The MATROS program (MApping TRojan Orbital Stability) has the goal to investigate the stability near the triangular Lagrangian points of the planets. We use Laskar's frequency analysis method to estimate diffusion rates of Trojan orbits in phase space. Diffusion portraits are derived for different orbital inclinations. In a november issue 2002 of ApJ, results for Saturn Trojans are presented. The same method has now been applied for Jupiter and Mars Trojans. Jupiter Trojans diffuse significantly slower than Saturn Trojans. Stability areas outlined by diffusion portraits show strong dependence on inclination. Work on Mars Trojans is in progress.
