It's only a matter of time...

:O :O :O

And people are telling me there is not a single microbe/ bacteria/ worm under that beatiful rocky Martian soil?

Bullshit. We did not dig deep enough yet.

It's kind of funny you say that. A handful of months after that statement, some moronic Congressmen banned NASA and some other US science entities from collaborating with China. I think the ban might have expired after a year, though. I'm not sure.

really is a shame that there isn't something else there to take a video of Curiosity as it starts to drive off.

Why haven't they invented a little rechargeable hover cam yet that flies around to gather video and topograhy data and can record the rover as it goes about it's business.

Amazing.

Looks a lot like a very dry area here on Earth.[/QUOTE]

Where did you get that picture from btw? I use [URL="http://mars.jpl.nasa.gov/msl/multimedia/raw/"]this link[/URL] but many of those pics are only available as thumbnails.

An outboard camera would have been a good idea from a PR perspective. They're getting better at planning these things for public interest impact, but not to the point of compromising the science work they can do. (With weight limits, adding anything would have meant removing other things.)

On one hand, I'm happier that way; on the other hand, it would grab people more viscerally if they could see the rover driving around on Mars.

One of the things included in the software update is improved panorama program, so it will capture more of the sky and mountaintops.

My guess would be lack of a proper atmosphere. As well as a lack of energy to power such a vechicle for very long. Guessing the rover also drives as slow as it does because anything else would be very inneficient.

Nope!
Entanglement + move particles at subluminal speed + read one particle != superluminal information transfer.

I don't really know anything about quantum entanglment, but couldn't it still theoretically help communications once it's launched, right? Entangle them on earth, launch the thing, and then once it's on Mars it can instantaneously send data back. Even if it hasn't been tested at such large distances, that's the direction we want to go.

Yeah spies are not going away. The meetings are after the incidents cited in the Forbes article. There are benefits and costs of any relationship. Hopefully, an approach that comes out of the middle path of honest preferences of the peoples will benefit both, and others involved too. Perhaps it is just wishful thinking.

Also:
[The scientists] entangled photons by stimulating a crystal with ultraviolet light, producing a pair of photons with the same wavelength, but opposite polarisation values.
Using these photons, the researchers copied the quantum state from the laboratory to the far station, achieving quantum teleportation over a much larger distance than the previous record of 16 kilometres.

 
Well... I know I'm daring a lot now... but come on... doesn't it look like that was water? Of course, a ridiculously small amount, but still. It's coming right out of the edges...

Blame the Chinese for acting like idiots, it the same general reason Norinco handgun, ammo, and rifles can't be imported here anymore.

(disclaimer: not a physicist)

No, because you can't determine the exact state of the particle until it is measured. So you have an entangled pair, one photon on Earth and one on Mars; you then measure, say, the spin of the Earth photon and get the result "up". Now you know that the spin of the Mars photon instantly settled to "down" as the quantum state decohered, but that doesn't help you in any way because you didn't know what the state was going to be.

The entanglement phenomenon has been tested a lot and we can do some nifty stunts with it, but information transfer is sadly a no-go. Quantum teleportation in this context basically means transfering the state of one system to another, and you still need to ship some classical, i.e. non-quantum, bits over to do that.

It creeps me out a little knowing Curiosity is the only active thing (to our knowledge) in such a desolate place. I can imagine the noise of motors etc echoing out much like the beginning of Star Wars when R2 is roaming about.

It's not the only active thing. They should do a Rover party! Or pictures of each other (not possible, but would be cool);)

I was out of town since Thursday! Did I miss anything amazing (I'm sure I did)? I'm going to read the last page of the thread, but if anyone has caught anything I should know about, please post. :)

Kinda OT, but I caught the Perseids on Saturday night/Sunday morning, and man, amazing stuff.
 
Looks like NASA airbrushed something? I'm not sure. There's definitely something there. I inverted the color of the image and there's definitely a line of something.

Probably just machine marks from the metal when they constructed the wheels.

There's another rover active on Mars that's been going since 2004, and there are 3 satellites in orbit (4 if next years mission goes well).

Looks more like water marks. The dark outlines definitely indicate that it's not "rubbed off dirt" by rocks.

Opportunity had water droplets on its body. There's even a picture showing it. I just can't find it.

Yep. And it's probably what caused the marks on the wheels too. Funny a lot of people think we never found water on Mars. There's ice all over the poles:p Ice melts, travels into the earth, evaporates, goes back to the poles, etc.

These three photos, taken at different times, show two salty water drops merging together on one of the Phoenix lander legs. I don’t know the exact reason for the green color, but my hunch is that it was added to highlight the two drops. You can see changes in other drops too. Credit: NASA/JPL-Caltech/MSSS
