This award will make the Las Cumbres Observatory Global Telescope (LCOGT) network of optical telescopes available to the US astronomical community over a period of 3.5 years. The network consists of two 2m telescopes, 9-12 1m telescopes, and many 0.4m telescopes at multiple locations around the world. Broader impacts of the work include training of students and postdocs, and public outreach. LCOGT provides telescope time and other resources for many astronomy education programs, including the Faulkes Telescope Project, the International Astronomical Search Collaboration, Hands On Universe, Universe Awareness, Universe in the Classroom, Galileo Teacher Training Program, Astronomers without Borders, Our Solar Siblings, and Astrofactum.Observing time will be made available over 7 semesters, with 214 hours/semester on the 2m telescopes and 1287 hours/semester on the 1m telescopes, plus some community involvement in key projects. Unique capabilities of the facility include continuous monitoring (24H/day), flexible cadence, long-term stable observations, and rapid target-of-opportunity response. Access to the telescopes will allow interesting individual projects to be conducted by the US community, enhance on-going surveys at other telescopes, and provide opportunities to prepare for NSF's Large Synoptic Survey Telescope (currently under construction).

该奖项将使美国天文界在3.5年内可以使用Las Cumbres天文台全球望远镜（LCOGT）光学望远镜网络。该网络由两个2米望远镜，9-12个1米望远镜和许多0.4米望远镜组成，分布在世界各地的多个地点。这项工作的更广泛影响包括对学生和博士后的培训以及公共宣传。LCOGT为许多天文学教育项目提供望远镜时间和其他资源，包括Faulkes望远镜项目，国际天文学搜索合作，Hands On Universe，Universe Awareness，Universe in the Classroom，Galileo Teacher Training Program，Astronomers Without Borders，Our Solar Sixth和Astrofactum。观测时间将在7个学期内提供，2 m望远镜每学期214小时，1 m望远镜每学期1287小时，加上一些社区参与的关键项目。该设施的独特功能包括连续监测（24小时/天），灵活的节奏，长期稳定的观察和快速的目标机会响应。进入望远镜将允许美国社区进行有趣的个人项目，加强其他望远镜正在进行的调查，并为NSF的大型综合巡天望远镜（目前正在建设中）做准备提供机会。
