J Marr SIM ST#10 Space Interferometry Mission A NASA Origins Mission SIM Dec 16-18, 2003SIM Pgm Status, 5 Accomplishments Since ST#9 (1) Programmatic: Launch vehicle changed from STS to Atlas V or Delta IV Expendable Launch Vehicle (ELV) June 22nd -Held technical interchange meeting with KSC mission integration team on Oct 1st & 2nd SIM completed transition to Phase B on August 18th System Requirements Review (SRR) completed Nov 18-20th -Level 2 Preliminary; Level 3 Draft; Level 4 Key/Driving -Navigator Program Independent Review Team (NP IRT) briefed NASA OSS Astronomy & Physics Division (APD) on Dec 10th -No significant issues Decision made to move responsibility for Lockheed Martin (LM) effort from LM to JPL following significant phase B cost estimate increase -Collector subsystem; Metrology subsystem; Instrument Integration & Test -Transition underway now

J Marr SIM ST#10 Space Interferometry Mission A NASA Origins Mission SIM Dec 16-18, 2003SIM Pgm Status, 6 Accomplishments Since ST#9 (2) Updated SIM PLRA to Preliminary for SRR -Format has changed somewhat (still evolving) to make actual Level 1 requirements clearer -See PLRA for details (in ST folder on sim-lib, ‘Collection 817’) SIM was given an $8M budget reduction in FY04 by the House Appropriations Committee (HAC) to cover a small piece of the NASA “earmarks” -Estimated impact is 1 to 1.5 month slip in SIM schedule but details of what work will slip have not yet been completed Awarded one Grid Star RV survey contract for the northern hemisphere -Verne Smith at U of Texas using McDonald 2.1m telescope with echelle spectrograph with iodine cell -Developed a plan for non-competitive contracts to provide remaining sky coverage Equatorial Band: Mt. Wilson Observatory 2.5m telescope with CfA/SAO portable spectrograph AFOE Southern Hemisphere: Swiss 1.2m telescope in Chile using planet-finding instruments already in place. Also have backup options.

J Marr SIM ST#10 Space Interferometry Mission A NASA Origins Mission SIM Dec 16-18, 2003SIM Pgm Status, 7 Accomplishments Since ST#9 (3) Technical: Held SIMTAC #30 at JPL (Jun 26th & 27th) -Topics: LV trade; Astrometric Error Budget; Modeling updates in several areas; Tighter AACS trade study; SIM alignment; Instrument electronics design; MAM milestone #5 update Held SIMTAC #31 at JPL (Sep 9th & 10th) -Topics: AEB peer review; Grid star plan; Removal of field dependent astigmatism; MAM latest results; TOM 1c status; Spacecraft slew and settle; and Dynamics & control requirements & verification Met HQ Milestone #6, Narrow Angle Goal Performance -SIMTAC and NP-IRT concurred with achievement of 20 pm against goal performance of 24 pm needed for 1 uas narrow angle astrometry Requirements and design reviews held for Brassboards needed for technology milestone #8

J Marr SIM ST#10 Space Interferometry Mission A NASA Origins Mission SIM Dec 16-18, 2003SIM Pgm Status, 8 Milestone#6: MAM Narrow Angle Results 0+0.5degree-0.5degreeField position TR4TR2TR3T SSSSSS 30 s TR5R2 S….SS time T R2R2 R4R4 R5R5 R3R3 Results Benchmark capability of the MAM single baseline interferometer, used as the SIM science interferometer sensor would be used in the narrow angle (1 deg field of regard) planet finding deep- search mode, to perform at the ‘goal’ level (24 pm) needed for 1 uas astrometry. The project will continue investigating reasons for the data dispersion (resulting in the large standard deviation) as part of continuing Milestone #7 activities Overall SIM Narrow Angle Astrometry performance predict is currently 1.2 uas vs 1.0 uas goal
