, solar energy is freely available, and as long as there is still residual atmosphere around you, this gives you matter which you can use for propulsion, slowly building up speed as you skip through the upper layers. A relatively small amount of extra reaction mass is needed to boost the orbit out the final few dozen miles once you have close to orbital speed.
In due course then, on materials and energy grounds there is every reason to forecast a very bright and buoyant future for space travel. NASA-type costs are not required, as long as you're not in a hurry.
