    报告1时间:2018118日(周四) 上午9:30-10:20

    报告地点:地质斋(主楼308

    报告题目:Water, Ice, and Hydroxyl in the Main Belt

    报告摘要:Water-and Organics-rich objects are of intense interest to the planetary science community, and are high-priority targets for spacecraft visits and sample return. However, such visits are rare commodities, and remote sensing via telescopic observations are necessary to obtain the context required for understanding spacecraft measurements. Over the past decade, we have observed hundreds of objects at wavelengths diagnostic for water and organic material. I will present our current understanding of water, hydroxyl, and ice on asteroids, including the ways these objects are and aren't represented in the meteorite collection.

    报告Spectroscopy of Phobos and Deimos

    报告地点:地质斋(主楼308

    报告摘要:The moons of Mars are of uncertain origin, with some data suggesting they are captured asteroids and other data suggesting they formed after an impact into Mars. Thus far, all of our information about these bodies has been collected remotely, whether from telescopes or spacecraft. I will discuss what we know about Phobos and Deimos from their reflectance properties, including a history of their observations and what is planned for the future.

    报告地点:地质斋(主楼308

    报告题目: Hydrated NEOs

    报告摘要: The near-Earth objects (NEOs) are the connection between meteorites and objects in the main asteroid belt. In terms of the volatiles they carry, however, we know less than we do about either meteorites or main-belt objects. I will discuss what we have directly measured, ways of indirectly detecting their hydrated minerals, and the number of objects expected to have hydrated minerals (which may make excellent targets for science or mining missions).
