The lunar surface is often identified as the ideal location for a large radio observatory for imaging at frequencies below ~10 MHz. Such observations cannot be done by terrestrial observatories because the radio waves are blocked by the ionosphere, i.e., the ionospheric cutoff. The goals of the lunar radio observatories include imaging solar radio bursts, observing the spectrum of the cosmological dark ages with good angular resolution, detecting the magnetospheric radio emissions of planets outside the solar system, and other astrophysical targets. Prior to the deployment of such a large radio observatory on the lunar surface, deploying a few antennas as a pathfinder mission is critical. In this presentation, we examine several mechanisms being tested to deploy such antennas from a small craft lander. Each concept has advantages and disadvantages, and to some extent, the best solution may be determined by the terrain at the landing site. Simple tests conducted at NASA GSFC will be presented. Other testing has taken place at Jet Propulsion Laboratory. A small system like the proposed pathfinder could detect the low frequency cutoff of the galactic radio background or of solar radio bursts, providing a determination of the maximum lunar ionospheric density at the time of measurement. These activities are funded in part by the NASA Lunar Science Institute as an activity of the Lunar University Network for Astrophysical Research (LUNAR) consortium. Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.
