Program Level Status – Program Management • Budget and Contract • The CXC’s budget is on track with the FY09 Operating Plan • Program budget guidelines for FY10-14 have been released by NASA HQ and we assessing them for impacts. Meeting with HQ 4/13/09 • NASA has issued a request for proposal for a CXC contract extension to continue Chandra operations and science for up 9 additional years • A fast-track Integrated Acquisition Team approach is being used: the IAT held its first meeting on 3/10/09 • RFPs to SAO subcontractors have been issued, with 45 day turnaround • Proposal is planned for submission by May 15 with start date 10/1/09 CXC Status Report/CUC

4. Program Level Status – Program Management • Facilities • The OCC’s contingency computer system at the CfA’s Cambridge Discovery Park facility has been tested with the spacecraft and been shown to be capable of supporting mission operations in case of a serious interruption to the OCC. • Reviews and Conferences • CIAO workshop (10/20/08) • Chandra Users’ Committee (10/15/08) Planned: • Peer Review (6/22/09) • Supernova Remnant workshop (7/8/09) • Calibration review (9/21/09) • 10 Years of Science with Chandra (9/22-25/09) CXC Status Report/CUC

6. Program Level Status – Operations • Spacecraft • Continues to operate extremely well overall. • Transition to Normal Sun Mode (10/21/08) due to a single event upset in a circuit known to be susceptible to SEUs. 168 ks of science lost. No adverse impact to mission. • Nominal passages through summer eclipse season, 6/12 – 7/6. • Science Instruments • Instruments are operating extremely well. • ACIS flight software v.44 performing nominally • Upload of v.44 on 10/1/08 coincided closely with ACIS watchdog timer reboot in continuous clocking mode • Reloaded v.31 10/6/08 and started long test of v.44 in CC mode • Reloaded v.44 on 1/15/09; nominal performance since CXC Status Report/CUC

Landlord has taken mitigating measures • Data Processing • Automatic processing is current; mean time from end of observation to delivery to user remains at about one day “Please pass on to the relevant groups my appreciation and congratulations on a smoothly running system! My M87 observation ended circa 5am EDT 1 Apr. The data were made available to me in the evening, and I reduced them before going to bed... all in the same day. cheers, Dan [Harris]” CXC Status Report/CUC
