A project named EarthCARE/CPR is now going to be organized in Japan Aerospace Exploration Agency (JAXA) and National Institute of Information and Communication Technologies. Earth Cloud, Aerosol and Radiation Explorer; EarthCARE is a joint mission between JAXA and European Space Agency (ESA). And it is the sixth Earth Explorer project in ESA. Cloud Profiling Radar (CPR) will be developed by JAXA and NICT jointly and integrated with EarthCARE spacecraft, which will be developed by ESA. EarthCARE satellite will be launched in 2013. In Phase-A extension period of EarthCARE/CPR project, we analyzed risk of the project and made a plan to mitigate risks. Firstly, we categorized all risks into two types, i.e., project type and technical type. Project type includes project structure and schedules. On the other hand, technical one includes Technical Readiness Level (TRL) and development methodology. Secondly, we looked into each type risk and set counter actions for each risk. For project type risks, we recognized main risk is located in the cooperative structure between JAXA and NICT. In the project, NICT plays a equivalent role as JAXA for developing Flight Model subsystem and components. So we newly set a S&MA structure between NICT and JAXA, and use of common S&MA specifications, derived from JAXA standards. For technical type risks, we identified and reviewed all technologies used in CPR, and categorized in TRL matrix. Then JAXA made a development plan; front loading plan for new technologies to have sufficient TRL before Preliminary Design Review. The first risk management results are reviewed and admitted in the System Requirement Review of JAXA/NICT. The continuous effort to refresh this result is to be maintained through out the project period.
