L-class candidate missions 


A special event was held in Paris on 3 February 2011, to present the three L-class mission concepts, EJSM-Laplace, IXO and LISA. These are the three candidates for a launch opportunity in 2020 within the frame of the Cosmic Vision 2015-2025 Plan for the ESA Science Programme.

Materials from the meeting, and reports from the assessment studies of the three L-class mission concepts, are posted on these pages. The following material has been uploaded and is available from the links below and from the right-hand menu:

Audio recording and presentations

An audio recording of the meeting is available for download. It is split into three parts corresponding to the three meeting sessions as indicated below.

In addition to the three mission presentations, the audio recording also includes the welcome address at the start of the meeting and the presentations on ESA programmatics and international partnerships at the end of the meeting.

The three audio files are in MP3 format and can be downloaded from the first column in the overview below. The file size is also indicated, along with the duration of the recording in hh:mm:ss.

For each of the three L-class mission candidates, EJSM-Laplace, IXO and LISA, the science case and an overview of a possible mission profile were presented, which was followed by a round of questions and answers.

The presentations are available as PDF and can be downloaded from the rightmost column in the overview below. For EJSM-Laplace and IXO the presentations of each mission are available as a single PDF. For LISA the two presentations are available as separate PDF documents.

Yellow Books and technical review reports of L-class study missions

Yellow Books

The outcome of the assessment study phase for each of the three candidate L-class missions is published as an assessment study report (Yellow Book). Each report provides a comprehensive overview of the scientific objectives and resulting requirements of each mission, along with details of the proposed payload, mission design and operations.

The Yellow Books are available for download in PDF format from the following table:

Yellow Books
EJSM-Laplace PDF 8.8 Mb
IXO PDF 6.5 Mb
LISA PDF 12.3 Mb

Technical review reports

For each of the three candidate L-class missions an ESA internal review has been completed at the end of the assessment study phase (phase 0/A). The reviews focused on the technical and programmatic elements of the three missions. The results of each review are summarised in a technical review report.

The three reports are available for download in PDF format from the following table:

The three L-class missions

Three "Large" (L-class) mission concepts, originally proposed to ESA in response to the Call for Missions for the Cosmic Vision 2015-2025 plan issued in 2007, are currently studied as candidates for a launch opportunity in 2020. Details of the three mission concepts (EJSM-Laplace, IXO and LISA) are available at

All three mission concepts are nearing the completion of their Assessment Phase study activities, and the Advisory Structure to the ESA Science Programme will be asked, in May of 2011, to recommend which of the three should be carried forward for Definition Phase activities. The Science Programme Committee will then decide on the matter in June of 2011.

As a first step in this process, the three L-class mission concepts EJSM-Laplace, IXO and LISA will be presented to the scientific community on 3 February 2011, at the Institut Océanographique de Paris (195 rue Saint-Jacques, 75005 Paris, France). The meeting is foreseen to start at 10:00 and will end at 19:30 with a reception planned for 18:30.

Update (6 Jan 2011): The meeting will start at 11:00 instead of 10:00.
The updated programme is linked from the right-hand menu.

All interested parties (scientific community, industry, national funding agencies, international partners) are invited to attend this event. Practical details and logistic information are available at the links in the right-hand menu.
