I was lucky enough to beta test for Loki on Tribes 2 and the most frustrating thing was the release. No it wasn't that we had problems making the deadline and getting all the bugs worked out for release, it was that Loki wasn't allowed to release at the same time as EA. We were ready before the windows release. We had better performance and stability then the win guys.
I remember reading the listservs and hearing all the win guys bitching about frame rates and how they had to turn everything down while I was running everything maxed and had a comparatively old system.
So when the release day came, all of us linux testers where sitting there with our beta accounts laughing at the win guys bitching about performance. It was a shame to because they ended up taking a lot of cool features out in the name of performance but on the linux side we already had no problems. Seems to me we had to wait at least a month before Loki was able to ship out the linux copy, and all we did during that time was check the patches that kept us compatible with the windows version.
But getting it to the moon does NOT require us to leave earth's well completely, we only have to travel part of the way and then let the moon pull us down. This is less then the energy required to leave the Earth's gravity well and transfer to the Sun's well.
Plus by constructing on the moon we don't have to provide the same basic support frame. We use the moon, at a lagrange point we have to build much more.
Lowering the material back to earth doesn't take any energy on our side, getting it into the Earth's gravity well does. The Lagrange point may have equal pull from different solar bodies but you still are going to dip into at least one on the way out and over to the Earth. That's going to take considerable energy.
If the H3 doesn't outgas on the moon it is not going to magically outgas on the transport. In the short term, any losses due to outgassing durring handling is going to be minimul and easily offset by the cost of boosting processing equipment out of LEO.
That's where the massive equipment is, why push all that out ot the moon or out to a lagrange point? Use the least amount of fuel and put those in LEO. I never said LEO was outside of the well, if it was it would require energy to bring the material to the processing in LEO and that would negate one of the points of putting them there, the minimal effort to bring material to them. You just use the earth's own well for you instead of fighting it.
Wait, you say it's to much to work to put equipment onto the moon, then go on to say we should put even more equipment into solar/mercury orbit?
Why do we need to process anything out there? Scoop up your regolith and ship the whole damn package back to earth. Moon based "catapults" or mag lev systems would probably work fine, and let the Earth's grav pull them in.
Process it all on Earth, or even better, in LEO. That way we have fuel waiting in orbit for vehicles and they don't have to haul it up with them. They carry just enough fuel to get into LEO then stop by the nearest "gas station" and fill back up. HUGE energy savings right there. So we get our cheap(er) space fuel and Earth gets some nice new power supply.
It's even easier then the Apollo missions. All you have to do is throw it in a little container, something like a current cargo container that can go from ship to railway to truck, throw it off the moon via magnetic rail system and catch it in earth orbit for a nice ride down on a spacecraft.
OR design the system to reenter and land, parachutes are cheap and just strap some big ones on to keep it from hitting to hard and you don't even have to put the effort into going up for the material. This isn't exactly delicate stuff, no need to treat it carefully. If you're worried about landing it on land, parachute it into the ocean and then send a crew out to pick it up, either floating or land them in shallow water. It's probably way cheaper then building and operating a whole space system just to carry this stuff down.
Other options include making refineries in orbit to take the regolith and work on it there. Then send down stuff or, even better, use it for fuels in orbit. Now you don't even need to carry all your fuel into orbit with you, just enough to get up and then you top off. Much like the SR-71 use to do. Once you're up there the fuel consumption goes way down. It's just putting all that initial effort out that takes so much and ends up costing alot.
Arent the people who do this pretty much putting a big white and red target on themselves? I was under the impression, with things like the PATRIOT act, as well as the DMCA, that this type of thing would get you detained without a lawyer.
You've been watching to much drama TV (News). Even so, one thing that American's should be known for by now is that we don't always follow our own laws. If a law is unfair or unjust or generally disliked, we don't just talk about it, we do something about it. It started way back with a little tea party.
Now, with the help of the internet, information can get out before those in power can react. Slashdot is a great example of instant dissemination of information. Even if the server gets slashdotted at least the first few hundred people got the information and can then get mirrors out for everyone else. Even the fastest government agency is going to have trouble keeping up with the hundreds of bored geeks (slashdotters) with nothing better to do then play cat and mouse.
Yeah, I'm sure glad they had to tell me that. Wouldn't have been able to figure it out otherwise. So you think they'll get second unless someone else gets it?
"Blowing shit up" isn't an "issue" I would call it more of a "job perk". One of my goals is to blow up the test cell here before I graduate. Or at least put the test cell to good use and to prove the necessity of one.
Think explosions are fun? Check out Aero* Engineering.
*aeronautical and aerospace engineering are just explosions at different altitudes. Choose accordingly.
scramjets are completely different. They work on a principle of compressing the incoming air and then using a combustion chamber to blow it out the back at higher speeds. The big difference is that the air intake is compressed down slightly and that the combustion chamber has a constant combustion going on.
A pulsejet/detonation engine uses the previous detonation to compress the air/oxidizer for the next one. I've seen some designs with two outputs, it actually just oscillates between them. It's in a U shape and the detonation on one side send the shockwave to the otherside to compress that detonation.
Here's a good site with pics and even audio of pulsejet engines. http://home3.inet.tele.dk/kennethm/ There's also a section on ramjets which are just variants of scramjets for slower speeds.
This PDF has the osciliatory pulsejet design with pics starting on about page 5 or 6. The link is from the Valveless Pulsejet Engine article linked under pulsejets in the above site.
Actually the Japanese probe was launched over a year ago (can't remember the exact launch date) and suffered a engine failure. They did some orbit changes and had it swing by Earth agian before heading to Mars a second time. This time how ever it's on a free trajectory and shouldn't need much engine use. They are running extremely low on fuel though and some of the parts have begun to fail. They're not completely sure the probe will make it. But it does result in a swarm of probes heading towards Mars and hopefully will result in alot of data coming back from various parts of the planet and from orbit all at the same time which will give scientist a better overal view of the planet.
there isn't alot of air at that altitude compaired to sea level.
3.21e-5 slugs/ft^3 (.01786 kg/m^3) at 100k ft (~30km) compaired to.002377 slug/ft^3 (1.225 kg/m^3) at sea level
I would think a droug chute would be used until they get to denser air. I would be worried about tangles on their control lines and static lines.
If the RIAA had to refile it would cast a doubt on all the other filings they've already put through and cast a doubt on the legallity of bypassing the need for a warrent to collect this data. Not that this is a bad thing.:)
I think these guys have been talking with their lawyers and faculty and have had this planned for a while. I use to work as a student assistant at my university's ResNet and we took all this P2P stuff very seriously and asked "what if?" alot on new developments like this.

I'm tempted to pick up my general licence now. Just got to go learn the CW. Then we can have a fun /. CW DX contest.
We just strung a 10m line up at the lab, might as well use it.
what could they do though, even if warned? Basically just clear their schedule and get a fire extinguisher.

Actually it would mean you're paying more per song then we are.
.99USD, About 24% more.
0.99 EUR = 1.225 USD
So you guys are paying slighlty more then our
brings a whole new meaning to muscle memory.

1.) You can get insurance for anything, the Premiums may be a little high though.
2.) They aren't going into orbit so there is no way to get stuck. It's a simple projectile trajectory, up and down like a cannon ball.
3.) That's the point of the X-Prize.
4.) We can only hope!

except that they've only fallen 2000ft, any guesses as to if the test vehicle made it to terminal velocity?
