Welcome to the JWST FRESCO Survey

FRESCO stands for the "First Reionization Epoch Spectroscopically Complete Observations" - a JWST cycle 1 program of about 54 hours to obtain deep NIRCam/grism spectra over the two GOODS legacy survey fields.

To ensure these legacy data are fully exploited, we will release high-level science data products to the community as soon as they are available, which will be announced on this webpage.

The observations were taken Nov 2022 and Feb 2023. The full raw data from our program is public immediately and can be downloaded from the STScI MAST archive.

More detailed information on the FRESCO survey can also be found in the survey paper Oesch et al. (2023).
