摘要：Fractures to the orbital walls and floor must be appropriately managed to avoid severe *** results in particularly challenging anatomical *** main issues are the implant’s proper shaping,placement,and orientation onto the eye socket.A new,customized implant-shaping mould has already been developed to shape patient-specific ***,it still does not address the implant positioning in the fractured orbital cavity.

摘要：This paper presents methods of orbit transfer for small planetoids from the main belt to the future colonies on Mars using current technologies. The results show that by using nuclear weapon or even kinetic energy weapon (for retrograde bodies) asteroids with masses up to about 100 tons can be moved. Both options assume that asteroid will survive explosion.

摘要：2015年3月6日，美国航空航天局（NASA）的“黎明”（Dawn）小行星探测器抵达谷神星，从而成为首个探测矮行星的探测器、首个探测谷神星的探测器，还成为首个探测两个独立地外天体的探测器。“黎明”于2007年9月27日由德尔他-2火箭发射。该项目由喷气推进实验室（JPL）管理，轨道科学公司（orbital Sciences Corporation）负责探测器的设计和制造，加州大学洛杉矶分校负责任务的科学运行。“黎明”项目的总成本预计为4.46亿美元。
