95-30282 Binzel Dr. Binzel will carry out a 5-year project of infrared spectroscopy of asteroids using a new, state-of-the-art spectrograph and the NASA Infrared Telescope Facility, Mauna Kea, HI. The spectrograph covers the wavelength range of 0.9 to 1.8 microns and will permit pushing the observational limits for observing asteroids by at least two magnitudes fainter than previous observations. The spectrograph was designed, purchased, and tested by the Principal Investigator through a previous NSF Presidential Young Investigator award (AST 90-58462). The scientific goals of the observations are manifold. They include identifying asteroid analogs for ordinary chondrite and basaltic achondrite meteorites, sampling the range of compositional properties of near-Earth asteroids, and investigating unusual mineralogies among the asteroids. Supporting visible wavelength spectra will be obtained via a separate NASA-funded observing program at Kitt Peak, AZ. The ultimate objective of the investigation is to improve our knowledge of the relationship between the principal classes of meteorites and asteroids, and to advance our understanding of the formation and evolution of the planets ***

95-30282 Binzel Binzel博士将使用一台新的、最先进的摄谱仪和美国宇航局位于夏威夷莫纳克亚的红外望远镜设施，开展一个为期5年的小行星红外光谱学项目。 摄谱仪覆盖0.9至1.8微米的波长范围，将使观测小行星的观测极限比以前的观测至少暗两个星等。 光谱仪是由首席研究员通过先前的NSF总统青年研究员奖（AST 90-58462）设计，购买和测试的。 观测的科学目标是多方面的。 它们包括识别普通球粒陨石和玄武质无球粒陨石的小行星类似物，对近地小行星的成分特性范围进行采样，并调查小行星中不寻常的矿物。 支持可见波长光谱将通过一个单独的美国宇航局资助的观测计划在基特峰，亚利桑那州。 调查的最终目的是增进我们对主要类别的陨石和小行星之间关系的了解，并增进我们对行星形成和演变的理解 *
