Deep Space Network (DSN) Readiness

• DSMS Level 1 Support Requirement Summary
• Criticality level 1 Per DSMS 841-001 Document
• Significant one of a kind events such as
  launches, encounters, and unique scientific
  events. A ground system failure could
  jeopardize the spacecraft, result in loss of
  unique scientific data, or result in the failure
  to achieve one or more mission objectives. The
  DSN is at its highest level of mission readiness
  when in the Level 1 posture.
• DSMS Level 1 Support Times
• TCM-12
• December 31/365-1500 through December 31/365-2100
  
• TCM-13, TCM-14/Final Update/ Encounter
• January 2/002-0100 through January 3/003-0100

Deep Space Network (DSN) Readiness

• DSMS New Implementations
• DSS 55 in Madrid, which is a 34-meter Beam Wave
  Guide was declared operational 1 November
• Stardust participated in successful Demonstration
  passes prior to operational date
• DSS 55 being used routinely by other mission on a
  daily basis since 1 November
• No issue or concerns with DSS-55 support
  capabilities
• Other
• Alternate Assets (New Norcia/Parkes) does not
  benefit Stardust and is not planned
• DSMS array does not benefit Stardust and is not
  planned
• Goldstone Emergency Control Center (ECC) does not
  benefit Stardust and will not be used

Deep Space Network (DSN) Readiness

• DSMS Triage
• DSMS Triage Plan (DSMS 802-009) issued Oct 29
  2003
• Stardust has participated in several DSMS work
  shops in which several triage scenarios where
  worked
• DSMS Triage Plan augments the existing Standard
  Operations Plan for the Deep Space Network (DSM
  841-001)
• DSMS Triage Plan provides special DSMS War Room
  
• JPL DSN Mission Event Readiness Review (MERR)
  held on 13 November 2003
• Held 3 weeks earlier then standard (event minus
  30 days)
• 1 Advisory written, No Request For Actions (RFAs)
• Review Board complimented Project on the
  robustness of mission planning for the encounter
• Review Board consensus was that the DSN is
  prepared and ready to support the Wild II
  encounter
