StarDust or EarthDirt?
StarDust or EarthDirt?
Would extremely small pieces of Stardust impact somewhere within the aerogel? 10,100,1000,... atoms, at some point it would miss the aerogel for a little while and impact somewhere in it's interior. I would expect that the impact craters within the aerogel would go the full range of sizes. From large fragments, http://stardust.jpl.nasa.gov/images/2trackposter.jpg http://stardust.jpl.nasa.gov/images/5trackposter.jpg down zero, or really small. http://johnnyp.tag2087.com/tracks001.jpg ftp://stubbs.ws/stardust/nexguy.PNG http://stardustathome.ssl.berkeley.e...movie_id=41130 http://stardustathome.ssl.berkeley.e...movie_id=42180 so these might be reasonable pieces of stardust. Or, EarthDirt. Do they have before pictures to compare to the after pictures? The before pictures would show how much contamination is within the Aerogel. -- Craig Fink Courtesy E-Mail Welcome @ |
