  1. Chandra Users’ CommitteeCXC Manager’s Status ReportFor the period October 2012 – September 2013 Roger Brissenden CXC Manager 22 October 2013

  2. Topics • Program Management • Mission Operations • Spacecraft • Science Instruments and Calibration • Mission Planning • Operations Control Center • Science Operations • CXC Data Systems • Calibration • Data Processing • Chandra Director’s Office • GO Program • Einstein Program • Education and Public Outreach CXC Status Report/CUC

  3. Top Level Summary Spacecraft and instruments are performing superbly Fine Sun Sensor (FSS) was swapped to B (redundant) side to mitigate reduced A-side field of view Momentum Unloading and Propulsion System (MUPS) was swapped to B side to allow use of A side in event of a safe mode MUPS-B2 thruster will not be used due to zero thrust There are no known spacecraft limitations due to degradation, aging or consumables that would prevent our meeting Level 1 requirements over the course of a 20-year mission Preparing for 2014 NASA Senior Review Chandra and Hubble to have individual non-competitive reviews CXC Status Report/CUC

  4. Program Management CXC Status Report/CUC

  5. Program Management • Contract • Contract (Option 1) currently runs through 30 Sept 2016 • Option 2 available through 30 Sept 2019 • Budget • CXC is funded through December 16 • CXC’s budget and expenditures are consistent with the current plan • Directed to conduct EPO program in FY14 • Awaiting FY14 funding guidelines from HQ • Staff • Current staffing profile is consistent with plan • 3 positions were eliminated in 2013 (staff members left, will not be replaced) • All remaining positions are filled • Other • Complying with NASA travel restrictions, which have reduced CXC travel and increased administrative burden at CXC and MSFC CXC Status Report/CUC CXC Status Report/CUC Page 5

  6. Program Management • CXC-organized Conferences and Reviews • Chandra Peer Review (18-20 June 13) Boston • CXC Users’ Committee (22-23 Oct 13) at CfA • Einstein Fellows Symposium (29-30 Oct 13) at CfA • Considering 15 Years of Science with Chandra symposium – fall ‘14 CXC Status Report/CUC

  7. Spacecraft Continues to operate extremely well Nominal passages through eclipse seasons Swapped to Fine Sun Sensor B and MUPS side B Science Instruments Instruments are operating extremely well ACIS flight software triggered its first solar radiation safety action (5/22) Operations Control Center Smooth operations OCC air conditioning system upgrade was completed June 2013 Virtual OCC data system transitioned to operations 24 July 13 Mission Planning 6 fast-turnaround (load interrupting) TOOs during this period Observing efficiency is ~80% maximum due to orbit evolution Mission Operations CXC Status Report/CUC CXC Status Report/CUC Page 7

  12. Science Operations • Data Processing • Automatic processing is current; mean time from end of observation to delivery to user remains at about one day • Calibration • Products released since October 2012 • Set of ACIS blank sky observations appropriate for observations since September 2009 • Set of time-dependent ACIS quantum efficiency maps • Gain maps for ACIS (quarterly) and HRC (annual) • HRC-S QE map for data taken with the new HV setting • Products to be released by December 2013 • Update to ACIS contamination model • Improved low energy (<500 eV) gains for ACIS CXC Status Report/CUC Page 12

  13. Science Operations Data Delivery Avg delivery ~1 day from observation CXC Status Report/CUC
