I propose this thread be about the new architectures that should start flowing out of NASA over the next few weeks.
This website claims to have exclusive info about the new architecture. I offer the link for your review, assessment and enjoyment.
Anyone visit NasaSpaceFlight.com before today?
T.L. James has blogged today's speech by Chris Shank at the Mars Society Convention.
More details as I discover them.
Folks, please meet Maryscott O'Connor.
Quite the flamethrower. :shock:
= = =
Maryscott O'Connor (orphaned by a senseless war) and Cindy Sheehan who lost her son in war started on account of lies will be the avenging angels that will cleanse away the followers of Republican Jesus.
Ehhh almost... Griffin is still a bit weak in two areas:
-Does he have the force of will, if the cards were down and that there is no other option, to decide and defend said decision to lay off large numbers of unessesarry NASA personel if he had to in order to make ends meet. Does he have the force of will to stand before congressional science committees or aerospace corporation sales staff and tell them "no."
http://www.nasawatch.com/archives/2005/ … _un.html]A hopeful example?
-Has he taken the only viable position for exploration that the International Space Station is a lost cause, and only the minimum political face-saving construction and operations should be carried out there. Furthermore, absolutely no future Moon/Mars hardware must be a concession design on the account of futily trying to make the ISS useful.
Shifting ISS crew & cargo transfer to t/Space (after they perform without NASA development money) seems to answer this.
Okay Griffin, the situation is as good as its ever going to be. Make it happen.
Thus far, not too shabby a performance for Jedi-Mike. Presidential support. Solid bi-partisan support in Congress. Got the Pentagon on board. (No Delta II will cut into lower price science missions, but so what? in the big picture.)
AND!
Mike Griffin goes on "Meet the Press" and tells Russert that it's human destiny to settle space and he wants Americans to be part of that.
Thus far? It's pretty much all good.
Space.com reports shuttle derived is a "done deal"
http://www.space.com/news/050810_dod_la … l]Pentagon & NASA agree
The two-page letter says “NASA will initiate development of a Crew Launch Vehicle derived from Space Shuttle solid rocket boosters with a new upper-stage for human spaceflight missions in the 25-30 metric-ton-class following retirement of the Space Shuttle in 2010. NASA then plans to develop a new 100 metric-ton-class launch vehicle derived from existing capabilities with the Space Shuttle external tanks and solid rocket boosters for future missions to the Moon.”
The letter also says NASA and the Pentagon will use the Atlas 5 and Delta 4 rockets developed under the U.S. Air Force’s Evolved Expendable Launch Vehicle (EELV) program “for all intermediate and larger payloads for national security, civil, science, and International Space Station cargo re-supply missions in the 5-20 metric-ton-class to the maximum extent possible.”
A shared understanding of what it means to be "American" might help.
:?
What if this ". . . a means of intercepting incoming nuclear missiles . . ." is not technologically feasible?
Besides, block our oil imports and a missile attack becomes unnecessary.
Cindy, you ask what do we do. We "triage" the threats we face. We forge genuine alliances and we read Thucydides to learn how NOT to treat our allies.
= = =
In a civilizational conflict, the Anglo countries are easily united. US, UK, Aussie-land. After that we need allies. ALLIES not subordinates. Therefore we need genuine diplomacy.
Europe is our BEST potential ally. India is #2 in my opinion.
Agree to disagree with Europe over stuff like 35 hour work weeks and nanny-state health care. Be open to the idea that police work and intelligence ops might be the best way to fight terror.
= = =
DO NOT forget South America.
If we mess with Chinese oil flowing from Iran, they might mess with oil flowing from Venezuela. Chavez inviting in the Chinese military would be a nasty thorn to have to pluck, especially if Saudi oil was also threatened for other reasons.
Therefore job #1 has to be ALTERNATIVE ENERGY!
Cobra, if you are saying that some nihilistic murderous 13th century al Qaeda gangsters are a much smaller threat to that project we call "Western Civilization" than the Chinese and the Russians, then I'd say;
"About effing time!"
Nation-states? I am still fond of Samuel Huntington.
Interesting analysis on why Iran is rattling the http://www.grokyourworld.com/louisxiv/2 … ml]nuclear saber.
If during the settlement of the Iraqi Constitution, the US pressures the Sunni & Kurd to accept pro-Shia concessions (in order to undermine potential Iraqi Shia support for Iran) Iran says "OK" and agrees to stop enriching uranium.
