A mixed assortment of vehicles is unessesarry, we are better off building only the "big" kind of vehicle rather then spending money developing the "small" kind.
While I'm not going to agree with this unconditionally, I've got to admit that there's logic to it. Heavy lift launch vehicles are the most efficient for reaching orbit, and are arguably the best option for many applications. Diversity can wait until after we're out of the well.
Zubrin's little moon proposal needed a HLV, and a SDV is the HLV that NASA most desires. So, apparently, he decided to settle.
That's not heresy, and it's not an attempt to submarine manned moon missions. It's just...
... complacent capitulation! :?
All right, who is this guy, and what has he done with Robert Zubrin? :shock:
Hello, I'm looking to get a copy of the Discovery Channel show "Surviving Mars" about the Mars Arctic Research Station that aired several years ago. I've already checked with the Discovery Store, and they don't offer it (confirmed via email), and it's not scheduled for replay on TV anytime soon.
If anyone knows where I can get a copy, please let me know.
Thanks.
A quick review of books-in-print reveals they've never offered it.
If the Discovery Store won't help you, try the original producers, Resolute Films, at:

The may direct you back to the Discovery Channel, in which case your only option becomes looking for someone who recorded it using their VCR.
Well Tuvalu is an independent country now but with the same head of state as Britain. It is part of the commonwealth but so is Canada, Australia and since Commonwealth countries provide very dood basing for the USA not to mention those that are still British colonies. I doubt the USA objects to its Ascencion Island base or even the base on Diego Garcia.
Yeah, but Tuvalu is still part of the British commonwealth. I'm sure they could do it if they wanted. I wonder what they would take for Scotland? I'd offer Louisiana, but it's sinking just like Tuvalu... Texas maybe?
Tell us all why you have a right to a market share of resources.

According to the Gale Group's register of associations, the Mars Society's membership is now declining after growing roughly linearly between 1998 and 2003. Does this mean we only had support when people were afraid we weren't going to Mars? Or does it mean that I need to start paying my dues again so I'll actually show up on the next count?
Hmm...
Ah! Bob's plan gives up the dream HLV. Got it. 8)
Not a commonwealth more like a confederation of independent states. Probably go by the name of the New Anglian Confederation or something like that.
Sounds like a church. :? No, "Commonwealth" has worked before, it would work again. Canada aside, confederacies have a bad name here in the States, anyway.
There's technically a US Commonwealth already, consisting of the USA proper, Puerto Rico, Guam, and a host of other little islands. I could see us with a few additions, but I'm not sure Tuvalu's worth open warfare at this juncture. Perhaps the British could swap us something?
It would be interesting if some small pocket of Neanderthals or Homo Erectus survived to this day, further blurring the line between what we think of as man and ape.
You know, they're still looking for Ebu Gogo. That whole "Monkey Man" thing over in India is looking really suspicious, too.
I have seen a few people that have had the high forhead and very big bone structure that was associated with them.
I wasn't aware that you've seen me in public before, SpaceNut.
I don't believe this rises to the level of heresy.
Most of Zubrin's statement is just discussing the requirements to send a crew return vehicle (remember the ERV?) directly to the moon if it will be using a direct return to get back. Applying those limits to the CEV won't necessarily hamper a moon mission if 70% of its hardware arrives on another rocket. There's no renunciation of "Moon Direct" here, and, IMHO, nobody's flying to Mars with nothing but a CEV, anyway.
The blurb about finishing the ISS is chilling (typed by Bob's own hand *shudder*), but this course has to be considered. The International Space Station will not be safely at the bottom of the Pacific by the time work begins on a heavy lift vehicle. NASA will probably try to wed any new HLV to the ISS just out of general principles. We shouldn't just sit back and enjoy the ceremony, but we must be prepared for this eventuality.
That's not worth the trouble for leak control. Reaching up with a big pole and placing a reinforced patch over the hole will offer just as tight a seal.
Considering that the usual sources of coke here on Earth are coal and petrochemicals, I think that research could be very useful to the manufacture of steel on Mars.
It ties in with http://www.newmars.com/forums/viewtopic.php?t=3485]this thread and http://www.newmars.com/forums/viewtopic.php?t=280]this one in ways I'd never thought of. Put them together, and you've got steel!
