National Aeronautics and Space Administration Jet Propulsion Laboratory California Institute of Technology SIM Lite A STROMETRIC O BSERVATORY CALTECH SIM-Lite Instrument Description, Operation and Performance SIM Lite would search about 60-100 nearby Sun-like stars for planets of mass down to one Earth mass, in the Habitable Zone. SIM-Lite will also perform global astrometry on a variety of astrophysics objects, reaching 4 μas absolute position and parallax measurement accuracy on objects brighter than 16th visual magnitude and 10 μas at magnitude 20. The instrument consists of: – A 6m Optical Michelson stellar interferometer – A 4.2m “Guide” Michelson stellar interferometer – A 30cm “Guide” Telescope. The first interferometer chops between the target star and a set of reference stars. The second interferometer monitors the attitude of the instrument in the direction of the target star. The telescope monitors the attitude of the instrument in the other two directions. 9/10/200910Renaud Goullioud Science Guide 4.2-meter Baseline Guide 1 Guide 2 Science Bay 1 Astrometric Beam Combiners Bay 2 Guide 1 Science 6-meter Baseline T R1R1 R2R2 R3R3 R4R4
