Mauro Piermaria 3  NHXM is the ASI program with the aim to launch a new mission for Hard X-ray observations  Pre-phase A study, in the NHXM frame, mainly relevant to the Simbol-X collaboration has been conducted; 9/2006 – 1/2007.  NHXM phase A contract with Mirror technological development, MSC satellite of Simbol-X development and Exit-Sat Satellite development started in 7/2007.  First change with deeper analysis on mirror technology (Ni-Co electroforming, Multilayer deposition)  Second change with the development of a common platform for MSC and DSC (to be used also for EXIT-SAT)  Conclusion of the NHXM phase A (Simbol-X and Exit-Sat phase A), 1/2009. Initial duration of 13 months, extended to 18 months.  A further technological study (only on X-rays multilayer mirrors), continuation of the work performed during the NHXM phase A, has been initiated in 3/2009, and still on going. DEVELOPMENTS OF THE ASI NHXM PROGRAM

New Hard X-ray Mission Workshop; ASDC, Frascati12-13 novembre 2009Ing. Mauro Piermaria 4  Continuous collaboration with CNES on Simbol-X program, while only Italian involvement on EXIT-SAT mission.  Continuous improvement of the knowledge by confrontation with our program partners  Conclusion of the ASI-CNES collaboration on Simbol-X Program, 4/2009.  Internal Agency resources (8+1 persons).  INAF resources (from different locations and institute)  Industrial resources (TAS-I, MLT, BCV, TPZ, INAF-OAB)  Large but efficient integrated team working on NHXM for almost 2 years.  Once again, demonstrated ability for such a team, to deal and interact productively with other international partners.

Mauro Piermaria 12  During the last period, ASI made big efforts to pursue the NHXM Program (financial and HR).  We envisaged a broad involvement by the Italian community, either scientific and industrial.  The Simbol-X project, and the collaboration with the French partners, unfortunately stopped, brought a lot of experience on this kind of mission, for both scientific and engineering issues.  Feasibility of Exit-Sat and Simbol-X missions at the end of the projects phase A has been proved. By the way, some Items of Exit-Sat mission need to be further investigated.  ASI (and the collaboration network) has availability of know how, results and documentation on the above mentioned projects.
