A update on PLATO status in the Cosmic Vision contest Catania, 28 Feb 2011 PLATO TOUs

Where we are Start of Definition Phase with two parallel industrial contracts: Jul 2010 Jul 2010 ESA Call for PLATO Mission Consortium Oct 29, 2010 PMC Proposals Due Nov 2010 – Feb, 2011 Proposal evaluation: ESA panels  AWG SSAC SPC decision (10-11 Feb 2011) Proposal Evaluation Committee Report The Evaluation Committee recommends the pre-selection for the Definition phase of the PLATO Mission Consortium constituted as described in the proposal. The Evaluation Committee recommends that the pre-selected PLATO Mission Consortium proceeds with the activities leading to the elaboration and update of the proposal for the Implementation phase, following closely the guidelines given in this report. The Evaluation Committee requests an intermediate review in the March 2011 timeframe to assess the status of the major findings and of the implementation of the recommendations in preparation of the Implementation phase proposal. Catania, 28 Feb 2011 PLATO TOUs

Evaluation report about Payload The Consortium tasks for Payload are well defined but the level of definition for the implementation phase, specifically w.r.t. to the industrialization of the hardware production is low; i.e., potential industrial contractors are not identified and even a survey of potential suppliers is not presented. This omission is very serious considering the kind of recurring production for the PLATO payload where a strong industrial organisation will be necessary and raises a major concern on the realism of the schedule of the implementation phase. Recommendations: Complete with priority the industrialisation plan, finalise the definition of the planned interactions between the PLATO Mission Consortium and industry and define as early as possible the industrial resources needed for the “chain productions” of i.e., lenses, telescopes AIV, parts and material procurements. Consider cooperation with industrial partners as early as possible during the Definition phase to ensure a solid industrial basis for the Implementation phase proposal.

Future milestones Mar 2011 Intermediate review May 2011 Formal release of updated AO documents for implementation phase Jun 2011 Completion of industrial studies (Phase A) Jul 2011 Final proposal for implementation phase Oct 2011 M1/M2 mission selection Dec 2011 Completion of industrial studies (Phase B1) Feb 2012 Final adoption for the Implementation Phase (B2/C/D/E1) Jul 2012 Start of the Implementation Phase Launch: 2018 Catania, 28 Feb 2011 PLATO TOUs

Definition Phase Plan Validate technical critical points Confirm no need for new development Demonstrate TRL > 5 at the end of the definition phase Confirm no critical aspects in the procurement and AIV schedule of the implementation phase Allow fast transition to implementation phase Catania, 28 Feb 2011 PLATO TOUs

TOUs Specific Activities Study of spherical and aspherical lenses manufacturability and industrial plan Coatings (thermal, filter, AR): performance and low temperature Verification of lens alignment at ambient temperature Assessment of performances in operational temperature environment Link between performances in operational and ambient environment Thermal refocusing efficiency Validation of TOU AIV procedures at industrial level Catania, 28 Feb 2011 PLATO TOUs
