A update on PLATO status in the Cosmic Vision contest

Catania, 28 Feb 2011 PLATO TOUs 4

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 5

Evaluation report about PayloadPayload

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 7

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 8

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 9

Goal of the present meeting

Review the status of the TOU project: optical design, straylight analysis, mechanical design of structure and

baffles, thermal analysis, optical materials and coating, prototyping activities, implementation development plan.
