We have studied the fine structure of the active H2O supermaser emission region in Orion KL with an angular resoln. of 0.1 mas. We found central features suggestive of a bipolar outflow, bullets, and an envelope which correspond to the earliest stage of low-mass star formation. The ejector is a bright compact source ?0.05 AU in size with a brightness temp. Tb ~ 1017 K. The highly collimated bipolar outflow ~30 has a velocity vej ~ 10 km s-1, a rotation period of ~0.5 yr, a precession period of ~10 yr, and a precession angle of ~33 Deg. Precession gives rise to a jet in the shape of a conical helix. The envelope amplifies the radio emission from the components by ~3 orders of magnitude at a velocity v = 7.65 km s-1.
