AbstractISAS's MUSES-C mission will be launched in May 2003 and attempt the world's first asteroid sample return. The target is 1998SF36, a sub-km, S-type asteroid. In order to maximize scientific output from recovered (mostly) powder samples, in June 2007, the samples should be distributed to as many qualified researchers upon proposals from all over the world. Yet, such detailed analysis proposals must rely on general characteristics of the samples studied by the initial analysis team, MASPET. MASPET will consist of ISAS scientists, NASA and Australian Co-Is, and Japanese researchers from outsourcing institutions, most of who will be selected through the open competitions of mostly non-destructive, microanalysis techniques in respective disciplines needed during the initial analysis stage. They will work as one "all-Japan" team and are responsible for characterizing the general features of the bulk and some of major samples. They also must make acquired data available to the public, after the first results published within a year from the capsule touch-down, so that international scientists can refer them and request samples for suitable, detailed analyses accordingly. The first competition was conducted in 2000-2001 and the MUSES-C Sample Advisory Committee endorsed the final recommendation in May 2002. A total of eleven applications from a large variety of analytical disciplines was received and peer-reviewed. Nine of them received two sets of unknown test samples to demonstrate their self-claimed analytical performance. Multiple international referees evaluated their reports and 6 of them were recognized as qualified to join the MASPET as of 2002. These "unknown" samples were the UNSM3529 fraction of Allende (CV3) and Valdinizza (L6). The competition will be repeated once more after the spacecraft launch and the final membership of the MASPET should be decided in the late 2005, right after the spacecraft leaves the asteroid.
