2044: A DEEP Space Odyssey

Discovering Extra-Neptunian and Extrasolar Phenomena (DEEP) is an exciting long-term deep-space mission consisting of two long-endurance probes. Proposed to launch in 2044, DEEP will be developed to analyze the nature and composition of a selected Kuiper Belt Object (KBO), the interstellar medium and the effects of interstellar space on distant objects and spacecrafts. Consisting of the Spectral Observation, Detection and Analysis (SODA) main bus and the integrated Perforation and Orbital Propulsion (POP) impactor module, DEEP uses key technology demonstrated on successful historical missions such as New Horizons, Voyager, Spitzer Space Telescope and Deep Impact. The DEEP-1 probe will encounter and study a target-KBO (TKBO) during flyby, using the POP module as a kinetic impactor to reveal surface and subsurface composition through a visually resolvable crater and optically thick ejecta plume. An onboard 500 mm primary telescope will conduct visual and spectral analysis of a target-KBO’s (TKBO) atmosphere, surface and subsurface to identify the distribution of these chemicals, augmented by the primary and secondary instruments. Following the TKBO flyby, DEEP-1 will continue to coast towards the heliopause, where it will continue to research the exposure and nature of the interstellar medium. DEEP-2 will use a different trajectory to quickly travel through the Kuiper Belt, allowing for expedited heliopause investigation and cross-referencing with DEEP-1 to verify instrument readings. DEEP-2 replaces the POP impactor mission with the integration of deployable CubeSats for extended exploration within the scientific community along key phases of the trajectory. DEEP employs a sophisticated harmony of powerful, lightweight instruments, durable and reliable subsystems, and a carefully selected trajectory harmonious with the gas giants. As several outer planets align for gravitational assists in 2044, a rare opportunity exists to complete this mission using heritage technology - improved upon for the scope of this modern space odyssey.
