Phase B1: SRR Objectives 1/2 Premises PLATO Phase B1 objective is the adoption of the PLATO mission by SPC in Feb-March 2016. The PLATO System Requirements Review (SRR) to be completed by January 2016 is a major input to PLATO mission adoption. The SRR is a formal review (category 1 i.e organized by ESA inspector general, D/SRE is the chairman). The primary objective of the SRR is to review in detail: The final payload and spacecraft system specifications, The payload and spacecraft design definition, The payload and spacecraft development and verification program, Mission programmatic and cost. Catania, 11 June 2014 TOU Meeting

Phase B1: SRR Objectives 2/2 Premises The camera development schedule is critical, and is actually defining the schedule critical path for the spacecraft. Hence: The camera detailed design activities (including AIV plans and Ground System Equipment design) shall be completed before the SRR, The critical bread-boarding activities (e.g. electronics Demonstration Models, optics) shall be initiated during phase B1, Consortium input to the SRR shall demonstrate that the camera Engineering Model - which is fully representative of the flight model except for some electronics parts - will be completed by early 2017, A detailed development plan of the payload shall demonstrate by SRR that: serial production phase will start by mid-2017, the first batch of 8 cameras will be delivered in November 2020, the last batch of cameras will be delivered by November 2021. ?? Catania, 11 June 2014 TOU Meeting

TOUs during PLATO 2.0 Phase B1 goal Our proposal: deliver all ready but undelivered documents: Design: Consolidated TOU Design Report (Optical Design, Mechanical Design, Thermal Analysis, Stray-light Analysis, Optical Material Analysis and Coating Design, ..) Breadboard: Consolidated BreadBoard AIV report NEW: including a critical review of results and assessment of some open issues CaF2 tests AIV Design: Consolidated TOU MAIT and Management Plan Consolidated AlBeMet® Mechanical Structure Procurement Assessment Study NEW: F-TOU Filters Design Procurement Assessment Study

TOUs during PLATO 2.0 Phase B2 goal Design: Engineering of TOU Design (Optical Design, Mechanical Design, Thermal Analysis, Stray-light Analysis, Optical Material Analysis and Coating Design, ..) Breadboard  Prototype Lens set like the FM one (change of 2 lenses and replacement of one lens previously accepted with no conformance issue because short in time optical quality test (in term of PSF shape and dimension) on the whole FoV. AIV Design: Finalized TOU MAIT and Management Plan Finalized AlBeMet® Mechanical Structure Procurement Study Consolidated: F-TOU Filters Design Procurement Assessment Study Catania, 11 June 2014 TOU Meeting

When Industrial Prime Contractor? Our proposal: During Phase B1, industry will deliver consult and services. We’ll work to have ASI delivers a ITT for Phase B2/C contract, not later than March 2015. Goal: TOU Prime Contractor at work at beginning of Phase B2, but clearly identified before the SRR. Catania, 11 June 2014 TOU Meeting
