Public To Look For Dust Grains In Stardust Detectors By Robert Sanders Berkeley CA (SPX) Jan 11, 2006 Astronomy buffs who jumped at the chance to use their home computers in the SETI@home search for intelligent life in the universe will soon be able to join an Internet-based search for dust grains originating from stars millions of light years away. In a new project called Stardust@home, University of California, Berkeley, researchers will invite Internet users to help them search for a few dozen submicroscopic grains of interstellar dust captured by NASA's Stardust spacecraft and due to return to Earth in January 2006. Though Stardust's main mission was to capture dust from the tail of comet Wild 2 -- dust dating from the origins of the solar system some 4.5 billion years ago -- it also captured a sprinkling of dust from distant stars, perhaps created in supernova explosions less than 10 million years ago. "These will be the very first contemporary interstellar dust grains ever brought back to Earth for study," said Andrew Westphal, a UC Berkeley senior fellow and associate director of the campus's Space Sciences Laboratory who developed the technique NASA will use to digitally scan the aerogel in which the interstellar dust grains are embedded. "Stardust is not only the first mission to return samples from a comet, it is the first sample return mission from the galaxy." |

There is already a topic for this subject here: http://www.unmannedspaceflight.com/index.php?showtopic=1697 I kept wondering why there were no replies. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
