Robert or anyone.
Would it be possible to design a cold weather (i.e. Mars!) solid fuel rocket that mixed magnesium powder with dry ice (frozen CO2)? Build the thing inside a slightly pressurized freezer if the ambient Mars air temperature was too high.
Lace the magnesium powder with veins of frozen CO2 and igniter cords. Keep cold until launch and then launch from Mars surface to Mars orbit.

Off thread, but follows from Robert's post.

Costs for return orbiter to flight http://www.chron.com/cs/CDA/ssistory.mp … 86055]have soared says this report.
Ian, does this site help?
Russia wants into NATO and ESA...
And the right-wing of the GOP wants us out, right. . .
I envision an air launched Shkval torpedo, dropped by a Backfire or similiar fast aircraft standing off from the naval target.
http://www.deepangel.com/html/the_squal … quall.html
With their longer ranger, the Shkval II and newer variants could potentially be launched at a distance of over 60 miles, and home in on their target, with no countermeasures available. As such, a single nuclear equipped Shkval could take out a carrier battle group whilst sitting tens of miles away.
Alternative? Park a mini-sub armed with Shkval(s) in the mud in the straits of Hormuz (or near Yokohama harbor) and go 100% passive - - when the red team passive sensors hear a carrier battle group pass within 60 miles, launch the Shkval to explode a nuclear warhead 200 - 300 meters beneath the CV.
The air bubble thus created would have a chance of cracking the keel of the carrier.
= = =
PS - - Part of my worry is =IF= Russia and France ally. That is why the Bush policy of bashing Chirac can have a significant geo-political downside.
The Russian Navy is the primary user of the Shkval. A downgraded Shkval, the Shkval-E went to an international arms fairs in 1995, and both China, Iran and France have been known to have acquired limited numbers of Shkvals. The Russian press has claimed that the technology of the Shkval cannot be reverse-engineered and thus the Russian Navy is marketing the export variant aggressively.
Supersonic torpedos armed with a tactical nuclear warhead would render a Mobile Offshore Base more of a target than an asset, no?
My reading suggests the Russians are working with the French on such things.
And do you think China will just kinda take the prepacked payload faring with the TransHab module with the "please don't open and steal our technology or use for military purposes - US St. Dept" tape over the seams and put that on top of a Long March HLV?
If folks are this paranoid about a giant plastic balloon, God help the Pentagon if some American designs genuine ultra low cost Earth to LEO lift.
Bigelow's research into improved inflatable technology will allow him a powerful market position on all space habitats.
Lots of stuff I ranted about before I heard about Bigelow's plans are now coming true.
Plastic spacecraft - - boronated polyethylene - - is the wave of the future and Bigelow is sinking his fortune into learning how to do it. He holds the TransHab patents, so everyone else starts a few steps behind.
If Russia/China/ESA want to go to Mars, being able to buy a Bigelow TransHab derived vessel nearly off the shelf is a major step forward on affordability. Sned up the billionaire tourist wannabe on a dual purpose mission - - joyriding AND testing durable plastic space habitats.
So, you're a colonist on some Neu-Terra orbiting a distant oh, K-type star, and you're presented with a plate of the local munchables, Something looks vaguely like lettuce, except for being black, and the steak is oozing a strangely green-tinted fluid. :hm: Wonder how this stuff tastes...
I'm certainly no astrobiologist, but from what I've read it seems possible that animals could conceivably use something other than iron in their blood, copper or manganese have repeatedly come up as potentially workable. Plants could almost certainly use something other than chlorophyl. Sure, the scientific aspects of such alien life is fascinating, but from a settlement standpoint we'll eventually need to integrate the native life into our own food chain if at all possible. How might our Terran tastes intepret plants and animal matter with a significantly different chemistry, though not so much so as to be undigestable. Could get interesting, particularly if we have several distinct biospheres to work from.
Just throwing this out there, any thoughts?
Another question is whether any useful nutrition could be derived from it. After all, aren't some diet products based on chiral variations of common Terran protiens?
Twist a sugar molecule left instead of right and it passes through the human gut (sometimes quickly!) leaving no useful nutrition behind.
Alien biochemistry might make for some real interesting contacts. Not only can't we inter-breed maybe we can't even share a food supply.
Right now, Cobra, the faction stopping enactment of the vision is named "Sherwood Boehlert" and last I checked he is a Republican.
= = =
Space advocates need to be ready to play the two parties against each other and not let either party believe their support can be taken for granted.
= = =
Remember this. CEV is OSP with a fancy new name.
If Kerry wins, he will change the name (I like DSP for Dummy-crat space plane) but Kerry cannot re-certify orbiter without deafening protests and there is no political advantage to sticking with ISS as the only space objective.
One big difference might be whether we seek more (or less) Russian and European cooperation.
The Columbia accident forces everyone's hand. Democrats, Republicans, everyone. If Columbia had landed safely, that January 14th speech would not have happened.
Whether the orbiter can fly 25 missions between now and 2010 or 2012 is itself controversial. The idea that the orbiter can continue after that is simply absurd.
So, its either "Moon, Mars and Beyond" or we cancel the whole shebang and decide to stay home and watch Simpsons re-runs.
So, how can Kerry and the Democrats =OR= Bush and the Republicans possibly choose to abandon Moon, Mars and Beyond? IMHO, they cannot without being the party that ended America's space program.
= = =
Space advocates need to travel to Washington (like the past weekend) and quietly and subtly play the two parties off against each other.

