LAGRANGE : LAser GRavitational-wave ANtenna at GEo-lunar L 3 , L 4 , L 5

This white paper describes a space gravitational wave mission concept consisting of three dragfree spacecraft at the Earth-moon L3, L4, and L5 Lagrange points. It also describes a Gravitational Reference Sensor (GRS) instrument concept, an Interferometric Measurement System (IMS) concept, and enabling technologies for drag-free propulsion, charge management and material coatings. The primary submitter is John W. Conklin for the team members listed above. We are willing to present this concept at the workshop and there is no sensitive or controlled information herein.
