The project lifetime is 10 years and has the following consecutive phases: Phase 1 (years 1 to 3): The engineering design and development requires 3 years. No production is done during this period Phase 2 (years 4 to 10): to launch the spacecraft into orbit, operate the equipment from the ground by remote control, and recover the spacecraft with the product.
