"...is going to get the title Best Darwin Award Ever."
I hate the so-called "Darwin Awards" for their "HA-HA I'm *so* much smarter than these (often drunken) fools HA-HA"-attitude even though I generally like nasty humor, but I despise the attitude displayed in the above post even more. If the Wright who flew the first plane would have crashed and died, and you would have been there, would you have gloated "It's a good thing that imbecile cleansed himself from the gene pool"? I don't know how well this person has planned his rocket trip or even if he's sane, but I applaud him at attempting something I wouldn't have the guts to do.
Currently (about two nanoseconds after the story was posted) the above post has 3 +funnies, I hope that it goes down to -1 troll. But it probably won't, since joking about risky attempts that push the limits of human experience in the vein "HA-HA this idiot is gonna die HA-HA" is very, very popular on Slashdot.:-(

"Mr Bennett...wants to win the $10m...X-Prize. This award...will go to the first non-governmental outfit to put people on a rocket...62 miles...above the Earth...flying twice within a two-week period...[and]...also carry passengers."
In other news:
"A group of loosely organized computer enthusiasts from the website Slashdot have developed a space vehicle called the "Leech".
This craft is essentially a septic tank with enormous velcro straps. They have apparently bribed a NASA engineer with a $1m payday if he lets them piggyback on the space shuttle.
A model rocket engine has been attached to the rear of he septic tank because hey, rules are rules.

Brian Walker is an American who has had a lifelong dream of going into space. He's been working for a long time now to get there on his own. His website is here. His story is very interesting considering what all he's gone through to get this far. His launch date is set for May of 2002.

Yes, this group is called MARS - Middlesex Advanced Rocketry Society, of which I am one of the Flight Crew.
Bennet is basically a big joke in the UK, he has got all rocketry groups banned from using military bases to test rockets from, and one of his earlier rocket escapades burned a substantial part of moorland in Dartmoor.
Bennets rocket is nothing more than a scaled-up HPR (High Power Rocket) vehicle, and is nothing more exciting than is flown by many HPR enthusiasts here in the UK and the US.
Our most recent success flew last weekend - it's a true and proper amateur rocket utilising our new Hybrid rocket motor, quite possibly the most powerfull amateur hybrid motor flown anywhere in the world:)

The BBC and CNN do it again. They oversimplify matters so that they sound like better news than they actually are, in order to satisfy their increasing market of people whose IQ is slightly lower than their shoes size. At least this article didn't twist the facts like the BBC has beeng doing during the last few months (I still can't figure out why, and the whistle has been blown broadly).
I'm pretty sure this guy is running low on cash so he hurried up this test in order to get some media attention that would help him get some more funds. It doesn't really matter really, since I already know who's goign to win. That will be Armadillo Aerospace
They had a crash a few months ago and have recovered very well. their plans are the opposite from what most of the other contestant's are doing. They're working on a design that revolves around the ability to seat people on it, instead of trying to get higher than anyone and then picking up the parts. Actually, now that I think of it, I don't even think they're doing this for the prize, which makes them even better candidates.
Of course, now I am also oversimplifying things, but at least I don't make money doing it, so I encourage you to go to John Carmak's site and check out the logs. Maybe someone here can help out with those Windows ME features he's been having problems with (check out the last few log entries)

There are two kinds of people in the world: Those with good memory.
NASA aren't in business. Atleast they aren't supposed to be. But not even billionaires seem to be able to get into the launch business due to NASA. Check out what Mr. Beal said when he left the launch platform business. But the competition from the Russians and other players is immense (they can launch for 1/4 the price of NASA), and NASA shows no sign of being able to compete, and are falling behind the price curve at a tremendous rate.
NASA's proportion of the space pie is shrinking- commercial operators, some of them NASA contractors are growing, and NASA can't grow due to it's fixed budget from the government- it's actually part of the government. That's a good thing in fact. Companies are supposed to grow, Governments can only grow by increasing taxation.
NASA should stick to what it's good at, exploration, not commercial launching.
It's one thing to launch an 11m rocket some 5000ft, it's quite another to build a functioning spacecraft!
At the very minimum it would have to carry a ton of payload; most probably quite a bit more. To get an idea of the kinds of equipment involved, this link [af.mil] on the Delta II provides a good overview of the kind of sheer power and equipment needed to put even a relatively small 5 ton payload into space.
It turns out that it's a lot easier than you think to build an X-Prize-winning rocket.
The Delta rockets and other commercial launch vehicles need to get an object into _orbit_. This takes about 30 MJ/kg (the binding energy for LEO), or about 8 km/sec delta-V.
Satisfying the X prize only requires sending a payload up to 100 km. It doesn't have to stay there. This only takes about 1 MJ/kg (1.0e5 metres times about 10 m/sec^2). This corresponds to a delta-V of about 1.4 km/sec. This is much, much easier to achieve.
The reason why this is *much* easier (or more accurately, why anything higher than 2-3 km/sec is *really* hard), is that when the delta-V of your rocket is larger than your exhaust velocity, the amount of fuel needed to give that delta-V to a fixed amount of payload starts growing exponentially (it's roughly linear below this threshold). Typical specific impulses for rocket fuels are in the 2000-3000 N*s/kg range, corresponding to exhaust velocities of 2-3 km/sec. So, anything below about 2 km/sec can be accomplished with relative ease, while anything above about 4 km/sec requires a rocket that's mostly fuel (and probably multi-stage, unless you have extremely strong and light materials).
In summary, building a rocket that can lift a payload into a sub-orbital trajectory that tops out at 100 km is certainly within reach of a small group's resources.
[The real problem will be finding someone willing to pay for it. You can't lift payloads into orbit with this rocket, and cost of developing the rocket will probably be more than you'd get from the X-Prize.]
