The city of Reno has announced some downtown street closures as NASA resumes a series of drone tests in high-density urban settings.
Beginning Friday, Lake Street will be closed from 1st to 2nd streets from 6 a.m. to 3 p.m. through June 20, and again June 23-25.
Chism Street also will be closed from Dickerson to 2nd Street from June 14-July 2.
It's part of the final stage of a four-year effort to develop a national drone traffic management system.
NASA and the Nevada Institute for Autonomous Systems conducted initial tests last month, flying drones for the first time above Reno streets beyond the operator's line of sight.
They're researching emerging technology that someday will be used to manage hundreds of thousands of small unmanned commercial aircraft delivering packages.
