Your right on. The problem is not how the travelers spend their time or how to induce hibernation. The problem is how to reduce the radiation exposure that they will encounter on such a long trip. Speeding things up will accomplished both tasks.
Close. It's actually all prospective recruits must be 50 years or older so that when they die of cancer 10 years later everyone can say it was from natural causes.

Yea but hard radiation shielding is really the problem. Sure we can pack a bunch of Al or some other material around a enclosed area and keep out the energetic ions both from solar events and from cosmic rays but what about the neutrons? We simply have to way to stop the neutrons and packing a lot of shielding around the sleeping area will no doubt increase the number of neutrons that the travelers would absorb. Talk about keeping them busy during flight is a nice discussion for Martha Stewart but the one of the hard core science questions (besides how to get back off the Martian surface) is how to keep them from getting cancer during the trip.
I don't and never will buy that fallacy. We are suppose to believe that we have the worst school system in the world (well almost) and then all of a sudden when one enters the workforce we work harder/smarter/better/longer then everyone else in the world. Blah...
I work with a lot of different people from many different countries and have nothing but the highest regard for my international colleagues. Whether it's France/China/Germany/Russia/Greece/Spain/England/J apan (in no particular order and not intending to leave anyone out) they work hard now, they worked hard then, and I'll have to put in even more hours if I want to keep up with them in the future.
Yea. That was the first thing I did was disable the blocking function altogether. Seems to have no effect on this problem.
I have no idea what (OWA) means but our admin certianly did setup a separate window that pops up for composing the new messages and replies. Problem is that window never pops up when I use firefox?
I have been using Firefox/mozilla for a couple of years now and am quite happy with it thank you very much. However, when I try to access my email account from home or on the road I have to put up with Microsoft Outlook Web Access (company choice I guess).
With Firefox I can look at email but I cannot respond. I hit the respond button and nothing happens. When I then log in using IE everything works fine and I can reply to my emails.
Does anyone know about this problem?
Is this a setting in my Firefox browser that I don't have set correctly?
Any suggestions?

It's not the solar wind that you have to worry about, at least directly. It's the Galactic Cosmic Rays (GCR) and the Solar Energetic Particle (SEP) events. The thick atmosphere does a pretty good job at reducing this type of "radiation" but with a decreased magnetic field and possibly thinner atmosphere we might expect more of this "radiation" to reach the surface. Everyone understands the rest of the story.
Without any funding of its own, the presidents exploration initiative is like the NIH deciding that penis enlargement is what it should focus on. Oh sure, everyone wants a bigger penis, until they find out that cancer research, heart research, etc.. all got dropped to pay for it.
NASA funds a lot of good science and a good fraction of it is in serious jeopardy because the money is being pulled away to fund the exploration initiative. Want to venture a guess to what program may be hit the hardest? It's the Earth Sciences.... "But wait", you say, "aren't those the guys who study stuff like global warming". I wonder why that's happening... I wonder....
Kind of depends on how you want to define the edge of the solar system. The heliopause is only the inner-most boundary, not the outer. The outer boundary would be the bow shock (if there is one) or perhaps even the hydrogen wall that is just outside the bow shock. In any case V1 is a very, very long way away from being in interstellar space.
Your absolutely correct. It gets down to the basic problem in space science and that is how to market information to the public. What gets me is that I can turn on the discovery channel and watch hour after hour of Palio this and Volcano that (all very important areas of research, I'm not dogging them). Why arn't there more programs made that describe the current NASA missions, design and development phases, the mission it self. Some of the great science that comes from it etc.. I guess it comes down to the fact that the Fe/O ratio is just not as cool as a Raptor claw.
The more you understand the observations the more compelling the evidence is and there was certainly no problem with any of the relevent systems. In addition the time period you refer to was certainly not short lived. The duration was on the order of months. The solar wind instrument on V1 failed a long time ago so there is no direct observations of the solar wind available. However, energetic particles also sense the solar wind and these particles are measured. The solar wind velocity can be determined from the particle anisotropies because of the compton-getting effect, to within around 20%. And it's the observations and analysis of these particles that is at the source of the reports. There is certainly no agrement on this issue yet but it is an extremely active area of research.
What is sad about this whole issue is that after a very long mission and the first real interesting observations in a very long time both V1 and V2 are in jeprody of being shut off by NASA. The presedential proposal to go to mars is not being funded at all at this point and therefore to fund the beginning phases of this effort the necessary funding to these (and many more) missions may be cut. But I guess thats typical government waste... Send the damn things out to 90 AU and then turn them off for political reasons, just when things are getting interesting.
"the Astrophysical Journal (ApJ) costs ~$250 PER PAGE for the author"
Sence when is $250/page expensive? When a research project takes 6-9 months of your life to perform and write up (or more), 2K for a 10 page paper is well in the background of what the science cost to do, from start to finish.
I'd wager that the ammount of money spent paying scientists salarays while they read/. (etc...)would cover well over 1 paper/year.
"Also the reason it costs money to publish these things is because someone with high level of expertise has to spend a lot of time reviewing the paper"
If I made money of reviewing papers I'd just retire from science and review all day. I dont know of anyone who gets paid to review papers. It's just "service" to the community. Most everyone I know reviews papers over the weekend at home free of charge.

