We report on the performance of a compact photon pair source that was retrieved from a failed space launch. The source had been installed in a nanosatellite and was found to be completely operational upon recovery. Comparison of post-recovery and baseline data suggests that there is no degradation in brightness or polarization correlation between photon pairs. We describe the assembly technique for the robust source. Its survival provides strong evidence that it is possible to design rugged quantum optical systems.
