    This looks interesting (and kind of fun)

    Measuring the Interplanetary Medium with a Solar Sail

          A solar sail mission to deep space could determine the density of
          the interplanetary medium by measuring the drag force on the huge
          sail with radiometric navigational data. Thus, a mission similar
          to the Interstellar Probe might consider retaining its sail beyond
          the orbit of Jupiter to measure the matter density in deep space.
          Such an experiment would a yield an independent, new type of
          measurement of the interplanetary medium and should be pursued.
