  4. IMPLEMENTATION STATUS • Spacecraft design is sound • Effective management in place • Highly talented and motivated team • Well on the road for October CDR

  5. IMPLEMENTATION • Rapid Spacecraft Development Office • Unique “catalog-based” IDIQ contract • 8 Vendors; 18 Spacecraft • Selection is “rapid”; award-to-launch ~ non-RSDO • Fixed-price performance-based Delivery Order milestones • D. O. Management • Admin: CDRLs, studies, milestones • Technical: analyses, margins, requirements compliance • Deliverables: • Spacecraft/Observatory • Simulators (Interface, Observatory, Software Development) • Launch Support • Mission Operations Support
