• 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.

• 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.

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.
