  3. 3. Mars Exploration Projects | 2016-09-26 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 3 Capgemini is involved in Mars exploration missions  Two Mars exploration missions  Mars Science Laboratory (MSL) : operational since 2012  Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (INSIGHT) : currently in development, launch foreseen on March 2018
  4. 4. Mars Exploration Projects | 2016-09-26 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 4 Mars Science Laboratory overview  MSL objectives  Investigating Mars’s habitability  Studying its climate and geology  Collecting data for a manned mission to Mars  International cooperation :  Nasa, JPL, Space Agencies and Laboratories  10 distinct instruments onboard the Curiosity Rover
  5. 5. Mars Exploration Projects | 2016-09-26 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 5 CNES contribution to MSL  In charge of the development of two instruments  CHEMCAM : nature and composition of rocks  SAM : organics and gases from both atmospheric and solid samples CHEMCAM SAM
  6. 6. Mars Exploration Projects | 2016-09-26 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 6 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.
  7. 7. Mars Exploration Projects | 2016-09-26 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 7 Capgemini contribution to MSL and INSIGHT  Realization of Operation Centers of CNES instruments  FIMOC : the MSL Operation Center  SISMOC : the INSIGHT Operation Center  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

All rights reserved. 9 Main Technologies based on proven open sources  Languages and frameworks  Java 7/8 : application frameworks and Data Portal • Spring • Tomcat  Python 2.7 : Mission specific data processings • Scientific libraries : Numpy, Scipy, Obspy  Angular JS : Web Portal  Databases  PostgreSQL : SAG data catalog  MongoDB : WEB Portal  Data processing  Torque : Cluster resource management and job submission  Technical Monitoring  ELK (Elasticsearch, Logstash, Kibana)
  10. 10. Mars Exploration Projects | 2016-09-26 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 10 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
  11. 11. Mars Exploration Projects | 2016-09-26 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 11 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
