OBJECTIVES

   1. Apply disciplined planning to hunting for
        signals from the ISS over a period of months
        as done in radio astronomy.

   2. Experiment with different antennas,
        polarizations, and modes.

   3. Interact with ISS crew:  Flight Engineers
       Susan Helms and Jim Voss, Cmdr Yuri Usachev.

   4. Have an exciting diversion from traditional
       radio astronomy signal searching for JSS
       team members.
