SOFIA SOFIA Science Steering Committee Meeting Palmdale, Feb 18, 2010 Dietmar Lilienthal / Alois Himmes

DLRSSSC Palmdale, Feb 18, Programatic aspects in Germany New government in Germany since autumn 2009 keeps Science and Technology a high priority DLR budget for 2010 unchanged, expectation is continuity for the coming years SOFIA budget stable for the medium term period , implemented in DLR long term planning beyond 2012 Rev of JSPP II signed by NASA and DLR

DLRSSSC Palmdale, Feb 18, Science Mission Operations Deputy director The international search committee for the (DSI funded) SMO Deputy Director recommended a candidate to DLR, unanimously DLR authorized DSI / Universität Stuttgart to start negotiations with the selected candidate Decision expected soon

DLRSSSC Palmdale, Feb 18, Major technical achievements since autumn 2009 Identification of Gyro failure and repair at IXSEA (in France) and provision of 4th (spare) gyro. Successful re-integration and tests during several LineOps Additional Line Replacable Gyro Box / Gyros to be procured at IXSEA, delivery early 2010 Continued repairs and improvements of the Telescope Assembly (TA) and procurement of most needed spare parts Another TA LineOps demonstrated TA readiness to start next phase of closed and open door flights with passive and activated TA TA-activation but still closed door flight in Jan 2010 including simulated observing legs showed promising results. Details in separate presentation by Thomas Keilig at SITR

DLRSSSC Palmdale, Feb 18, Issues and Concerns as seen by DLR (1) The MPE in Garching announced to terminate their involvement in SOFIA DSI with support from USRA/SMO and DLR is investigating how FIFI-LS can be finished, maintained and scientifically used as Facility Instrument, see separate presentations by Thomas Wegmann and Randolph Klein DLR continues to support both German science teams to bridge the gap until science results are demonstrated. The continous schedule delays required an extension of those grants by 2 years to Dec This is still valid also for FIFI-LS, depending on a successful FIFI-LS recovery plan Both grants are funded from the same budget line as the DSI, thus reducing the money available for Telescope related activities

DLRSSSC Palmdale, Feb 18, Issues and Concerns as seen by DLR (2) The funding of the Science Teams by MPG had already been substantially reduced or even stopped (DFG) since The MPE is one of the leading institutes for IR-Astronomy in Europe. Termination of the MPE-involvement in SOFIA, which will have been definitely noticed by German funding authorities, makes the situation even worse Yesterday, ESAs Science Programme Committee decided to continue with the definition phase for the ESA part of the Japanese IR-Mission SPICA. ESA would provide the 3,5m cryogenic telescope, and European member states one major instrument SAFARI (imaging Fourier Transform Spectrometer). Putting all these indications together, the perspective for the development of next generation SOFIA instruments and thus the continuation of a German participation in SOFIA has not improved over the last years, month and weeks in Germany
