Rover Operations Concept ROCC is integrating the Science Operations Centre (SOC) and is fully responsible to all the commands sent to the Rover and its instruments. The commands are generated as a result of the planning process. Strategic Planning Prepare the coming plans (e.g. where to go next). Refine the coming sols plans . Tactical Planning Refine the (up to two sols) Activity Plans for upload to the Rover including alternative activities. Scientists at ROCC and supported remotely by their home base. Timely provide the scientific assessments of the data supporting the strategic and tactical planning -> ROCC to PPL ICDs discussion Fundamental: Assessments and data are shared within the ROCC (ref to Rules of the Road) Scientific Archives are prepared at ROCC and sent regularly to ESAC-PSA.

Rover Module operations per phase   ExoMars Rover Operating Scenarios Transition Pre-Launch through Interplanetary Trip Scenario Surface Operations Scenario DMC Release through Touch–Down Scenario Rover Module commanded to execute at least 3 checkouts: During the SC commissioning Half way to Mars Before the DM separation from the CM Rover Module powered off Rover Module powered on starting from PLTE Surface Mission execution ExoMars ESWT#7 9 Dec 2014

Rover Command & Control Pre-Launch Phase: ROCC is responsible for the ExoMars Rover Module activities and will provide direct support to 2018 ESOC/MOC. ESOC/MOC route the data to/from ROCC Inputs and support from Science teams necessary to evaluate PPL Instruments behaviour LEOP: limited operations: execution of the Rover Module checkout as part of the Spacecraft Composite IOCR. ROCC is responsible for providing direct support to 2018 ESOC/MOC whenever deemed necessary. Inputs and support from Science teams necessary to support PPL checkout and to evaluate PPL Instruments behaviour Cruise Phase: The Rover Module will mainly be in OFF status with the exception of the periodic checkouts (at least 2), the On-Board SW uploading and the Rover Battery charging. ROCC is responsible for the ExoMars Rover Module activities and will provide direct support to 2018 ESOC/MOC No real time operations ExoMars ESWT#7 9 Dec 2014

Rover Command & Control DMC Phase: The Rover Module is OFF until the beginning of the PLTE Phase (after the touchdown) when the Rover is powered on, executes a checkout and leaves the landing platform Until Rover egress completion, 2018 ESOC/MOC is responsible for the joint (Rover + Surface Platform) operations After the handover between 2018 ESOC/MOC and ROCC, ROCC is responsible for commanding & controlling the Rover Module Inputs and support from Science teams necessary to evaluate PPL Instruments behaviour for the checkout Based on the current planning, the checkout of the PPL instruments is going to be split into two parts: the first executed soon after the Rover is powered-on and limited to the instruments supporting the egress preparation activities (e.g. PanCam) The second executed once the Rover is on the Martian soil Inputs and support from Science teams necessary to evaluate PPL Instruments behaviour are requested ExoMars ESWT#7 9 Dec 2014

Rover Command & Control Surface Phase: Rover Surface Operations Phase is a combination of the operations involving both the mobility of Rover and the analyses of selected Martian surface and sub-surface targets This mission phase is under control of ROCC. This mission phase will be performed during Mars daylight; night-time activities will be limited to support possible communications with the ESA TGO Data Relay Orbiter and, possibly, some data compression. The Rover engineering and scientific supporting teams will be organised on working shifts, which could be different because of their roles and responsibilities, suitable to always assure the full support to the surface activities. Indeed, along the evolution of the surface mission proper tailoring will be pursued to increase the efficiency in supporting the Mars tasks and to enhance the promptness of the Earth reply. The supporting teams are responsible for rover surface activity planning, for data assessment, trend analyses, recovery procedures definition etc. etc. The ground activities will require tight cooperation between engineering and science personnel to assure the accomplishment of all the mission goals. Scientific data will be transferred to Earth following proper rules (critical data first) through ESA TGO Data Relay Orbiter that will get the data sent by the Rover ExoMars ESWT#7 9 Dec 2014

Science decisions and trades As a high level summary, the main objective of the rover is to acquire a sample and analyse it (and do this several times !). Survey instruments are all contributing to decide where is the right location to drill. The Science activities on the ground must focus on the following questions: From the current place of the rover, where is the most suitable site at a reasonable distance? Trade various options and establish the longer term plan (this site and then this next etc…) to be revised as part of the continuous strategic planning activities. Detailed analysis of the selected landing site will provide the initial inputs, complemented with all other measurements. At the site, what are the local features that must be studied to allow selections of the drill site among possible candidates? Trade various candidates and number of measurements with the survey instruments. What is the best drilling location and depth ? What is the best ALD instruments measurement parameters and sequence to analyse the sample?

Engineering Support Support to the main scientific decisions and trades: Localisation of the rover Note that visual localisation is well progressing with Scisys under Airbus DS contract. VisLoc will implement the same algorithms that have been tested in the Atacama desert experiment SEEKER and SAFER. Mobility assessment to the various desired targets Drilling assessment of the various desired locations. Energy assessment of the desired plan More details in Sol#2 about the Tools provided by ROCC ExoMars Project <9 Dec 2014> < ESWT#7 >

Measurement Cycle Implementation Assumptions The development of the Measurement Cycle is mainly based on the two ESA normative documents: Reference Surface Mission and PPL E-IRD Every day, ROCC has to uplink the Activity Plans covering the following two sols of operations: in case of Decision Point, all the telemetry data necessary to prepare the Activity Plan shall be available at ROCC. In the other cases, the Activity Plan is prepared based on assessment of previously received telemetry data and the related data trend analysis Nine Decision Points are ruling the Measurement Cycle operational sequence Driving requirement: Drill is retracted at sunset to prevent freezing of the rod. Drill is re-positioned at next sunrise at the previous sol depth to start again the drilling activity RSM OPTIMISATION SCOPE ExoMars ESWT#7 9 Dec 2014

Measurement Cycle Implementation Assumptions Differences introduced by TASI wrt the ESA Reference Surface Mission document Drilling region characterization split over two sols because of the long duration of the operations RLS calibration not executed in sol 4 (the sol previous the one in which RLS is operated) because of timing constraints MOMA LD-MS operated in a dedicated sol because of thermal constraints (agreed after a joint discussion but not yet implemented in the ESA RSM) The drilling sequence has been implemented considering loose soil down to 140 cm (instead of 130 cm) to squeeze as much as possible the drilling sequence in a reasonable time Ma_Miss operations modified trying to make the duration of the activities compliant to the maximum allowed Rover working time (10 hours) RSM OPTIMISATION SCOPE ExoMars ESWT#7 9 Dec 2014

Vertical Survey Implementation Assumptions The development of the Vertical Survey is mainly based on the two ESA normative documents: Reference Surface Mission and PPL E-IRD Every day, ROCC has to uplink the Activity Plans covering the following two sols of operations: in case of Decision Point, all the telemetry data necessary to prepare the Activity Plan shall be available at ROCC. In the other cases, the Activity Plan is prepared based on assessment of previously received telemetry data and the related data trend analysis Ten Decision Points are ruling the Vertical Survey operational sequence Driving requirement: Drill is retracted at sunset to prevent freezing of the rod Drill is re-positioned at next sunrise at the previous sol depth to start again the drilling activity The ESA Reference Surface Mission document does not report the specific operations composing the Vertical Survey.
