Phase E

Operations

Converting the preliminary plan into a baseline technical solution- define requirements (SRR)- determine schedule- specifications to initiate system design and development (SSR)

Design&Production- create subsystems- Invitation To Tender (ITT)- design equipments- select materials, processes- procurement- manufacturing- tests- integration

Mission- launch- cruise- experiments/services- data acquisition- data analysis
