Low frequency astronomy from lunar orbitAs part of preparation for establishing a permanently manned lunar outpost, a plan is proposed whereby relatively simple phased arrays of dipoles will be placed on individual lunar satellites to perform interferometry between the spacecraft. The dipole arrays will be deployed as inflatable structures. The experiment will function at 13 and 26 MHz. For a scenario in which two spacecraft are in perpendicular lunar polar orbits at altitudes of 100 km, the useful physical baselines will range from about 1 to about 1500 km. With a mission lifetime of one year, the two-element interferometer will produce synthetic aperture imaging with a resolution of about 2 arcsec.
