#676 Re: Human missions » How to blanket the Moon - with recon-sats » 2005-06-11 15:29:48

http://web.mit.edu/egralla/www/research … 8.pdf]This is clever, IMHO. The paper talks about Earth orbit satellites but what about the Moon?

Use the biggest medium heavy launcher available and send a single payload in one piece to L1. There, open the paylaod fairing to release as many micro-sats as can be fit inside (size and mass).

Then direct each micro-sat to a different low lunar orbit for mapping and imaging missions.

How many micro-sats might ONE Proton or Delta IVH deploy to lunar orbit for recon purposes?

#678 Re: Human missions » CEV development timeline & cost projections - Can anyone justify NASA's data? » 2005-06-11 10:37:44

The jury must remain out for a few more months.

The resignation of Admiral Steidle and the cancellation of the CEV "fly-off" he was to administer means we do not yet know what the CEV program will be. (The Thiokol stick for CEV is my guess but we just don't know yet)

Also, it appears that Dr. Griffin will announce his return to the moon architecture and CEV program details later this summer. Some say July. The O'Keefe planning process may very well be dead, dead, dead (that's why NASA execs have been reassigned or let go) and therefore we currently have no real idea what the implementation of the vision will look like.

Therefore we cannot yet judge.

The Stick, which has won support in some NASA offices, would use a new liquid hydrogen upper stage atop a recoverable solid rocket booster (SRB) much like the SRBs used on the current shuttle stack. The new upper stage could be powered by a space shuttle main engine (SSME), by a J-2S engine revived from an Apollo-era program, or by a cluster of RL60 engines now being developed by Pratt & Whitney. Varying numbers of SRB segments could be used in the first stage. Studies by Lockheed and ATK Thiokol have shown that such single-stick vehicles could orbit payloads ranging from 16 MT to 25 MT or more. The most powerful versions could actually match the payload capacity of the existing space shuttle system.

http://www.blog.speculist.com/archives/ … tml]Source link

A few months ago I told my wife I might want a http://www.cleardomesolar.com/]solar thermal oven for Father's Day. She called me at work today looking for some links on where to get one. (This guy has weird web navigation, the link takes you to a home page yet the solar oven page has the same URL - - so, just click the "oven" link at the top of the page)

Anyway, after reading about it we mutually decided that with children 900 degrees was just a little too dangerous.

The guy who makes these things said that with two 24 inch parabolic disks set to focus both mirrors on the target he melted an industrial thermometer that was rated to 1800 degrees F - - he estimates the furnace hit 2000 degrees F.

These would be awesome for the Moon if you added a Sterling cycle engine. No atmosphere and in the shadows temperatures approach, well very very cold. Those Sterling engiens should just whir right aloing if you can dispose of the waste heat fast enough.

Actually, I would prefer to by-pass the moon and go to Mars, but our President has announced otherwise. Therefore we should do the Moon with equipment that can transition us on to Mars. Rather than do the moon then go clean slate.

Anyway as for "any" potential mission, what is wrong with the "stick" as a low cost medium/large cargo carrier? What can EELV do that a 4/5 segment RSRM (with a Delta IV uppermost stage) cannot?

And, if we are into building new facilities we can build a new pad just for the stick even if the goal is to close Pad 39.

As for politics, Florida is too closely divided between red & blue and has too any crucial electoral votes for either party to be responsible for the shuttle army being fired in one swoop.

Therefore, they should be doing some useful work. Not saying I approve, I merely acknowledge that reality.

#683 Re: Not So Free Chat » Political Potpourri VI - (We crashed the last one) » 2005-06-10 09:56:37

A 4 segment RSRM topped with RL-10s (no upgrades) should be able to launch 20 MT for less than $75 million. ($40 million +/- for the solids and $35 million is plenty for some RL-10s)

Blows the doors off Delta and Atlas on price. Its down there with Zenit and Proton for that matter.

Which is why NASA should give t/Space $500 million for an alternate crew to LEO capability even if we also do parallel development of CEV on top of a Thiokol stick.

That stick can do double duty as a medium heavy cargo lifter at half the price of EELV.

NASA also needs to open up destinations. Create viable places in LEO for t/Space to visit. One shuttle C can throw a small habitable station. Skylab wa far superior to ISS in volume and that was one shot.

We cannot do more than lunar flags and footprints with EELV. Can't sortie enough mass fast enough.

In a perfect world clean sheet might be better but in 5 years the deficit will be crasing down on us. If the CEV isn't flying and if we don't have a viable plan to do something worthwhile on the Moon why should we keep the program at all?

Big rockets are the ONLY thing NASA can do that others cannot.

#685 Re: Not So Free Chat » Political Potpourri VI - (We crashed the last one) » 2005-06-10 09:36:33

Delta IV ain't cheap either. New launch pads? No room in the budget.

That said, a Thiokol 5 segment stick with improved SRBs (90/10 fuel to dry mass ratio) might be waay cheaper than shuttle C and Delta IV both.

