  We present new infrared imaging of the NGC 2264 G protostellar outflow
region, obtained with the InfraRed Array Camera (IRAC) on-board the Spitzer
Space Telescope. A jet in the red outflow lobe (eastern lobe) is clearly
detected in all four IRAC bands and, for the first time, is shown to
continuously extend over the entire length of the red outflow lobe traced by CO
observations. The redshifted jet also extends to a deeply embedded Class 0
source, VLA 2, confirming previous suggestions that it is the driving source of
the outflow (Gomez et al. 1994). The images show that the easternmost part of
the redshifted jet exhibits what appear to be multiple changes of direction. To
understand the redshifted jet morphology we explore several mechanisms that
could generate such apparent changes of direction. From this analysis, we
conclude that the redshifted jet structure and morphology visible in the IRAC
images can be largely, although not entirely, explained by a slowly precessing
jet (period ~8000 yr) that lies mostly on the plane of the sky. It appears that
the observed changes in the redshifted jet direction may be sufficient to
account for a significant fraction of the broadening of the outflow lobe
observed in the CO emission.
