This would equate to losing 20 Hummer H3s worth of mass every second. Now, if only that would happen here on Earth we would have a lot less pricks on the road.

More education profiteering. Closed format, limit accessibility, isolated platform...

Humanity will never grow as a species until education is free and available to everyone. This is a road leading in the opposite direction.

Maybe they'll use the source code for Norton GoBack to rebuild the program into less of a headache.

It's not a matter of what it's made of, it's a matter of how much of each constituent is present.

Much of the matter on Mars and Earth are similar, however the proportions are different. We know that any rock that has been on Mars for any great length of time (relative to the solar system) will have a certain percentage of certain chemical compounds due to the entropy of the matter and atmosphere. The same can be said for Earth, Mercury or any other rocky body that we have data on.

The Moon is a special circumstance, as it shared the Earth's entropy for a very long time prior to the great impact that dislodged the matter that eventually coalesced into Earth's rings and subsequent Moon. Because the chemical makeup and percentage of chemical compounds of the Moon is similar to that of Earth prior to organic life, we can assume it's local origin.

You said " if we visit and asteroid and determine it has similar chemical make-up. Must we conclude the asteroid came from Earth as well?" - if this ever happened, we might assume it came from Earth. You've never heard of this because it's never happened. We've found hundreds of thousands of meteorites and asteroids that have the same basic compounds as Earth, but none that share a makeup consistent with that of Earth. This is because they came from the same pile of matter the the solar system formed from, but they're evolutionary chain progressed differently.

"Hey, can I check my Facebook real quick?"

"Scientists have confirmed chemically..." This seems to sum it up pretty well. The constituents of Mars differ from that of Earth, the Moon, or any other rocky entity that we scan, test or study. We know the Moon was once a part of Earth because it shares similar chemical makeup to that of Earth. That being said, the eons that have passed, and more precisely, the organic alterations that have taken place on Earth have modified the chemical makeup of Earth's crust enough to differentiate between a sample collected here or there. While it could be coincidence, you could equate this to finding a MacDonald's cup across the street from McDonald's. Could it have come from another McDonald's? Sure, but it probably came from the closest one, and it sure as hell didn't come from the Burger King down the street.

Oh good, now I can spend $400 on a textbook that I don't even get the pleasure of burning when I'm done with it.

I'd rather see cyber war between Palestine and Israel than real war. The can DDOS each other all day as long as it keeps them away from car bombs.

It seems that most malware originates from the Eastern European block, mainly Russia and the former USSR nations. I wonder if this is economically driven or socially driven. Is the creation of malware an attempt to generate revenue (via trojans that must be "purchased" to unlock all features and "remove infections"), or is it some type of political statement against the rest of the internet. If there was great revenue to be had, you'd think the malware would come from all over the world. Why the isolation to such a specific area?

The intellectual property lawsuits are getting out of hand. The constant litigation between Apple and [insert every other phone manufacturer] is not only holding back innovation, it's passing the costs on to the consumer. The amount of money these companies spend fighting over small print, legal wording, and patent technicalities is atrocious; in the end, we pay for their lawyers and court fees. Apple should be encouraging competition, not trying to crush it. Let the consumer decide if Motorola deserves to compete with Apple, not a court.

...but does it really matter that it was unmanned? There was no inherent risk for a regular pilot to monitor the same situation. I would hardly consider this a " tedious or risky intelligence gathering gig."
