Call for Payload Study Consortia for the International X-ray Observatory (IXO) - a Cosmic Vision L-class mission candidate

Call for Payload Study Consortia for the International X-ray Observatory (IXO) - a Cosmic Vision L-class mission candidate

28 April 2009

On 28 April ESA issued a "Call for Declarations of Interest in Science Instrumentation" for the L-class Cosmic Vision mission study IXO. Prospective Instrument Study Teams are invited to submit proposals outlining the composition of nationally funded consortia to carry out assessment level studies.

The deadline for submitting proposals has passed.

ESA is currently carrying out an assessment study phase for a number of L-class missions which are candidates for the first launch slot (possibly in 2020) in the Cosmic Vision plan. All currently studied L-class mission concepts will undergo a competitive selection at the end of 2010, from which 2 missions (out of the 3 currently under study - IXO, Lisa, and EJSM) will be selected for definition studies extending to the end of 2012. Eventually, only one mission will be adopted for flight with the industrial implementation phase starting in 2013.

The instruments for the Cosmic Vision L-class missions are foreseen to be funded by the national agencies and provided by consortia of institutes led by Instrument Study Leads. To enable the instruments to be defined at the same level as the other mission elements (platform, launch services, etc.), the assessment-level studies for the instrumentation will have to be nationally funded and will be carried out by the prospective Instrument Study Teams, in line with the general approach to science payload studies and development described in the Science Programme Committee document on "National Activities parallel to Cosmic Vision Studies", (ESA/SPC(2008)3).

Prospective Instrument Study Leads are invited to respond to this call with details of the composition of nationally funded consortia and of the proposed work-plan. These consortia are expected to carry out assessment-level studies of the scientific instruments for the IXO Cosmic Vision mission study. A description of the scope of the studies, the consortium structure and selection procedure, and interfaces with the ESA-managed system study is provided in this call, which can be downloaded from the right-hand menu.

A number of documents are included in this call:

- A call for declaration of interest in science instrumentation for IXO
- The draft Payload Definition Document (PDDv6) for IXO

The draft Science Requirements Document for IXO

- Document ESA/SPC(2008)3, "National Activities Parallel to The Cosmic Vision Studies"
