We report the timing and spatial resolution from the Muon Telescope Detec- tor (MTD) installed in the STAR experiment at RHIC. Cosmic ray muons traversing the STAR detector have an average transverse momentum of 6 GeV/c. Due to their very small multiple scattering, these cosmic muons pro- vide an ideal tool to calibrate the detectors and measure their timing and spatial resolution. The values obtained were ?100 ps and ?1-2 cm, respec- tively. These values are comparable to those obtained from cosmic-ray bench tests and test beams.
