Mission to Mars !

Capgemini involvement in Mars exploration



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



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



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



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.



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

Application



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)



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
