I guess this is a bit of a digression from the topic, but I just wanted to express my support for a space elevator, too!
I've noticed Phobos keeps coming back to the elevator in his posts, and I think his enthusiasm for it is very well founded.
If we can erect a half dozen of these things at intervals around the equator, all the other discussions of heavy-lift vehicles and riding to Mars in small dangerous 'tuna cans' will be moot.
The difference it will make to humanity's spacefaring capability will be enormous.
I think maybe we should just drop everything else and make a concerted global push to get the first 'beanstalk' up there as soon as possible!
A sad day for Russia indeed.
It reminds us how dangerous rockets are, doesn't it? And puts into perspective how infrequently a Russian rocket fails these days - they're so reliable that this event comes as a shock.
My condolences to the distraught parents who have lost a son.
Ha Ha Ha !!!
Actually, Phobos, I heard that musical instruments tend to degrade rather badly in a space environment.
Apparently they just break in half for no obvious reason!
Hey, turbo!
I think Earthfirst is only kidding around ( ... I hope! ).
I had trouble interpreting what he said, though. Who was it, speaking of America and Britain, who described them as two peoples divided by a common language?!!

I lived in London for 16 years. One year we had a summer - the other years, a watery spring just blended into a chilly autumn and straight back into winter again!
The sun came out a few times while I was there, but in general, everything was grey almost all the time.
Brits would LOVE a pink sky!! At least it's some kind of actual colour!
I'd take my wife, 'cos she's cool !
And I think it would be great to have Chris McKay along to explain points of interest and discuss future terraforming.
And, if by some magic I could beat the Reaper, I'd absolutely love to have Carl Sagan come with us. Nobody would appreciate the trip more than he!
And I couldn't leave out Pete Conrad, commander of Apollo 12 and my favourite astronaut of all time. Such a wonderful sense of humour and what a supremely capable pilot - and definitely someone you would want around if the chips were down!
Thanks, RobS !
At the same site you linked, it also answers my question from a different angle.
Apparently, L4 and L5 are only theoretically stable equilibrium points. There are sufficient perturbations in the Earth/Sun/Moon system that station-keeping is required at L4 and L5 too!
So we might as well stick with L1 for the advantages you listed, since we'll have to use fuel for station-keeping at any of the Lagrange points anyway!
Much obliged for your prompt response!
Why the fascination with Earth-Moon L1?
According to what I've read, L1, L2, and L3 are 'meta-stable' points. In other words, they are points of unstable equilibrium, and a station placed at any of them will require 'station-keeping' fuel because of a tendency to drift from the desired position at the slightest provocation.
Why not put a station at L4, which is like a shallow gravity well? A station at L4, even if gently pushed away from its position, will tend to return to the vicinity of L4 all by itself.
It may be marginally more costly to get to L4, but at least we wouldn't need any fuel to stay there.

Thanks for coming back to me on this, Josh!
Interesting that you've mentioned Gaussian blur on both the official image and the so-called 'real' image.
I was labouring under the impression that Laney had Gaussian blurred the image he downloaded on July 25th, but that a completely untouched 'real' image was recovered from somewhere - and that this is the one TEM is presenting now on its site as the 'real' image.
If, as you say (and I do NOT suggest I doubt you for one moment), there is Gaussian blur on BOTH images, official and 'real', then I take it that will complicate things? If so, does it then become impossible to determine who's pulling a fast one and who isn't?
You can see from my questions that you'll have to explain what you do, step by step, because I'm unfamiliar with the processes you describe and even the terminology you use. I apologise profusely for my ignorance, which must be as irritating to you as it is frustrating to me!

CALLING JOSH CRYER!
Hey, Josh! ... Are you out there anywhere?
The Enterprise Mission is back on deck at a temporary server (or something) and its files are now accessible again.
As you will remember, we were all hanging out for the so-called 'real' IR image of cydonia - the one Laney alleges he downloaded on July 25th, at the laboured behest of Noel Gorelick at ASU.