The Mars Homestead project is doing pretty much exactly what Mundaka proposes.
Robert Dyck recently made a somewhat worrisome observation. The surface of Mars might be covered with asbestos.
Ouch!
I doubt that corporations will ever see enough potential profit on Mars to fund a colony, until governments on Earth have done the heavy lifting.
Of the governments that can do the heavy lifting, the question is which ones will? A government like mine here in the U.S. might do it, but these days only if you can link it with fighting terrorism -- fighting communism is just too passe.
![]()
The reality is that Western politicians are dependant upon what they can get for their constituents and so think short-term (like the pork-trough dwellers they serve.)
The alternative is a powerful, but totalitarian government that could colonize Mars or the Moon either as a propaganda coup or for a percieved military advantage -- but would you want to live there?
My bet would be on a major world religion. But that is old news, for me.
While culture can't be "created" through politics, it can be molded by politics. Unfortunately it's not just a matter of smashing socialist government programs. The problem isn't just government centralization but centralization generally. Large centralized corporations are just as damaging to both the social and economic welfare of a people as large centralized governments are.
Which was all well and good in colonial times but how can any of this apply now? Modern industry requires centralization, both in manufacturing and in regulation doesn't it? Sure, but we're also approaching a point where that could all change. We're rapidly approaching getting to where individuals will be able to make whatever goods they want with some modestly priced equipment. This doesn't even require nano machine uber-tech but simple industrial "fabbers" of the type that are already in use for prototyping. Manufactured goods could be made anywhere to exact custom specifications with technology that is on the near-term horizon. Entertainment can already be produced and distributed by artists themselves without the need for big corporate entities and it will only become more widespread. Farming has been practical on a small scale since the earliest glimmers of human civilization.
In short, we seem to be approaching a level of technological development where we won't need these big centralized entities anymore. Aside from the basic functions of government (maintaining social order, protecting property rights, etc.) none of the rest matters. If we start paving the way now we may well be able to return to a more self-reliant and historically and socially aware mentality similar to that of this nation's founders, only for everyone. All the comforts in less time with less effort. Plenty of time for more intellectual pursuits for those so inclined. Not a utopia by any stretch, afterall someone still has to kill the cattle, ship the meat and take out the garbage, but a world with more leisure time and more freedom than currently.
I totally agree with large swathes of this.
I also believe the Libertarian Left will embrace this more readily than the wealthy Right since the (relative) demise of large corporations will "gore their ox" far more severely by making the concentration of wealth more difficult.
Not exactly a web sig, but I hear it is making the rounds in Iraq.
It's better to be judged by 12 than carried by 6 - - If my kid was over there, I'd say "Damn straight" you take that advice, son.
But, bigger picture, if we do adopt the old VC mantra, If he runs, he's VC; if he don't run, he's disciplined VC how can US forces possibly establish a civil society?
= = =
Here is a web sig:
"I've got no problem with God. It's his followers that scare me!"
Stop D-Day AND stop the air campaign and perhaps the Soviets gets stopped when the Western forces along with a million people commtted to air defense move eastwards and set up a defensive line. Stop the bombing and the Luftwaffe turns east as well.
Pretty much agree with this as well. Simply postponing D-day probably wouldn't have given Germany enough breathing room to halt to Soviets. But an armistice with the Western Allies very likely would have.
A dozen A-bombs and Stalin might have been deterred. Two A-bombs and the Soviets would have come on even harder, in my opinion. In 1945, the USA did not have a dozen A-bombs.
Very difficult to say. Stalin probably would not have been deterred by a couple nukes, but the Red Army is quite another matter. They weren't quite the monolithic, loyal communist force bent on the destruction of the Hitlerite invader that they were made out to be. It was quite common for advancing Soviet forces to have another line behind them not for support but to shoot them should they try to flee. It would not have taken all that much to crack the rank and file. Particularly if their allies (namely us) withdrew support.
= = =
Which poses the "what if" question.
In June 1944, Hitler has 2-3 A-bombs with maybe 1 more coming 6 months thereafter. When and where can they be used to best change the outcome of the war?
My answer? The Normandy beachhead a few days after the landing, seeking an armistice. Late last night I was reading about the Mulberry artificial harbor that were landed 9 June. Perhaps a few days of delay to let more Allied forces ashore before dropping the bomb would have been better for pushing for a western Armistice.
