QUESTION:
I noticed on the web that you send "wake up" songs to the Pathfinder much
like you do for the astronauts on the shuttle.  Where do these songs go? 
Surely there are no speakers on the lander or rover!  Do you simply transmit
the songs along with other data to the lander?

ANSWER from Smart Filter on 24 Aug. 1997:
The "wake up" song isn't really for the rover to hear at all. It's just a
tradition that the Pathfinder team started: They play a song daily to kick
off that day's mission activities.
