25 January 2005CXC Status Report/CUCPage 3 Program Management –Successfully passed the 5 year milestone on July 23, 2004! –CXC remained within budget for FY04 and expect FY05 costs to track to POP04 plan. HRC, ACIS & HETG PI subcontracts moved under SAO, 1 Oct 04. –Staffing: Martin Elvis resigned as Lead for Science Data System Planning, Jonathon McDowell appointed new Lead with Mike Wise (MIT) as Deputy. –Tom Aldcroft certified as 3 rd Chandra Flight Director (replaces Rob Cameron). –Facilities: Draper Labs moving ahead with new Hill building attachment. ~1500 sf floor space to be lost to 7 th floor including the conference room and 5 offices. ACIS room to be sacrificed to allow for new conference room to be built. ACIS Equipment has been relocated to the TST room. Program Level Status 6/30/04 – 1/25/05

25 January 2005CXC Status Report/CUCPage 8 Spacecraft –Continues to operate extremely well overall –OBC patch for SCS 101 and SCS 31. Modify 101 to contain all CPE patches; modify 31 to call 101 during eclipse ops, 8/23. Improved eclipse safemode transition. –Helium Channel replacement patch, 9/1, for use of HRC anti-coincidence shield data in place of EPHIN as radiation detector. 6 cases of EPHIN rail voltage anomaly due to high temperatures however no indication of performance degradation; plan to budget ~6 rail voltage drops per year. –Conducted ACA dark current calibration 9/9 and 12/24 – shows expected trend in warm pixel increase –Nominal ’04 summer and ’05 winter eclipse seasons, nominal Lunar Eclipse, 11/12 –Radiation events during ’04 eclipse season resulted in contingency commanding and 3 Normal Sun Mode (NSM) recoveries. –Uneventful Leonids passage 11/19 –Anomalies: Propulsion line cooling, EPHIN rail voltage, unexpected NSM transition Program Level Status 6/30/04 – 1/25/05

25 January 2005CXC Status Report/CUCPage 9 Mission Planning –Thermal heating and constraints starting to impact mission planning –10 SCS 107 runs due to high radiation events (includes major event last week) –7 load interrupt TOOs: DateTargetRequest 07/05/04AXP day 08/14/04GRB days 08/31/04XRF days 09/13/04GRB days 10/06/04GRB days 10/06/04SGR days 12/13/04BL day Program Level Status 6/30/04 – 1/25/05

25 January 2005CXC Status Report/CUCPage 10 Science Instruments and Calibration –Operating extremely well overall –ACIS bakeout decision postponed in Sept due to safety concern over use of abort heaters, and simulation questions over contaminant volatility –HRC anticoincidence shield rates show acceptable correlation with high energy EPHIN channel. Antico rates exceeded proposed threshold for prior radiation safing event during mission, i.e., a safe EPHIN alternative –2004 Calibration Review held 10/25-10/26 OCC –Linux Migration initial config. 10/4, test started 12/1, to ops 3-4/05 –DSN unexpected commanding, 9/11 DateVersionChange 07/23/04OFLS 11.0Linux port 12/06/04ONLS Linux port; test fixes 12/06/04OFLS 11.3Linux port Program Level Status 6/30/04 – 1/25/05
