Abstract
We present the first results from an H2O maser survey conducted with the VLBA for determining candidate sources for space VLBI missions. We observed 60 sources in total: four late-type stars, 29 star-forming regions, and 27 H II regions. These are the first interferometric observations of any kind for 50% of the sources. Approximately 30% of the sources we observed exhibit highly compact structure and very strong emission, which make them ideal targets for space VLBI missions.Keywords
