Space Interferometry Mission

Salient Features• 3 parallel Michelson Stellar Interferometers• 10 meter baseline• Visible wavelength• Launch Vehicle: Atlas V or Delta IV ELV• Earth-trailing solar orbit• 5 year mission life with 10 year goal• SIM is a JPL, Caltech, Lockheed Martin, KSC

• NGST, and SIM Science Team partnership

Science Goals• Perform a search for other planetary systems by surveying 2000 nearby stars for

astrometric signatures of planetary companions• Survey a sample of 200 nearby stars for orbiting planets down to terrestrial-type masses• Improve best current catalog of star positions by >100x and extend to fainter stars to

allow extension of stellar knowledge to include our entire galaxy• Study dynamics and evolution of stars and star clusters in our galaxy to understand how

our galaxy was formed and how it will evolve.• Calibrate luminosities of important stars and cosmological distance indicators to

improve our understanding of stellar processes and to measure precise distance in the distant universe

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

• 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.

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

• 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

Other:

• (N) Held (June 18) “Fireside Chat” on SIM Science with OSS AA- SIM contributions to astrophysics beyond planet finding

• (N) Gave a SIM status briefing to the Origins Subcommittee on July 1st- Covered project status and SIM contributions to astrophysics beyond planet

finding

- Concept for a large number (~20k) of medium accuracy (~50 uas) astrometry measurements in a guest observer like role was well received

• The 27th SIM Newsletter “Fringes” was published Jun 6th announcing and explaining the completion of NASA HQ milestone #5, MAM wide angle basic performance (needed for 30 uas wide angle astrometry)

• The 28th SIM Newsletter “Fringes” was published Jun 20th, announcing SIM’s completion of the major reviews required for Phase B entry (actual Phase B start was August 18th)

Near Term Plans

• AAS Atlanta, GA meeting Jan 4th through 8th- Special session on SIM GO program

• SIM cost to complete update planned for Jan through March- Delayed to Feb through April due to waiting for expected budget

changes in the President’s budget to be released in late January

• SIMTAC #32 meeting Jan 14th & 15th to set evaluation criteria for meeting HQ milestone #8 (due Feb 2004)

• SIMTAC #33 meeting (TBD, March?) to review results of HQ technology milestone #7, MAM wide angle goal performance that is due in Feb 2003

Manager’s Assessment

• SIM continues to make good progress towards technology completion- All four milestones needed for Phase B entry are now complete

- First two of four Phase C/D milestones completed (MAM Wide Angle Baseline Performance & MAM Narrow Angle Goal Performance)

• SIM completed transition to Phase B on schedule

• SIM System Requirements Review (SRR) completed in Nov, 2003 on schedule

• SIM is holding schedule so far, although budget changes from above may impact that soon
