CXC Managers Status Report

• Chandra User Committee Meeting
• Roger J. Brissenden
• 25 June 2002

Program Level Status

• Spacecraft continues to perform superbly and
  operations continue to be routine. No significant
  spacecraft hardware problems or safe modes have
  occurred since last report.
• Flight software patch to mitigate EPHIN hardware
  failure flag glitch running SCS 107.
• 827 Cycle 4 proposals (817 GO, 10 GTO) submitted
  by deadline of 3/15/02. Peer Review held on
  schedule June 18-20.
• Plan agreed to with MSFC and HQ on adding
  resources in the Ed/Outreach area to provide
  additional emphasis on SSUs.
• CXC Quarterly review 4/23/02. No major actions
  resulted from the review. MSFC Independent Annual
  Review to be held 9/5/02.
• Contract change in work to direct SAO to perform
  call for proposals in place of NRA similar to
  HST model.
• CXC Contract extension proposal for 11-months
  from 9/30/02 to 8/31/03 in final sign-off with
  MSFC.
• MSFC is pursuing a JOFOC approach for contract
  post 8/31/03. Second 5-year budget level briefing
  given to HQ as part of POP-02.
• No significant near-team budget or staffing
  issues. Out-year profile in work with HQ.

Items from January 02 CUC

• Occasionally a few datasets are delivered well
  beyond the mean lag of 7 days. We suggest that
  each OBSID has a built-in alarm so that the
  appropriate scientists are informed when an OBSID
  has been unduly delayed.
• The archive group has installed a script which
  checks the automated processing (AP) status for
  observations which have been in the queue for a
  week or more. The duty scientist is notified of
  all such observations. In addition DS has
  implemented monthly manual checks of the AP
  status tables for observations which have been
  received but for which processing has not
  completed.
• We recommend that more channels be opened by
  which either the Director or the CXC Outreach
  office can learn of potentially interesting
  results. Possibilities include charging CUC
  members to take some responsibility for
  identifying potentially appropriate science
  results and sensitizing PIs of successful large
  proposals of this issue.
• The CXC has reached agreement on a plan with
  MSFC and HQ to increase the resources in the
  Education and Public Outreach area. An important
  task for the new resources will be to address
  this issue.

Operations

• Nominal Spring 2002 eclipse season.
• Patch up-linked to increase glitch counters and
  mitigate EPHIN hardware failure glitch counter
  trips of SCS 107 (second occurrence on 4/2/02
  however EPHIN hardware is nominal and cause
  traced to subtle timing condition).
• Successful test of bright earth constraint
  limitation. Expected to lead to reduction of the
  20 degree constraint yielding more flexible
  scheduling.
• 6 executions of SCS 107 due to high solar
  activity, 1 assessed as due to EPHIN hardware
  failure glitch.
• No ACIS CTI degradation above expectations.
• Anomalies
• None.
• Hosted a number of visits or discussions with
  other mission teams
• NGST, SIRTF, Kepler, SIM, HST (July).