A little australian genius could be just what Marsian metallurgy needs. 8)
China and Russia are not convinced that the world is going to be all warm and fuzzy from here on. Neither should we. We need to start watching them closely and we need to keep up our military capacity. We need to bulk up the military like so many have argued, but not just to fight some brown guys with a tendency to spontaneously detonate.
Hold on a moment, I've got a serious dilemma here:
How did the dream with Colonel Petrov end?
(What, like I'm going to argue with that quote?)
If it works out this way, we'll transcend the present Left and Right. Both will be reduced to irrelevance. I'll be having a goat roast, even the New Mars Lefties are invited.
I agree with 8.5 of the Green Party's "Ten Key Values", so I could get on board with the whole decentralization thing. Save me a haunch.
I'd need to have someone to blame, though...
"What will it take to fly in September?"

No ma'am, they make those tanks over in New Orleans. A poppet isn't just a kind of valve over there, you know. There's enough voodoo doctors with live chickens runnin' around that you ain't got to wait for a miracle...
Clark,
The comparisons between the Simplicity movement and a religious movement are abundant, but so are the comparisons between religion and the Mars Society. I am not convinced that this represents a new cult springing up around process flow management. (I'll consider myself warned, though. The Mars Society is starting to look really suspicious lately. )
From what I can tell about the Simplicity movement, it is indeed primarily a "western" (or "northern" or "first world", depending on which pop culture shorthand you prefer for affluent european/american industrially influenced) cultural phenomenon. Most of the earliest proponents lived in North America. I don't consider that much of an indictment - space travel started out under similar circumstances. At this point, any discussion of the Simplicity movement can't cover anything so magnanimous as "Humanity as a Whole." From what I can tell about the earliest groups (those represented by Elaine St. James, et. al), no founding member started with an income less than $50000/yr, so these groups were generally not started by poor people.
They claim to borrow heavily from the lifestyles of the poor, though after some review of their various philosophies I think "the thrifty" or even "the miserly" would be a better description than "the poor". That's not necessarily undesirable. They're advocating a methodology, not a vow of poverty.
Many of the recommendations of these groups center around reducing immediate expenditures. They suggest giving up cable TV, restaurant meals and various other luxuries to reduce expenditures. The really hard core members do things like sell their homes and either buy lower cost housing or move somewhere they can rent for the same cost as their prior mortgage payment (thus saving maintenance costs). Or they join group living arrangements to save money. Far from advocating hedonism, there is a distinct thread of asceticism in their teachings.
They don't typically advocate moving to log cabins in the woods, though. They claim there's far less effort required to live in a city. Average city jobs pay more per hour, more options are available, and commutes are less taxing when you live near your job. Most of the group living arrangements identifying themselves with the Simplicity movement are found in cities, not rural areas.
As for their whole take on reducing work at work:
Say we can do the same work in less time- well, sure, we as individuals might benefit if we could keep the remainder of time, but we have already traded a segment of time to our employer. That extra time belongs to them, and thus they demand more work.
I never said they fundamentally disagreed with that. In addition to recommending that you try to do the same work in less time, they also recommend that once you find a way to do this, you should negotiate with your boss to reduce your hours to a more appropriate figure. This reduces the potential for conflict over "stealing time", and keeps you out of destructive behaviors like milking jobs and soldiering. Failing that, you should go looking for a more suitable part-time job.
To expect otherwise is to achieve efficiency at the expense of productivity.
Near as I can tell, they don't care. Their focus is on the individual benefit, and let the employer worry about his end.
Hmmm... the whole thing just smacks of effort.
Now you’re getting it!
The simplicity movement isn’t just about trying to organize your stuff, or being able to do more things. It sprang up in recognition of an important fact: Even though we have more labor saving devices than our ancestors, we spend more time working.
True, the simplicity movement is full of labor saving recommendations, such as “Avoid social events you dread,” “Don’t answer the phone just because it’s ringing,” and “Stop doing 'busy work' at work.” But those are just recommendations. If you decline to “Stop making the bed” because clean linen turns you on, you can still proceed to simplify your life. The fundamental point of the simplicity movement is: Once you clear time for yourself, don’t turn around and cram something else into it! “Take a break!” is the motto you should live by, not “I need a break!”
