The self-contamination of the SIRIO 2 spacecraft was studied using a computer program which models contaminant sources and contaminant interaction with spacecraft surfaces. The SIRIO 2 spacecraft is equipped with laser reflectors for clock-sychronization; these reflectors are contaminant sensitive. Computer prediction results are seen as inconclusive, mainly due to uncertainty in physical values for outgassing (flux in function of time; surface redeposition rate). Nonetheless, a contamination problem is identified relative to satellite venting ports locates the reflectors.
