Jan-Sep 2019 (+)
May 2018 – Jan 2019

4. 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)

6. 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

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

8. 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

9. 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

10. 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
