The Apollo 13 malfunction was caused by an explosion and rupture of oxygen tank no. 2 in the service module. The explosion ruptured a line or damaged a valve in the no. 1 oxygen tank, causing it to lose oxygen rapidly. The service module bay no.4 cover was blown off. All oxygen stores were lost within about 3 hours, along with loss of water, electrical power, and use of the propulsion system.Apollo 13 accident
I am pretty sure That I don't have all the failures listed here, there were 3 as I recall
The astronaughts afterwards said something along the lines of "If they had given this scenario to us in training, we would have walked off the program right then and there." This was mainly because NASA had been giving them all sorts of implausible scenarios where something goes wrong, and they thought that none of them could ever happen. Most of them were also 2 component failures and not 3.
It's not going to be something old that kills us, it's going to be something new that we never thought of.
They aren't ellected, it is a voluntire group in the neighborehood that is establised when the neighborehood is created. Plus, after 20 years, the enitre neighboorehood votes to see if we still want to keep the Home Owners Association. At leat that is how it is in Northern Virginia.
Cooling would be a problem. Those very large smokestacks you see producing a white cloud (steam, i believe), have to be somewhere. And at some point you have to have something above the ground, but you do have a point for burrying the reactor itself. Maybe put it in a smaller version of Cheyenne Mountain
Actually, on a side note, if a terrorist tried to crash a fully loaded 747 (the big ones) into a Nuclear Power plant, what would he hit? He could hit one of the smokestacks, but that wouldn't do much as they others should be able to take up the cooling load.
Or,better yet, does anybod that is not a nuclear engineer even know where the reactor actually is in a Nuclear Power plant?
If they think a Nuclear Reactor could take a plane hit, I am confident they designed it to take much more than that (safety margins are usually designed so things this big can take twice the stress they claim Example:Elevator rated for 1000lb should be able to take at leat 2000lb, sensors just prevent you from using it at over 1000lb).
Besides, I don't think anyone (in the US) will let a terrorist take over a plane anymore unless everyone on the plane is dead, crippled, dying or a child.
Actually, most people running nuclear reactors ARE ex-Navy personel. After they serve there years in the Navy, they are EXTREMELY employable at the power plants due to their level of training and experience. And these guys probably get at least $100k per year at a reactor plant, more that double what they get in the Navy when they retire.
It's not so much delta-v that would be a problem, as much as the reaction mass that would be the problem. m1*v1=m2*v2. The asteroid must weigh several thousand metreic tons at least. The amount of reaction mass necessary to change a 1 metric ton mass by 1 meter/second is 3.33 miligrams, assuming we shot those miligrams off at the speed of light. We are talking thousands of tons of asteroid and a much less efficient engine. Until we get nuclear rockets and a space elevator up, it probably wouldn't be economical. Unless we could use its (ralatively) close aproach to mars in 2015 to swing it around to the earth.
Interesting idea, but we have no idea of what the consequences are of rearranging the momenta of the solar system, or any other "environmental" impacts. How would you make such a decision without adequate knowledge of the impacts?
If moving one tiny asteroid would bring any harm whatsoever, then the solarsystem would have been destroyed long ago. Shoemaker levy 9, the meteors that have hit the earth (think of all those craters), the moon, mars. Saying that moving this thing would upset the balance of the solarsystem would be like saying spraying a sing dandelion is going to cease oxygen production on this planet entirely.
We're working with Visa, which will move from magnetic stripes to contact smart cards and eventually to contactless smart cards (they'll be scanned from a distance, vs. cards that have to be swiped).
So now credit card theives don't even have to steal my wallet or look at my card, they can just get the information by brodcasting the query signal? How is this a step forward for security IN ANY WAY? Even if it requires a specific code to transmit, every retailer would have to have the code, so theives could certainly get at it.
Some friends of mine stopped in at the Mac store the other day, and saw a Gual G5 with a Gig of Ram and 23" Widescreen monitor with Unreal 2004. They nearly cummed their pants it was so good.
Ok, is that 17,500 tons ship tons or, 2000 lb tons or metric tons. All three are differect measurements so be carefull.
30+ knots is the unclassified maximum speed. In reality it is probably closer to 50. If the cold war were still on, I'd say ask the Russians (who would know better than us in some cases).
