Numerous proposals have been brought forward with respect to the lake-lander concept.
One of the most detailed plans so far is the so-called Titan Mare Explorer (TiME), which had originally been proposed as a separate scout mission, but might eventually be postponed and included in the TSSM.
If approved, TiME would be released by the orbiter on its second Titan flyby.
Due to Titan's haze layer and its  distance to the Sun, the lander cannot be powered by solar panels and it would rely on the new Advanced Stirling Radioisotope Generator (ASRG), which is a prototype meant to provide availability of long-lived power supplies for landed networks and other planetary missions.
The lander will target Ligeia Mare, a northern polar sea of liquid hydrocarbons at about 79°N. The probe will descend by parachute, like the Huygens probe of 2005.
During the 6 hours of descent it will analyze the atmosphere and then splashdown on the liquid surface.
The plutonium-powered craft's principal function is to sample and analyze organics on the surface for a period of about 3 to 6 months; this would be the first floating exploration of an extraterrestrial sea.
