The recurrent nova RS Ophiuchi exploded on 2006 February 12---its
first outburst since 1985. The system comprises a white dwarf near the
Chandrasekhar limit in orbit with a red giant with a massive wind.
X-ray observations began within a few days of discovery and include
data from RXTE, Swift, Chandra, and XMM-Newton. These observations,
in combination with radio observations obtained with the VLA and VLBA,
confirm the currently favoured picture for the outburst in which
ejecta from a thermonuclear runaway on the surface of the accreting
white dwarf impact ambient wind material from the red giant. X-rays
initially arose from the blast wave that reached temperatures of
$10^8$ K and exhibited prominent lines from highly ionised species of
N, O, Mg, Ne, Si, S and Fe. The momentum-conserving shock system is
analogous to that of supernova remnants, but evolving over months
rather than millennia. Subsequently, a supersoft source powered by
nuclear burning on the white dwarf surface emerged. This phase
continued until May 13, 2006 when the decay in the SWIFT count rate
indicated the SSS essentially turned off and RS Oph entered its
nebular phase. We will report on high resolution Chandra spectra
obtained at different phases of the outburst, together with an
extensive set of lower resolution SWIFT monitoring observations, that
together provide an unprecedented view of this type of nova outburst.
