9801947 Baragiola Dr. Raul Baragiola, University of Virginia, will investigate the surface properties of ice, especially under the bombardment of ions. He has designed a series of laboratory experiments on water ice and other ices to investigate morphological and chemical effects in ices under physical conditions relevant to the surfaces of planetary satellites. The focus is on physical and chemical properties that have manifestations in the remote sensing of surfaces by optical reflectance from the ultraviolet to the infrared. The studies will simulate processes on icy satellites, especially those induced by ultraviolet radiation and ions that are also important for comets and planetary rings. Besides the fundamental interest in understanding bodies in the Solar System, the research has applications in many areas, such as remote sensing of ices on Earth, physics and chemistry of mesospheric ice grains, processing of materials by ions and photons, radiation effects in biological tissue, and exobiology.

小行星9801947 弗吉尼亚大学的Raul Baragiola博士将研究冰的表面特性，特别是在离子轰击下。 他设计了一系列关于水冰和其他冰的实验室实验，以研究在与行星卫星表面相关的物理条件下冰的形态和化学效应。 重点是通过从紫外线到红外线的光学反射对表面进行遥感时所表现出来的物理和化学性质。 这些研究将模拟结冰卫星上的过程，特别是那些由紫外线辐射和离子引起的过程，这些过程对彗星和行星环也很重要。 除了对了解太阳系天体的基本兴趣外，这项研究在许多领域都有应用，例如地球上冰的遥感，中间层冰粒的物理和化学，离子和光子对材料的处理，生物组织中的辐射效应和外太空生物学。
