Cum il putem deosebi pe MGeoana de CAntonescu?


    Devine tot mai simplu de facut aceasta diferenta intre candidatul PSD si cel de la PNL pentru presedintia Romaniei (desi cresc asemanarile dintre PSD si PNL – ma gindesc inclusiv la reactia celor doua partid vizavi de Raportul CE).
    E drept ca ne cam ajuta si cei doi 🙂
    Cum anume putem face aceasta distinctie si cum putem avea garantia faptului ca nu vom face vreo confuzie, va spun intr-o postare viitoare 🙂 Poate chiar in urmatoarea…

    1. STORY WRITTEN FOR & USED WITH PERMISSIONPosted: January 15, 2005A missing computer command – apparently the result of human error – caused the loss of half the pictures taken by Europe’s Huygens probe as it descended to the surface of Saturn’s moon Titan. But project officials said today the 350 pictures that made it back, along with high-quality data fromthe spacecraft’s other instruments and unexpected measurements by Earth-based radio telescopes, should fulfill all of the mission’s primary objectives. This color image was returned January 14 by ESA’s Huygens probe during its successful descent to land on Titan. Initially thought to be rocks or ice blocks in front of the probe, they are more pebble-sized. The two rock-like objects just below the middle of the image are about 15 centimetres (left) and 4 centimetres (centre) across respectively, at a distance of about 85 centimetres from Huygens. The surface is darker than originally expected, consisting of a mixture of water and hydrocarbon ice. There is also evidence of erosion at the base of these objects, indicating possible fluvial activity. Credits: ESA/NASA/University of Arizona”I’m very, very happy to report that we have received a very good dataset that will surely allow us to achieve all of our objectives and probablymore than what we had initially set out,” said Jean-Pierre Lebreton, theEuropean Space Agency’s Huygens project scientist. „We can now start to seea clearer picture of Titan emerging.”Researchers today unveiled a dramatic 360-degree panorama shot by Huygensdescent imager showing the probe’s path across the moon as it descendedtoward touchdown. The mosaic put in context three photos released Fridayshowing channels, an apparent shoreline, an unusual heart-shaped feature andwhat appeared to be ice blocks at the landing site itself.You can see our montage of Huygens pictures showing the landing area .The mosaic shows the channels and shoreline behind Cassini with thelanding site, near the heart-shaped feature, dead ahead. The channels inlight-shaded, elevated terrain flow down toward what look like a shorelinealong large expanses of dark, smooth-looking areas. It’s not yet knownwhether ethane, methane or other hydrocarbons exist in liquid form in theseareas, but additional data analysis may resolve the matter in the weeks andmonths ahead.”It’s almost impossible to resist the speculation that this flat, darkmaterial is some kind of drainage channel, that we’re seeing some kind of ashoreline,” said University of Arizona researcher Martin Tomasko, principalinvestigator with the descent imager team. „We don’t know if this still hasliquid in it or whether the liquid has drained away or drained into thesurface. You have the feeling maybe this was wet not so long ago.”Tomasko also unveiled a color version of a photo released Friday thatshowed what appeared to be ice boulders strewn across the surface near theHuygens landing site. The boulders, Tomasko said today, were actually closerin size to pebbles, based on additional data analysis. But he saiddepressions in the surface material around the small rock-like chunks of iceindicated possible erosion patterns due to the flow of some as-yet-unseenliquid.Huygens entered Titan’s thick nitrogen atmosphere around 5:13 a.m.Friday. John Zarnecki, principal investigator of the surface sciencepackage, said it took the spacecraft two hours 27 minutes and 50 seconds tocomplete its parachute descent to the surface. It hit that surface at avelocity of 10.1 mph and experienced a very brief impact deceleration of 15Gs. The jolt knocked one sensor off line, but it came back to life on itsown a few minutes later.A „penetrometer” on the bottom of the probe extended six inches into thefrigid soil. That data, coupled with the deceleration experienced by Huygensas it hit the ground, provided new insights into the nature of the surfacematerial at the landing site.”What we’re seeing is, we think, a material which might have a thin crustfollowed by a region of relatively uniform consistency,” said Zarnecki. „Interms of this (impact) force, the closest analog that I can give you – andremember, this is not suggesting these are the materials we hit, but thatthe mechanical consistency is similar – then I would say wet sand or clayare