Director’s Discretionary Early Release Science Programs

To realize the James Webb Space Telescope’s full science potential, it is imperative that the science community quickly learns to use its instruments and capabilities. To get the community up to speed, STScI and the JWST Advisory Committee developed the Director’s Discretionary-Early Release Science (DD-ERS) program.

The DD-ERS observations will take place during the first 5 months of JWST science operations, following the 6-month commissioning period. The program selections were made in November 2017 and represent six science categories.
