INSIGHT Overview
 INSIGHT objectives
 Determine the inner contents of Mars (crust, mantle, core)
 Measure Mars seismic activity
 Measure Mars meteorite impacts
 Instruments are onboard a Lander
 CNES is in charge of the main
instrument, SEIS, a seismometer.

 Common functions
 acquire instrument data
 apply scientific algorithms on those data
 distribute the resulting product files to the involved scientific community
 manage data in a dedicated catalog
 monitor the instrument health
 Design, Develop, Test and Maintain
 Catalog for data management
 Data processing
 Custom applications
 Integration with CNES mission center frameworks

What we learn’t
 Low bandwidth for input data does not mean « easy to process »
 Very low data volume to process each day : ~ 10 MB / day …
 … but very high compression ratio
  ~ 10 millions of objects to process per day
• Time interpolation for data timestamping ;
• Complex scientific algorithms on each object
 Must be carrefully handled in Python data processing code
• Memory Management
• Single object structure and denormalization
 Best solution to reduce time processing is to not perform processing at all !!
• Find workaround to not apply a processsing on each objects

Wrap up
 FIMOC has been operational since 2012
 Maintenance ensured by Capgemini ;
 Constant evolutions  matured architecture
 No martian has been found yet !!
 … but a lot of knowledge acquired about Mars environment
 SISMOC
 Development is still in progress : integration of meteorit impact detection processings
 Very fascinating projects
