  1. Chandra Users’ CommitteeCXC Manager’s Status ReportFor the period April 09 – October 09 Edward Mattison CXC Deputy Manager 29 October 2009

  2. Topics • Program Level Status • Program Management • Spacecraft • Science Instruments and Calibration • Mission Planning • OCC • Data Processing • CXCDS • Chandra Director’s Office • Education and Public Outreach • Mission Metrics • Chandra Grant Awards CXC Status Report/CUC

  3. Top Level Summary • Spacecraft and instruments are performing superbly • The CXC contract extension for up to 10 additional years and $573M is expected to be signed in mid-November CXC Status Report/CUC

  4. Program Level Status – Program Management • Budget • The CXC’s budget is on track with the FY09 Operating Plan • CXC contract extension • SAO submitted (in July) the requested proposal to extend the CXC contract for up to 10 years • We are currently working with MSFC and subcontractors to resolve audit questions and to deal with NGST rate changes that resulted from NGST’s corporate reorganization • Expect signed contract extension in mid-November CXC Status Report/CUC

  5. Program Level Status – Program Management • Facilities • SAO and NGST studied the feasibility of moving the OCC from Kendall Square to Cambridge Discovery Park, to save ~$1M/yr • Produced detailed plan and schedule • After considering benefits vs. risk, MSFC declined to approved the move • Reviews and Conferences • Peer Review (6/22/09) • Supernova Remnant workshop (7/8/09) • Quarterly review (9/2/09) • Calibration review (9/21/09) • Chandra’s First Decade of Discovery (9/22-25/09) • Einstein Fellows Symposium (10/27/09) CXC Status Report/CUC

  6. Program Level Status – CXC Organization CXC Status Report/CUC

  7. Program Level Status – Operations • Spacecraft • Continues to operate extremely well overall • Nominal passages through summer eclipse season • Science Instruments • Instruments are operating extremely well CXC Status Report/CUC

  8. Program Level Status – Operations • Anomalies • Momentum Unloading Propulsion System (MUPS) pressure drop • Propellant pressure reading decreased abruptly 7/19 • Cause: Pressure transducer operates incorrectly • Impact: Benign; Demonstrated CXC’s skill in handling anomaly situation • Grating status switch operates unexpectedly • HETG move flag set to ‘failed’ 7/7/09 (grating move was okay) • Cause: Previously-failed microswitch unexpectedly came to life • Impact: Benign; Updated software to ignore switch state • Incorrect command sequence uploaded • Cause: Operator error 8/28 • Impact: Benign (but could have led to safing action if not identified); Updated procedures to prevent recurrence CXC Status Report/CUC

  9. Program Level Status – Operations • Mission Planning: Load-interrupting TOOs • No load-interrupting TOOs during this period • Several loads were replanned to respond to anomalous conditions • Data Processing • Automatic processing is current; mean time from end of observation to delivery to user remains at about one day CXC Status Report/CUC

  10. Program Level Status – Operations • CXC Data System Releases Version Date Main contents DS 7.6.11.13 4/24 CfP11 proposal review support DS 8.0 7/14 Migrate operations to Solaris 10 DS 8.1 9/16 Migrate CDO, mission planning operations to Linux CIAO 4.1.2 4/20 Port to Solaris 10; release Level 3 tools CAT 3.1.2 5/21 CSCview, novice user fixes, VO cone search GoogleEarth1.0 6/26 Web interface to CSC field of view & images CAT 3.1.4 9/18 VO cone search verbosity fix CSC = Chandra Source Catalog VO = Virtual Observatory CXC Status Report/CUC

  11. Program Level Status – Operations • Calibration Database (CalDB) Releases • CalDB 4.1.3 7/7 ACIS T-gain epoch 37 • CalDB 4.1.4 9/17 ACIS T-gain epoch 38 • GO and Fellows Program, CXC Director’s Office • GO peer review 6/22; 668 proposals submitted, 207 approved • Einstein Fellows call for proposal posted; proposals due 11/5 • Grant issuance is current; average time to award < 3 weeks • Education and Public Outreach • CXC’s “Beautiful Universe” HD podcast series won the Communicator Award of Excellence, the professional peer-judged award by the same group that oversees the Webbys • “From Earth to the Universe, ” the International Year of Astronomy exhibit developed by the CXC’s EPO group, has been exhibited in over 200 locations in 65 countries, including close to 40 installations in a variety of settings in the US.
