"[The transducer] would essentially be stuck on the surface and anything that moves the surface up or down would be picked up."Madaras and his team say they hope to identify and characterize the day-to-day background noises on the orbiting outpost so they will be able to develop a system that can pick out leak-generated noises from the clutter."The idea of giving [astronauts] more time, trying to help them out and get that part done so they can get to the leak, and now they have the tools to fix the leak," Madaras said. "That, to me, would be a good deal."</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
