                         unique tool for probing the dynamical properties of highly compact 
                         astrophysical objects, mapping ultrarelativistic regions of 
                         space-time, and testing Einstein's general theory of relativity. 
                         LISA (Laser Interferometer Space Antenna), a joint National 
                         Aeronautics and Space Administration and European Space Agency 
                         mission to be launched in the next decade, will perform these 
                         scientific tasks by detecting and studying low-frequency cosmic 
                         gravitational waves through their influence on the phases of six 
                         modulated laser beams exchanged between three remote spacecraft. 
                         By directly measuring the polarization components of the waves 
                         LISA will detect, we will be able to test Einstein's theory of 
                         relativity with good sensitivity. Since a gravitational wave 
                         signal predicted by the most general relativistic metric theory of 
                         gravity accounts for six polarization modes (the usual two 
                         Einstein's tensor polarizations as well as two vector and two 
                         scalar wave components), we have derived the LISA time-delay 
                         interferometric responses and estimated their sensitivities to 
                         vector- and scalar-type waves. We find that (i) at frequencies 
                         larger than roughly the inverse of the one-way light time 
                         (6×10\⊃-2Hz), LISA is more than ten times sensitive to 
                         scalar-longitudinal and vector signals than to tensor and 
                         scalar-transverse waves, and (ii) in the low part of its frequency 
                         band is equally sensitive to tensor and vector waves and somewhat 
                         less sensitive to scalar signals.",
