• 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 3rd Chandra Flight Director (replaces Rob Cameron).
– Facilities: Draper Labs moving ahead with new Hill building attachment. ~1500 sf floor space to be lost to 7th 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.

• 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

• 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:

• 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
