Abstract

The characteristics of very large (10-1000 m diameter) orbiting-liquid mirror telescopes (OLMTs) continuously accelerated by the radiation pressure from the sun on solar sails are considered. OLMTs in halo orbits can be used for pointed observations. Orbit patching would allow access to different regions of the sky. Several practical considerations and issues are addressed.
