This award will make the Las Cumbres Observatory (LCO) global network of optical telescopes available to the US astronomical community over a period of 3 years. The network consists of two 2m telescopes, eleven 1m telescopes, and ten 0.4m telescopes at multiple locations around the world. Broader impacts of the work include student and postdoctoral researcher training as well as public outreach. In addition to providing unique resources to scientists, LCO runs a vibrant education program. LCO lowers barriers for both science and education observers. Observations can be requested from anywhere in world with an approved observing program and access to the internet. This award advances the goals of the Windows on the Universe Big Idea via LCO’s strong relevance to Multi-Messenger Astrophysics. Observing time will be made available over 6 semesters, with 200 hours/semester on the 2m telescopes and 1250 hours/semester on the 1m telescopes, plus 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 follow-up opportunities for discoveries by NSF's Vera Rubin Observatory.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项将使Las Cumbres天文台（LCO）的全球光学望远镜网络在3年内可供美国天文学界使用。该网络由两个2米望远镜，11个1米望远镜和10个0.4米望远镜组成，分布在世界各地。这项工作的更广泛影响包括学生和博士后研究人员培训以及公众宣传。除了为科学家提供独特的资源外，LCO还开展了一项充满活力的教育计划。 LCO降低了科学和教育观察员的障碍。可以从世界上任何地方请求观察，并通过批准的观察计划和互联网访问。该奖项通过LCO与多信使天体物理学的密切相关性推进了宇宙大创意窗口的目标。观测时间将在6个学期内提供，200小时/学期在2 m望远镜上，1250小时/学期在1 m望远镜上，加上社区参与关键项目。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。获得这些望远镜将允许美国社区开展有趣的个人项目，加强其他望远镜正在进行的调查，并为NSF的Vera Rubin天文台的发现提供后续机会。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