But manned space flight is incredibly expensive in comparison
That is because we use Chemical rockets. If we use nuclear rockets as posted in a previous slashdot story Nuclear Space.com we can do it for less. And we have made a nuclear reactor that can survive blowing up on a launch pad, and one that did it too. So we don't have to worry about radiation fall out. Besides, there is only so much a robot can do. And, we can get resources from space to earth. Want 100 billion tons of nickle or Iron anyone?
And just think about when (NOT IF) we get a space elevator up, the cost of getting to orbit will plunge.
Actually, in FY 2004 (the one that is ending soon), the Military got 380 billion (source:whitehouse.gov).
Expanded to 415 i think due to Iraq. (Can anyone be more precise?)
This is less than the social programs we have. Social Security is 513 billion and Medicar/Medicade (Department of Health and Human Services) is 471 billion. (Anyone want a $1 Trillion surpluss? Cut these. [Says the 22 year old US citizen]). The treasury got 392 billion
Out of a total 2448 billion, that comes to 16.9% (the 415 figure, not the 380) to the Military who employ many, many people. As oppsed to welfare, which gives people money for doing nothing. (Main reason I am opposed to that is a] forced charity, and b] I know of some drug dealers on it, that use it as a cover and I can't do anything about it)
Besides, i think the Military would help NASA if they were allowed. Both for the technology, the improved rockets and the ability to have more access to Satelites. The first NASA satelite went up (successfully, as opposed to a ball of flame) on a Military rocket, from what I understand. Actually, Increase NASA's funding to 50 billion a year, get some retired Generals in on it (and let the Military help as well), and see what happens and how fast the results roll in.
Give me 20 years and a Large enough budget, and I will make the Moon self sustaining. For Mars, give me 30. And that is before terraforming, without any supply train from earth after 20 years for the Moon and 30 for Mars. After that everthing I need will either be there, or I can get it from Space.
Basically, water is the only thing I would need from space. Everything else I could make locally at that point.
Lets get off of Earth first, then worry about colonizing other Systems. Besides, we still need to find inhabitable planets first (by inhabitable, i meen as in as inhabitable as the Moon and Mars as opposed to Venus, Mercury and Jupiter). The moon we can live on/in. Mars we can terraform. We can live on other moons in this system.
2) Purchase a UK power adapter from a UK Apple dealer before you go. The day before you leave the US for home, ship all the manuals and paperwork back to the UK, along with the US power adapter. Take nothing but the laptop and a UK power adapter in your bag through customs.
I don't know about Apple Laptops, but most laptops that I have seen don't need a power adapter anymore. They all support 50-60hz and ~100 to 240V. So all anyone would need would be a plug adapter.
Actually, if he goes to a Dell repair shop (or whoever made the laptop in the UK) he should be able to have them install a UK keyboard at a nominal fee.
Try Best Buy or CompUSA. And don't get a Dell, get a Toshiba. They do have support in the UK. And their power supplies will work in Europe with only a plug converter. (I think the UK doesn't have the same 2 plugs we do).
This is the reason why I keep directing people to use Mozilla and Firefox instead of IE or OE (Outlook Express*). I set my parents up with Netscape when it was good (ie, before AOL bought them) and with Mozilla more recently for an update. The people I give this too never go back to IE or Netscape 6/7. Mozilla is gaining.
I have heard this is a Canadian law and this would be a drastic improvement for teh USA as well.
If a lawsuit is deemed frivilous by the Judge and thrown out of court, the Lawyer has to pay the cost of running the court house for that day out of his own pocket.

1. A false publication, as in writing, print, signs, or pictures, that damages a person's reputation.

2. A false and malicious statement or report about someone.
At one point in high school, I was installing Windows 95 on a Mac for my Computer Teacher. (Read on for how, no flames about it not being possible please). We had a PCI card with it's own Intel processor and ram on it. Using apple+enter would switch to the second processor. Both would run simultaneously. A similar setup should be possible for a purely Intel/AMD machine and produce better performance.
Do my eyes decieve me or do I see a 3-Pin FAN connector (just below chip that reads:'SSC-10050') on the mother board. right next to wha apears to be an RCA jack.

Actually, I've heard that windows says the same thing, only for a Nuclear Submaring.

A) not sure a space station could be moved intact from earth to orbit. Would probably have to be moved in pieces.
B) HEAVY LIFTER RIGHT HERE Liberty Ship How is a 1000 Ton payload for ya? And yes, that is the correct figure.
