  We present a near-IR survey of the Trapezium Cluster and inner Orion Nebula
using the NASA/ESA/CSA James Webb Space Telescope. The survey with the NIRCam
instrument covers 10.9 x 7.5 arcminutes (~1.25 x 0.85 pc) in twelve wide-,
medium-, and narrow-band filters from 1-5 microns and is diffraction-limited at
all wavelengths, providing a maximum spatial resolution of 0.063 arcsec at 2
microns, corresponding to ~25 au at Orion. The suite of filters chosen was
designed to address a number of scientific questions including the form of the
extreme low-mass end of the IMF into the planetary-mass range to 1 Jupiter mass
and below; the nature of ionised and non-ionised circumstellar disks and
associated proplyds in the near-IR with a similar resolution to prior HST
studies; to examine the large fragmented outflow from the embedded BN-KL region
at very high resolution and fidelity; and to search for new jets and outflows
from young stars in the Trapezium Cluster and the Orion Molecular Cloud 1
behind. In this paper, we present a description of the design of the
observational programme, explaining the rationale for the filter set chosen and
the telescope and detector modes used to make the survey; the reduction of the
data using the JWST pipeline and other tools; the creation of large colour
mosaics covering the region; and an overview of the discoveries made in the
colour images and in the individual filter mosaics. Highlights include the
discovery of large numbers of free-floating planetary-mass candidates as low as
0.6 Jupiter masses, a significant fraction of which are in wide binaries; new
emission phenomena associated with the explosive outflow from the BN-KL region;
and a mysterious "dark absorber" associated with a number of disparate features
in the region, but which is seen exclusively in the F115W filter. Further
papers will examine those discoveries and others in more detail.
