LROC, which may be the closest we have in volume to a lunar telescope, sends its data back to Earth. http://lroc.sese.asu.edu/about
LROC is one of seven instruments on board LRO. Together, these instruments have a downlink allocation of 310 Gbits per Ka band pass and up to 4 passes per day. That translates into 155 GBytes per day of data or 56,575 GBytes per year (55 TBytes). These data are processed by each respective instrument's Science Operation Center (SOC) with the final products being delivered to the NASA Planetary Data System (PDS).
