joint task force
Joint Task Force
  • Established Jan 2000 on behalf of Executive Managenment Committee
  • Mandate:
    • consolidate mission, system and operations issues
    • consolidate schedule
    • assessment 3 months, implementation 3 months
  • Members from Lander Team and ESA
  • Results
    • mission assessment completed, implementation in progress
    • schedule delay reduced
    • many technical, financial and schedule issues resolved
    • close cooperation Lander Team - ESA established
project resources
Project Resources
  • New management structure established Jan 2000
  • Staffing increased, all vacancies filled
  • Resources increased through efforts of
    • DLR
    • CNES
    • ESA
  • Flywheel and ESS Software contracted to industry
  • Two integration teams formed (DLR, MPAe) for parallel work on EQM, FM
subsystem status
Subsystem Status
  • Structure & Thermal
    • STM qualified, EQM delivered, FM on track
  • Power
    • PCU: EQM integrated and tested, FM integration starts with EQM-2, exchange for FM Dec 2000, schedule critical, progress is shadowed
    • Solar generator: FM cells delivered, integration in progress
    • battery capacity upgrade agreed
  • CDMS
    • EQM integrated and tested, FM on track
    • Software: progress satisfactory, staff reinforcement established
  • Descent system
    • ADS: EQM on track, FM delayed due to components delivery, no impact on overall FM schedule
    • Flywheel:contract signed, FM in production
subsystem status ii
Subsystem Status II
  • Anchor - on track
  • Landing Gear
    • FM and DM schedule agreed
    • detailed design in certain areas incomplete
    • qualification parallel to FM integration
  • Orbiter-Lander interface
    • TxRx: EQM integrated and tested, FM on track
    • ESS: FM software contracted to industry, hardware progress slow , development shadowed
    • MSS: on track
  • STM separation tests successfully completed
  • Sample retrieval and distribution
    • Drill EQM integrated, FM on track
operations
Operations
  • Lander delivery at 3 AU
  • Science operations consists of
    • initial science sequence
    • long term operations
  • timeline for initial science (65h) supported by battery
    • energy margin critical
    • increase of battery enhances robustness
  • extended operations timeline supported by solar generator + secondary battery
aiv status
AIV Status
  • EQM delivery and integration complete except for
    • CIVA-CE, CIVA/M, CASSE, DIM, PP (LG-Foot)
    • Outstanding activities:
      • CDMS S/W update
      • Integration and Integrated Unit Tests of above mentioned units
      • Integrated Unit Tests for SD2, ADS
      • Final MLI and harness work
    • Tests to be performed prior to EQM delivery to ESA:
      • Integrated System Tests, partially with EMC testing on integrated unit level (June / July 00)
      • End-to-end Test with ESS + MSS (June / July 00)
      • Lander Level EMC Qualification Tests (August 00)
conclusions
Conclusions
  • Project consolidation process proceeds satisfactory
  • Lander status as Orbiter subsystem implemented
  • Joint Task Force works efficient and successful
  • Coordination within Lander team improved
  • Shadow engineering implemented for critical subsystems / payloads
  • Schedule incompatibility minimized, based on testing opportunities after delivery
  • Project remains fragile, but all partners combine efforts to ensure success