There’s more to it than just lounging around and letting your house go to pot, though. The simplicity movement is best thought of as covert Taylorism.
Taylorism (“scientific management”, “industrial engineering”, etc.) has gotten such a bad rap from industrialists using it to squeeze productivity out of hapless employees that people forget Frederick Taylor originally envisioned it as a two-way system. Just as its methods can be used by your boss to maximize your productivity so that he can get you to do more in the same time, you can use its methods to maximize your productivity so that you get the same work done in less time. And the fundamental rule of workplace simplicity is, you take the rest. Never waste your extra time by giving it all back to your boss. The simplicity movement is not saying be lazy, or make yourself unavailable. It’s saying carve out break time for yourself and keep it, even if it means finding a new job that will allow you to do this.
And that’s just the time management advice. Wait until you look into the economics. 8)
I bet you still have to buy a book.
No, actually.
I'm sure they would recommend using the library, and be sure to ask for an extended due date, so you won't have to rush. 8)
Perhaps a purely religious track isn't the most productive course for a discussion of materialism.
Has anyone looked into the simplicity movement? It's inspired by the ideas of Elaine St. James and other authors promoting the virtues of material simplicity over modern mass market culture. Many of these groups are religious in character, but their common philosophies are primarily taken from economics and business management theory, not their differing religious backgrounds.
Heres]http://www.simpleliving.net/seedsofsimplicity/]Here's just one example - a group centered at Cornell.
Middle Easterners should be targeted for searches on city subways, two elected officials said, contending that police have been wasting time with random checks in efforts to prevent terrorism in the transit system.
It is a harsh truth that targetting those clearly of Middle Eastern descent would cripple nine out of ten potential terrorist plots today, at least in Britain and the States.
And a few years from now, when Al Qaeda simply switches to recruiting white guys from Iran, they can just walk in and the police will wave hello as they pass. Heck, if I were them, I would promote racial profiling as part of their long term strategy.
There has to be a better way.
Shaun, as a lawyer I help people start up new small businesses. Most fail.
The statistics are grim, like 70% of all new business start-ups fail. Maybe that's okay because trying is good and should be encouraged.
But if you have a family, to go naked without health insurance and start a business is pretty damn foolish. Unless your employer offers health insurance the rates border on unaffordable. Among my construction clients most have a wife who works full time at a really big company and therefore gets excellent group medical insurance.
And I know people who stay at their big company jobs (that they hate) instead of starting a new business because they cannot risk a spouse or child getting sick without insurance. Rather than promoting rugged individualism, this creates a nation of Dilberts, company man who are too timid to strike out on their own.
Hardly the mythical American dream.
I take issue with everything except the last two paragraphs, Bill.
According to the US Census Bureau, around 70% of new Amercan businesses survive at least five years. Starting a business is hard, but the claim that 70% (or 80%, or 95%, or whatever - it varies) fail in five years is an urban myth. Of those that do go out of business, sample polls suggest that only half "fail" according to the traditional economic definition - running out of money. The rest are bought out, retire, etc.
Having already been a card carrying member of that failed 30%, I'll never tell anyone that starting a new business is easy. However, the odds of success are better than even.
If both your "experience as a lawyer" and your own business records agree that 70% of your clients go out of business, you should consider getting out of bankruptcy law.
While I'll concede that going without health insurance for one's family is foolhardy, you imply that this is what it takes to start your own business. That is not correct. Business owners can get insurance (both group and private) just like business employees. My own wife gets a great insurance policy offered by our parish government, but that's not why she's working in the first place. The savings of a group plan compared to private insurance are nothing compared to the added income of a second job. Forget insurance: My girl's workin' for the money! (That and the fact that she seems to love public service. We'd miss that money if she joined the peace corps and got on CHAMPUS, though.
)
Then, there's the last two paragraphs. Spot on, I'm afraid. :cry: And it's so sad, because it does not have to be that way! Insurance is a great idea, it really is, but our present insurance system is making us dependent on our employers' good graces. And this popular fib about how the world is flat and ends just outside your boss's gate isn't helping much.
