Kevin B. Stevenson, Daniel Fabrycky, Robert Jedicke, William Bottke,, Larry Denneau

TL;DR
NEOKepler is a proposed mission utilizing Kepler's large field of view to significantly enhance the detection of near-Earth objects and potentially hazardous objects, improving discovery rates and understanding of NEO populations.
Contribution
This paper introduces NEOKepler, a novel survey concept leveraging Kepler's capabilities to discover more NEOs and PHOs, and explores its feasibility and scientific benefits.
Findings
Estimated detection of ~150 new NEOs in 12 months
Approximately 50 new PHOs could be identified annually
Kepler's orbit allows detection of objects inside Earth's orbit
Abstract
We propose a new Kepler mission, called NEOKepler, that would survey near Earth's orbit to identify potentially hazardous objects (PHOs). To understand its surveying power, Kepler's large field of view produces an 'etendue' (A*Omega) that is 4.5 times larger than the best survey telescope currently in operation. In this paper, we investigate the feasibility of NEOKepler using a double "fence post" survey pattern that efficiently detects PHOs. In a simulated 12-month survey, we estimate that NEOKepler would detect ~150 new NEOs with absolute magnitudes of less than 21.5, ~50 of which would be new PHOs. This would increase the annual PHO discovery rate by at least 50% and improve upon our goal of discovering 90% of PHOs by the end of 2020. Due to its heliocentric orbit, Kepler would also be sensitive to objects inside Earth's orbit, discovering more objects in its first year than are…
