pia08387_croppedAstronomers have paired the Cassini spacecraft with the National Science Foundation’s Very Long Baseline Array (VLBA) radio-telescope system to pinpoint the position of Saturn and its family of moons to within about 4 km. That’s about 50 times more precise than those provided by ground-based optical telescopes, improving out knowledge of Saturn’s orbit and benefiting spacecraft navigation and basic physics research.