Now that I think about it, I could be convinced to support a lunar base rather than a manned mars mission...
If I were personally going.
srmeaney's plan doesn't seem to be materializing, though.
Dont]http://space.com/adastra/adastra_mars_050802.html]Don't ask "Why bother?" Ask "What can I do?"
... there is a chance that if we really want to get to Mars we have to come to the realization that we might have to do it ourselves. Privatization, in my opinion, would also be a stronger statement, as it would trancend nationality in our resolve to settle Mars.
You mean something like what was discussed in http://www.newmars.com/forums/viewtopic.php?t=2258]this thread? Or http://www.newmars.com/forums/viewtopic.php?t=37]this thread? Or http://www.newmars.com/forums/viewtopic … ight=]this one?
Or perhaps you're discussing the startup of private companies. Either way, I'm with you, Ben.
Every communications satellite in the sky had stopped talking to the Marvin. The global positioning system had provided a wildly erratic fix that had ended with a rejected result, then ended abruptly in the loss of every GPS signal nearly simultaneously. It’s tracking system, once a node in a vast integrated traffic control network that spanned the entire planet, had been completely cut off from its central server. The blimp’s computers vigilantly continued trying to monitor it’s surroundings using only its own meager resources, scanning with radar and searching the communications bands for uplinks and other useable radio signals. But the only broadcasts it intercepted were telemetry from satellites in inclined orbits overhead, mostly encrypted, and none equipped to respond to Marvin’s automated hails.
Ominously, even the few satellites Marvin had managed to locate were now disappearing, one by one as their orbits crossed the zenith. Vanishing, some with a final mysterious rustle of static, some fading inexplicably, others with the final desperate shriek of a distorted carrier. Then, silence.
Something very wrong was happening in the heavens.
“Where are the broadcasts?” Terry asked.
“I’ll keep monitoring the Polestat,” Brian told Terry. “Maybe they’ll follow the emergency tone with a broadcast.” He didn’t sound hopeful. Thus far none had been forthcoming, and it seemed the polar statite would soon be all there was left. Little more than a glorified weather satellite, it also performed one other critical function for the people of Mars. On a world with globe girdling sandstorms and a dozen other hazards, it was part of the planetary emergency broadcast system. Practically the only thing left in the sky, it was now broadcasting an attention tone once per minute. An automated message, stating the danger and giving instructions to those affected, should have sounded in the Marvin’s cabin, but there was only silence between alarms.
“Yeah, do that, Brian,” Terry told him. And hope it does, he thought. Otherwise, this could get hairy.
“Can we access the weather feed?” Bob asked, hanging at an angle from the plastic door frame to see over Will.
“What’s wrong with your tracking?” Will asked, pointing.
Ms. Reece, arms crossed, had claimed the other side of the doorway as her own, and stood in it as if to dare all comers. There was a line forming behind her.
“No, we are not getting the weather channel,” Terry growled angrily, getting him a glance from Brian and little else. He was losing his patience with these people. Every single one of them wanted to fly the ship himself, and not one of them seemed mentally capable of remaining in a seat belt. “We appear to be having a minor control problem. It can’t hurt us if we just stay put. We will inform you of any developments. Please, return to your seats.”
Just then, a gust of wind caught the Marvin and jerked it sideways. People shouted as they were thrown about the cabin. Will fell backward, taking Bob with him, and Ms Reece ended up with her back against the starboard window.
“Thank you,” Terry said absently as his passengers were briefly distracted. “Where the hell did that come from?” he asked Brian as he turned around to take the controls. The rogue gust had tossed the ship back and forth through a wide arc, dragging its landing gear through the soil in a long curved trench. Marvin’s propellers whirled to life as it sat on the ground, wresting the ship back from the wind.
“Oh my,” Stacie gasped. “Look at the dust move! That wind has be going at least a hundred fifty miles per hour out there.” Muttered comments of awe issued from a few other passengers.
Dumb Earther. “I’m sure it’s not going that fast,” Terry assured the passengers. “Sandstorms rarely reach sustained winds over –“
Brian pulled the bridge door half closed and leaned over. “We just hit two hundred knots, Terry,” he said softly. “We can’t fly in this; it’s coming in too fast, and it’s only getting faster. We’re going to have to drive back.”
