RFI for Concepts for the Next NASA X-ray Astronomy Mission – Corrections

Note: The RFI for Concepts for the Next NASA X-ray Astronomy Mission issued on September 13, 2011, is being corrected as follows:
— The incorrect label “Dear Colleague Letter” has been replaced by the correct label “Request for Information.”
— The page limit for responses is 10 pages. It was incorrectly stated as being 7 pages in one place in the full text of the RFI.


Concepts for the Next NASA X-ray Astronomy Mission
Solicitation number: NNH11ZDA018L

Release Date: September 13, 2011
Response Date: October 28, 2011

The National Aeronautics and Space Administration (NASA) and its Physics of the Cosmos (PCOS) Program is soliciting information through this Request for Information (RFI) pertaining to potential X-Ray astronomy missions. Specifically, NASA is seeking information that can be used to develop concepts that meet some or all of the scientific objectives of the International X ray Observatory (IXO). Information being sought includes relevant mission concepts, instrument concepts, enabling technologies, or any aspect of flight, ground or launch systems architecture.

The PCOS Program Office will work with the science community to develop new X-ray astronomy mission concepts satisfying some or all of the scientific objectives listed in Table 1. Such scenarios might include one or more observatories. These scenarios will be presented to the National Academy of Sciences Committee on Astronomy and Astrophysics (CAA) for consideration. Recommendations from the CAA will subsequently be used to guide detailed development of scientific, technical, and cost information for some or all of these X-Ray mission concepts. Data from these concept studies will also be used to assess future technology needs for the Astrophysics Division. Information from the technology assessment will also be provided to the CAA.

This Request for Information (RFI) is the first step in this process. Through this RFI, NASA is seeking information relevant to an X-ray astronomy mission concept or mission concepts that will satisfy some or all the scientific objectives listed in Table 1. The RFI also requests standalone instrument concepts as well as relevant key enabling technologies for such missions or instruments. Mission concepts should range in cost from ~ $300M to $2,000M in FY12 dollars.

The full text of the request for information is posted on the NASA research opportunity homepage at http://nspires.nasaprs.com/ (select “Solicitations” then “Open Solicitations” then “NNH11ZDA018L”).
