SSBNs stay submerged for 6 months at a time. I don't think the difference between 6 and 8 is enough to matter.

Umm, no. I served on USS Kamehameha. SSBN 642. Two months and change out, switch crews, repeat forever.

Many subs have had smaller crews, and nearly all of your interactions are with a few people at your work station.

While virtually all subs had smaller crews than modern SSBN's, they seldom had crews fewer than 30 or so. Notable exceptions being an assortment of "minisubs" used at various points in WW2, all of which spent a couple days underway at a time.

And it might surprise you to know that you seldom socialize all that much with they guys at your workstation. When you're working, you're too busy for much in the way of social interactions. You interact socially with the guys on the messdeck during meals and movies (when you can stay awake to watch a movie).

Note that one of the biggest problems with a trip to Mars is likely to be boredom. Six of you in a freefall can. No course changes, no repairs, not much in the way of science to do till arrival.

Mind you, a lot of that can be fixed by sending a bigger expedition - 60 guys plus instrumentation and such for doing some decent science while underway, that sort of thing....

But there is another huge psychological consideration that makes a sub much more like a space flight: You can't quit.

Now this I can't argue with. A good point. Note that this makes the test even more (potentially) useful. If the guys in the dome can't handle it in Easy Mode, sure as shooting it won't work for a Real Mars mission....

I am also impressed at far some Americans are willing to go to do pointless redundant research instead of just looking at how sailors deal with life on a submarine.

We only spent a couple months at a time making holes in the ocean. Plus we had a lot more possible social interactions (100+ in a boat, as opposed to six in the dome).

So, worth the trouble of doing. Not like it's going to cost trillions (or even billions, or even large numbers of millions) to do....

The raw material might be worth very little, but I bet processed ore would be worth quite a bit.

Raw material or processed ore wouldn't be worth the bother on Earth.

At the top of the gravity well, on the other hand, it could be worth quite a lot, potentially. It's easier to reach Earth orbit from 16 Psyche than from the Earth, looks like. Takes longer, of course, but less deltaV.

And that ignores high Isp options that are available to 16 Psyche that aren't available from the ground....

Compared to risks of war

Risks of war?? Obama was, I think, the first two-term President who was at war fior every day of his two terms.

Note that Johnson was also at war every day of his Presidency, but he didn't have two complete terms. And it's possible that Roosevelt was at war more days total than Obama, but he had three and change terms to work with....

There are many many things that can be improved about this nation. But collage affordability is not one of them.

Yes, one of those things is that people could learn to spell in primary school.

Or does it really cost all that much to make a piece of art that is assembled from a variety of different forms?

Snowden should also be pardoned.

Note that Manning was NOT pardoned. His (her?) sentence was commuted. So, he/she still has a criminal record, can't exercise his/her full rights as a citizen (RKBA is gone, for instance, in spite of firearms being completely irrelevant to his crime).

A sentence commutation just means he/she gets out of jail sooner. Not at all the same as a pardon.

Back in the tycoon days you had basically unfettered capitalism. Because of that, big tycoons were able to set their way even to buy government

Umm, it's NOT "unfettered capitalism" if you can buy governments. The act of buying special privileges from the government is pretty much the opposite of "unfettered capitalism".

Do remember that the kind of government you can buy monopolies and such from is strong enough that capitalism is pretty much automatically fettered by the government. So what you're describing as "unfettered capitalism" is actually "corrupt government" pointing fingers away from themselves....

Comment Re: Unlimited? (Score 1) 196

Small cells negate the "limited amount of spectrum" argument. It's a financial + logistical + political/regulatory limitation, not a technical one.

Technology will eventually advance to the point that the financial consideration is less important. We're already working with beam-forming -- a technology that's existed for decades, in radar applications -- for instance. Wireless is the future, no matter what the naysayers think, and if you're still thinking of "spectrum" as the limiting factor you're behind the curve. Makes me think of the folks who deploy IPv6 for the first time and start worrying about the "waste" of addresses.

There's no technical reason why an LTE network can't be engineered to provide truly unlimited data with acceptable speeds in most instances. There is, however, a financial reason, plus the usual regulatory/political concerns that get in the way of new cell sites. It's worth noting that T-Mobile manages to offer unlimited with an asterisk (video throttled to 1.5Mbps) and in many cases delivers superior speed than Verizon, so it's clearly POSSIBLE and PROFITABLE to use as a business model.

In rural/fixed-wireless settings LTE is actually cheaper than DSL/cable and the favorable contention ratios (i.e., low population density) make unlimited possible with today's network. It's a mystery to me why they won't offer an unlimited product for this market segment at least; it would be the death blow for satellite internet.
