The research supported by this grant will utilize recent advances in technology and orbital studies to perform the first systematic physical study of small asteroids in the main belt. Such a study is critically needed to investigate the source region for the population of near-Earth asteroids and the collisional evolution processes within the asteroid belt. The observations, using telescopes at the McGraw-Hill Observatory and the Lowell Observatory, will reveal the rotation rates, shapes, basic compositions, and surface properties of approximately 30 small main belt asteroids. Knowledge of the rotation rates and shapes of these objects will provide strong constraints for asteroid collisional evolution models.

这笔赠款支持的研究将利用最新的技术和轨道研究进展，对主带中的小型小行星进行首次系统的物理研究。 迫切需要这样的研究来调查近地小行星种群的源区以及小行星带内的碰撞演化过程。 使用麦格劳-希尔天文台和洛厄尔天文台的望远镜进行的观测将揭示大约 30 颗小型主带小行星的旋转速度、形状、基本成分和表面特性。 了解这些物体的旋转速率和形状将为小行星碰撞演化模型提供强有力的约束。
