SPHEREx Data Release 1 (DR1) Spectral Images

SPHEREx is a NASA Astrophysics Medium Explorer mission that launched in March 2025. During its planned two-year mission, SPHEREx will obtain 0.75-5 micron spectroscopy over the entire sky, with deeper data in the SPHEREx Deep Fields. IRSA will release new SPHEREx Quick Release Spectral Images on a weekly basis, with additional releases of higher-level data products planned over the three years following launch.

IRSA released SPHEREx Data Release 1 (DR1) in November 2026. DR1 includes reprocessed versions of the QR2 spectral images. The DR1 spectral images are intended to be used together with the QR3 spectral images as a uniformly processed set.

This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.
