The National Space Development Agency of Japan (NASDA) have deployed three sets of two passive experiments on the exterior of the Russian Service Module on the International Space Station: the Micro-Particles Capturer and the Space Environment Exposure Device, known collectively as MPAC&SEED. The MPAC segment of each unit consists mainly of a front and back face, nominally ram- and wake-pointing, each of which contains aerogel and polyimide foam tiles for capturing micrometeoroids and small space debris particles. In addition, the ram face contains a 6061-T6 aluminium witness plate. We provide a description of the MPAC, summarise the inspection and analysis performed to date, discuss the results so far achieved, and lay out our plans for the remainder of the work.
