Identical dust detectors are flown on board the Galileo and Ulysses spacecraft. They observe dust in the ecliptic plane from r = 0.7 to r = 5.4 AU heliocentric distance and in a plane almost perpendicular to the ecliptic from ecliptic latitude lambda = -80 to lambda = +80 deg. Interstellar dust grains of up to micron-sizes dominate the measurements in the outer solar system, r > 3 AU, and at latitudes lambda > 30 deg. bigger (1 to 10 micron-sized) interplanetary meteoroids where found predominantly inside that distance and closer to the ecliptic plane. The combination of both the Ulysses and Galileo data sets allows us to determine the radial and latitudinal distributions of these dust populations. It is found that interstellar dust grains penetrate undepleted the solar system at least down to 1.3 AU distance from the sun and that they contribute about 30% to the total dust flux observed there.
