STScI Role in JWST• STScI is the Science and Operations Center for JWST. We will

manage the science program from observing program solicitation and selection to grants management and science outreach support.

• Operate JWST - beginning in commissioning• Develop the science and operations ground systems• Perform ground segment verification• Perform end to end testing• Scientific and Public outreach • Support the Project and JWST teams during the development phase:

– Mission architecture & system engineering– ISIM & Scientific instruments & ISIM flight software– Optics and wavefront sensing and control– Science and operations input to many working groups

Work to generate a set of simulated JWST images (spectra to follow) of different astrophysical systems (e.g., a globular cluster, a deep galaxy field). – These images can form “data challenges” to allow astronomers to work with expected JWST data and form analysis tools. – Simulated products will help evaluate STScI data reduction pipelines.

A Preliminary Example: An easy way to generate a simulated image

From ETCs to Simulated Images to next steps

Webb is not easy to use!

• Multi-object spectroscopy

• Coronography

Data Challenges

• Data Challenges would be part of the joint learning process: the community can become familiar with JWST data sets and at the same time members of the community might discover improved ways for dealing with the data.• The challenge will consist in carrying out one or more complex measurements on the simulated data.•First challenge: An imaging data challenge, probably aimed at a JWST deep field• The second challenge will be a spectroscopic challenge and might be based on NIRSpec Micro-Shutter Assembly data or MIRI Integral Field Unit data.

MIRI IFU ground test data at 5.7-6.7 m and 8.7-10.3 m

If possible one could imagine additional challenges on, e.g. coronagraphs or transits.

Some JWST Working groups at STScI

ETC (E. Barker) : developed the prototype ETC.

Efficiency (K. Gordon) : monitoring predicted observing efficiency for JWST, suggest improvements, maintain DRM.

Coronography (R. Soummer): study operational strategies for JWST coronographs.

Cross-mission (HST-JWST) WGs

Slitless Grism : transfer experience from HST to JWST. Held conference

IR Detector Persistence : draw operational lessons for JWST from HST experience. Established WFC3/IR and JWST detectors behave differently.

Photometry : establish limiting factors to photometric accuracy and develop paths for improvement

User support and documentation : future trends in user support.

JWST Public OutreachThe E/PO program must train educators and raise public awareness

about JWST’s unique scientific role in our understanding of the Universe

E/PO tools and exposures (STScI, GSFC, NGAS, CSA, and ESA)- News releases and media- printed materials- videos and 3D content- animations- dedicated websites- social media- blogs- exhibits and support materials (e.g., recent World Science Festival in NYC)- hard-copy and web-based curriculum support- professional development programming

Online and hard-copy materials are:

Used in all 50 states.Used in 42 of the 100 largest school districts in the country.Reach an estimated 6.3 million students per year.Reach an estimated 506,000 pre- and in-service teachers.

Webb’s outreach and education program will build upon Hubble’s success