materials which give a similar sort of trace.”PHOTO: PHOTO: PHOTO: PHOTO: PHOTO: Huygens sampled the atmosphere as it floated toward the surface in windsmeasured at about 16 mph between six and 12 miles altitude. A microphoneeven recorded the sound of the wind rushing past. On-board instrumentsdetected a thick methane haze, or cloud deck, 11 to 12 miles above theground where atmospheric pressure measured about 7.3 pounds per square inch.The outside temperature when the descent began was 70.5 Kelvin, or minus332.8 degrees Fahrenheit, while the temperature on the surface was slightlywarmer: 93.8 Kelvin, or minus 290.8 degrees Fahrenheit.Huygens was programmed to transmit telemetry and scientific data toNASA’s Cassini Saturn orbiter for relay to Earth using two redundant S-bandradio systems. Channel A was the sole path for an experiment to measure windspeeds by studying tiny frequency changes caused by Huygens’ motion. In oneother deliberate departure from full redundancy, pictures from Tomasko’sdescent imager were split up, with each channel carrying 350 pictures.As it turned out, Cassini never listened to channel A because of asoftware commanding error. The receiver on the orbiter was never commandedto turn on, according to officials with the European Space Agency.”We should remember we’re human and we should learn lessons, so I willinstitute an ESA inquiry on how the command came to be missing,” DavidSouthwood, director of science for the European Space Agency, told reporterstoday. „I’m not going to say any more about that, I’m not going to speculate(about blame).”In an obvious reference to NASA and earlier news reports, he did say”there have been some erroneous messages implicating one of the other spaceagencies involved. No. It’s an ESA responsibility.”According to published reports, an ESA official said earlier that themissing command was part of a software load developed by ESA for the Huygensmission and that it was executed by Cassini as delivered.”There isn’t any doubt that the command was missing,” Southwood saidtoday. „But I’m not going to say any more because the point of an inquiry isto find out. We will certainly have NASA representation on the inquiry, butI don’t want to make a big thing about it.”Tomasko said that before the mission began, his team debated whether tosend all pictures and spectral data in two independent sets using channels Aand B to ensure full redundancy. In the end, they decided to send spectraldata through both channels but to double their picture output by sendingdifferent photos through each radio. The loss of channel A means the teamonly gathered 350 pictures instead of the 700 planned.”So we do have some holes in our panoramic mosaics, but we have a lot ofoverlap in our coverage and I think we can still do a fine job,” he said. „Ithink the quality of the images will continue to get better … as weassemble these mosaics in the days and weeks ahead.”Even the lost wind measurement data will be made up, thanks to aremarkable effort on the ground to monitor a faint carrier signal broadcastby Huygens – the equivalent of a cell phone call at a distance of 751million miles – using a network of 18 radio telescopes around the world.That data, which not as precise as the Doppler information that was lost,should fill in the blanks.Leonid Gurvits, a researcher with the Netherlands-based Joint Institutefor Very Long Baseline Interferometry in Europe, said his team achieved windspeed accuracy levels of one meter per second, or 2.2 mph even thoughHuygens was three-quarters of a billion miles away.”Just as there are malign gods, there are benign gods and with anextraordinary effort that i still frankly can’t believe, the radioastronomers of the world gathered together to look at the littletelephone-level signal coming from the other side of the solar system andwe’re
      expecting that will be able, with an enormous amount of work … wewill get back wind profiles as we need to get our full picture of the Titanatmosphere.”Video coverage for subscribers only:VIDEO:THE NEW PICTURES PRESENTED WITH EXPERT NARRATION VIDEO:LISTEN TO SOUNDS FROM HUYGENS WITH NARRATION AUDIO:LISTEN TO SOUNDS FROM HUYGENS WITH NARRATION VIDEO:RESULTS FROM HUYGENS’ SURFACE SCIENCE PACKAGE VIDEO:CHIEF SCIENTIST EXPLAINS COMMUNICATIONS ERROR VIDEO:TODAY’S PHOTO AND SCIENCE BRIEFING AUDIO:TODAY’S PHOTO AND SCIENCE BRIEFING VIDEO:THE FIRST PICTURE FROM HUYGENS IS REVEALED VIDEO:HUYGENS POST-LANDING NEWS BRIEFING VIDEO:STATUS REPORT DURING DESCENT AUDIO:MISSION STATUS REPORT DURING DESCENT VIDEO:HUYGENS PRE-ARRIVAL NEWS BRIEFING AUDIO:HUYGENS PRE-ARRIVAL NEWS BRIEFING VIDEO:OVERVIEW OF HUYGENS PROBE’S SCIENCE OBJECTIVES VIDEO:JULY NEWS BRIEFING ON CASSINI’S PICTURES OF TITAN VIDEO:PICTURES SHOWING TITAN SURFACE FROM OCT.
