Michele Bannister (UVIC) Mapping the Deep: First Discoveries from the Outer Solar System Origins Survey The exploration of the outer Solar System has reached an exciting point: we are now beginning to understand its dynamical structure, sculpted into existence by giant planet migration in the early history of the Solar System. We have designed a survey using 560 hours of CFHT time over four years to provide hundreds of new trans-Neptunian objects with exquisitely characterized, high-precision orbits. This new fully characterized wide-field survey began observations with CFHT MegaPrime in February 2013, and by its conclusion in 2016 aims to have doubled the number of trans-Neptunian objects suitable for testing models of Solar System history.
