Student Mars Microphone : a Student Project for ExoMars 2016

• Proposal to lead a University consortium to contribute to ExoMars 2016 with a (light !) student project.

• Proposed structure : Consortium of European Universities

Involvement of undergraduate students

Coordination with associations (Eyes in Space, Planetary Society) for outreach.

• Institut Supérieur de l’Aéronautique et de l’Espace A leading engineering Institute in Europe Merging from SUPAERO and ENSICA engineering schools

A Short History of Planetary Microphones

• First Planetary microphone on Huygens Successfully retrieved the descent sounds

• Second opportunity on Mars Polar Lander MM Development up to FM by Greg Delory (UC Berkeley) Support by the Planetary Society Failed landing of MPL

• Third opportunity with Phoenix : sound coupled with Mardi imager (Not used)

• Opportunity on NetLander Stereo – Implementation on PanCam. Development stopped with NetLander
