Uses far less fuel mass for the same amount of thrust. Like the other poster said, an important component of a rocket engine is not only the amount of mass you can throw out of an engine but also the velocity at which that mass leaves the engine. In fact velocity is far more important (KE = 1/2m v SQUARED). So an ion engine uses tiny, tiny masses at amazingly high speeds. You don't get much kick out of one, but if you're not in a hurry and run it for weeks and months, then you'll get where you need to go eventually. What you do get is a massive savings in fuel, because the mass of fuel you're using per unit time is tiny. Also - GO KERBALS!
Well they could fire the thrusters gently while they drill but you'd need working thrusters for that. And of course the probe could just bounce off and back into orbit again if the thrusters misbehave. Ahh if only the harpoons had worked.
Come to think of it, quite a lot of systems have failed on this probe. The landing was a success but the mission doesn't look to be too successful.
The new political-speak means that the "reform" bill will make the NSA much worse and more oppressive than before. Enjoy your reform, suckers. Keep voting for those parties! It makes a difference - honest!
Not to mention that a) defibrillation alone without medication and oxygen has a very low success rate and b) not all cardiac dysrhythmias respond to defibrillation. And not all pulseless patients are having a heart attack. Try defibrillating a brain aneurysm or a pulmonary embolism and see what you get. Just like the defibrillators in airports - how many have been used successfully to date? This is good news only for companies that sell defibrillators.
"Linux works out of the box in the same way that MacOS or Windows does."
Bullshit. I tried installing the latest Ubuntu on my machine the other day and it doesn't seem to like my motherboard. At least I think it's my motherboard. Or my BIOS. Or something. Anyway you are clearly lying. Oh and if you do manage to get it installed, you are left to search for drivers and utilities and to edit conf files for even the most basic functions like say multi-monitor support whereas with windows this is maybe 3 mouse clicks away.
"Luekemia is not cancer of white blood cells, it's cancer of red blood cells. Lymphoma is cancer of white blood cells."
ROFL.
Look it up. There are 7 types of leukemia, only one of them has to do with the red blood cell line. Lymphoma is another kettle of fish altogether.
But that's great news because you don't want to outlive your money anyway. Anyway they mention the telomeres in white blood cells. Would be nice to see a corresponding increase in leukemia. As for 4.6 years of "biological aging" I take it they arrived at this number by extrapolating data from lab results - not necessarily true.
So you mean the rich get richer because since they own the capital, labor and production and there's less of it to go around, then people will pay more for it. And the poor get poorer because since there are plenty of poor offering exactly the same man hours, the cost of labor is relatively less? How is this different from the status quo? If I was in charge why the hell would I want to grow production at exactly the same rate (or more) than population growth? I want my things to be scarce. I think real economics might not work exactly the way you think it does, when government and special interests get involved in the market.
Public image or greed? I'm betting on greed. I mean it's "cheap" at $500 now, it was at over $1000 a few weeks ago. I'll go all in and I'll double my money again soon... any day now. Guys?

Yes it's called a ballot. You tick the box every few years and you get a lying, scumbag politician.
We'd better lock up the non terrorists then.
This is why you buy insurance. Rockets are tricky remember?
Wait till you see VASIMR...

Oh come on - you guys haven't worked out that Hitler was an alien yet? Mind = fucked.
I doubt the lander weighs 220 pounds, the comet's gravity is not all that strong... I agree it could have a mass of around 100kg though.
A good engineer would take advantage of this and include this feature as part of some experiments.

Could always ask North Korea for some. Oh wait, yeah, sanctions, my bad.
Because you were too busy watching Ghost Hunters?

I suspect torrenting of music to increase because of this. Can't force the market to pay for what it doesn't think it has to pay for.
Less is more. Artificial scarcity = artificially inflated prices.
Cos, you know, TOR is so anonymous...
You're thinking external combustion engines.
Not only "pilot error" but also very conveniently "blame the dead guy".
It's not outdated - the date is right on the article.
No industrial/scientific espionage at all.
