This along with the evidence of volcanism on Mars not that long ago, and perhaps the ocean on Enceladous, suggest to me that either objects do not cool off as fast as previous science suggested, or there is/are other energy inputs other than object condensation and radioactive decay.
Perhaps excitation from the solar wind, or currents generated elsewise, perhaps by photons.
Done.

Mission Goals
Elucidate the nature of the Moon's lower crust and mantle by direct measurements of its composition and of sample ages.
Determine the chronology of basin-forming impacts and constrain the period of late, heavy bombardment in the inner solar system, and thus, address fundamental questions of inner solar system impact processes and chronology.
Characterize a large lunar impact basin through "ground truth" validation of global, regional and local remotely sensed data of the sampled site.
Elucidate the sources of thorium and other heat-producing elements in order to understand lunar differentiation and thermal evolution.
Determine ages and compositions of far-side basalts to determine how mantle source regions on the far side of the Moon differ from regions sampled by Apollo and Luna basalts.
