NASA's Cassini Spacecraft Skims Saturn's Rings
Today, November 30, 2016, NASA's Cassini mission began a set of ring-grazing orbits, skimming past the outside edge of Saturn's main rings. Now in its final year of operations, this is the closest study of the rings and will offer unprecedented views of moons that orbit near them. These orbits bring Cassini within nearly 5,000 miles of Saturn's F ring, which marks the border of the main ring system.