MarsSociety email concerning Moon-Mars Blitz:
Mars Society and NSS Carry the Day at Moon-Mars Blitz July 14, 2004
For further information about the Mars Society, visit our website at http://www.marssociety.org]www.marssociety.org
The Moon-Mars Blitz has occurred and it has been successful.
The Blitz, which was the first important activity conducted by the new Space Exploration Alliance, occurred from July 11-13, and involved some 70 space activists visiting approximately 200 congressmen, senators, and congressional and Senatorial aides to convey to them a message of strong support for the new American space policy that refocuses the human spaceflight program on the goal of sending humans to the Moon, Mars and beyond. Of the activists present, about a third were drawn there by the Mars Society, a third by the National Space Society (NSS), while the remaining third comprised small delegations representing nearly all of the 20 space advocacy, industry, and professional organizations comprising the Space Exploration Alliance (SEA).
The Blitz proceeded as follows: On Sunday, July 11, the activists met at a hotel where they received training from SEA leaders on talking points and methods for conducting Capitol Hill meetings. Then the activists were divided up into 18 groups of 3 to 4 people, each of which was assigned to roughly 12 meetings over the following two days, with effort made to insure that wherever possible, a local constituent for the representative in question was included in the meeting. In all cases, the activists conveyed the message that NASA needs a goal, that the human exploration of the Moon and Mars is the right goal, that the entire American space community agrees on this, and that therefore the President's request for the Moon-Mars exploration initiative for Fiscal Year 2005 should be funded in full.
Reports coming back from the meetings indicate that the SEA activists were almost universally well received, and that the large majority of the responses from those met with were positive.
The Moon Mars Blitz was thus a brilliant success, but more action is needed. An in depth strategy planning meeting to map out further moves in support of the new human space exploration initiative will be held at the 7th International Mars Society Convention, Palmer House Hilton , Chicago, IL, August 19-22, 2004. Registration is now open online at http://www.marssociety.org]www.marssociety.org. Come to the convention and help lay out the political battle plan that will open the solar system.
Congratulations to the SEA for its successful debut, and especially the Mars Society and the NSS for doing so well in mobilizing their members to make the victory possible. Special thanks to Pat Czarnik, Mars Society Director of Outreach, who did the hard work of securing our exemplary turnout.
On the Chicago! On to Mars!

