We propose to use STIS to obtain the first FUV long-slit spectrum of DG Tau's jet. The classical T Tauri star DG Tau shows signatures of magnetic activity, accretion, a circumstellar disk and outflows. The detection of soft X-ray emission from hot plasma with temperatures above 10^6 K within DG Tau's jet at a few tens of AU from the power source, distinctly different from coronal emission, challenges current jet theories, since observations and modeled scenarios concentrated on warm material with temperatures up to a few 10^4 K. With the slit oriented along the jet axis and supplementary broad band ACS/SBC FUV images, we will use the C IV emission line doublet {peak formation temperature 10^5 K} to measure, for the first time, the kinematics of the intermediate temperature gas along the jet axis, which is not possible with any other instrument. Our goals are to find {1} the relation of the intermediate temperature material to the hot X-ray emitting material, {2} the correlation of temperature and velocity in stellar jets, and {3} the heating source of the hotter material.;
