NEOWISE Reactivation Data - Near-Earth Object Infrared Survey
Catalog Summary
"Infrared survey data from the reactivated NEOWISE mission with >20 million calibrated FITS images in two bands (W1, W2). Essential for asteroid and comet discovery and thermal modeling."
Catalog Notes
Overview
The NEOWISE Reactivation dataset contains infrared observations from the reactivated phase of the WISE spacecraft, repurposed to hunt for near‑Earth objects (NEOs) such as asteroids and comets. It provides annually updated survey data for planetary defense and small-body science.
Data Contents
- More than 20 million calibrated FITS image sets from individual ~7.7-second NEOWISE survey exposures.
- Two mid-infrared bands: W1 (3.4 μm) and W2 (4.6 μm).
- Associated catalogs with detections, astrometric solutions, and photometry.
Use Cases
- NEO discovery and orbit refinement.
- Thermal modeling to estimate asteroid diameters and albedos.
- Population studies of main-belt asteroids and comets.
- Training ML pipelines for moving-object detection in time-domain surveys.
Access
The dataset is hosted via the AWS Open Data Registry, allowing large-scale mining of multi-year NEOWISE observations without local storage limitations.
