A large number of Transient Lunar Phenomenon (TLP) has been reported since the 17 th century. TLP's are apparent short term, regional changes on the moon. Although there are a number of different possible explanations on the real nature of this phenomenon, a conclusive one does not exist yet due to insufficient data. Some of the explanations are differences in reflections, Impact flashes, out gassing events or observation errors. One category of TLP's occur only for a few seconds or even less, which makes a continuous observation necessary in order to "catch" such an event.For this purpose, a dedicated, novel, and low cost TLP observation satellite mission consisting of two satellites is described here. The satellite constellation would operate in low earth orbit in order to have the full moon disk in the field of view. The optical payload would be continuously operating and pointing towards the moon. Detection, storage and transmission of short video sequences from autonomously detected events would be performed automatically. An alert mechanism, which passes the relevant detection data to a ground based telescope network or moon orbiting satellite operators for timely additional observation (e.g. via ORBCOMM), would complete the system.
