Presentation EddiCam consortium, FF, Madrid 13/06/2002 Eddington programmatic status Fully approved by SPC as part of ESA’s science program as project (“reserve status” dropped) in May Single project w/ Herschel and Planck: –Herschel platform reuse –Integrated project team Launch 2007/2008 –Flexibility in launch date depending on P/L availability –Extremely tight development schedule requires fast P/L procurement

Presentation EddiCam consortium, FF, Madrid 13/06/2002 P/L procurement approach Integrated approach to P/L (telescope + camera) Joint procurements, ESA + PI contribution Define PI-procured items now

Presentation EddiCam consortium, FF, Madrid 13/06/2002 Next steps Prepare Science Management Plan (SMP) SMP describes the implementation of the mission –Must define PI responsibilities, data rights, etc. –Pre-requisite for an AO Define PI-procured items now

Presentation EddiCam consortium, FF, Madrid 13/06/2002 Eddington P/L definition Eddington P/L current baseline (Astrium study) comprises 4 (identical) telescopes Each telescope includes Optical assembly (OA) Optical bench (OB) Focal plane assembly (FPA) Front-end electronics (FEE) Data processing unit (DPU) Complete P/L to be procured by ESA+PI+Industry team Industrial components will be procured through open ITT PI components to be procured through AO

Presentation EddiCam consortium, FF, Madrid 13/06/2002 Eddington definition: further steps ESA project team to be formed soon No detailed schedule, etc. available prior to establishment of formal project team. But: –SMP to be submitted to AWG on Oct. 1, 2002 –Definition phase (A+B1) to be completed by 1Q 2003 to allow start of phase C/D in 2004 –Option for (cheap) copy of Herschel bus expires in July 2003 Define PI contributions now

Presentation EddiCam consortium, FF, Madrid 13/06/2002 Eddington possible PI contributions PI contributions must be realistic –Financially (compatible w/ available national funds) –Technologically (compatible w/ available facilities, expertise in national labs) –Schedule-wise (must not risk impacting project schedule – specially important given special Eddington status) Today’s discussion beginning of this project AO (and SIP) will be written keeping into account today’s discussion
