Mission Objectives:

LARES and LARES-2 will achieve important measurements in gravitational physics, General Relativity, space geodesy and geodynamics, in particular, together with the LAGEOS-1 and LAGEOS-2 satellites and with the GRACE models, it will provide a very accurate determination of the Earth gravitomagnetic field and of the Lense-Thirring effect.

Mission Instrumentation:

The LARES satellite is covered with 92 uncoated cube corner reflectors made from Suprasil 311. Each cube measures: height=27.889 mm, diameter=38.10 mm.

The LARES-2 satellite is covered with 303 uncoated cube corner reflectors made from Fused silica Corning 7980. Each cube measures: height=19.05 +/- 0.25 mm, diameter=25.4 mm.
