We examine the conditions under which material from the martian moons Phobosand Deimos could reach our planet in the form of meteorites. We find that thenecessary ejection speeds from these moons (900 and 600 m/s for Phobos andDeimos respectively) are much smaller than from Mars' surface (5000 m/s). Thesespeeds are below typical impact speeds for asteroids and comets (10-40 km/s) atMars' orbit, and we conclude that the delivery of meteorites from Phobos andDeimos to the Earth can occur.