I think you said something to the effect that as and when the raw TIF became available, you would try to find time to analyse it and tell us what those artificial looking shapes really are.
If you've been following this thread, you will have seen that Tripp McCann has already given his verdict. He maintains that grossly inappropriate processing of the data has given rise to what looks like right-angled structures in the image. In other words, they are easily explained and easily duplicated introduced artifacts.
For my sake, and the sake of other interested parties, would you please take a look at the data and provide us with a 'second opinion' about it?
If you corroborate Tripp's evaluation, I think it must very severely compromise the whole TEM position, probably beyond redemption.
Waddyasay, Josh? Can you spare the time? :0
Thanks Adrian!!
Thanks for trying Phobos!
But I'm a bit concerned about you putting on your metal helmet....
PUTTING IT ON !!! .... GOOD GOD, MAN !! ... WHATEVER POSSESSED YOU TO TAKE IT OFF IN THE FIRST PLACE ?!!!
I took mine off once. And that was when I woke up face down in the dirt, just outside the perimeter fence of Area 51, with the strange red marks on my forehead and the bar-code behind my left ear .... and the headaches ... Oh God, the awful headaches ... !!!

Hi Adrian!
Just to alert you to what may be a glitch in the Face on Mars forum.
After my most recent post there, I'm pretty sure there was a response from MarkS and Nirgal82, and then a response from Tripp.
I planned to come back and reply to their comments when time allowed, but have found since that only MarkS's post remains. Nirgal82's and Tripp's posts could be on page 7 but page 7 doesn't want to open.
Even Cindy's clever trick of going into "reply mode" in order to access the recalcitrant page, fails to work in this case!!
If you get time, could you please look into this?
Many thanks in anticipation!
Hi Austin!
Your mention of the KSR-type ice habitat as a possibility for polar expeditions on Mars might be workable.
I read somewhere lately that layering in the polar ice indicated an age in the hundreds of thousands of years at the north pole (if memory serves), and maybe up to five million years at the south pole!
Don't quote me on the actual figures here, in case I'm off base a little.
Anyway, the point is that man-made ice caves would probably be stable over long periods. And, as you said, would be relatively easy to create and would provide their own very effective insulation.
I have reservations, though, about the necessity or desirability of landing at the poles, for the reasons you mentioned. Considering it now looks as though water will be easier to find at various places all over the planet than we once thought, do we really need the aggravation of high winds and searing cold?
Mind you, the suggestions made so far about the MGS camera having possibly snapped shots of 'things' growing on Mars' surface, are at least predominantly (if not exclusively) related to polar regions. But then, I have trouble with these suggestions for exactly the same reasons again: Why would vegetation on a freezing planet deliberately choose the coldest areas to live in?!!
Isidis Planitia's southern extremes recently featured on a list of places where it has been found to be theoretically possible for liquid water to persist at the surface. Nobody said there was actually any water there, but that liquid water is possible for certain portions of the Martian year because of the ambient pressures and temperatures.
That would be one place I'd be interested in exploring. Especially since it quite probably formed an inlet of the Oceanus Borealis in Mars' balmier youth, and former shorelines, and maybe even fossils, might be found.
Besides, it's almost at the equator and I could wear short pants and a T-shirt under my pressure suit!!
Tripp wrote this on Oct. 12th:-
Nirgal
You seem to be "stuck" on this. I wouldn't be so hasty to award yourself so much wisdom in this matter. The "rain cloud" was only a small part of a much larger presentation - thabe being the presence of fluid "water" bodies on Mars surface; the presence of these fluid bodies are the subject of the presentation which you reference.The "cumulus cloud" was only a hook and a tenuous conclusion to the matter.
Tripp, I find this statement of yours quite extraordinary!
You have based your whole argument for the existence of intelligent industrial activity in the Mariner Valley on your self-proclaimed expertise in the interpretation of satellite images. Whenever I have disagreed with your interpretation of an image, you have been very quick to blame my (admitted) lack of experience in differentiating between mundane geological surface features and what you describe as intelligent artifacts.
