first of all, any high energy protons that come into the region around Earth are deflected by our magnetosphere. At worse, nothing happens. At best, you get pretty lights in the northern sky. Second, the particles aren't necessarily travelling at relativistic speeds, you are (when travelling at velocities approaching c). From your perspective, you're in a sea of relativistic protons even if they're standing still.

So close... and yet still a freeking impossible distance away.

Oh.. it's just 11 light years away. That's a small number, right? As much as I'd like to be able to say we have a "warp drive" or "jump drive" or something like that... at the moment 11 light years might as well be 11 million light years. it makes no difference to our ability to get there.

1. we don't have the technology to achieve that. 2. without some as yet to be thought of technology, the relativistic relative motion of the incident protons, even at 1 per cubic meter or so, would interact with the vehicle structure and create showers of particles, killing the crew.

Her experience is actually not at all uncommon. Many astronauts report being uncomfortable for extended periods because of the shift in fluids messing with the body. Nausea is not uncommon because the middle ear ends up filled with fluid and there's no "down" for the vestibular system to reference. People in extended missions find they suffer from discomfort of muscles and joints. They experience vision changes and bone loss. The human body is just not adapted to zero G. Some never adapt; but, astronauts being a group of over-achievers by definition, the hide the symptoms and don't report them.

No one's going to actually go in and look at the reactor (or what's left of it) for a long time. What it does tell us is that most of the fuel is in the bottom of the containment vessel, and not hanging in the reactor pressure vessel. While TEPCO how they will use that information today it will affect their decision making process as they move forward.

Sorry. coding 8-bit, 32-bit and 64-bit embedded, as well as desktop apps. You missed the point. parent said

go out and buy another gig or two of ram for a few bucks. seriously...its hard enough to find professionals to build software without getting bogged down with mallocs and leaks for god's sake. when java first hit in the 90's, prettty much the #1 feature was its automated garbage collection...why now are we debating this now?

The reason I'm arguing it's important is that there are still a lot of applications out there where dropping in another gigabyte of RAM isn't an option. Embedded doesn't always have gigabytes of memory; sometimes your cost constraints put you in a 25 cent processor with kilobytes of memory. I'm coding 8-bit processors because I write code for embedded application which are cost sensitive. I'll use a 32-bit processor if the design specs show it's called for.
