The Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) and IPAC at the California Institute of Technology announce the NEOWISE 2023 Data Release.
The 2023 Data Release includes data acquired during the ninth year of the NEOWISE Reactivation mission (Mainzer et al. 2014), from 13 December 2021 to 13 December 2022. These data are combined with the year 1-8 data into a single archive that contains ~22.9 million sets of 3.4 and 4.6-micron images and a database of ~171 billion source detections extracted from those images.
NEOWISE scanned the sky nearly 18 complete times during the first nine years of survey operations, with approximately six months between survey passes. Twelve or more independent exposures are made on each point of the sky during each survey epoch, making the NEOWISE archive a time-domain resource for extracting multiple, independent thermal flux and position measurements of solar system small bodies and background galactic and extragalactic sources.
See the guide to the NEOWISE data release, data access instructions, and supporting documentation. Access to the NEOWISE data products is available via the online and API services of the NASA/IPAC Infrared Science Archive (IRSA).
NEOWISE is a joint project of the Jet Propulsion Laboratory/California Institute of Technology and the University of Arizona, funded by NASA’s Planetary Defense Coordination Office.
