We present HETG/ACIS-S spectra from our Chandra observation of the Vela pulsar and its synchrotron nebula. The 40 ksec observation was made using the ACIS-S in continuous clocking mode, which sacrifices one spatial dimension for more precise timing. We will show the one-dimensional profile of the nebula and pulsar. We will present the results of analysis of pulse-phased ACIS and HETG spectra of the pulsar, as well as ACIS spectra of the nebula. We also examine the unpulsed emission from Vela to search for identifiable atmospheric effects from the neutron star surface and test for deviations from a blackbody. This work is supported under the contract SAO SV1-61010.
