Announcement of Opportunity for Euclid Payload and Science Ground Segment components

Announcement of Opportunity for Euclid Payload and Science Ground Segment components

22 July 2010

The Euclid Announcement of Opportunity (AO) solicits proposals from a single consortium to cover all nationally-funded contributions to the mission, namely: a) Elements of the payload, comprised of the two scientific instruments (VIS and NISP); b) Elements of the Science Ground Segment (SGS); and c) Consortium-appointed membership in the Euclid Science Team (EST). The deadline for submission of proposals is 29 October 2010, 12:00 CET.

The AO is open to individuals and scientific groups affiliated with institutions in ESA Member States. The schedule for the complete AO cycle and the Euclid programme is given below. Full details on the submission and proposal evaluation criteria are given in the Euclid AO document, which is included in the proposal information package (see documentation section below).

Euclid is an ESA mission with contributions from the ESA Member States and with a potential international participation. Euclid is currently in a competitive Definition Phase, together with PLATO and Solar Orbiter, as an M-class mission candidate for the 2017/2018 M1/M2 launch opportunities of the Cosmic Vision 2015-2025 Plan. At most two out of the current three candidates will be adopted for implementation in 2011. The responses to the current AO must be binding for the Definition Phase and in draft form for the Implementation Phase. Should Euclid not be adopted in 2011 for a launch in 2017 or 2018, all activities undertaken during the Definition Phase as a result of the present AO will cease.

It is the intention to select the Consortium for the Euclid mission on the basis of the present AO. Therefore, the proposal shall include all Consortium elements necessary for the Implementation Phase, clearly defining the task and level of commitment.

The schedule for the Euclid AO and approval cycle is:

July 22, 2010 Release of AO for Euclid

The proposal information package for this Euclid AO is available as a zip file and can be downloaded from the right-hand menu under "Documentation". This package includes the following documents:

  1. Cover Letter
  2. AO for Euclid Payload and Science Ground Segment
  3. Euclid Science Management Plan (SMP)
  4. Euclid Science Requirements Document (Sci-RD)
  5. Experiment Interface Document Part A (EID-A) draft
  6. Experiment Interface Document Part B (EID-B) template
  7. Proposal Templates
  8. Science Ground Segment Interfaces Document

Proposal content

The response to the present AO shall be split into four sections (or sub-proposals). The first section will cover the activities proposed to be carried out in the Definition Phase. The second section will be a draft proposal for the Implementation Phase. The third section will be the proposed Euclid Mission Consortium membership in the EST. The fourth section will consist of the Letters of Endorsement by the funding agencies.
For each of these four sub-proposals the cover page shall include:

  • The title of the proposal,
  • The names, addresses, telephone and fax numbers, and e-mail addresses of the proposal contact person,
  • The list of the supporting national funding agencies.

Full details of the guidelines for the content of the four sub-proposals are in the Euclid AO document, which is included in the proposal information package (as file #2).

Proposal Submission

Proposals shall be submitted electronically in PDF format using the proposal submission form that is accessible through the link below, or in the right-hand menu (the form opens in a new window).

Submission is closed

The proposals must be received not later than: 29 October 2010 at 12:00 Central European Time (CET).

The four sub-proposals (Proposal for Definition Phase, Draft Proposal for Implementation Phase, Proposal for Euclid Science Team Members and collated Letters of Endorsement) shall be submitted as a single tar or zip archive containing each sub-proposal as a PDF document. Each sub-proposal shall be limited in size to 50 Mb.

Note: The two sub-proposals 'Draft Proposal for Implementation Phase' and 'collated Letters of Endorsement' shall be packed together into one tar or zip archive, meaning there are 3 instead of 4 tar/zip archives to make up a complete submission. See also the notes on the submission form.  

In parallel, a hardcopy signed version shall be submitted by the same deadline to the following address:

Ana M. Heras
P.O. Box 299
2200 AG Noordwijk
The Netherlands

The proposal contact person shall inform the address above by e-mail of the mailing date of the hardcopy version of the proposal and of the electronic submission. ESA will confirm by e-mail the reception of the proposal hardcopy and electronic version.

In addition, a copy of the complete proposal must be sent to each of the funding agencies that have provided a Letter of Endorsement.

Letter of Intent and briefing meeting

Proposing parties are requested to send a Letter of Intent by e-mail to the above address by 29 July 2010. It should contain the proposal title and the proposal contact person's name and contact details.

Possible questions in relation with the response to the AO may be attached. After reception of the Letter of Intent, ESA will invite the proposing parties to a briefing and clarification meeting that will be held on 27 August 2010 (TBC) at ESTEC. Submission of the Letter of Intent and attendance to the briefing meeting are compulsory.
