Hi Tom,

I don't think it was considered a feasible goal on any lander for Mars. Due to the high winds of Mars - any readings would be suspect, so one would have to build a seismometer which only takes readings when detected windspeed is zero or near zero.

The only truly accurate seismometer would have to be able to bury itself like a gopher or be deposited with a drill so as to insure it is out of the wind buffeting.

The moon and its lack of atmosphere provided an easier testbed for certain instruments.

Of course the lack of an atmosphere around a world may lead to the ringing effect which takes place upon the moon - as the atmosphere is a natural boon for absorbing vibrations and limiting resonance.

Maybe one was on the drawing boards for one of the landers but was cut for practicality and expense reductions.
