Program Level Status

• Program Management

• Budget: The CXC’s budget is unchanged from the current Program Operating Plan (POP07, submitted Oct 07), and expenditures are on track to meet the budget. We presented POP08 to NASA headquarters on 3/28/08.
• Senior Review: The proposal for the Senior Review of the Chandra Program was submitted to NASA on 3/12/08. A presentation to the review board will be given on 4/23/08.
• Staffing: Staff numbers remain near FY06 levels, as planned. Sabina Bucher has been appointed Flight Operations Team manager to replace Dan Shropshire. Ms. Bucher, who has been with the FOT for 8 years, was previously a mission planner and a propulsion engineer, and most recently the Mission Planning manager.
• Facilities: The OCC’s backup computer system, which has been installed in the CfA’s Cambridge Discovery Park facility, is being configured for test and will be operational in summer 08. The OCC’s operations areas and common spaces are being painted and renovated.

Program Level Status

• Spacecraft

• Continues to operate extremely well overall
• No spacecraft anomalies during this period
• Nominal passages through winter eclipse season, 12/21/07 – 1/3/08, and two lunar eclipses, 10/10/07 and 2/6/08

• Science Instruments

• Instruments are operating extremely well.
• The HRC +Y Shutter was used successfully in an observation of the Crab Pulsar to reduce the event rate below telemetry saturation in order to enable high-precision timing.
• Tests of turning off the ACIS detector housing heater were successful and the Flight Directors’ Board has approved turning off the heater permanently, as early as 4/7. This action should result in a higher fraction of ACIS observations having a cold and stable focal plane temperature.

Program Level Status

• Mission Planning – load-interrupting TOOs

• Accepted Target Time*
• 09/20/07 SGR 1806-20 4d 20h
• 10/10/07 H 2356-309 0d 20h

• 01/14/08 NGC2770/SN2007uy 5d 11h
• 02/10/08 GRB 080207 5d 14h
• 02/15/08 4U1812-12 2d 11h
• *Time from TOO approval to start of observation

• OCC

• Following an extensive security audit, the OCC received the formal Authority to Operate from NASA on 9/17/07.
• The OCC Data System and GRETA networks have been migrated to a NetApp storage cluster for increased reliability.

Program Level Status

• Data Processing

• Automatic processing is current; time from end of observation to delivery to user remains at about one day (median increased slightly during this period due to a few difficult-to-process observations of Venus)
• Data reprocessing (Repro 3) was completed 11/05/07. 514 HRC-I observations were reprocessed to apply new calibrations (completed 11/26/07), and reprocessing of an additional 157 observations to apply observation parameter corrections is in preparation.
