Scientists Pinpoint Saturn With Exquisite Accuracy: Scientists have paired NASA's 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 2 miles (4 kilometers). The measurement is some 50 times more precise than those provided by ground-based optical telescopes. The feat improves astronomers' knowledge of Saturn's orbit and benefits spacecraft navigation and basic physics research.