Now, when it turns out that you are capable of confusing an entire valley, Hebes Chasma, with a raincloud, you blithely dismiss that part of your presentation as "only a hook"! This is astonishing!
Here is an excerpt from near the end of your "Water World" presentation:-
This image is from MSSS image AB1-08503 and shows a clearly evident cumulus cloud with PRECIPITATION streaming down beneath it!!! Not only are there fluid water bodies on Mars and evidence of the long frozen surface thawing out even at non-equatorial latitudes, but Mars also has *RAIN*!!! It is highly unlikely that this cloud is streaming down Clathrate. While Mars must certainly have a unique Geology and environment, this precipitation seems in all likelihood to be WATER and that Mars has a developed ecosystem!
I believe a 'hook', in the way you are attempting to use it, is a literary device designed to capture the attention of your audience, rather like a 'catchy' heading for a newspaper article. But such a 'hook', while perhaps exaggerated for effect, must still bear a recognisable resemblance to the truth. Otherwise it is no longer a 'hook', but a fabrication.
What you have stated in the above quote speaks for itself. It is plainly obvious that you have either mistaken Hebes Chasma for a cloud raining water, or you have fabricated a complete fantasy in an attempt to add weight to your argument for surface water on Mars.
If it's the latter, a comment you made in your last post here becomes particularly ironic:-
Hoagland is a SHOWMAN ... a modern day "P.T.Barnum". Science is really irrelevant to him unless he wants to give his presentations some veil of credibility.
If it's the former, then maybe it's time to enact the code of honour you laid claim to when you said to Nirgal82 (in no uncertain terms):-
There is one difference between Laney and myself beyond qualifications, intellect, ability and experience: my own presentations and theses are not static nor mired in the concrete of arrogance and ignorance and I am more than willing to admit when I have been mistaken.
I am also taken aback by your aggressive response to Nirgal82's attempt to point out your 'raincloud' discrepancy. You accuse him of getting "extremelly off topic", for one thing, and then accuse him of having his own agenda of "unbridled, blind support for Enterprisemission", for another.
Admittedly the discussion of rainclouds on Mars should probably be in the "Water On Mars" forum or the "Candor Chasma .. " forum, but since all of this is relevant to the "Intelligent Alien Life" subject in general, I think that objection is rather lame.
And Nirgal82 has stated that he is no supporter of TEM. In fact, I don't recall him ever having said anything to indicate a blind uncritical devotion to Richard Hoagland. That unprovoked attack by you appears to have come about simply because Nirgal82 had the temerity to ask you the same question twice. A question, it seems in retrospect, you were hoping would go away!
Speaking of questions that just won't go away! ... I'm STILL curious to hear of any of your fellow geologists who share your belief that intelligent industrial activity is going on in the Mariner Valley.
And I'd STILL like to know what the NASA employees at United Space Alliances, who asked for your opinion about the pictures of Mariner Valley, thought when they heard your report. Do they also share your excitement? And, if they do, can we expect an announcement from NASA any time soon?
I fear that unless you can give an adequate response to all of the above points and questions, my already severely shaken confidence in your veracity and credibility will be totally undermined.
Harsh words, to be sure. But no harsher than some that you have used toward others at this website.
:angry:
Thankyou, Tripp!
This is just the sort of thing I've been looking forward to hearing .... opinions by people skilled in image processing.
In view of the obvious frustration (and what I perceive to be almost righteous anger! ) in your tone, no doubt in large part caused by the admitted ignorance of your audience (me), I'm reluctant to confess I didn't understand all of what you said.
But I did get the general idea and I understand you are trying to tell me that I, and thousands like me, have been misled. As I have always been careful to make clear, someone in my position is easily fooled and is obliged to rely on those with a proper understanding of what is undeniably a specialised field.
