NASA will be back in Reno Friday testing out drones in high density areas.

You may remember NASA did similar tests last month in downtown Reno.

NASA says Reno offered an ideal testing ground with tall buildings to navigate around and a highly variable climate.

Because of these tests, Lake Street will be closed from 1st to 2nd Streets from 6 a.m. to 3 p.m. Friday through Thursday, and then again from next Sunday the 23rd through Tuesday the 25th.

City Plaza will be restricted to Nevada Institute for Autonomous Systems use, and will be fenced off to the general public. 

NASA says the agency’s research into drone traffic management focuses on operations within a city, at an altitude of 200 to 400 feet, and the unique challenges presented when remote pilots fly beyond visual line of sight in an urban area.

NASA says the goal is to understand how a nationwide system for drones can safely integrate remotely-piloted aircraft into low-altitude airspace.

The City of Reno is currently participating in three drone testing programs, with Reno being the only city in the country involved in all three testing programs.
