A Quick Summary of the OBSS Project
OBSS will provide the positions, proper motions, parallaxes, and photometry of nearly all stars as faint as 19th visual magnitude with accuracies of 50 microarcseconds at 9th visual magnitude and 500 microarcseconds at 15th visual magnitude. This is accomplished by a scanning survey instrument evolved from Hipparcos with a mission life of 5 years.

We have available a list of OBSS Quick Facts.