I'm now looking forward to hearing from Josh Cryer, who is also, I believe, skilled in this kind of thing. No doubt he will corroborate what you have said, namely that the apparent structures below the surface of Cydonia are artifacts of totally inappropriate processing of the ASU image, performed by an incompetent Laney and exacerbated and endorsed by an unscrupulous Hoagland.
If this is found to be the case by everyone with the training to analyse such images, it must surely be a fatal blow to the reputation of The Enterprise Mission in general, and Richard Hoagland in particular.
It should prove fascinating to see how the TEM team tries to wriggle out of it, if it comes down to that!!
Incidentally, if you have time, I am still interested to hear of any other geologists who agree with your assessment that some of the Mariner Valley surface features constitute indisputable proof of intelligent activity there.
And also a question: You have remarked that you were approached by an employee of United Space Alliances (a subsidiary of NASA), because of your expertise in these matters, to analyse the Mariner Valley images. The point being, I think, to emphasise that you didn't set out on your own initiative to find evidence of artificiality on Mars, though the reason for the request apparently related to what you described as "mildly specific reportings of extraordinary evidences on Mars". Have you reported your findings to the appropriate NASA personnel and, if so, what was their reaction?
I still think an ESA/Russia alliance would be the quickest way to Mars.
Russia lacks cash, but has the booster technology and long-term space survival experience. The ESA has the cash and the computer expertise etc.
Let them go into direct competition against the U.S. and see what happens!
You bet!!
P.S. Welcome aboard, Quiet Storm.
Hi Bill!
I like what you're proposing. There's no substitute for good advertising because many people don't know what they want until somebody else persuades them they want it!
Stating the obvious, I know, but most of so-called 'consumer demand' is simply the result of the influence of advertising. How do you know you really NEED a more up-to-date cellphone until someone shows you what you're missing?!
How do unimaginitive people (that's most of us! ) know they want a thriving human colony, exploring and settling Mars, unless we show them the vision?
The First Steps angle is a stroke of genius, Bill! There are few things more evocative of hope for the future of humanity than a beautiful little child learning to walk.
And the message that a few LESS dollars spent on new ways to knock things down, and a few MORE dollars spent on building up a future for mankind in space, would mesh beautifully with images of that first 'native' Martian!
I think it's just great!!
Hi again, Josh and Tripp!
Just to remind you that The Enterprise Mission has finally released the unaltered, supposedly 'real' IR image of Cydonia, which they downloaded on July 25th.
Isn't this what you were waiting for in order to prove Hoagland and Laney are liars and crooks?
...... Hold the phone!
I've just realised the TEM website seems to be uncontactable. I guess that's why you guys haven't been analysing the IR image data for the tell-tale signs of tampering.

Josh, Oct 10, 2002:-
The only reason I invoke the moon in a discussion about intelligent alien life, is for one reason: The moon keeps Earth's core molten, and the Earth's molten core is what creates our magnetic field.
It's that simple.
I think I know what you mean about the Moon keeping Earth's core molten. You're invoking the tidal effect which you're suggesting is flexing Earth's structure and generating the heat necessary to keep the core liquid. Am I right?
If this is the case, I'm not sure you're correct.
In all the stuff I've read about Earth's internal heat, I don't remember tidal flexing being considered a major contributor. Naturally, tidal flexing must have some effect, but my impression is that it's very small in comparison to the accepted source of most of the heat, radioactive decay.
Of course, I could easily be missing something here. And I'm ready to be proven wrong.
Another possible 'fly in the ointment' is the recently postulated hypothesis that planets commonly have cores of uranium undergoing fission. The originator of this hypothesis, J. Marvin Herndon, maintains that Earth started with a ball of uranium 8 miles wide, and now has a ball 5 miles wide. He has theorised that ongoing fission in such a core would be sufficient to explain all the volcanism over the past 4.5 billion years, and can even account for the global magnetic field.
To further complicate the issue, we have the planet Mercury. Mercury has a very respectable internally-generated magnetic field.
