  Presented here are high spatial and spectral resolution Chandra X-ray
observations of the famous interacting galaxy pair, the Mice, a system similar
to, though less evolved than, the well-known Antennae galaxies. Previously
unpublished ROSAT HRI data of the system are also presented. Starburst-driven
galactic winds outflowing along the minor axis of both galaxies (but
particularly the northern) are observed, and spectral and spatial properties,
and energetics are presented. That such a phenomenon can occur in such a
rapidly-evolving and turbulent system is surprising, and this is the first time
that the very beginning - the onset, of starburst-driven hot gaseous outflow in
a full-blown disk-disk merger has been seen. Point source emission is seen at
the galaxy nuclei, and within the interaction-induced tidal tails. Further
point source emission is associated with the galactic bar in the southern
system. A comparison of the source X-ray luminosity function and of the diffuse
emission properties is made with the Antennae and other galaxies, and evidence
of a more rapid evolution of the source population than the diffuse component
is found. No evidence for variability is found between the Chandra and previous
observations.
