  The Near Earth Object Surveyor mission has a requirement to find two-thirds
of the potentially hazardous asteroids larger than 140 meters in size. In order
to determine the mission's expected progress toward this goal during design and
testing, as well as the actual progress during the survey, a simulation tool
has been developed to act as a consistent and quantifiable yardstick. We test
that the survey simulation software is correctly predicting on-sky positions
and thermal infrared fluxes by using it to reproduce the published measurements
of asteroids from the NEOWISE mission. We then extended this work to find
previously unreported detections of known near Earth asteroids in the NEOWISE
data archive, a search that resulted in 21,661 recovery detections, including
1,166 objects that had no previously reported NEOWISE observations. These
efforts demonstrate the reliability of the NEOS Survey Simulator tool, and the
perennial value of searchable image and source catalog archives for extending
our knowledge of the small bodies of the Solar System.