#686 Re: Not So Free Chat » Political Potpourri VI - (We crashed the last one) » 2005-06-10 09:28:40

And if we get an al Qaeda honcho who isn't cooperating, we can still do whatever it takes behind closed doors.

Sometimes you gotta do what you gotta do. But don't enshrine that into law and create an escalating precedent on what is considered acceptable.

Further, if we state that we're voluntarily upholding the Geneva Convention we can hold these prisoners indefinately. Even after the fighting stops and we've won, who do we send them back to? If the government of the country of origin wants them to lock up or for less palatable things, hand 'em over. If not, we can keep 'em at Gitmo forever.

The key here is only half policy. The other half is presentation. This Administration isn't too good at marketing this, we can keep the terrorists locked up and show off our Western goodness at the same time.

This Administration doesn't want to compromise. On anything.

The other day Bush stuck his finger in Tony Blair's eye over global warming and aid to Africa. We can argue global warming until the cows come home but since Tony Blair does take it seriously and since aid to Africa is a major Blair initiative to shore up the support of his own party and because he is our ONLY ally in the Bush version of the War on Terror whacking Tony in public on those issues just seems stupid.

Regardless of where we "should" stand on those issues.

= = =

Bush is also playing to his Christian Right base that truly wants the Christians to smite the Muslims (and the gays and the democrats and the secular humanists and the atheists). How do we fight Bush on that if we are told opposing the president coddles terror?

The Bush strategy is to force the Democrats to disarm on the domestic agenda with the threat of disloyalty in fighting terror. And that is utterly despicable.

However, there's a fine line between "being nice" and "being wimpy".

Fear of being wimpy is itself wimpy. We have the biggest military on the freakin' planet and we are afraid of appearing weak?

Barbara Bush sure put some goofy thoughts in that boy's head.

But we can't bust heads without more soldiers. Remember my complaint is NOT ENOUGH troops in Iraq to do the job right. NOT ENOUGH money being spent on reconstruction. "Gotta appear tough" is a good way to find oneself fighting for a bridge too far.

To be "not nice" and carry a too small stick is the worst of all worlds. Weak Roman. And nothing has changed since Cobra and I agreed on that point last time.

#687 Re: Not So Free Chat » Political Potpourri VI - (We crashed the last one) » 2005-06-10 09:08:02

Someone please, tell me why EELV is better than shuttle derived.

It's not. But then SDv isn't better than EELV either. They both suck.

SDV though sucks more. Why?

Well, one, cause I say so. But really, because SDV represents the old NASA way of doing things. The one that says, “we can do better than you cause we know better.”

I think the history of NASA as a launch provider proves this to be blatantly false. NASA sucks, yes, sucks, at keeping their launch vehicles in-house.

By accepting SDV we accept that NASA is the only qualified agency to produce HLLV. They have no reason to innovate the process to reduce costs. The number of launches SDV will make ends up creating two situations: a lot of idle time where the workers and staff are kept on the rolls for the sporadic launches, or a lot of mission creep as we try to build our space program around utilizing the SDV (instead of defining our needs first).

SDV is Shuttle redux, and frankly, 30 years ought to have been enough time to learn a thing or two. What did we see with the Shuttle? Our space program morphed to accommodate it. Same thing with the ISS and the Shuttle together. We need to stop. NASA needs to get out of the launch business and become solely a customer of launch services (a basic call championed by the space community for decades now).

I fail to see how you, Bill, can on one hand clamor for the t/Space model, yet also be a cheerleader for SDV by NASA. You want to merge two ways of doing space exploration that are the antithesis of each other. You make absolutely no sense, and honestly, you should reevaluate where your loyalties lie. Traitor.

(please note that the feel of this post is directly related to the overall theme of this thread... talking about SDV in a political thread can get dirty. big_smile)

Because HLLV is cheaper for cargo IF we don't worry about man-rating the thing. The bigger the better -- something about costs increasing by the exponential power of 2 while volume increases by the exponential power of 3.

Avoid parasitic weight by minimizing the interfaces.

No crew riding shuttle C? No need to design a heavy and expensive crew escape system.

With crew, we need gold plate safety. So, get the crew up there in an ultra safe over engineered small system and transfer to the other system once on orbit. 

t/Space does NOTHING except get crew to LEO safely. But, that means shuttle C doesn't need to allow an ounce for crew safety equipment. t/Space is also safer than the Thiokol stick, in my opinion, because the stick will need an escape rocket on top the CEV, as would any ground launch system.

Air launch avoids the need for any escape rocket tower.

= = =

EELV? Not enough launch pads. Pad 37 by itself cannot sortie enough mass to LEO fast enough to do anything worthwhile.

Liquid hydrogen does not store well on orbit.

That's why I also favor methane for extedned operations. Smaler tanks and less boil-off to offset lower ISP.

And, again, the prisoners at Gitmo are likely being treated more courteously and humanely than our own native population gets in our federal prisons.

