This paper discusses the use of very low frequency aperture synthesis as a probe of astrophysical phenomena. Specifically, the science achievable with the Lunar Observer Radio Astronomy Experiment (LORAE) that cannot be performed optimally from the Earth. The density distribution and the degree of turbulence of the galactic plasma can be determined from its effect on background radio sources. These same absorption phenomena can be used to determine magnetic field strengths within astrophysical plasma. Detection of unabsorbed synchrotron emission can provide information on the relativistic plasma component. The detection of new pulsars may prove feasible because of their steep spectra.
