The Spitzer Space Telescope has proven to be a powerful tool to measure the diameters and albedos of Near Earth Objects. We have completed two major Spitzer NEO surveys (ExploreNEOs and NEOSurvey) and are in the middle of a culiminating third survey (NEOLegacy), with a total target list across all three programs of 2175 previously known NEOs. We report here on the status of our ongoing program and of our entire database. We report our measured size distribution of NEOs as well as the distribution of albedos (and, by proxy, compositions). We also report preliminary results from our new initiative to derive lightcurves from our observations. Ultimately, more than 1000 NEO partial or complete lightcurves with high quality photometry will be extracted from our data. Our new website nearearthobjects.nau.edu includes data and modeling results from across all of our programs.This work is based in part on observations made with the Spitzer Space Telescope, which is operated by the Jet Propulsion Laboratory, California Institute of Technology under a contract with NASA. Support for this work was provided by NASA through an award issued by JPL/Caltech.