Current theory, as you indicated, cites a molten core in a RAPIDLY ROTATING planetary body as the source of a global field. Mercury is a very small planet and its heat of formation must have long ago dissipated. The conventional radioactive decay model for internal heat production, in a planet of such small volume, predicts that that source of heat must also be largely exhausted. In addition, Mercury has no moon.
Thus every model for internal heat production, including the tidal model (but excluding the uranium core model), fails to endow Mercury with a molten core.
And, as we all know, Mercury rotates very slowly, thus driving one more nail into the coffin of the conventional hypothesis for global magnetic field production! According to our present understanding of planetary magnetic fields, Mercury shouldn't have one. But it does!!
All I'm saying here Josh, (apart from touting Herndon's new hypothesis of planetary reactor cores, which I think deserves further serious consideration) is that in the current confusion about planetary magnetic fields, it's a brave man or woman who dogmatically commits him/herself to a particular viewpoint.
Thanks for the compliment, Cindy!
And thanks for the very interesting history lesson about the origins of the Yuletide celebration. Fascinating stuff!
The Church authorities established the celebration of Christ's birth close to the Winter Solstice, in order to encourage pagan converts.
This tends to support my contention that there was, in fact, quite a degree of 'fudging' in the establishment of sacred dates.
If these holy dates were established by humans and not actually by God Herself, then surely we don't need to be quite so particular about how we translate them into a new Martian calendar.
I think most of the comments I've read are supportive of 'my' Martian calendar, unless I'm misinterpreting them. The weeks would still be 7 days long, Monday to Sunday, northern spring would still be in March, April, May, and would correspond to a lengthening of the days just like on Earth, and Christmas would be towards the end of December, during the northern winter.
Former Australians, who would naturally tend to settle in the southern hemisphere(! ), would still celebrate their Christmases during high summer, just like home!!
The only real difference would be the strangeness of having so many days in each month, but we'd soon get used to that.
In the event that changing the length of a second would be problematic for computers (though I don't see why we couldn't overcome such difficulties), would it be unrealistic to go back to KSR's 39 minute 'dead-spot' in the middle of the night?
Yeh, you guessed it .... I'm still trying to get that little bit of extra shut-eye!!
My God, what a question to ask at New Mars!!
I can already hear our resident politicians rummaging in their closets for their soap boxes!
If they can extricate themselves from the razor fights going on in other Topics, they'll be into this one like rats up a drainpipe!
P.S. Just kidding around .... no offence intended!
About the only thing more dangerous to argue over than politics, is religion. And, in the end, whatever you say will probably have no effect anyway because people form their own opinions in accordance with their own needs.
I subscribe to no organised religion myself. But, for reasons I cannot logically justify, I believe in 'God' - for want of a better word. Perhaps it helps me make sense of an otherwise big, lonely, and impersonal universe. So I guess its a contrivance of my own mind to 'help me through the night' and to explain how it is that people I've loved, who have died, can just disappear. I find it very difficult to comprehend that a vibrant personality, full of hopes and joys, fears and aspirations, someone intelligent, reflective, and affectionate, can just cease to exist.
So I factor in the notion that somehow, after death, we go on. How, or in what form, I don't really have a clue. But it helps me to think this way. I suppose it's a bit like Einstein's cosmological constant, which he conjured out of nothing and incorporated into his equations to explain the 'static universe', thought to exist at the time. 'God' is my cosmological constant - enabling me to balance my equations!!
But organised religions frustrate me very much. They're nearly all based on the here and now, though they purport to be 'forever'. Everything happened just lately: Yahweh appeared about 3000 years ago, Christ about 2000, and Muhammad about 1500 years ago.
My picture of the universe is big .... VERY big! And my conception of time is mind-numbing. I'm very aware that everything in human history has taken place on a speck of dust, on the outskirts of a run-of-the-mill galaxy, in a universe so vast we can't even find its boundaries. I'm very aware that everything in recorded human history has taken place in the last 0.00015% of Earth's modest span of existence (4.5 billion years.)
