Well ok, that would be resetting in a large crunch and destruction of matter itself, but if we don't take that into account, then entropy will grow forever.

I'd say it goes beyond physics.

We had a few moments to enjoy zero G liquid oxygen tank interior. Very nice, like some magic portal.

For Questions That Don't Merit Their Own Thread

Got this on Facebook. Interesting, huh? http://i60.tinypic.com/33ndggl.jpg Will they die or not? -
Destruction depends on the heat capacity of the part. Tiny strut will blow up faster than those large tanks.

I use sepratrons placed on the boosters between them and the first stage. Then I tilt them a bit so that they push up and radially away. Also, their center of mass should be at or below the decoupler. Never had any problems with such design and I always get a Korolev cross. Back when we didn't have offset tool to push them a bit to hide their pointy legs, I'd use Procedural Parts' procedural booster. I'd make a tiny one and save it into subassemblies.

The Ministry of No Better Things To Do has commissioned engineer Bill Kerman to go on a one man assembly mission to Kron 3. Due to the budget cuts to make the flagship feasible, he was given this vehicle. Downsides are that it nearly destroys itself over mach 1, poor upper stage TWR and a lack of RCS, but it reaches the ship and that's the most important thing here. Bill is approaching the giant ship. Every strut anchor requires a small journey using the jetpack to retrieve them from the ship that brought Bill into orbit. This is what Kron 3 looks right now. On the very left you can see the temporary module which will be replaced with a propulsion one, turning the already giant ship into a lot larger one. Bill returning home after a hard work.

His name is Rock.

If you mean the system, then yes, it can. Refrigerators, evaporating brine, organisms, they're all reversing system entropy inside their own borders, by increasing (a lot more) entropy of the surroundings. Total universe entropy - never.

The physics load happens at 2.2 km as usual. What I've noticed is that if you have your craft rotating and you switch to another craft inside that radius, the first one stops rotating. Any angular momentum is preserved in 200 m radius exclusively. What is happening? Stock or not, it's the same. I don't like it.
-
The title is pretty much self explanatory. When you approach a vehicle, first there's the lag at 2.2-2.3 km because of the actual rendering which starts to happen at that distance. But ever since v0.9, even more serious lag happens at the 200 m barrier. If the total part count is considerable, it can even crash the whole game. I've noticed this immediately after the upgrade back then, but never reported it. So, what happens at 200 m and can I avoid it?

Why is everyone talking about this? What ethical implications? There are body donors everywhere. With that said, a successful body transplant (it's not head transplant, because the head is the main unit) will not occur perhaps during our lifetime. Fixing the spinal cord is... it's just too much to even think about. Even with that solved, there will have to be an extensive therapy, both pharmaceutical and physical, to actually connect the hormonal and nervous functions. Nope, won't happen any time soon.

What was you first contact with internet?

End of 90s in a public library. It was short and shy. -
We're not talking about minors (legal issue, consent, etc.) so abduction is something done to a person against their will.

If you're comparing this to martian polar caps, remember that that's dry ice under carbon dioxide atmosphere and that there's a cycle going on of continuous sublimation and deposition. It's a system in balance, for most intents and purposes. Ceres doesn't have an atmosphere as a stable stratified system. Ice is under practical vacuum. That's an opened system. Particles escape. Take a look at this diagram. At almost zero pascals, solid-gas equilibrium exists at let's say -60 °C. However even at lower temperatures ice sublimes just like liquid water evaporates below 100 °C. I've found out that current measurements from Earth indicate the maximum temperature on Ceres surface to be -38 °C. That's way more than you need for ice to go away in vacuum in a relatively short amount of time. Check this out. http://www.ifa.hawaii.edu/~meech/a740/2006/spring/papers/PPV2006.pdf Ceres is at a distance of roughly 2.8 AU and below 5 AU there can't be indefinitively stable vacuum exposed ice. This is why these bright spots could be ice only if they were made very recently (like, within a few years or less) which is an extremely low probability event, or - more reflective rock. I go with rock. No, I don't know if this is a NIR image. Maybe it is not. Thing is, if we took that material into our hands and looked at it at normal white light on a white surface, it would be gray. Not white. Ceres is a very dark body so these spots are overexposed.

I thought with a hammer, but you can use a glass cube, 1 cubic metre. That should do it. To the laboratory!

It works fine for others and me... Try searching on Google if you can't open it from here.

I just thought you'd appreciate this comic series by Jon Adams. http://chiefobrienatwork.com They really should've given him a chair or something.

True, but try smashing a gorilla.

This is a meaningless question. Abduction means that you don't want to be taken away. If you want, it's not abduction anymore.

There are some materials which look pitch black to us, and are highly reflective (and show up as white on b/w representations) in near infrared. Some plastics around the house are like that. My backpack, for example, which is made out of some polymer. Some types of plants have striking differences in those two spectra, too. That said, it is possible that there are rocks which display high absorption in visible and high reflectivity in near infrared, but we don't know what kind of Ceres image we're looking at. Blame NASA for causing confusion...
-
Near infrared has almost nothing to do with the body's heat (at least at expected temperatures and not things like lava). Consider it to be red so deep we can't see it. The heat rays have larger wavelengths. Also we're talking about reflected spectrum. Ceres' emission spectrum is in weak radiowaves like any other cold lump of rock. This material is not white, just like 67P Churyumov-Gerasimenko is not light ash gray and I wish that NASA actually explained those things in image captions instead of creating disinformation. Therefore, we're not seeing fresh ice, but gray material excavated by the impact. Take a look at this lunar example. What about the other spot? Compare with this lunar crater. Material can slide away and reveal lighter surface, especially when there are ices locked and now dislodged and disrupted, which sublimate and leave unstable terrain. For this to be very rich in ice it would have to be VERY fresh crater. Ice would sublimate away quickly because it's not in a permanent shadow.
-
Remember that those "very bright" spots are actually rather dull looking. This is not a true representation of what we see with out eyes. I just hope we'll get true color images and not just near infrared. It would be a terrible shame if the probe wasn't capable of that.
