ESA Plans to Study Enceladus' Ice Thickness
Cassini's 2005 and 2015 data showed tidal heating from Saturn's gravity.
Infrared analysis showed north pole 7 K warmer than models, 46 mW/m² heat flow, 35 GW conductive loss.
Total heat loss of 54 GW aligns with tidal heating, supporting a stable subsurface ocean.
ESA plans 2040s missions to study Enceladus' ice thickness (20-28 km), with next challenge being ocean persistence.
