How Big Is the Voyager 2 Probe

However, Dr. Thomas explained to the press in May 2013 that the ring arcs are much more tenuous than the fully formed rings of Saturn. As a matter of fact, the ring arcs are so delicate and thin that it would take about ten billion years for just 1 meter of blowing icy snow to collect within the craters of Methone. "We are just beginning to try and figure out quantitatively how all this might smooth a surface," Dr. Thomas said in the May 17, 2013 New Scientist. Dr. Soderblom and his team, including Dr. Maria Zuber, who is the E.A. Griswold Professor of Geophysics and MIT's vice president of research, have published their findings in the September 10, 2015 issue of the journal Geophysical Research Letters.
