VLBA St Croix Repairs

本建议描述了对圣克罗伊岛上的圣克罗伊甚大基线阵站的维修活动。圣克罗伊车站于2017年9月遭到飓风玛丽亚的破坏，随后，国会通过总统于2018年2月9日签署的2018年两党预算法（公法115-123）提供资金进行维修。该提案详细概述了计划中的活动，所有这些活动都支持将该站点恢复为世界级的工作科学观测站，并恢复VLBA的全部功能。VLBA在圣克罗伊获得的观测有助于实现天文学界制定的科学目标。该奖项反映了美国国家科学基金会的法定使命，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。

This proposal describes repairs activities to the St. Croix Very Large Baseline Array (VLBA) station on St. Croix Island. The St. Croix station was damaged by Hurricane Maria in September 2017, and, subsequently, Congress provided funding to perform repairs via the Bipartisan Budget Act of 2018 (Public Law 115-123) signed into law by the President on 9 February 2018. The proposal outlines the planned activities in detail, all of which are in support of returning the site to a world-class working science observatory, and reinstating the full capabilities of the VLBA. Observations obtained by the VLBA with St. Croix contribute to the fulfillment of scientific goals set out by astronomy communities.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.
