Accomplishments Since ST#9 (1) Programmatic: • Launch vehicle changed from STS to Atlas V

Accomplishments Since ST#9 (1) Programmatic: • Launch vehicle changed from STS to Atlas V or Delta IV Expendable Launch Vehicle (ELV) June 22 nd Space Interferometry Mission - Held technical interchange meeting with KSC mission integration team on Oct 1 st & 2 nd • SIM completed transition to Phase B on August 18 th • System Requirements Review (SRR) completed Nov 18 -20 th SIM - 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 10 th - 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 A NASA Origins Mission SIM ST#10 Dec 16 -18, 2003 J Marr SIM Pgm Status, 5

Accomplishments Since ST#9 (2) • Updated SIM PLRA to Preliminary for SRR Space Interferometry

Accomplishments Since ST#9 (2) • Updated SIM PLRA to Preliminary for SRR Space Interferometry Mission - 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 $8 M budget reduction in FY 04 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 SIM • Awarded one Grid Star RV survey contract for the northern hemisphere A NASA Origins Mission SIM ST#10 - Verne Smith at U of Texas using Mc. Donald 2. 1 m 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. 5 m telescope with Cf. A/SAO portable spectrograph AFOE • Southern Hemisphere: Swiss 1. 2 m telescope in Chile using planet-finding instruments already in place.