To me, it seems incomprehensible that God would specify a special day to be kept holy. What length of day? A day from Earth's past when our planet rotated once every 8 hours instead of every 24? Or one from the future, perhaps, when a day will be 28 hours long? Of what significance is a 'day' to an omnipotent eternal being, presiding as She does over days of different lengths on Earth and on different planets in different galaxies all over the cosmos?
Why should the Son of God ignore the Sumerian, Minoan, Babylonian, and Egyptian civilisations for nearly 5000 years, allowing them to live as 'heathen idol-worshippers', before finally making an appearance during the Roman period? Out of at least 35,000 years of anatomically-modern human existence, what was so special about that moment, 2000 years ago? As soon as Cro-Magnon man appeared, why didn't Jesus?
And if dates and days are so important that AJ wants to lynch Byron over them, why is Christmas day on December 25th and why is this the year 2002? There is apparently very strong evidence that Jesus was born in March of 4 BC!!
I'm told that Muslims set their spiritual calendars by the phases of the Moon. Are their clerics aware that the orbit of the Moon is enlarging and that the lunar month is lengthening? Is there any allowance or instruction for this eventuality in the Koran? I'd be very surprised if there were.
There is a meteorite in a building in Mecca which is venerated by Muslims. Why this particular meteorite out of the trillions of tons of meteorites which have fallen on our planet over the eons? Do the clerics understand that there is a finite chance the next 'stone from heaven' might demolish Mecca altogether, or maybe take out half the Arabian Peninsula? And what mention is there of this in the Koran?
And looking briefly at Judaism in the context of calendars, just so our Jewish colleagues won't feel left out of my reckless diatribe(! ), how do they know what day to celebrate the Passover? I'd be amazed if anyone really has a clue what date the Angel of Death chose to slaughter the first-born sons of Egypt.
And if Christianity depends on the predictions of the prophets of the Old Testament that a Messiah would come, how is it Jews have their Sabbath on Saturday and Christians on Sunday? The very word, Sabbath, is hebrew, isn't it? If Christians have inherited it directly from Judaism, why doesn't it bother them that somehow their holy day has 'slipped' back by a whole 24 hours?!
I have said all this, not to belittle the beliefs of so many of the world's people (though I admit it's hard to look at what I've said and NOT think that was my intention), but to explain my deep-seated inability to understand the conventions of three of the world's largest religions.
In the light of our enormously expanded knowledge of the universe we inhabit, the rules and regulations of these competing faiths start to look extremely parochial, at least to me.
The fact that there are various religions, with various calendars of sacred days, might actually be a good reason to deliberately ensure that any new Martian calendar is as blandly secular as possible. If it looks entirely secular, there can at least be no insinuation by one group or another of any bias against them.
And planets and their orbits are messy things. If God had wanted us to keep time so precisely, why couldn't He have made Earth's year exactly equal to, say, 360 days? Why couldn't the Moon have been persuaded to revolve about Earth exactly once every 30 days? And why not have them constant in their paths over all eternity, never slowing or changing their orbits?
Mars is a different world for which we have been left no software by God. And I think She would be disappointed in us if we didn't use our initiative and start from scratch with a secular calendar.
Let the Mullahs and the Priests and the Rabbis sit down and create a new religious observance timetable based on the orbital characteristics of our new world.
Surely, if it's that important, God will send us all another prophet with updated instructions for use on Mars.
P.S. This may be the biggest can of worms I've ever opened
on New Mars! I just hope it's received as it was
intended, as an attempt at a reasoned argument, rather
than any kind of attack.

An interesting link. Thanks Scott!
I noticed from the applet that it's very near the northern hemisphere summer solstice.
Weren't we waiting for more information about the distribution of water ice in the top metre or so of regolith in the northern hemisphere? And weren't we supposed to get it as soon as the CO2 'hood' lifted at the end of winter?
We're approaching the height of summer now, so where are the pictures of shallow sub-surface water ice we were promised?
Call me impetuous if you like, but I'm getting impatient!!
Anybody else getting antsy too?!
