  We report the discovery of pulsed X-ray emission from the compact object CXOU
J112439.1-591620 within the Galactic supernova remnant G292.0+1.8 using the
High Resolution Camera on the Chandra X-Ray Observatory. The X-ray period is
consistent with the extrapolation of the radio period and spindown rate of PSR
J1124-5916. The X-ray pulse is single peaked and broad. There is no optical
counterpart to a limit of M_V ~ 26. The pressure in the pulsar wind nebula is
considerably less than that in the reverse-shock-heated ejecta and
circumstellar medium, indicating that the reverse shock has not yet begun to
interact with the nebula.
