Deep space exploration is making a great progress by recent successes of landing and sample return missions to the Solar System small bodies such as Hayabusa 1 & 2. One of the most important problems of the Solar System science is to better understand the evolution of the primitive Solar System right after its formation. Thus direct exploration to small celestial bodies, in which material and structural information of the primitive Solar System are believed to be still well-preserved, is a next logical step after explorations to the near Earth asteroids.
Now, we are developing a small mass spectrometry system for onboard a space explorer probe. By using this instrument, we plan to conduct on-site analysis on the surface of small celestial bodies. This on-site analysis will allow to determine isotopic compositions of the surface materials, and the molecular compositions and abundances of the volatile compounds.
