Pioneer measures Saturn's ring structure


  • Anonymous


The first findings about Saturn have come from early pictures of the planet returned by the Pioneer spacecraft. Pioneer completed the first trip to Saturn on September 1.

These early findings show that there are roughly equal amounts of ring material in a region of the outer rings, specifically in or near Cassini's Division, and in Saturn's inner C-ring. It is believed that there is material in Cassini's Division which separates the outer A- and B-rings, but not much is known yet.