As an aside, I was reading about the undersea pipeline built from England to France to fuel the Allied soldiers. The Normandy operation saw a tremendous number of technology advances.
-- Incidentally, I followed the discussion, with interest, between Cindy and CC about the Japanese failure to capitulate after Hiroshima and before Nagasaki. But I'm not sure there actually is any correct interpretation of those events because it may not be possible to see the situation from the perspective of each side after such a long interval. Maybe there is some truth in the suggestion that Japan didn't believe America had a second bomb (?). Who knows?
My recollection is that the emperor and the military (Tojo) disagreed about surrender. Hiroshima and Nagasaki helped the emperor win the argument.
When the emperor told the citizens to surrender and not resist the occupation that made our job significantly easier. Had the emperor said "Fight to the last man, woman and child" and then been killed by US bombs we might be fighting a Japanese insurgency today. At least into the 1950s.
Operation Bagration was launched June 22, 1944 with 1,700,000 Russians attacking 800,000 German defenders. Army Group Centre was destroyed, utterly. In July, 1944 the Red Army drove the Germans entirely out of the Ukraine with several hundred thousand german casulaties and prisoners.
During that time period, about 20% of Germany's total military forces were in the West. To delay D-Day might have freed up a fraction of those numbers. Not enough to stop the Soviet onslaught.
Postpone D-Day and Joe Stalin ends up in Belgium, Holland and France.
Germany did have two million soldiers and civilians committed to air defense against the RAF and US Army Air Corp. 10,000 AA guns including many thousand 88 mm which were superb anti-tank weapons.
Stop D-Day AND stop the air campaign and perhaps the Soviets gets stopped when the Western forces along with a million people commtted to air defense move eastwards and set up a defensive line. Stop the bombing and the Luftwaffe turns east as well.

I think Truman made the right choice at Hiroshima and Nagasaki, as the lesser of evil options. Many more people would have died had we attempted landings on the Japanese home islands.
If the plan is to vent excess heat into surrounding regolith (far enough away not to melt any high water content regolith under your hab) might the temperature differential be sufficient to run Sterling cycle engines?
It seems to me that a sealed system is essential with coolant running through a closed system in any event.
Alternate history scenario involving Mars.
A pair of A-bombs are dropped on the Normandy beachhead on 7 June 1944 or 8 June 1944. The invasion is crushed.
Hitler tells FDR & Churchill, accept an armistice so I can stop Stalin. Otherwise, Stalin rolls to the English Channel. US & UK agree and turn to pummel Japan into oblivion. LendLease to Stalin ends.
With the air war ended (in exchange for Hitler recalling his U-boats and NOT dropping A-bombs on London) Hitler transforms tens of thousands of anti-aircraft batteries into anti-tank units and forms defensive lines along major rivers in Poland and southwards. Fighter plane units that had been attacking B-17 formations now turn east as well.
Hitler builds more A-bombs as does the USA and a Cold War develops with London held hostage and eventually the Red Army is stalemated, even if the Wehrmacht cannot resume eastward movement. Italy becomes "Occupied Italy" and "Free Italy" - - think NKorea and SKorea. World War Two never officially ends with an uneasy truce along the English Channel & North Sea.
US & UK begin fighting the Soviets near Vladisvostok and on the northen Japanese islands. US A-bombs help as do the thousands of aircraft based on US carrier battle groups and later in Japan itself.
George Orwell's 1984 arrives 30 years early, when Stalin gets the A-bomb.
= = =
Fast forward. Hitler dies from Parkinsons by 1950 and Werner von Braun oversees the first human to Mars mission launched from equatorial Somolia in the 1970s.
Working title: "Black Mars"
If your entire culture and way of life were threatened with destruction at the hands of utterly foreign invaders how much force would be required for you to give up and accept the new masters?
Those who answer along the lines of God himself could not make me kneel may have a profound insight into the mindset not only of the Japanese leadership of the time but the Jihadi wackos we face today.
Indeed!
In Iraq we are fighting against testosterone more than we are fighting against Islamo-fascism.
-- Some experts estimate that, if D-Day had been delayed for only another 6-12 months, the Nazis would probably have had weapons in their hands which could have turned the tide of the war in their favour.
Perhaps and perhaps not. This point is controversial.
But anyway, the Soviets still would have been darn close to Berlin by the Summer of 1945 and without D-Day a few A-bombs would have killed maybe one or two hundred thousand Russian soldiers but even that would not have changed the final result.
