Closest Titan flyby
T70, 21 June 2010
880 km altitude!
Typically lowest flybys are ~950-970 km altitude -> 5000+ hrs of work by the Cassini team to assess spacecraft safety and determine the best orientation for passage through the atmosphere
Closer is better for magnetometer measurements
Below Titan’s ionosphere -> more sensitive to any magnetic signature originating from within Titan