lol,
Cobra you beat me to it on the American comment, we really think alot alike.Errmmm. . .
Is that a good thing or a bad thing?
Why, of course it's good!
Join us in rightness! One of us, one of us, one of us.
Join the Magenta Agenda (Red plus Blue equals Magenta).
Because space policy is too important to leave to the politicians.
So, to answer your question, I say that the colonization of Mars should not be managed at all, but be done through the joyful chaos of human freedom.
I like that wording. Maybe a little dangerous, a little bloody at times, but the only way we'll really make progress.
I think that says it all. The pioneers of the Martian frontier will be the Americans of the future.
In more ways than one, if we get our act together. :;):
lol,
Cobra you beat me to it on the American comment, we really think alot alike.
Errmmm. . .
Is that a good thing or a bad thing?
What do you think aliens would think about how we look?
To be fair, clark, Zubrin also said this:
There remains only the question of science. Surely we should avail ourselves of the opportunity to study native Martian life before we terraform the place.
We surely will. Terraforming Mars will be a long term project, and should native Martian microbes exist, there will be ample opportunity to study it before terraforming takes place. There will also be opportunity to study how it adapts to warmer, wetter conditions and the presence of terrestrial microbes after terraforming takes place.
Furthermore, if Mars actually is terraformed, there will be much more people on Mars to study every aspect of Mars, including both its native and immigrant life. So in fact, our knowledge of Martian biota will be increased by terraforming, not decreased.
The politics of Zubrin were interesting to observe this weekend.
Some of the leaders of other space -advocacy organizations were not subtle in their disdain for Zubrin, however, of the 60 or so volunteers, at least 40% - 45% (maybe close to 50%) were there because of Zubrin.
Its kinda hard to dis-respect Zubrin when he delivered the people and I tried to be up-front that I was there because the Mars Society asked me to be there. :;):
The "Mars or Bust" pin helped. . .
= = =
Anyway, many kudos to George Whitesides executive director of the National Space Society. George is a great guy IMHO and was fairly skillful (again IMHO) at balancing his agreement with Zubrin on many points with the need to be diplomatic.
And many experienced space advocate types told me they were impressed by Zubrin's recognition of the need for diplomacy.
= = =
George Whitesides said one cool thing in particular during our training day. He said that everyone there should join every group:
MarsSociety
NSS
Planetary Society
and all the others in the Alliance.
"Come on guys" George said, "Just join all the groups!"
Ya know, maybe I've been too hard on Zubrin... :laugh:
clark, you just need to be. . .
HEAP - - NOH - - TIZED!
Once you see the light you will understand.
I'd rather celebrate something like the 50,000th post, which should happen in a few weeks time. Maybe we should run a little competition or something?
At the recent Moon-Mars Blitz I personaly recruited about 9 or 10 people to start visiting NewMars. Lets eee who actually shows up.
After I got to Washington DC I was disappointed I had not printed up some NewMars cards to pass out.
What about making palm cards (3.65x8.5 inches or 1/3 of an 8.5x11 sheet of card stock) to promote newmars.com and distribute at the August Mars Society convention and elsewhere?
John Kerry will announce a space vision.
Soon.
I am posting from a VERY slow, expensive hotel connection.
Anyway, today was waaay cool. We met with 3 House staffers and 3 Senate staffers.
Everyone seemed supportive but there was a real difference of opinion about whether any NASA legislation would get passed before the election. There will most likely be NO budget before the election, too partisan.
A bill to deal solely with NASA is being pushed by Tom Delay but Sherwood Boehlert may be blocking it. The AIAA has a luncheon tomorrow where the two lead speakers are Delay and Boehlert. Cool.
= = =
Then, just after lunch myself and two other Blitzers are assigned to visit a staffer for who?
Senator John Kerry.
Extra waaay cool. This needs to be bi-partisan and I get to go as close to the top (A junior assistant Kelly girl staffer) as a no-body like me can ever hope to go.
Wish me luck and light some candles.
Lots more once I return home to high speed flat monthly fee cable modem bandwidth!
Today was all training. Very very interesting.
Tomorrow our teams (there are 4 in my team) have appointments to visit the staff of 3 US Representatives (Congresspeople) in the morning and the staff of 3 Senators in the afternoon.
Way cool stuff.
I have been trying to spread the word about NewMars being a happening online space forum. One guy in the same team as me is coming to Chicago in August and promised to visit the forum.
= = =
The politics of the Space Exploration Alliance is very interesting as well. 21 space advocacy groups have gotten together for the Moon-Mars Blitz and one of our key talking points is that we can't agree on anything EXCEPT we all strongly support FULL FUNDING in FY ' 05 despite all of our other differences.
Zubrin and some of the other people probably could not agree what color the sky is, but they agree on full funding for next years NASA budget. Hopefully that will count for something.
= = =
A rumor I cannot give a source for. John Kerry will announce a major space policy position in the near future. Source? Eavesdropping in a tavern. ;-)
The SEA is considering doing this again in February 2005 after the election. If they do, you all should come.
I have not met any official people yet, but its already way cool.
Adios - hotel internet access is $$$$
???
I am here just outside Washinton DC to help lobby with the Mars Society and the NSS

Wooow this is getting down right psychodelic, I can feel the colors...
