Three MPAC units were aboard the Russian SM (Service Module) of the ISS (International Space Station), performs experiments regarding capturing dust particles in orbit. Silica aerogels and polyimide foams are used as the dust (or the dust's fragments) capturing materials, and metal plates are used as measuring materials of dust fluxes. The MPAC unit is complete passive equipment and does need no electrical power or communication. The exposure duration of each unit is about 1, 2 and 4 years respectively. After the exposure duration, MPAC units were brought back to the earth and retrieved. One more unit is installed on the front surface of " KIBO" (JEM: Japanese Experiment Module). In this paper we describe on the overview of MPAC experiment, which includes (1) Development of the MPAC unit, (2) Hypervelocity impact experiments, and (3) Post flight analysis (PFA)., Physical characteristics: Original contains color illustrations, 資料番号: AA0064307007, レポート番号: JAXA-SP-08-015E}, pages = {49--58}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Overview of the MPAC experiment: Development of dust collectors, hypervelocity impact experiments, and post flight analysis}, volume = {JAXA-SP-08-015E}, year = {2009} }
