ALIEN SOUNDSCAPES

Crackling electricity in the atmosphere" Howling red dust storms" Sounds that become muffled from just a few feet away" At session 3aPAb, researchers will present the latest theoretical and experimental knowledge on acoustical conditions on several other terrestrial bodies in our solar system. In addition, Martin Towner of The Open University in the United Kingdom (martintowner@googlemail.com) and others will discuss the acoustic instrumentation that has been flown to date in space missions, particularly the Huygens probe that landed on Saturn's moon Titan (3aPAb1). John Zarnecki of The Open University (j.c.zarnecki@open.ac.uk) will explain how the Huygens probe deployed a simple sonar system and speed-of-sound sensor to constrain the methane content on the planet and provide information on surface properties such as terrain topography (3aPAb4). Jean-Pierre Williams (jpierre@gps.caltech.edu), Andi Petculescu (U. of Louisiana at Lafayette, andi@louisiana.edu), and Amanda Hanford of Penn State University (ald227@psu.edu) will present computer simulations and theoretical models that predict acoustic propagation in the atmospheres of various bodies such as Titan, Venus, and Mars (3aPAb3, 3aPAb5, 3aPAb6). Gregory Delory of UC Berkeley (gdelory@ssl.berkeley.edu) will discuss what was intended to be the first audio microphone deployed on another planet--the Mars Microphone for the ill-
