THE SPACE BEYOND THE ORBIT OF NEPTUNE IS INHABITED BY PLANETESIMALS LEFT OVER FROM OUR SOLAR SYSTEM S FORMATION 4.5 BILLION YEARS AGO. THESE TRANS-NEPTUNIAN OBJECTS (TNOS) PRESERVE MANY CLUES ABOUT THE EVOLUTION OF OUR PLANETARY SYSTEM. OUR UNDERSTANDING OF THE SMALLEST (AND MOST NUMEROUS) TNOS IS GENERALLY DRIVEN BY THEORETICAL MODELS INDIRECT EVIDENCE AND ANALYSIS OF THE SPARSE EXISTING DATA. OUR TEAM HAS BEEN ALLOCATED 46.5 NIGHTS ON THE NOAO/CTIO 4-METER BLANCO TELESCOPE WITH DECAM TO CARRY OUT THE DEEP ECLIPTIC EXPLORATION PROJECT (DEEP). THIS NOAO SURVEY PROGRAM WILL BE EXECUTED ACROSS SIX SEMESTERS (2019A-2021B). THE GOALS OF THIS PROJECT ARE (1) TO MEASURE THE SIZE DISTRIBUTION AND PHYSICAL PROPERTIES OF 5000 TNOS DOWN TO VR=27 THROUGH SHIFTAND- STACK TECHNIQUES; (2) TO MEASURE THE SIZE DISTRIBUTION COLORS AND SHAPE DISTRIBUTION OF TNOS AS A FUNCTION OF DYNAMICAL CLASS; (3) TO MEASURE THE COLORS SIZE DISTRIBUTION AND SHAPE DISTRIBUTION OF SOME 15 000 MAIN BELT ASTEROIDS; AND (4) TO ENABLE A RICH ARRAY OF OTHER SCIENCE INVESTIGATIONS. OUR RESULTS WILL HELP ELUCIDATE THE COMPOSITION AND STRUCTURE OF THE OUTER SOLAR SYSTEM AND THE ORIGIN OF OUR PLANETARY SYSTEM. OUR TEAM HAS WORLD-CLASS EXPERTISE IN ALL THE TECHNICAL AND SCIENTIFIC AREAS OF THIS PROJECT AND IN THIS PROPOSAL WE DEMONSTRATE PRELIMINARY RESULTS FROM OUR APRIL 2019 OBSERVING RUN. OUR OBSERVING PLANNING DATA PROCESSING AND PROJECT MANAGEMENT TASKS ARE ALL WELL-DEFINED AND WELL-HONED AND THIS PROJECT WILL PRODUCE AT LEAST EIGHT PRIMARY SCIENCE PAPERS. THIS PROGRAM IS RELEVANT TO THE SSO PROGRAM WHICH HAS AS ITS PRIMARY MISSION "GROUND-BASED ... ASTRONOMICAL OBSERVATIONS OF BODIES IN OUR SOLAR SYSTEM. PROPOSALS ARE SOLICITED FOR OBSERVATIONS ... THAT CONTRIBUTE TO THE UNDERSTANDING OF THE NATURE AND EVOLUTION OF THE SOLAR SYSTEM AND ITS INDIVIDUAL CONSTITUENTS." THE WORK THAT WE WILL CARRY OUT IN THIS NOAO SURVEY PROGRAM WILL ELUCIDATE THE NATURE AND EVOLUTION OF THE SOLAR SYSTEM AND OF TNOS AS DESCRIBED ABOVE.
