ESA UNCLASSIFIED – For Official Use Points of discussion for RSM template TAS-I will address the RSM optimisation based on ROSEX Sol#2. Since the last ESWT, work has been done to propose solutions to the following points:  Ways to fit WISDOM grid in one sol:  WISDOM has proposed ways to reduce the grid (length, number of point turns, accumulations)  Other ways are being evaluated by TAS-I (e.g. driving faster, using NavCam instead of PanCam, etc…)  Raman calibration  The RLS Team has proposed a calibration sequence with a shorter duration.  We need check using ROSEX if it can be reintroduced the day before RLS runs.  Number of measurements, compression ratio and data volume vs. bandwidth (150 Mbits/sol constraint);  TGO has a new orbit, the so-called frozen orbit 370:30. It allows a finer scan of the planet. The new orbit presents no major impacts for data relay capabilities.  TAS-I is consolidating the data relay estimates —to be considered for the Rover/SP sharing discussions.  To fit the various resource constraints we will require some flexibility in the measurements each instrument needs. To be iterated as the resources evolve e.g. Ma_Miss measurements vs. drilling.  PanCam-HRC commanding  No more on-board algorithms for choosing HRC/ISEM targets from WAC images.  Instead, targets for HRC/ISEM will be identified on ground (e.g. based on previous PanCam and HiRISE images). On-board computation will determine the correct “point and tilt” values —taking into account the actual position of the rover after the last drive— to ensure the targets can be imaged. There will be NO EXTRA SOL introduced to decide where to point HRC/ISEM.  Coordinated science in ALD:  Difficulties with SPDS eccentricity and thermal gradients for fine positioning.  Difficulties with relative positioning and target knowledge for RLS. 5

ESA UNCLASSIFIED – For Official Use Data Relay Sharing Strategy 7  ON-GOING  Tests with ELECTRA to confirm the time necessary to reconfigure between the two assets communication for the same pass (essential for pass sharing)  TAS-I is consolidating the data volume requirement based on ROSEX runs performed with each instruments’ inputs (resource consumption)  TAS-I & ALTEC are formulating the TGO data relay needs on the basis of two communication passes per sol for the rover.  LAV/IKI/ESA are working on the consolidation of the Surface Platform payload suite and associated operations needs. Probable AO early next year.  STILL TOO EARLY TO FREEZE A DATA SHARING STRATEGY.
