Call for White Papers for the definition of the L2 and L3 missions in the ESA Science Programme

5 March 2013

Update - 24 May 2013: The deadline for receipt of White Papers has passed.

Large (L-class) missions are the pillars of ESA's Science Programme, representing the stability and long-term planning for the scientific community and the ESA Member States. The definition of the Programme's pillars should rely on an adequate long-term perspective. This is needed to achieve the adequate technological and scientific preparation required by missions that set out to provide a significant, paradigm-changing advance in their respective fields.

The ESA Science Programme can implement three L-class missions every 20 years (two decades being the planning horizon covered by the Programme's successive long-term plans). Considering that the JUICE mission was recently selected for the L1 launch opportunity in 2022, the two other L-class missions (L2 and L3) can be launched in approximately 2028 and 2034.

Selection process for the L2 and L3 missions

The L2 and L3 missions will be defined through a two-step process: first selecting the science themes and questions that should be addressed by each of the two missions through this Call, and then selecting, in due time, the actual mission and payload consortia through dedicated Calls for Missions, issued at a later time.

The Director of Science and Robotic Exploration has appointed a Senior Survey Committee to advise him on the definition of the science themes. The SSC will attend an open workshop [link to workshop page] at which scientists who proposed new themes (in the form of White Papers) have been invited to present their ideas. After consultation with the Space Science Advisory Committee, the White Paper spokespersons, and additional members of the scientific community, theSSC will make a recommendation to the Director for the themes for the L2 and L3 missions. Based on this, the Director will make a proposal to the Science Programme Committee (SPC) who will select the themes at their meeting in mid-November 2013.

The Calls for Missions will be restricted to the science areas identified as an outcome of the Call for White Papers. The current planning foresees the issue of the Call for the L2 mission in the course of 2014, and the issue of the Call for the L3 mission likely around the end of the present decade.

Defining the science themes for L2 and L3

This Call, open to the broad scientific community, solicits White Papers advocating science themes and questions for the L2 and L3 flight opportunities. The White Papers should focus on two key points:

the science questions that are proposed to be addressed by an L-class flight opportunity

one (or more) strawman mission concept(s), or possible approaches to obtaining the necessary measurements, that could provide the answers to the science questions proposed.

White Papers can also explicitly advocate observatory-type missions and survey-type missions.

Each White Paper must identify a spokesperson, who must be available to present and advocate the White Paper's content.

The White Papers received will initially be subject to a screening to eliminate responses that are not of interest either technically or scientifically. Prior to submitting a White Paper authors are required to accept that the submitted material will be made public.

NOTE: Full details of this Call for White Papers are in the Call document, which is available from the right-hand menu.

Open Workshop

A number of spokespersons will be invited to present their case in an open workshop, planned to be held in Paris, on 3-4 September. The presentations will form part of the input to the selection process.

Timeline and deadlines

Proposals in response the present Call for White Papers are due by 12:00 CEST on 24 May 2013. Submission details are given below.
