SC Composite Transfer to Mars (incl. EDL Prep.) Overview – 3 Operational top-level “Phases” SC Composite Transfer to Mars (incl. EDL Prep.) Platform Ops: Egress Support, Handover Relay Coordination Jan 2019 Jan-Sep 2019 (+) May 2018 – Jan 2019

EXM 2018 Ops Responsibilities – Assumptions (to be agreed by all parties) Before Launch  Mars Arrival SCC Transfer: ESOC responsible, with single interface to Industry to be established (TBC) EDL: Industry responsible for definition and validation of SW and sequence of events (like EXM2016) - including delivery of validated in-flight updates to ESOC for uplink Rover: ROCC responsible for Checkout; ESOC provides access SP Payload/Systems: SPOCC responsible for Checkout; ESOC provides access After Mars Arrival (Rover/SP Operations on Surface) Rover Ops performed by ROCC, with supervision by ESA , located in ROCC SP early ops (ending with Rover egress) ESOC responsible for SP operations needed for Rover egress; SPOCC responsible for minimum set of science ops (if any?) SP operations during science phase by Surface Platform Operations Center (SPOCC)

Stations and Space Communications Space-Ground interfaces Request for Frequency Assignment (RFA) - Draft + Space-Ground SGIRD available SCC SGICD Vol.1 to be written (with Industry); Vol. 2 available ROSCOSMOS 64m Station Bear Lakes in baseline to complement ESTRACK Full support (downlink, uplink, ranging/Doppler) for all phases EXM 2018 requirements: doc available, under discussion Finalise and define plan of works;  Define combined Usage Profile ESTRACK + Russian Stations. Transfer to Mars ESTRACK Malarguë 3 * 4h / week + (non-critical ops) ; longer, daily, + Cebreros / New Norcia for SCC critical phases (LEOP, Mars Approach) ROS 64m (routine +critical): for unfavourable conditions, but not only  Schedule of support TBD Entry Descent and Landing (EDL) Visibility of Earth at Arrival time  Search for UHF radio telescope once time known Monitor via TGO, reuse for EXM2018 DM arrival the Electra Open Loop tool [EXM2016] Relay at Mars – current Rover Ops Concept requires ESTRACK (1 pass/day): covered by existing [EXM2016] TGO plans Plus ROS 64m Relay 1 pass/day with [EXM2016] TGO

High-level Preparation Schedule  Possibly to be adapted wrt Industrial Schedule and ESA-level reviews

Operations Preparation MIRD / MIP (Project ↔ ESOC) Ops Interface Requirements OIRD baseline available Mission Implementation Requirements (MIRD) – Close to signature TBW: Mission Implementation Plan MIP Flight Control Team (FCT) - Key Activities Secured resources for Ops Engineering and Ops Management to build the FCT  To be started : Flight Operations Plan (FOP): + Ops Spacecraft Database (from Industry inputs) TBW: User requirements + User acceptance for MOC systems Validation on SCC Hardware and Software: to be defined PFM: System Validation Tests SVTs Preceded + complemented by tests MOC ↔ Avionics Test Bench Ground Station Preparation ESTrack Validation Assistance to ROS 64m validation

Mission Analysis, Flight Dynamics, MOC Systems Mission Analysis Guidelines available + ad hoc studies on going  Consolidated Report on Mission Analysis (CREMA) - TBW Flight Dynamics  Requirements to be started for EXM2018 specifics, from Industry SCC User Manual Mìssion Control System (MCS) Requirements to be started: ESOC S2K infra (EXM2016) + EXM2018 customization System Simulator (Sim) Procedure validation, Team training for Cruise, EDL (upload verif), Surface Egress Requirements TBW : ESOC infrastructure, plus EXM2018 (OBC, attitude control) MOC Hardware and Facilities Computers  maximize commonality with EXM2016 Control Room, shared, already existing.  Proximity to EXM2016 MOC and ERCO ROCC-provided mini-system at ESOC (for major ROCC issue)  Integrate and Test

European Relay Coordination Office ERCO (@ ESOC) - Roles RELAY Ops Coordination (in preparation via [EXM2016]) Planning and Execution of all landed assets Ensure redundancy and 7/7 manning for critical ops and on-surface prime relay phase  Plan ahead TGO relay for ROV + SP ROVER and ROCC Ops: (In-flight) Check-out of Rover Cooperation SCC MOC (+ERCO) with ALTEC / ROCC for Egress Ops  Setup / responsibility lines to be consolidated between ESA, TAS-I, ROCC Surface Platform and SPOCC Ops: (In-flight) Check-out of Science payload Cooperation SCC MOC (+ERCO) with ROS / SPOCC for early SP ops and Handover  Define ROS Involvement in early SP operations and Handover + define Handover

European Relay Coordination Office ERCO – System and Ops Interfaces Mission Control System from [EXM2016] for data / cmds relayed via TGO Standard interface? Mission Planning System: Relay Planning Tool and central database of overflights, to support European + Russian assets with TGO independently of NASA tool Specific “Relay MPS“ Interfaces with ROCC / Rover: MOC/ERCO-ROCC IRD - baseline available Interplanetary Transfer: check-out (via file, as per relay ops) On Surface: via SP (before Egress) or from TGO. Interfaces with SPOCC / Surface Platform: Similar to ROCC TBW: MOC/ERCO - SPOCC Interface Agreement Define Responsibilities, reqts, database, procedures, validation Interplanetary Transfer: check-out (via file) On Surface: TBD depending on design (OBC-1 /OBC-2)

Conclusions – Items Critical To Success For Launch (and beyond) Ground Segment development very compressed schedule for 2018 Launch Complex reqts archiecture on a network of flight and ground assets. 4 Ops centres. Validation: “end-to-end” testing of a multi-spacecraft/multi-centre system Russian station (with ESTRACK) key to mission For EDL DM preparation responsibilities share/split with Industry For Science and Relay Routine Cooperation and coordination between several ground segments ESA/ESOC hands over Surface Platform to ROS at end of Rover egress Relay of multi-agency multiple assets
