James Webb Space Telescope
Advisory Committee

In 2009, STScI director Matt Mountain appointed the JWST Advisory Committee (JSTAC) to advise the STScI on the Institute's readiness to support science operations with JWST, the implementation of NASA's science policies, and other matters related to the general observer program. Garth Illingworth is the JSTAC Chair. We provide links below to the JSTAC charter and membership. Garth and the members of the JSTAC would welcome comments and concerns from future Webb observers.

April 2014 Update

A presentation was made by the Chair of the JWST Advisory Committee (JSTAC), Garth Illingworth, at the JWST Science Working Group meeting on April 01st, 2014. The presentation was focused on the JSTAC's recommendations for maximizing the science reward from JWST. It included a discussion of JWST's Early Release Science Program, Community Fields, and recommendation for shorter default proprietary time on all JWST GO observations. The foot note with ** on Slides 29 and 31 were added after the presentation, based on comments from the SWG.

A second presentation was given to the SWG by JSTAC member Lisa Storrie-Lombardi, on 'Science Planning for a Limited Lifetime Mission – Spitzer Experience'.

In addition to the presentation, two letters (see below) from the November 2013 JSTAC meeting summarize their recommendation on these topics.

Nov 2013: The 8th Meeeting of the James Webb Space Telescope Advisory Committee (JSTAC)

The JSTAC met at STScI on Nov 21-22nd 2013. During the meeting, the NASA HQ Acting Program Director, the GSFC Program Manager, and the Senior Project Scientist for JWST each presented updates on the Program budget, schedule, status, and Science Working Group activities. STScI also presented several talks on the status of community interaction initiatives, ongoing work on building data simulations, and the overall readiness of the Science and Operations Center. The Science Mission Office at STScI shared with the committee some ideas on JWST observing cycles, different types of potential proposal categories, and the Early Release Science program and asked the committee for advice on these topics.

A letter was submitted to the STScI Director by the JSTAC on March 31st, 2014 regarding the committee's recommendation for JWST Early Release Science and Community Fields.

A letter was submitted to the STScI Director by the JSTAC on March 31st, 2014 regarding the committee's recommendation for JWST proprietary period for GO observations.

July 2013 Update

A presentation was made by the Chair of the JWST Advisory Committee (JSTAC), Garth Illingworth, and JSTAC member Brad Peterson to the JWST Science Working Group on July 22nd, 2013. The presentation summarizes JSTAC recommendations for shorter proprietary time periods for JWST observations, to maximize the scientific return from the mission.

May 2013: The 7th Meeeting of the James Webb Space Telescope Advisory Committee (JSTAC)

The JSTAC met at STScI on May 08-09th 2013. The meeting included updates to the committee from NASA HQ, GSFC, and STScI, on the program status and budget, project science, status of the S&OC, and plans for JWST's early release science program and data analysis tools. There was also a discussion of JWST grant funding needs, proprietary time, and lessons learned from previous large missions.

A letter was submitted to the STScI Director by the JSTAC on July 28th, 2013, concerning the committee's recommendation for the level of GO funding during JWST science operations.

December 2012: The 6th meeting of the James Webb Space Telescope Advisory Committee (JSTAC)

The JSTAC met at STScI on Dec 10-11th 2012. Several presentations were given, including the status of STScI's readiness for science operations, proactive outreach strategies, SODRM update, and much more. Action items were collected for the next meeting, which will occur in May 2013.

May 2012: The 5th Meeting of the James Webb Space Telescope Advisory Committee (JSTAC)

A webex JSTAC meeting was held on May 18th to review the status of JWST. Presentations were given by NASA HQ, the STScI Directorate, and the JWST Mission Office at STScI.

February 2012 Update

This letter from the JSTAC was sent to Secretary Hillary Rodham Clinton, Secretary of State, U.S. Department of State and Dr. John P. Holdren, Director, Office of Science and Technology Policy, Executive Office of the President of the United States, and was copied to the cc list on page 3 of the letter.

June 1-2, 2011:The 4th Meeting of the James Webb Space Telescope Advisory Committee (JSTAC)

The JSTAC met at STScI on June 1 and 2 to review development status.

December 1-2, 2010: The 3rd Meeting of the James Webb Space Telescope Advisory Committee (JSTAC)

The 3rd meeting of the JSTAC was held at the STScI on Dec.1-2, 2010. The committee reviewed the recommendations of the ICRP report and NASA's response from Eric Smith and the new Project Manager, Bill Ochs. NASA and STScI scientists presented reports on the primary mirror development and outreach to the astronomical community.

May 27-28, 2010: The 2nd Meeting of the James Webb Space Telescope Advisory Committee (JSTAC)

The 2nd meeting of the JSTAC was held at the STScI on May 27-28, 2010. The committee reviewed the considerable progress in both the JWST Project and the SOC development since the meeting in November. It also considered ways to provide science data to the community early in mission in order to maximize Webb's lifetime productivity over its nominal lifetime.
