LARES 2 (Laser Relativity Satellite 2) is a passive satellite with laser mirrors for the study of the Earth gravitational field and general relativity measurements (Lense-Thirring effect) and for geodetic purposes to improve the measurements on the LAGEOS 1 and 2 and LARES satellites.

LARES 2 is an improved version of LARES replacing the earlier LAGEOS 3 project, which was never funded. The main objectives of the LARES 2 experiment are accurate measurements of General Relativity, gravitational and fundamental physics and accurate determinations in space geodesy and geodynamics. In particular LARES 2 is aimed to achieve a very accurate test of frame-dragging, an intriguing phenomenon predicted by General Relativity.
