But it is yet another example of something. If stuff like this is supposedly hard to come by, how come we are always coming by this stuff? Don't even get me started on extrasolar planets. Nope. I'm with Dallas Abbot on this one. |

I agree that Arecibo should be kept and even upgraded to whatever extent is affordably doable. However, of radar like except X-ray images that should outperform Hubble resolution by a million fold are within the near future, although perhaps a terrestrial gamma transmitting and gamma receiving telescope could best replace Arecibo at 10% the annual cost of sustaining those old but nicely proven methods that have somewhat limited resolution. .. - Brad Guth |

NASA shelves climate satellites Environmental science may suffer By Beth Daley, Globe Staff | June 9, 2006 NASA is canceling or delaying a number of satellites designed to give scientists critical information on the earth's changing climate and environment. The space agency has shelved a $200 million satellite mission headed by a Massachusetts Institute of Technology professor that was designed to measure soil moisture -- a key factor in helping scientists understand the impact of global warming and predict droughts and floods. The Deep Space Climate Observatory, intended to observe climate factors such as solar radiation, ozone, clouds, and water vapor more comprehensively than existing satellites, also has been canceled. And in its 2007 budget, NASA proposes significant delays in a global precipitation measuring mission to help with weather predictions, as well as the launch of a satellite designed to increase the timeliness and accuracy of severe weather forecasts and improve climate models. The changes come as NASA prioritizes its budget to pay for completion of the International Space Station and the return of astronauts to the moon by 2020 -- a goal set by President Bush that promises a more distant and arguably less practical scientific payoff. Ultimately, scientists say, the delays and cancellations could make hurricane predictions less accurate, create gaps in long-term monitoring of weather, and result in less clarity about the earth's hydrological systems, which play an integral part in climate change. ``Today, when the need for information about the planet is more important than ever, this process of building understanding through increasingly powerful observations . . . is at risk of collapse," said Berrien Moore III, director of the Institute for the Study of Earth, Oceans, and Space at the University of New Hampshire. Moore is cochairman of a National Research Council committee that will recommend NASA's future earth science agenda later this year. It is unclear, however, whether NASA will follow those recommendations. ``NASA has canceled, scaled back, or delayed all of the planned earth observing missions," he said. Despite NASA's best-known role as a space agency, one of its key missions is to study the earth. Scientists collect data through ground- and space-based observatories using instruments that can sense heat and through which they can see with exquisite detail from many miles up. In recent years, these missions have increased in importance and visibility as global temperatures rise and scientists rush to better understand the phenomenon and the role of humans in it. While NASA is proposing similarly deep cuts to other important science programs such as astrobiology -- the search for life in space -- the earth science mission cancellations and delays take on greater significance, some scientists say, given recent allegations by a top NASA researcher and other government scientists that the Bush administration tried to silence their warnings about global warming |

Of what you report is 100% true, and most likely the best available
truth about our resident LLPOF warlord(GW Bush) doing nasty sorts of things in order to moderate over the scientific truths about global warming, because his fossil oil, coal and natural gas friends are not cutting emissions, and energy cost is soaring to boot. However, since when hasn't our cold-war perpetrating government lied to us? (we're also talking of trillions spent per decade) What do you think our NASA/Apollo rusemasters with "the right stuff" really accomplished to start with? .. - Brad Guth On Feb 15, 10:08 pm, "V-for-Vendicar" wrote: "BradGuth" wrote I agree that Arecibo should be kept and even upgraded to whatever extent is affordably doable.
