  1. Rosetta LanderSystem and ProgrammaticsBerndt Feuerbacher, DLR Cologne Payload Review 8-June-2000

  2. Overview • Project team reorganized in January 2000 • Joint Task Force established between Lander Team and ESA • Schedule reworked for EQM and FM • Team strength increased • Project resources increased • Close contact established within Lander team • FDIR analysis in progress

  3. Key System Contributions Rosetta Lander Team Instrument PIs • MPAe Lindau • MPE Garching • MPC Mainz • IAS Orsay • DLR Cologne • DLR Berlin • Open University Milton Keynes • KFKI Budapest • University Münster • LPG Grenoble • DLR Cologne • DLR Braunschweig • MPAe Lindau • MPE Garching • CNES Paris, Toulouse • ASI Roma • KFKI Budapest • STIL Dublin • FMI Helsinki • RAL Chilton • IWF Graz

  4. 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

  5. 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

  6. 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

  7. 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

  8. Payload Overview

  9. 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

  10. 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)

  11. Schedule Overview

  12. FM Milestone Development Subsystems (1)

  13. FM Milestone Development Subsystems (2)

  14. FM Milestone Development Payload (1)

  15. FM Milestone Development Payload (2)

  16. 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
