COSMIC

Abstract

The design goals of the COSMIC spaceborne telescope array concept are outlined. These include a high degree of structural stiffness, a wide field of view, and a broad wavelength band. These properties directly enhance the scientific productivity and technical reliability of the array. If a sufficiently stiff structure can be designed, COSMIC can operate as a phased array; if the structure relaxes before it can be rephased on a reference star, it degrades to a coherent array. The COSMIC engineering study suggests that passively-stabilized, phased arrays are feasible.
