NASA continues with their TRUE mandate
Exploring space. Instead of "padding their resume" with support for
B.S. global warming. Nasa sky survey probe blasts off A Nasa satellite designed to uncover hidden cosmic objects has blasted off from California. The Wide-field Infrared Survey Explorer (Wise) blasted off from Vandenberg Air Force Base on a Delta II rocket just after 1409 GMT. It will pick up the glow of hundreds of millions of astronomical bodies. The probe is expected to uncover objects that have never seen before, including some of the coolest stars and the most luminous galaxies. The $320m mission will do this by scanning the entire sky in infrared light with a sensitivity hundreds of times greater than ever before. Viewing the sky with "infrared glasses" can lift a veil on many objects that are not visible to the naked eye. “ Now we're ready to see the infrared glow from hundreds of thousands of asteroids, and hundreds of millions of stars and galaxies ” Ned Wright, UCLA "All systems are looking good, and we are on our way to seeing the entire infrared sky better than ever before," said William Irace, the mission's project manager at Nasa's Jet Propulsion Laboratory (JPL) in California. The satellite will also have a role in planetary protection: Wise will be able to detect some of the darkest near-Earth asteroids and comets. This would help efforts to determine whether any of these objects could strike Earth in the near future. Engineers acquired a signal from the spacecraft just 10 seconds after the spacecraft separated from the rocket. Approximately three minutes later, Wise re-oriented itself with its solar panels facing the Sun to generate its own power. Super cool Wise is cooled by a chamber of super-cold hydrogen. Because the instrument sees the infrared, or heat, signatures of objects, it must be kept at chilly temperatures. Its coldest detectors operate below -266C. "Wise needs to be colder than the objects it's observing," said Ned Wright of the University of California, Los Angeles (UCLA), the mission's principal investigator. "Now we're ready to see the infrared glow from hundreds of thousands of asteroids, and hundreds of millions of stars and galaxies." With the spacecraft stable, cold and communicating with mission controllers, a month-long process of check-out and calibration is underway. Wise joins two other infrared missions in space: Nasa's Spitzer Space Telescope and the European Space Agency's Herschel Space Observatory. This mission is different from those others in that it will survey the entire sky. It is designed to cast a wide net to catch a variety of objects of interest. Wise will target dim objects called brown dwarfs. These are effectively failed stars, which have not gathered up enough mass to ignite. Brown dwarfs are cool and faint, and nearly impossible to see in visible light. Mission scientists expect the spacecraft to uncover many hundreds. This could double or triple the number of star-like objects known within 25 light-years of Earth. |

Helping farmers in the U.S. determine what crops would be best to plant, looking out for insect infestations and marijuana farms are entirely legitimate space activities. You should actually be cheered to note that one part of rising sea levels, melting ice caps on the Himalays, have recently been found to be more the fault of soot from China than the world's carbon emissions... by new observations partly made by NASA.

I. Me. _I_ have a say in the actions others take, (often on my behalf, so they proclaim) about activities that affect the world I am in. I also have a responsibility to myself and others in that same regard. This is _not_ Rocket Science. Now, as to the Rocket Science; 320 Million Dollars is a lot of money. But it pales in comparison to many other scales of finance and I am in favor of exploration, discovery and teaching. Bully that it didn't blow up on the way up and I look forward to it's results over time. berk |

If the Chinese were that worried about the situation, they would stop producing things (including soot.) Will America take responsibility for its own coal burning?

Left gorgeous exhaust trails in the early morning sky (it was 6:10 AM here), almost like aurora borealis. I managed to snap a couple of pictures but actually haven't looked at them yet to see how they came out. -Frank -- Here's some of my work: http://www.franksknives.com/ |

Is Chinese soot somehow inferior to American soot? No, it is superior in both density and amount. And pretty unnecessary in the first place.

Soot is a lot easier to fix than CO2 emissions. Soot is carbon that wasn't burned. And it is reasonably easy to filter. It is an even better proposition to burn the carbon properly (i.e. hot enough) so the soot gets burnt in the first place. Most western carbon burning plants already have soot filtering in place, or burns sufficiently hot so they generate very little soot in the first place. The soot problem generally comes from small furnaces, burning wood etc. EU norms for small fireplaces went into effect a decade ago to properly burn wood etc. with very low amounts of soot. These norms also generally give a significantly higher useful heat output per burnt mass than the old one, so the soot avoidance is really just good housekeeping. If you want to control a stove with the supply of air (the normal method) then you need a secondary burn chamber with extra air supply to properly burn the CO and soot. Generating soot is just dumb. -- mrr |

In my world we have cars and trucks instead of buses and bicycles. In my world, one gets to keep more of what one earns, and share it only (and voluntarily) with those whom we consider most deserving. |