Because solving it with a "calculator" is a one time shot. What I really said was with a computer.. numerically... but in either case.. a one time shot. It's not a transferable Solution. When I get lucky enough to actually pound out a set of equations, derived From basic principles, that is when I know I understand the problem and have produced A real solution.
Don't take my word for it. In almost every field of science the solutions that can be expressed through derived equations are the ones that get used, over and over again.
Sure, there are many papers that express a solution to a problem via computational Techniques, but they are not used as much, not cited as much, and are much more Prone to error and interpretation then is a solution that can be expressly stated with "math".
I'm not down-on-tech but I've seen way to many hot-shot university engineering Students that honestly can not do long division.

This country, and the whole world for that matter, is failing miserably at teaching kids (and adults) math. I have a BS in Physics, a BS in Math, a MS in Physics, and a PhD in Physics and my math sucks.
Seriously. I mean to most people it would seem like my math skills are great. Sure I can solve all the problems in any algebra or calculus Book. I can tutor our country's "best" engineering students through whatever courses they are struggling with. I can even rack off most DE problems with limited effort. But that really isn't the point. When push comes to shove and I try to sit down and come up with the equations that will solve the particular problem I'm working on I really struggle.
In contrast when I take the same problem to a 65 year old colleague I work with and explain my situation he can rack out a couple of pages of brilliant "math" in an hour that would have taken me two weeks or more to develop. And why? Because he really learned math and I didn't.
When I look at a problem I don't think... I can model that with a series of legendre polynomials" Or perhaps " Bessel functions would work best here".. but I damn well should. What I think is.. I will try to solve this numerically. And why.. it's because of that damn graphing calculator that I was forced to use through all of my math courses.
Close.... APL (who built messenger) actually uses an SCO product.
I use Bill as a desktop but when I need to do any real work I log on to one of our many Linux systems and guess what...."Vision" (I think thats it's name) or something like that is what we use for X windows software and it's an SCO product.
So what I'm saying is simple.
When I need to do a detailed simulation on a Red Hat Linux system the results are presented to me through an SCO product on a Windows system.
Get serious here. I publish in both types of journals and I much prefer those that are open. The little bit of money ~2k that it costs me to publish a paper verses the exposure that the paper gets in an open journal is significant.
"usually by con artists" come on now. The (e.g. astrophysical journal) is a widely published peer reviewed journal that has all articles on the web for free download via pdf files.
I publish in ApJ as often as I can because more people read my papers.
It's not the money, it's the exposure..
More visibility == more funding opportunities.
