世界标准时间 2010 年 6 月 13 日，HAYABUSA 航天器在重返地球大气层期间观察到了样品舱的亮度变化。在 13 h 52 m 01 s 到 13 h 52 m 38 s UT 期间观察到胶囊，在 13 h 52 m 19 s 和 21 s UT 之间出现三个亮度峰值。最高峰的绝对星等为 5.7(˙0.9)，时间为 13 h 52 m 18:s 6 UT。发光效率达到最大值0.89%（+1.14%，±0.50%）
The brightness variation of the sample capsule of the HAYABUSA spacecraft was observed during reentry into Earth’s atmosphere on 2010 June 13 UT. The capsule was observed from 13 h 52 m 01 s through 13 h 52 m 38 s UT, with three peaks of brightness between 13 h 52 m 19 s and 21 s UT. The absolute magnitude of the highest peak was � 5.7(˙0.9) at 13 h 52 m 18: s 6 UT. The luminous efficiency reached to the largest value of 0.89% (+1.14%, � 0.50%)
