N2 - With the Japanese IR Astronomy Satellite, AKARI, we have performed a far-IR imaging survey of extended cold dust shells around evolved stars. Our observations yield far-IR surface brightnesses of these shells, from which we can reconstruct the history of mass loss (as a function of time) during the critical epochs of mass loss near the end of the asymptotic giant branch phase. Below, we will present the motivation of the study, review the past studies, introduce the AKARI Astronomy Satellite and present a glimpse of the preliminary results of the MLHES Mission Programme.
