QUESTION: 
Is it possible to record noise on Mars using MPF instruments, even though
the Pathfinder isn't equipped with a microphone? For example, could you use
the thermocouples on the ASI/MET mast, the accelerometers, or the Tavis
magnetic reluctance diaphragm sensor to listen to the surface of Mars?

ANSWER from Bruce Jakosky on October 7, 1997:
Unfortunately, these techniques are not really feasible.  The sensitivity to
sounds on Mars, as opposed to electronic noise, antenna pointing
uncertainty, etc., is sufficiently small that no information would get
through.  I understand that the 1998 lander will carry a small microphone
specifically for the purpose of listening to the sounds of Mars.
