Solar system observations and future missions

This paper aims at placing infrared (IR) and submillimeter (submm) observations of the Solar Sytem in the context of future space missions. First, the information that mm, submm and IR observations bring on planets, satellites and comets is reviewed. Then, some lines of future research in this field are explored, and a number of observations that could enhance our understanding of Solar System objects are suggested. Finally, the adequacy of future space missions in this respect is discussed. The specific cases of ISO, FIRST and the proposed Edison are considered.