No D-Day? Joe Stalin would have rolled all the way to the English Channel, a Nazi A-bomb or not.
Google Operation Bagration, which started on the Russian front within days of June 6, 1944. Wikipedia has a decent article.

My idea for a "what if" alt-history novel? Moved to the new fiction section.
Good thing the ol' subconscious knew something was up.
* * * Glad to hear you made it out unscathed.
As Josh said, "Yeah, that dream saved my ass. I might've woke up coughing but I really think that this place would've been totally burned down within a 5 minute timespan."
Our subconscious can be often be smarter than we are. But maybe get a battery backup smoke detector and a CO detector. My Mom bought all her adult children smoke detectors one Christmas about 15 years ago.
Speaking of dreams, when I was about 10 I needed a general anesthetic for some dental surgery. I was totally out.
To this day I vividly remember my dream about climbing a ladder inside a well, with gray clouds over the top. I was climbing and climbing and climbing until I reached the top. Stuck my head out of the well and I opened my eyes and instantly I was in the recovery room at the dentist's office..
Semi-buried greenhouses could receive sunlight supplements through use of inflatable mylar coated passive collectors spread around outside the facility and possibly light tubes, some of which have attained rather high transmission percentages.
Set up a few dozen inflatable mirrors focused on light tube collector plates and a substantial amount of sunlight can be gathered, far more than just what falls on the greenhouse "naturally"
Back on the old CivCult Mars forum we revisited this topic endlessly.
The sulfur light (they have some in the Smithsonian) is a solid state (hard to break) energy efficient full spectrum light for back up reliability.
Ad Astra, I believe Mike Griffin and Chris Shank will start spreading their plans next week. Griffin is scheduled to speak to an AIAA luncheon on August 31st and Chris Shank is speaking Saturday at the Mars Society convention.
These presentations may coincide with the release of significant mission architecture news since Griffin appears reasonably media savvy and wishes to include the space advocacy community in his outreach efforts. Also, Griffin owes Congress detailed answers to a number of questions and in sub-committee testimony, he promised those answers will be delivered during September.
The book should be a fun read, but we probably will know many of the hard facts before then.
= = =
At "Return to the Moon" I heard a funny anecdote about Chris Shank I posted somewhere else in a now buried thread. It seems that in late Winter 2005, in his role as a Congressional staffer, Chris Shank wrote an extremely detailed and technically astute request for information and submitted it to NASA.
Then, Mike Griffin hired him to work at NASA.
His first assignment? Answer that request for information he prepared.
True? I dunno. But I sure hope so, because its a funny story.
What causes the segregation?
Tribal hatred.
The question can be posed this way. "Did Saddam make Iraq or did Iraq make Saddam?"
Given the patchwork quilt of tribes, Saddam believed that only his heavy hand could keep Iraq together as one country. The Shia (such as those who murdered Vincent) would routinely rebel against Saddam and be brutally repressed. Sadr, the Shia firebrand who we deem as dangerous is the son of a cleric murdered by Saddam.
Before the 1920s, the Sunni/Baath (Saddam's tribe) were the henchmen used by the Turks to suppress the Shia and the Kurds. The Iraqi Shia have more than 100 years of animosity towards the Sunni.
The Sunni also hate the Shia as apostates. bin Laden hates the Iranians as much as he hates us in the West, maybe more - - think Catholic versus Protestant at teh time of Cromwell in England.
The Kurds have been steadily laying a foundation for an independent Kurdistan, which terrifies the Turks, Syrians and Iranians and Israel has started giving Kurdish militias support.
Within these three large divisions (Kurd Sunni & Shia) numerous sub splinters exist as well and alliances form and dissolve with great frequency.
= = =
Iran has a very powerful interest in assuring that a Shia dominated govenrment run Iraq. Not a Sunni, Shia Kurd coalition but a Shia dominated government.
The newly elected Iraqi President (remember the blue fingers?) is VERY friendly to Iran. If the elected President chooses to make Shia Iraq an ally of Iran what do we do?
Josh, what if the new Iraqi army is mostly Shia and Kurd?
That is the statistic we need to know before we can say whether an integrated Iraq is feasible. My reading suggests that the new Iraqi army is itself very, very heavily segregated between Shia, Kurd and a few Sunni, especially the officers.
