Oh dear..... clueless ESA thinks it discovered water on Mars...
In recent years a few Americans have started to worry about Europe falling far
behind the United States. I am so glad that Europe has finally got around to discovering water on Mars. ;-) A discovery which America appears to have made over 30 years ago. Below are some quotes from "On Mars: Exploration of the Red Planet" http://history.nasa.gov/SP-4212/ch11.html From a description of MAriner 7, which flew past MArs in 1969. "Mariner 6 and 7 data did strengthen the earlier conclusion that water was extremely scarce on Mars and that was a seriously limiting factor for the search for life. While no clouds, frosts, or fogs had been seen in the new pictures, minute amounts of water vapor had been detected in the atmosphere." (Ch 6 ,Section 180) From a description of the infrared instrument on the Viking orbiters, which orbited Mars in 1976. "A more important contribution from the infrared thermal-mapping experiment was the discovery of the nature of the polar ice cap. One of the major questions posed by the Mariner 9 data was the composition of the residual polar cap left when the winter polar cap, made of frozen carbon dioxide, retreated in midsummer. A major controversy existed over whether this summer cap seas also frozen carbon dioxide or was frozen water. According to Viking data, the temperatures of the residual cap are near -68° to -63°C, making a case for water frost." (Ch11,Section 373) " The water-vapor-mapping investigation was designed to map the distribution of water vapor over the planet and to determine the pressure of the atmosphere at the level where vapor is present. Understanding the distribution of water vapor is crucial to understanding the geological features of Mars and the possibility of the existence of life. Viking's measurements of water vapor varied, depending on the location, season, and time of day. snip Interestingly, while the amounts of vapor at some latitudes changed dramatically, the total global water remained almost constant at the equivalent of about one cubic kilometer of ice. The largest amounts observed were found over the dark polar region, which is inaccessible to Earth-bound observers. Maximum vapor column abundances of about 100 precipitable micrometers were measured adjacent to the residual cap itself-a very large amount considering the temperature of the surface and atmosphere in this region." The Mars atmospheric water detector also confirmed the conclusion that the residual cap is made of frozen water and that the atmosphere above it is saturated with vapor during the polar summer. 23 " (Ch11,SEction 374) And here is a Dec 6, 1998 release from NASA on the results of the laser altimeter carried by Mars Global Surveyor. "This first three-dimensional picture of Mars' north pole enables scientists to estimate the volume of its water ice cap with unprecedented precision, and to study its surface variations and the heights of clouds in the region for the first time." http://ltpwww.gsfc.nasa.gov/tharsis/agu_f98.html MAny people are also aware of the detection of hydrogen ( and hence water) by Mars Odyssey's neutron spectrometer. I'm not sure wether this story about Europe "discovering " water on Mars is the fault of ESA or clueless journalists. ESA's website and the BBC appear to have a clue and don't call this a discovery. However, it does sound as if some ESA scientists said it was. What really concerns me is the apparent inability of European scientists to conduct a basic literature search. It really make you wonder about the competence of Europe's Mars reseachers. From this side of the Atlantic they look like first-class idiots. |

ESA announced that it had discovered water at the south polar cap; this is a first. Water had been known elsewhere, and there were strong indications that it was present in the South, but this had never been proven.More to the point, the didn't discover strong evidence for water, or indirect evidence of it being there, they actually observed it. They put out a press release saying, in essence, "We found water on Mars - here's the gist..." and then suffered from a large number of journalists not bothering to quite get past the first couple of words. -- -Andrew Gray |

Yes. In fact the article about it in the French Libération newspaper clearly states that. "Après les observations de Viking dans les années 70, on connaissait la présence d'eau au pôle Nord. Cette fois, nous avons sa confirmation au pôle Sud." [After Viking observations in the 70's, we knew there was water at the North pole. This time, we confirm its presence at the South pole.] If the journalist from your local newspaper didn't parse carefully the ESA anouncement, don't blame European scientist for it. Alain Fournier |

Alain Fournier Nice try. I'm afraid the American public is more interested in a math-and-science-free "USA! USA! USA! vs. The World Battle" than real news and analysis. The press is giving them what they want. I'm not in Europe, but I'm guessing their news media are just as superficial at times. Let's hope the scientists everywhere are passing up on this BS and working on getting the most out of these space probes. Corry -- It Came From C. L.

I don't believe they're idiots at all. I suppose it's possible that they
truly think they're "first" with this discovery, as the European mindset about things American is pretty warped at times, but I believe it's more a matter of a desire to manipulate the media with triumphalism. As I noted in another post, 'news' coming out of Europe the past several years has the familiar nationalistic ring of the People's Daily reporting on China, whereas in America the news tends to always skew toward the problems, potential problems and concerns. |

Alain Fournier This is another idiotic Usenet argument that I certainly hope is confined to the clueless though usually well informed group that is constantly looking for something to complain about and particularly if it involves bashing Europeans. The Europeans reviewed the previous data obtained by NASA probes and satellites and chose a set of instrumentation to get new data sets. They found what their instruments interpreted as water from their new findings and put out a press release on the matter. Their readings were new data and apparently covered either a different region than the NASA data or covered it in more detail. The only people who look like first class idiots are those who accuse the European scientists of failing to do a proper literature search and base the remarks on a press release quoted from the media.

"Géraud des Courtils" wrote in message ... For the first time ever, some water (ice) has been discovered on Mars, BY A DIRECT WAY, thanks to the devices built on board Mars Express. **snip** You have been corrected and even included the correction in your post. Yet you cut and paste your original statement over it without even contesting the arguments against you. You, hearby, show yourself to be a lying troll. |
