Presentation Transcript

  1. Mission Engineering and Science Analysis (MESA) What is MESA? Jeff Valenti

  2. 2012 Instruments Division Reorganization Cross Mission JWST RIAB RIAB HST TEL TEL WIT MESA NIRCam NIRSpec COS/STIS COS/STIS NIRISS ACS ACS MIRI WFC3 WFC3 before after “WIT split” We still use “WIT” to refer to JWST teams + MESA (+ TEL)

  3. Purpose of MESA • Home of Instrument Engineers • Home of Operations Detector Lab (ODL) • Cross-instrument experiments and analysis • Encourage cross-instrument consistency • Build on foundation established by WIT • Coordinate WIT working groups • Facilitate communication between scientists iand engineers at STScI

  4. MESA Originally Included Instrument Engineers Tom Wheeler Chris Long Dave Hickey Audrey DiFelice John Bacinski HST ENG JWST ODL Moved to new Flight Operations Branch (FOB) Steve Vaclavik, Wayne Baggett, Ray Wright, ...

  5. Mike MESA Eddie Bergeron Lou Strolger Rachel Anderson (MIRI) Rossy Diaz HST ODL Van Dixon (NIRISS) JWST Doug Long Brian York (HST) Bill Blair Harry (SMO)

  6. Customary to show a picture of the instrument... SM 2 SM 1 MESA “Instrument”

  7. And the important components inside...

  8. WIT Working Group Concept • Participants • Representative from each WIT instrument group • Lead from WIT, not necessarily MESA • Engineers, once science concept is formulated • Nominal process (still evolving) • WG scientists meet and converge on science concept • WG solicits comments from engineers and entire WIT • WG lead finalizes recommendations • Engineers develop engineering concept • WG meets with engineers to finalize unified concept • Engineers generate requirements/PRs

  9. WIT Working Group Domains Coronagraphy, Backgrounds, Exoplanets, ...

  10. WIT Working Group Scientists https://confluence.stsci.edu/display/JWST/MESA+Working+Groups

  11. What about Hubble? • HST work in MESA • ETC, CDBS/CRDS [Rossy] • WFC3 pipeline, HLA source catalogs [Lou] • Cross-Instrument working groups • Astrodrizzle • Enhanced spectroscopy products [Alessandra] • Astrometry? • Cross-Mission Projects • CDBS  CRDS (reference files/data) • OPUS  OWL (workflow manager based on Condor) • Define system based on JWST needs and new technology • Implement first for HST, retire risks for JWST deployment
