Sep 2017 VLASS Survey begins (2017B) after passing design reviews

The SSG, with the support of the NRAO Survey Design Group (SDG), formulated the survey design and plan and the drafts of the proposals. The SDG and the Technical Working Group of the SSG formulated the detailed Technical Implementation Plan (TIP). A NRAO technical and science review in late 2014 will provide input to the Community Review panel, which met in March 2015 to provide the "go/no-go" decision on the VLASS. Following the posting of the final draft on Jan 1 2015, there was a 1.5 month period during which the community commented on the final VLASS proposal, and all comments from this period were provided as input to the Community Review panel.  The Community Review panel recommended proceeding with the ALL-SKY survey component, and advised that the DEEP survey component be separately submitted as a large P.I. proposal. We are in the process of setting up and staffing the NRAO VLASS project office, with the goal of starting a pilot survey in May 2016, and the full survey in late 2017. A series of preliminary and critical design and readiness reviews will occur in 2016 and 2017 leading up to the survey start.
