  We present XMM-Newton observations of the luminous star Eta Carinae,
including a high resolution soft X-ray spectrum of the surrounding nebula
obtained with the Reflection Grating Spectrometer. The EPIC image of the field
around Eta Car shows many early-type stars and diffuse emission from hot,
shocked gas. The EPIC spectrum of the star is similar to that observed in
previous X-ray observations, and requires two temperature components. The RGS
spectrum of the surrounding nebula shows K-shell emission lines from hydrogen-
and helium-like nitrogen and neon and L-shell lines from iron, but little or no
emission from oxygen. The observed emission lines are not consistent with a
single temperature, but the range of temperatures observed is not large,
spanning ~0.15-0.6 keV. We obtain upper limits for oxygen line emission and
derive a lower limit of N/O > 9. This is consistent with previous abundance
determinations for the ejecta of Eta Car, and with theoretical models for the
evolution of massive, rotating stars.
