We present x-ray spectral analysis for the northeast and the southwest opposing jets emanating from the accreting white dwarf of the symbiotic system R Aqr. Low resolution Chandra spectra for two epochs separated by 3.3 years are fit with model spectra including X-ray emission lines of C V, C VI, N VI, O VII, and O VIII in the range of 0.2 to 1 keV. We compare derived temperature, density, and abundance parameters between both jets and between the two observations taken in September 2000 and January 2004. These parameters of the shocked-heated gas in the R Aqr jets provide insight into the origin of the jets and their evolution. We acknowledge the support of NASA contract NAS8 39073 and grant G04-5030A.
