Significant Progress! Open Door Flights have been highly successful –100% Open Door Flight completed; December 18, 2009 The Upper Rigid Door (URD) was opened incrementally to 100% of the Aperture opening, exposing the Cavity to the atmosphere for initial internal airflow and acoustics characterization tests Initial observations of the characteristics of the aircraft with the URD open up to 100% were benign, with no acoustics or aircraft handling issues Two Door Closed flights completed; January 14-15, 2010 –TA Activation flights successfully completed –Aircraft Functional Check Flight (FCF), clean-up flight Envelope Expansion flight series started with the 23 o (lowest) Aperture position on January 29, 2010 and completed Feb 11 –10%, 40%, 70% and 100% Door Open flight envelope expansion at low altitudes / low speeds nearly completed (Watch Flight Test Video) Landing with door open at 40% completed! 2

Challenges Actual Schedules have taken longer than planned –Analyzing actual data to adjust plans Recent schedule performance has taken about 1.4 times longer than 70% JCL –Flight test objectives have been successful, but taking longer than anticipated Weather Additional flights Cavity Door Drive (CDDS) anomaly Dryden evaluating ideas to shorten path to ISF –Addition of staff needed to shorten Mission Systems installations and checkout –More co-location at the DAOF along with key test assets –Parallelizing appropriate serial tasks –Scrubbing flight test matrix / approach Program working mitigation approaches for longer-term schedule –Established a separate Segment 3 planning and schedule development team –Evaluating several shorter downtimes vs. 1 extended downtime in Segment 3 4

Program Status (1of 2) Program prioritizing the remaining FY10 reserves to accommodate Platform surge, additional workforce and contract costs FORCAST Science Instrument is at DAOF –Initial integration and line ops in early-Spring FIFI-LS funding discontinued by Max Planck Institute –DLR/DSI investigating options to provide continuity in funding Continuing Phase 1 of EVM implementation / reporting; anticipate having full EVM reporting capability by May Monthly report Program will re-run Joint Confidence Level (JCL) analysis to support re-baseline activity with Science Mission Directorate and Agency Reviewing SOFIA Science Project Council report received on December 28, 2009 –Concern for potential schedule slip to ISF –Minimize extended aircraft downtime –Re-evaluate remaining instrument suite 8

Program Status (2 of 2) Operations Simulations –Operations Sim 7 slated for Feb at DAOF Sim 7 is basically a detailed planning session for Sim 8 Sim 8 will be a subset of FORCAST Line Ops #1 Data Cycle System –v1.2 – SS archival software and Basic Science call for Proposals Testing complete Report in review FCA/PCA on v1.2.1 (resolution of any outstanding problem reports) on Feb 26 SOFIA Science/New Instrument Workshop –Scheduled June 6-8, 2010, Asilomar Conference Center, Pacific Grove, CA –11 invited speakers (confirmed) who are theorists and/or observational astronomers. Instrumentation presentations to be given by poster only to provide for a level playing field during the proposal evaluations. –Electronic registration form has gone live as of today. Pipeline status: –Coordinating site visits to some of the major NASA observatory science centers to discuss “best practices and lessons learned” with the associated pipeline managers. –These discussions should aid in developing the SOFIA pipeline process. 02/04/2010 9
