Title
SPHEREx Quick Release Spectral Images - QR2
Description
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. SPHEREx Quick Release Spectral Images are Level 2 calibrated data products released on a weekly basis throughout the SPHEREx mission.
IRSA began releasing SPHEREx spectral image data on a weekly basis in July 2025 (Quick Release 1; QR1). In October 2025, IRSA began distributing SPHEREx spectral image data processed with substantially improved calibrations. This new processing, referred to as QR2, includes reprocessed versions of all spectral image data acquired since the start of the mission. Future quick releases will also use the QR2 pipeline. IRSA will continue to provide access to QR1 data for reference. However, QR2 supersedes QR1 and will be the default returned in the SPHEREx Data Explorer and by all IRSA program-friendly APIs. QR1 data will remain available only through browsable directory listings.
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.