--Cindy

Cindy, if this is true, take al Jazeera on a tour of Gitmo and use Gitmo as an affirmative propaganda weapon to prove how humane we really are.

Instead we get this: "We are humane and no we won't show you and if you ask for proof you hate America."

*Could we trust al Jazeera to be unbiased?  And not pander to any sort of propoganda of their own?

Of course they are baised! What does that matter if we have nothing to hide.

#690 Re: Not So Free Chat » Political Potpourri VI - (We crashed the last one) » 2005-06-10 07:50:21

So, while it may be morally right for us to treat terrorists like proper POWs under the Geneva Conventions even though they decapitate our civilians and string up burnt bodies we'd be doing purely for our own comfort, no practical concerns. Nothing we do will lead to our POWs being treated worse by these enemies, they already have no reservations about committing what we would call war crimes. If we grant terrorists POW status we gain nothing for our troops in the field. Besides, when do we release them? To whom? If we accept that they are POWs but we aren't actually at war with a recognized power and that non-nation won't surrender we'll be holding them, in accoradnce with the Geneva Convention, until every last one expires in custody. Somehow I doubt this will satisfy the critics.

It also sets a precedent for how other states deal with their insurgents. After all many in this country support funding people to overthrow the Iranian regime.

But tell me this. What does Gitmo gain for us? What benefit?

For the record, if a terrorist knew where a timed nuke was hidden, we gotta do whatever it takes to get the intel. Whatever. But that is a special case.

By the way, how many detainees even speak English? How much of a threat are they? We will erode our legal protections and condone things analagous to a Bill of Attainder so we can imprison in secret some low life scum?

Actually I wonder if eroding the Bill of Rights is the real objective of the whole Gitmo thing. Bill O'Reilly had a segment on the other night about how much easier police work would be if pre-trial detention without charges wasn't so frowned upon by our legal system.

If our goal is to extend the western view of civiliation to include the heathen (in other words "win" this clash of civilizations) then treating enemy combatants "as if" the Geneva Convention applies - -  even if the lawyers can prove it doesn't - - would go a long ways towards convincing the rest of the world that becoming western isn't such a bad choice.

Gitmo is (a) corrosive to our ideals whether legal or not; (b) a lousy way to actually acquire useful intel; and (c ) undermines our efforts to build a positive image of the West

Half-serious.  And it doesn't matter, as you're much more politically savvy than I could ever be.

Its either (a) or (b) - - > the Gitmo detainees are criminals and the Constitution applies OR they are Prisoners of War and the Geneva Convention applies.

Things are rarely that easy.  The constitution does not apply to non-citizens outside the US.  The Geneva Convention does not have to apply to combatants who refuse to meet it's criteria.

Forget the lawyer arguments. Those principles SHOULD apply to everyone, everywhere unless America really stands for "might makes right"

Read the Declaration of Independence. Read the Preamble to the Constitution.

Our rights do not come from the Constitution, they come from pre-existing rights the Constitution was enacted to preserve.

Human rights that Thomas Jefferson believed were the inalienable rights of every human being, anywhere on the planet, or who may travel to Mars for that matter.

= = =

In practice, the legalities of the Constitution do not apply outside the United States, however the principles must, always and for everyone. No exceptions.

And Gitmo sets a terrible precedent for the future treatment of our POWs with the world saying in that case "what goes around, comes around"

= = =

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. --That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed

If we deny human rights even to the most vile terrorist we undermine our own moral legitimacy. And to assure that is happening we need transparent access to Gitmo.

http://www.cnn.com/2005/US/05/10/buffet … tml]Warren Buffet agrees. It really is a class war, launched by the wealthy.

BUFFETT: Yeah. The rich people are doing so well in this country. I mean, we never had it so good.

DOBBS: What a radical idea.

BUFFETT: It's class warfare, my class is winning, but they shouldn't be.

DOBBS: Exactly. Your class, as you put it, is winning on estate taxes, which I know you are opposed to. I don't know how your son Howard feels about that. I know you are opposed to it.

At the same week the House passed the estate tax, Congress passed the bankruptcy legislation, which they had the temerity to call bankruptcy reform, Democrats and Republicans passing this legislation, which is onerous to the middle class. Half of the bankruptcies in this country take place, because people fall ill, serious illnesses result in bankruptcy. Nearly half of the people involved. How do you -- you have watched a lot of politics. What is going on in this country?

BUFFETT: The rich are winning. Just take the estate tax, less than 2 percent of all estates pay any tax. A couple million people die every year, 40,000 or so estates get taxed.

We raise, what, $30 billion from the estate tax. And, you know, I would like to hear the congressman say where they are going to get the $30 billion from if they don't get it from the estate tax. It's nice to say, you know, wipe out this tax, but we're running a huge deficit, so who does the $30 billion come from?

Good comparison to the Bill of Attainder by the way. However, you don't seem to have mentioned that it is specifically banned in the US Constitution. If a court were to decide that the "terrorist" class is in effect a bill of attainder it would make it unconstitutional.
