"NASA scientists hope to hear what it sounds like on the surface of
Mars for the first time when they attempt to switch on the Phoenix
Mars Lander's microphone..."

Not only that, but an additional imager ..
"The imager might also catch a glimpse of some so-called "barnacles"
attached to Phoenix's legs. Smith describes these as "bright dots on
the legs" that are pieces of the Martian surface that were splashed
onto the legs by the thrusters during landing."
"Some of the dots have grown and some have moved around over the
course of the mission, which is now entering its fifth month on the
Martian surface. Mission scientists aren't sure why the dots have
such unusual behavior."
