  The Mars Odyssey spacecraft carries two experiments which are capable of
detecting cosmic gamma-ray bursts and soft gamma repeaters. Since April 2001
they have detected over 275 bursts and, in conjunction with the other
spacecraft of the interplanetary network, localized many of them rapidly and
precisely enough to allow sensitive multi-wavelength counterpart searches. We
present the Mars Odyssey mission and describe the burst capabilities of the two
experiments in detail. We explain how the spacecraft timing and ephemeris have
been verified in-flight using bursts from objects whose precise positions are
known by other means. Finally, we show several examples of localizations and
discuss future plans for the Odyssey mission and the network as a whole.
