OK, so, water is just the ashes of oxygen and hydrogen burning together, OK? Burning together roughly the way we burn them in conventional rocket thrusters. So, in order to succeed, the recipe will be:
1) get to icy asteroid, mine it, get water
2) magically turn back the water into its original components, before burning: O2 and H2 (???*)
3) burn them again together in your thrusters, and profit!!!
(*) yes, you can use a solar panel. Just let me bet that the mass of solar panel + water extractor + electrolysis apparatus is larger than the ordinary, earth-brought mass of fuel that'd bring the same thrust.
Sorry to be skeptical folks; please, do go playing with your asteroids while I develop actual, usable rocket science;-)
It would be a freaking miracle if Opera Mobile (the complete Opera browser, that exists for ALL smartphones but Apple's) would be accepted on the iPhone. But indeed, Opera didn't even try to propose it. They dared propose a simple remote viewer, Opera Mini.
Contrary for instance to my Nokia N97mini which features the original Nokia browser and let me replace it with Opera Mobile, the iPhone is probably the only platform where no other browser will be allowed (nor even proposed).
Opera Mini is indeed a simple viewer for images remotely calculated on Opera servers.
This has the advantage of lowering the data transmitted to your phone (actually cost-effective if you are volume-limited), and the disadvantage of providing some unexpected behaviors whenever local things like active buttons etc. are expected to be loaded on your device (I say *some*)
In fact Opera also offers a full browser, named Opera Mobile, on all sorts of phones (on my Nokia for instance, aside Nok's one), but that one, Mobile, isn't ported on the iPhone. Wonder why;-)
The title says it all, we've had to show an ID card for each SIM bought for years (by this I mean, before our security-overexcited current president even appeared)
The energy cost here won't be in the device power requirement, it'll be in preparing the glue. Think about the energetic cost of cement for instance, now consider the "super-glue" used is an even more ambitious cement...
This not to say potential alien life may just have a different inner clock than ours, and for instance find us 100 times too slow to even talk too.
More generally, I find our current defintion of "aliens" incredibly human-like (same molecules, same "habitable zone", same **thinking**...)
Indeed I trust only a few years from now, our SETI-thing will be considered as silly as, some centuries ago, "angel's sex" discussions within the religious sphere in the Middle Ages, or the definition of green-skinned martians everyone commonly had just a couple of years ago...
GPS underground? I'd rather imagine robots equipped with accelerometers, ie a technique that'll start getting errors in the % range after just some m...
Can't you solve this just with an optics dealigned wrt the camera CCD? This is the way used, for instance, to get buildings straight while they are imaged from a point where obviously the perspetive would deform them entierely... I think it is called 'axial correction' or something alike in ordinary photo, see for instance http://www.mir.com.my/rb/photography/hardwares/classics/olympusom1n2/shared/zuiko/htmls/35mmSHIFT.htm , by the middle of the page you get impressive examples... (of course this is an hardware solution, so even as a simple one it should probably banned on/. )
Very very long indeed. I understand the timescales in TFA are in million to billion years, so the frequencies photonic expects to detect would be conversely so low that this'll just be a constant at our timescale... I fear we'll not see a turn;-)
... the fact that Apophis just has no chance to hit us is, I fear, irrelevant. Even though its trajectory has been known for years to be safe (and safer with the latest measurements), what seems to count now is the psycho-TV impact of the announcements. So, "saving us from Doom" is of course much more efficient than real scientific activity, 'more' like in 'more capable to gather money' presumably.
To some extent this is not unlike the current rush for EXOPLANETS in the related Astronomy field. People seem to consider you'll dream better of Earth-like planets (unusable objects that lie unreachable thousands of light-years away) rather than considering actually useful scientific experiments.
One of the most striking story on that point was the french COROT satellite, initially set to study our sun's convection and rotation modes (thus the name: Co-Rot, and a real interest to us), then someone discovered the same instrument also could be used to detect exoplanets, then half of the satellite payload was accurately adapted for this, then in the french space agency it has become THE exoplanet chaser. It's to the point I'm now wondering if the science of the sun is actually taking place in parallel. Never heard of it.
The worst of it is, everyone agrees (myself included!!) that the Corot mission would never have been funded uo to the end without this exoplanet stuff...
To some extent we don't need 'the Bell curves' to find cynism in Science:-/
I don't know for the rest, but on french TGVs a stop is 3mn max, not 10. And yes it works, I checked it again some weeks ago. Doors are large, and local controllers (that stay in the station) are very active just before and during stops.
You are raising a very interesting question, at least for the average engineer I am:-)
What you are suggesting is, while Schrödinger was dealing with microscopic events (the cat's box was explicitly only an analogy), one may turn it large scale by replacing the request for isolation by a request for distance only.
Now, I'm not sure an actual quantum physicist wouldn't answer you that because of the presence of possible alternate observers, the Huygens module quantum state probably would have to collapse in due time anyway.
In other words: maybe it won't work because of Martians;-)
indeed the reason for the Cassini/Huygens mission over there was to analyse what was called a "frozen Earth" at the prebiotic stage. Titan's size and atmosphere thickness is definitely comparable to ours (and the only one in the solar system), it just never got the necessary energy to start things up...
indeed on Titan the ground rocks are constituted of almost pure water ice, and over there ice just will be rock-hard forever. The pebble on these Cassini-Huygens lander photos are ice: http://www.esa.int/SPECIALS/Cassini-Huygens/SEMEMY71Y3E_0.html (visible on the orange vertical image that is the "last photo" Huygens took once on ground) Hervé
Actually it's one and a half hour away. At light' speed, I mean.
I happen to have been tech resp. of the european Huygens probe that Cassini brought to Titan, and what I remember the most from the time of Huygens descent and landing years ago, is this feeling that all the active descent has *already* happened, while here on Earth we didn't yet have received the first bits of info, radiowave that were still into the travel.
Indeed that was a very real way of measuring distance. Saturn definitely is not close...
