Lunar Gravitational-wave Antenna

Monitoring of vibrational eigenmodes an elastic body excited by gravitational waves was one the first concepts proposed for detection waves. At laboratory scale, these experiments became known as resonant-bar detectors developed Joseph Weber in 1960s. Due to dimensions bars, targeted signal frequencies were kHz range. also pointed out that monitoring vibrations Earth or Moon could reveal mHz band. His Lunar Surface Gravimeter experiment deployed on Apollo 17 crew had a technical failure rendering data useless. In this article, we revisit idea and propose Gravitational-Wave Antenna (LGWA). We find LGWA become important partner observatory joint observations with space-borne, laser-interferometric detector LISA, at same time contribute independent science case due LGWA's unique features. Technical challenges need be overcome deployment experiment, development inertial vibration sensor technology lays future path exciting concept.
