Abstract
FOUR LITTLE SENSORS, INSTALLED upside down, caused the crash onto the Utah desert of a capsule of solar-wind samples collected by the National Aeronautics & Space Administration's Genesis spacecraft. Most of the particle collectors aboard the craft were shattered, and all were contaminated in the September 2004 accident. But after a few weeks of sifting through the wreckage, Genesis scientists announced they believed they could salvage much of the project. Since then, the analysis has been slow, involving painstaking clean-room examination and removal of surface contamination. Not only are scientists finding that they can indeed extract solar-wind particles from the mess, but they also have gotten some of their first scientific results, which they reported last month at the American Geophysical Union annual meeting in San Francisco. We are not giving up on measuring anything that we've planned from the beginning, said Donald S. Burnett, geochemistry professor at California Institute of Technology and pr...
