The passage around this formula
Cassini flew six flybys of Titan between 2006 and 2011 with a gravity-quality radio link, and Iess and colleagues recovered = 0.589 0.150 , with an alternative solution of 0.637 0.224 [ 14 ] . Both are far too large for a rigid ice shell over rock and are consistent with a global ocean at depth [ 14 ] . The measurement did not see the ocean; it measured how much the whole moon flexes each orbit, and only a decoupled shell flexes that much.
