I see also a nice side-effect in the press conference by NASA - some advertizing, always necessary to get the budgets passed. Remember - the announcement of the supposed fossil remnants in ALH84001, even by president Clinton - when did it take place? And when started the great Martian renaissance with all these incredible successful orbiters and rovers? And if you keep in mind, that sample-return-mission projected, if it will be realized, will be after the ISS and the space shuttle missions, the most expensive mission, the most costly planetary space-probe ever. Hopefully it will be done. And until then, we have to take potluck with the Martian meteorites we have already. hi Greg & Greg, could you please reconcile your differences off-list? Greg H. - I guess Greg C. simply didn't get the joke, because he isn't aware of the funny story of Haag, Zagami and ALH84001. And Greg C. I know that you sometimes support the notion, that we're all in meteorites only for the money. Though the meteorite prices are not endangered by new scientific recoveries. Much more they are endangered, because still some meteoricists and some clerks haven't recognized yet the direct correlation of find rates/availability of meteorites and the legal situation in the countries, they were and shall be found. You can observe already now the step-back and the regress in newly found material due to always new restrictions. Check the bulletins, what for a decline we have the very last 3 years in newly recovered unpaired planetaries. And regarding especially the Martians, I'm not sure how long you're in meteorites, but they already doubled, tripled, quadrupled in price during the last 4 years, because of that. And sooner or later, the collectors, hunters and dealers won't know anymore, how they still should supply the universities and museums further, with affordable, but rare and scientifically significant new materials. And really the least university institutes are in such a likewise comfortable financial situation like e.g. the Smithsonian or London - but nevertheless are urgently wanting to work on such materials. And we all agree, the more scientists have the opportunity to do their research on a meteorite - the better. So Greg C. - you have to appeal with your worries not to Jim or Greg H., but to such people like Dr.Bevan, the successor of al Kathiri, Dr.Chennaoui, Dr.Zuccolotto, Dr.Planche, (or in your country, those who initiated these new BLM-land restrictions) and others, who seem to actively support the ban of private involvement and with that the ban of new meteoritic recoveries.. ..and thus tossing not only the national meteorite research of their countries into a crisis, but global meteoritics too. Thus, in the end they are restricting the freedom of research. They urgently need some enlightenment about that, what they're doing and the consequences, which they are not able to see. I really hope, that this topic will be on the agenda at the next MetSoc meeting in Perth. Because today we have already very often the situation, that the important new recoveries of special meteorites are gladly welcome by all meteorite researchers, but on the other hand and in the same breath some scientists, not so seldom even some, who work on these very meteorites or use the results of the work on these meteorites done by colleagues, claim these very finds to be products of criminal activities and call the finders and those persons involved to bring the stones into the labs and institutional collections criminals. If we don't manage to resolve this pervert schizophrenia - and that immediately - then the meteorite research in that extent and quality, we were used to the last two decades - won't have any future. And Greg C., it is easy to forecast, that absolutely independently from whether E.T.'s car key of his spacecraft will be found in a Martian meteorite or not, that in 5 years we'll have 1000% surcharges on the prices we had the last decade, and not only on Martians but on quite all meteorites - and even more precarious, we won't then have anymore that variety of those new meteorites, which are exceptional and important for meteorite science, if we don't stop and partially reverse that trend. Huh Greg C., simple & very little example from yesterday, take that EL4 we're blowing out as our X-mas gratification for the collectors, 10 bucks a gram, still very nice chondrules - in the coming years you simply can forget such a price and such a stone at all. Antarctica isn't really an alternative - in 34 years only 200grams found of such. And else 6 finds from the hot deserts, mainly as a result of the enormous work, the private sector had done. Historically seen - you know it, the two DaGs cost minimum 15 times more, or if you go to the ELs in general - it's not so hefty weathered like the classics Happy Canyon, Yilmia or that stone, with which everything began a decade ago, NWA 002 and what for prices you have to pay for them, you know too. (Sooo, and to turn back to the title line, to crimp more advertizing in that posting, cause we're all in only for the mammon and finally to calm your fears Greg C. about the Martian prices to come, we'll distribute after the little EL4 main mass will have gone, the very last two slices of 4925, quite the wildest and most colorful shergottite of all, that with the pseudo-orangettes - but not here on the list - and that at the prices we had years ago). Martian greetings!

I know they're looking for water, but why? Could it be because 70 to 90% of a living organism is water? Water is the prime ingredient and habitat for life. Something like 80% of all Earth fossils are marine. From the very beginning, they've been looking for signs of life. The search for water is a subset of the main goal of looking for life. Mariner 4 calculated that liquid water could not exist on Mar's surface. The Viking orbiters were looking for signs of ancient water to determine if life could have existed in the Martian past. Since they figured out that multicellular life was a no go, the Viking probes went to Mars in the 1970s to specifically look for single-celled organisms and organic matter. The Phoenix lander of 2008 had two goals: look for life supporting habitable zones and of course, to look for geologic signs of water. All the future Mars missions on the drawing board have one purpose. To look for signs of life! So far none of the evidence has met the criteria and parameters for exo-biologic origin. Humans are a lonely herd. We just can't believe that we're all alone. It's hard to accept that the closest, most Earth-like planet we can imagine is a cold, desolate, lifeless place. ----------------------------- Support bacteria - they're the only culture some people have.
