Scientific paper

The present orbiting interferometer proposal for operation in the UV, visible, and near-IR spectral ranges employs a 6-m baseline and a collecting area equivalent to an approximately 1.4-m diameter aperture. The instrument, which is of Fizeau type and therefore possesses better UV throughput than phased arrays, is projected to be able to furnish resolutions superior to those of the Hubble Space Telescope, as well as to complement prospective ground-based interferometers with its greater limiting magnitude and spectral coverage. A single launch will suffice to place the system in GEO or sun-synchronous orbit, in order to minimize thermal and mechanical disturbances and maximize observing efficiency.
