Abstract A concept of testing the equivalence principle with optical readout in space (TEPO) has been proposed [J. Jpn. Soc. Microgravity Appl. 25 (2008) 423]. We further discuss the feasibility of TEPO using LISA (laser interferometer space antenna) Pathfinder technologies, such as a heterodyne interferometer, an inertial sensor, drag-free control and discharge technique, and determine that the equivalence principle could be tested at 8×10−17 with one day integration.