Terry swore, and not under his breath. “Damn it, Brian! If we pull the rip cord out here and drive off, the envelope won’t be waiting for us when we come back. It’ll blow off and shred on the rocks. That’ll cost us hundreds of thousands!”
“Marvin won’t fly against this, Terry, and it sure won’t land at two hundred knots even if we could get to Olympus. We’ve got to cut loose and drive in.”
“Damn it, Brian!”
“There’s something else,” Brian told him. “I ran the tracking back over the last hour. You’re gonna want to see what happened while we were outside.” He started the replay. “A little over an hour ago, everything was completely normal. Then we started losing satellites, like this one,” he said, pointing to the screen. In the fast forwarded view of simulated airspace being played back by the Marvin’s computers, a little pixel that had been passing over their position slowly, inexorably veered from its orbit, ultimately turning onto a downward trajectory that took it plummeting into the atmosphere. “That’s where tracking lost its signal. It had to have burned up. Then there’s the ships.” Brian skipped ahead to the track of what was clearly a lander, hopping from Hellas to it’s listed destination at Olympus Station. But it never made it. The suborbital craft was dragged downward, falling onto the craggy plains north of the Marvin, a hundred kilometers short of Olympus. “Tracking says this one made it down, and these two. That’s the transport we saw go down in the ravine,” he said, pointing with a pained expression to a new dot on a long downward pitch. “They didn’t make it. That’s going to be a major crash site.” The display paused, and the screen filled with little grey boxes. “That’s where we lost the satellites. All we’ve got after that is our own radar.”
Brian paused a moment, then added, “Olympus isn’t receiving, and even if they were, they can’t fly in this. Everything that’s tried has been forced out of the sky. There isn’t going to be an air rescue. If any help is coming, it’s coming overland, which could take days this far out..”
“What the hell is it?” Terry asked. He was the sort who usually got angry rather than frightened, but shock was threatening to get the better of him.
“I don’t know,” Brian said, shaking his head. “But it’s got to be the worst disaster that’s ever happened on Mars, and as far as we know, we’re the only working vehicle on this end of it.”
“Well, then we’ve got to go help!” Will said valiantly, shoving the door back open after eavesdropping on the other side of it. “We may be their only chance of rescue!”
“Yes!” Ms. Reece agreed. “We must see what we can do. It is our duty to come to their aid.”
“Bull!” Terry roared. “It’s the duty of the marines and the emergency service to come to their aid. We are going to pull up stakes and head straight back to Olympus as fast as we can go! Standard operating procedure for saving our asses! I’m not taking this crazy bunch into the middle of a killer sandstorm to put my butt on the line for people who are probably already dead anyway. Now, for the last time, shut up and sit down, all of you!”
“No, I will not,” Ms. Reece informed him, refusing to move. “You heard him,” she said, pointing at Brian. “It will take days for rescue teams to get here if they can’t fly in. Anyone still alive at that crash site could be dead by then, and we are only ten kilometers away. If it was you out there in nothing but a crushed lander and a suit, would you want the only people close enough to help to turn and run home to mama?”
“That’s it,” Terry said angrily, unbuckling himself. “Get up and help me with this, Brian.”
Brian stayed put, looking at him. The only thing his copilot moved was an eyebrow. “We’re legally obligated to assist here, Terry,” he said.
Terry stared back for a moment, exasperated. Then he turned and grabbed Ms. Reece by the forearm. “I said stop this and sit down!” he shouted, pushing the little old lady down the aisle.
“I will not!” she shouted. Lacking the physical strength to resist, she was carried backward and shoved into a seat, but gamely tried to get up again as soon as her back hit the cover. Her fellow passengers scurried out of the way, trying to avoid the scuffle. An anguished look was on every face in the cabin, and Stacie was starting to weep.
Terry shoved the old woman back, focusing on the ringleader to show the rest who was boss. “We are not running off to some crash site!” he shouted. “You aren’t in charge here, and you aren’t big enough to make me! So shut up!”
“I will not!” she shouted, still struggling to free herself.
“Hah! What are you people going to do about it, lady?” he shouted at her.
…
