NEOWISE 2024 Data Release

The Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) and IPAC at the California Institute of Technology announce the NEOWISE 2024 Data Release.

The 2024 Data Release includes data acquired during the tenth year of the NEOWISE Reactivation mission (Mainzer et al. 2014, ApJ, 792, 30), 13 December 2022 to 13 December 2023.  These data are combined with the Year 1-9 data into a single archive that contains ~25.3 million sets of 3.4 and 4.6 micron images and a database of ~189 billion source detections extracted from those images.

NEOWISE scanned the sky nearly twenty complete times during the first ten 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.

A guide to the NEOWISE data release, data access instructions, and supporting documentation are available at  Access to the NEOWISE data products is available via the on-line and API services of the NASA/IPAC Infrared Science Archive (IRSA) at

NEOWISE is a joint project of the Jet Propulsion Laboratory/California Institute of Technology and the University of Arizona, funded by the National Aeronautics and Space Administration Planetary Science Division.
