Canadian Arrow Taking Applications for Astronauts 149
Christian Nally writes "The Canadian Arrow X-Prize team is taking applications for its X Prize attempt. It's going to be a show down between this group and many others including John Carmack's Armadillo. Let's hope that the X-Prize foundations 'end of 2004' deadline doesn't inspire people to cut corners on safety."

However I just can't ignore the incredible amount of resources this 'fun' is going to cost. The amount of fules neccesary for one trip is just rediculous (don't give that clean fuel / hydrogen crap as it takes oil / elctrolysis to get the hydrogen in the first place).

If we're postulating mass space tourism, we can probably get away with postulating efficient solar or fusion power to go with it... they're both pipe-dreams hovering somewhere in the technological middle-distance. Then you can have your hydrogen by electrolysis without trouble.
To make space tourism economic, we need to either (a) make it possible to get into orbit using far less energy, or (b) make energy available much more cheaply. So nobody's going up there without some major breakthrough that would massively reduce the resources required.

That's only true of real mass-space tourism, something which is still some way off.
What's more likely,is the development of limited space tourism, for the very rich only... it has already started, and as the price drop a bit it will get more common.
Most likely, this will use traditional rocketry in a cheaper form, and it will polute a LOT. In particular, the upper atmosphere will suffer.
In short: if there is a way to make "cheap" space trips, space tourism will develop. Wherever it's polluting or not is sadly not the question.

If clean fuels were a priority, they would already be used in the exisiting mass transport systems. Thinking that a new power source will develope through space transportation is, as you say, postulating.

This is just wrong. People make a big deal about fuel costs, but that's really the smallest part of the cost of getting into space. If fuel was all that mattered, you'd be able to go to space for maybe a thousand dollars. As it stands, it costs millions. This is because NASA's launchers are fiendishly complicated, and require a tremendous staff of engineers to check, recheck, and replace tens of thousands of components.
Even the cost of the components themselves is dwarfed by the cost of paying 10,000 people for the 6 months that it takes to prep the shuttle for launch.
If we can do away with all this personnel by making the designs simpler, then we will have realized the dream of cheap spaceflight.
( and don't think it's not doable! Companies like Armadillo and XCOR may accomplish this! )

But it's still going to cost a lot. So there won't be millions of tourists a year, and most of those tourists will then not be able to afford a half-dozen vacations in Hawaii. I haven't calculated the relative fuel demands...
However, I doubt the energy demands will exceed that of one or two nuclear power plants. The income from such tourism should be able to pay for its own power...and remove more fissionable from the environment at the same time.

The fuel cost is very, very low actually; less than $10/lb of payload.
I worked out that if I was to go into space, I'd have to spend about as much fuel putting me there, as my car burns in a year. But unlike my car I ain't doing this every week or even every year. The number of people going into space for the forseeable future is only a few thousand; the number of cars out there are incredibly high, in the hundreds of millions, so the relative environmental impact of rocketry is quite, quite negligible.
And there are plenty of space technologies that have a positive environmental impact. Would the ozone layer hole have been found without satellites? I actually believe that overall, space will have a very significant net positive environmental impact.

As a matter of fact, the actual temperature at Low earth orbit is quite literally far beyond the melting point of any metal we have, Fortunately there is SO little matter that they can't actually melt anything. And in fact, the temperature is superheated by the fact that there is so much radiation, and so little place for that energy to go once it's in the few particles of gas that make up a soft vacume.
Cooling is indeed a problem, however, as the only method of cooling is to vent waste air or fluid, which becomes a potential threat to future low earth orbit satelites, as it retains all the potential energy, and the mass that doesn't boil into gas will freeze, because of the potential energy being ripped away by the effect of a near freezing temeperature boiling point (for water) in a near vacume. of course, venting also contributes a lot of kinetic energy into the droplets of ice, so they aren't easy to recapture...
This is why the moon is ideal for a permanent space presence, because there may be a LOT of ice at the poles, from comet and metoerite impacts, and the ice would serve both as a source of fresh water, and as cooling. habitats could be burried under the natural radiation shield of the moon's surface, although some research wouldn't be applicable, since it needs the microgravity of a low earth orbit to develop.

But Explorer 1 was not all that massive.
So the Canadian Arrow rocket is just going to end up re-creating Alan Shepard's flight, more or less. Rather just, I think, considering that he was launched by a Redstone missile.

Almost all modern liquid fuel engines use regenerative cooling (a technology developed by amateurs in the US, IRRC).
On the other hand, the V2s used pendular integrating gyroscopic acceleromiters (PIGAs) to shut off the fuel supply once the V2 hit a certain velocity. (One nice thing about PIGAs is you can put a counter on one of the bearings to irectly measure velocity instead of having to integrate acceleration yourself.) PIGAs are still used the US MX ICBMs. A couple of summers ago I worked on some replacement technology, but PIGAs are still the most accurate acceleromiters that can withstand the hundreds of Gs encountered on rentry. (They're also pretty resistant to EMP and radiation degredation from being stored long term near a sphere of plutonium.)

In fact, to achieve 100 Gs you would have to drive around the texas motor speedway corners at 1,056 miles per hour. Those are some mean turns, there. And remember just because the space shuttle can achieve a speed of 17,500 mph, doesn't mean it can make a 750 foot radius turn at that speed (which at 27,450 Gs would tear the shuttle to itty bits, and make puree out of the crew inside).
Just for comparison sake, the G forces of accelerating, in a Straight line, at the speed of light is a mere 267 Gs. However, traveling around the curve at the Texas motor speedway at the speed of light would generate 3,110,837.4 Gs.
Obviously, the tighter the curve you're making the higher the G forces.
Hope this helped, and BTW, I used the speed that light travels in this solar system, not the theoretical speed in a pure vacume.
