Hayabusa2 Mission Re-evaluates Asteroid KY26 Approach Due to New Observations

New observations of asteroid KY26, the target for JAXA's Hayabusa2 extended mission, reveal a small non-gravitational trajectory component and higher-than-expected surface temperatures. These findings, suggesting radiation-pressure and thermal-recoil effects over buried water ice, are prompting mission engineers to refine scientific questions and operational strategies for approaching the rapidly rotating object. This re-evaluation is crucial for planetary defense studies.
